New world record for C 130 J transport aircraft. Indian Air Force lands C 130 J at Daulat Beg Oldie, altitude of 16,600 feet.
IAF Statement: In a significant capability demonstration move by the IAF, a C 130J-30 Super Hercules aircraft land...ed at Daulat Beg Oldie (DBO), the highest airstrip in the world at 0654 hrs today. The Commanding Officer Group Captain Tejbir Singh and the crew of the "Veiled Vipers" along with senior officer of Air Headquarters touched down on the DBO airstrip located at 16614 feet (5065 meters) in the Aksai Chin area after taking off from their home base at Hindon.
Today's achievement will enable the forces to exploit the inherent advanced capabilities of the aircraft by increased capability to induct troops, improve communication network and also serve as a great morale booster for maintenance of troops positioned there. It is also a projection of the fact that the IAF is capable of operating in such inhospitable terrain in support of the Indian Army.

Aerodynamic maneuverability vs supermaneuverability

The Eurofighter Typhoon is an example of a supermaneuverable aircraft.

A pair of F-22 Raptor fighters. With thrust vectoring and a thrust-to-weight ratio of 1.26 at 50% fuel, it is the first production aircraft in the U.S. arsenal to be supermaneuverable.

Traditional aircraft maneuvering is accomplished by altering the flow of air passing over the control surfaces of the aircraft - the ailerons, elevators, flaps, air brakes and rudder. Some of these control surfaces can be combined—such as in the "ruddervators" of a V-tail configuration—but the basic properties are unaffected. When a control surface is moved to present an angle to the oncoming airflow, it deflects the airstream and, by Newton's Third Law, an equal opposing force is applied by the air to the control surface and thus to the aircraft. The angle of control surface deflection and resulting directional force on the aircraft are controlled by the pilot to maintain the desired attitude, such as pitch, roll and heading, and also to perform aerobatic maneuvers that rapidly change the aircraft's attitude. For traditional maneuvering control to be maintained, the aircraft must maintain sufficient forward velocity and a sufficiently low angle of attack to provide airflow over the wings (maintaining lift) and also over its control surfaces. As airflow decreases so does effectiveness of the control surfaces and thus the maneuverability. On the other hand, if the angle of attack exceeds its critical value, the airplane will stall. Pilots are trained to avoid stalls during aerobatic maneuvering and especially in combat, as a stall can permit an opponent to gain an advantageous position while the stalled aircraft's pilot attempts to recover.
The speed at which an aircraft is capable of its maximum aerodynamic maneuverability is known as the corner airspeed; at any greater speed the control surfaces cannot operate at maximum effect due to either airframe stresses or induced instability from turbulent airflow over the control surface. At lower speeds the redirection of air over control surfaces, and thus the force applied to maneuver the aircraft, is reduced below the airframe's maximum capacity and thus the aircraft will not turn at its maximum rate. It is therefore desirable in aerobatic maneuvering to maintain corner velocity.
In a supermaneuverable aircraft, the pilot can maintain a high degree of maneuverability below corner velocity, and at least limited attitude control without altitude loss below stall speed. Such an aircraft is capable of maneuvers that are impossible with a purely aerodynamic design. More recently, increased use of jet-powered, instrumented unmanned vehicles ("research drones") has increased the potential flyable angle of attack beyond 90 degrees and well into the post-stall safe flight domains, and has also replaced some of the traditional uses of wind tunnels

Supermaneuverability(cobra & Super Cobra)

Pugachev's Cobra maneuver is one of the tests for supermaneuverability. Here performed by a Su-27.

Supermaneuverability is the quality of aircraft defined as a threshold of attitude control exceeding that which is possible by pure aerodynamic maneuverability; in other words, a controlled loss of control beyond normal abilities. It is a trait of some advanced fourth-generation and 4.5-generation fighter aircraft which has become standard in fifth-generation aircraft such as the F-22 Raptor and the Russian Sukhoi PAK FA (T-50), the Su-30 and the Su-30MKI. Post-stall technology is increasingly used in recent years to advance supermaneuverability by the use of vectored thrust in 4.5 and 5th generation aircraft.

Capabilities of Su-30mki

Airframe

Su-30MKI's canards and thrust-vectoring nozzles are two of the most prominent developments over the basic MK variant.

The Su-30MKI is a highly integrated twin-finned aircraft. The airframe is constructed of titanium and high-strength aluminium alloys. The engine nacelles are fitted with trouser fairings to provide a continuous streamlined profile between the nacelles and the tail beams. The fins and horizontal tail consoles are attached to tail beams. The central beam section between the engine nacelles consists of the equipment compartment, fuel tank and the brake parachute container. The fuselage head is of semi-monocoque construction and includes the cockpit, radar compartments and the avionics bay.

Cockpit and ergonomics

Flight control

Su-30MKI flying inverted

The aircraft has a fly by wire (FBW) with quadruple redundancy. Depending on the flight conditions, signals from the control stick position transmitter or the FCS will be coupled to the remote control amplifiers. These signals are combined with feedback signals fed by acceleration sensors and rate gyros. The resultant control signals are coupled to the high-speed electro-hydraulic actuators of the elevators, rudders and the canard. The output signals are compared and, if the difference is significant, the faulty channel is disconnected. FBW is based on a stall warning and barrier mechanism which prevents development of aircraft stalls through a dramatic increase in the control stick pressure. This allows a pilot to effectively control the aircraft without running the risk of reaching the limit values of angle of attack and acceleration. Although the maximum angle of attack is limited by the canards the FBW acts as an additional safety mechanism.
Phase 3 of further development of the MKI, will integrate avionic systems being developed for the Indo-Russian Fifth Generation Fighter Aircraft program.

General features

The displays include a highly customized version of the Israeli Elbit Su 967 head-up display consisting of bi-cubic phase conjugated holographic displays and seven liquid crystal multifunction displays, six 127 mm x 127 mm and one 152 mm x 152 mm. The HUD was widely misreported to be the VEH 3000 from Thales. Variants of the same HUD have also been chosen for the IAF's Mikoyan MiG-27 and SEPECAT Jaguar upgrades, on grounds of standardization. Flight information is displayed on four LCD displays which include one for piloting and navigation, a tactical situation indicator, and two for display systems information including operating modes and overall operation status. The rear cockpit is fitted with a larger monochromatic screen display for the air-to-surface missile guidance. The Su-30MKI on-board health and usage monitoring system (HUMS) monitors almost every aircraft system and sub-system including the avionics sub-systems. It can also act as an engineering data recorder
Beginning in 2010, HUDs and Multi-Function Displays (MFD) will be provided by the Delhi-based Samtel Display Systems. These are indigenously designed and built and are not part of a joint foreign venture.

Navigation

The aircraft is fitted with a satellite navigation system (A-737 GPS compatible), which permits it to make flights in all weather, day and night. The navigation complex includes the high accuracy SAGEM Sigma-95 integrated global positioning system and ring laser gyroscope inertial navigation system.

Pilot ejection

The crew are provided with zero-zero KD-36DM ejection seats. The rear seat is raised for better visibility. The cockpit is provided with containers to store food and water reserves, a waste disposal system and extra oxygen bottles. The KD-36DM ejection seat is inclined at 30°, to help the pilot resist aircraft accelerations in air combat.

Aerodynamics

Su-30MKI aerodynamic configuration is an unstable longitudinal triplane. The canard increases the aircraft lifting ability and deflects automatically to allow high angle-of-attack (AoA) flights allowing it to perform Pugachev's Cobra. The integral aerodynamic configuration combined with thrust vectoring results in extremely capable maneuverability, taking off and landing characteristics. This high agility allows rapid deployment of weapons in any direction as desired by the crew. The canard notably assists in controlling the aircraft at large angles-of-attack and bringing it to a level flight condition.

Radar

The forward-facing NIIP N011M Bars (Panther) is a powerful integrated passive electronically scanned array radar. The N011M is a digital multi-mode dual frequency band radar. The N011M can function in air-to-air and air-to-land/sea mode simultaneously while being tied into a high-precision laser-inertial or GPS navigation system. It is equipped with a modern digital weapons control system as well as anti-jamming features. N011M has a 400 km search range and a maximum 200 km tracking range, and 60 km in the rear hemisphere. The radar can track 15 air targets and engage 4 simultaneously. These targets can even include cruise missiles and motionless helicopters. The Su-30MKI can function as a mini-AWACS as a director or command post for other aircraft. The target co-ordinates can be transferred automatically to at least four other aircraft. The radar can detect ground targets such as tanks at 40–50 km. The Bars radar will be replaced by Zhuk-AESA in all Su-30MKI aircraft.

Variants	Sukhoi Su-30MKM

The Sukhoi Su-30MKI (NATO reporting name: Flanker-H) is a Fourth-generation air superiority fighter developed by Russia's Sukhoi and assembled under licence by India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF). A variant of the Sukhoi Su-30, it is a heavy, all-weather, long-range fighter.
Development of the variant started after India signed a deal with Russia in 2000 to manufacture 140 Su-30 fighter jets. The first Russian-made Su-30MKI variant was accepted into the Indian Air Force in 2002,while the first indigenously assembled Su-30MKI entered service with the IAF in 2004. In 2007, the IAF ordered 40 additional MKIs. The IAF had 157 Su-30MKIs in service as of January 2013; it plans to have a fleet of 272. The Su-30MKI is expected to form the backbone of the Indian Air Force's fighter fleet to 2020 and beyond.
The aircraft is tailor-made for Indian specifications and integrates Indian systems and avionics as well as French and Israeli subsystems. It has abilities similar to the Sukhoi Su-35 with which it shares many features and components. 

Designing of INS vikramaditya

The ship will be operated in a STOBAR configuration, with a 14.3° bow ski-jump ramp and three arrestor wires on the stern of the angled deck. This will allow the operation of MiG-29K and Sea Harrier aircraft. The maximum take-off length for the MiG-29K on Vikramaditya will be between 160–180 metres.
An added advantage of the Admiral Gorshkov platform is its superstructure profile that has the potential to accommodate powerful planar or phased array radar systems with the “billboard style” antennae, which was first observed on the United States Navy's USS Long Beach, along with extensive command and control facilities to conduct an aerial campaign. The ship is also projected to be equipped with a robust combination of air defence weaponry, such as a SAM and/or a CIWS.

Kamov Ka-31 "Helix" are to be based on the INS Vikramaditya in an airborne early warning role.

The hull design is based on the earlier Admiral Gorshkov, launched in 1982, but it will be larger with a full load displacement. The conversion plans for the aircraft carrier involve all the armament, including the P-500 Bazalt cruise missile launchers and the four Antey Kinzhal surface-to-air missile launchers fitted on the front, to be removed to make way for a 14.3º bow ski-jump. Two restraining stands will also be fitted, allowing combat aircraft to reach full power before making a ski jump-assisted short take-off. The ability to launch only one aircraft at a time might prove to be a hindrance. Under the modernisation plan, the 20-ton capacity elevator beside the ship's island superstructure will remain unchanged, but the aft lift will be enlarged and its lift capacity increased to 30 tons. Three arresting gears would be fitted on the aft part of the angled deck. Navigation and carrier-landing aids would be refitted to support fixed-wing STOBAR (Short Take-Off But Arrested Recovery) operations including the LAK optical-landing system.

Artist concept of the Vikramaditya operating as a STOBAR carrier

The eight boilers are being removed and converted to take diesel fuel instead of furnace fuel oil and modern oil-water separators as well as a sewage treatment plant are being incorporated to meet international standards. She is also being fitted with six new Italian-made Wärtsilä 1.5 MW diesel generators, a Global Marine communications system, Sperry Bridgemaster navigation radar, a new telephone exchange, new data link and an IFF Mk XI system. Hotel services are being improved with new water-producing plants as well as York International refrigeration and air conditioning. A new galley is being installed together with improved domestic services and accommodation for 10 female officers.
Though the official expected life span of the ship is 20 years, experts suggest it could actually be a minimum of 30 years from the time of commissioning. On completion of the modernisation, over 70 percent of the ship and her equipment will be new and the remainder will have been refurbished.

Engine of LCA TEJAS

General Electric F404-IN20 engine for the eight pre-production LSP aircraft and two naval prototypes

Initially, it was decided to equip the prototype aircraft with the General Electric F404-GE-F2J3 afterburning turbofan engine. Simultaneously, in 1986, a parallel programme to develop an indigenous powerplant was also launched. Led by the Gas Turbine Research Establishment, the GTRE GTX-35VS, named "Kaveri", was expected to replace the F404 on all production aircraft. However, progress in the Kaveri development programme was slowed by technical difficulties.
Development snags with the Kaveri resulted in the 2003 decision to procure the uprated F404-GE-IN20 engine for the eight pre-production LSP aircraft and two naval prototypes. General Electric was awarded a US$105 million contract in 2004 for development engineering and production of 17 -IN20 engines, delivery of which began in 2006. The F404-GE-IN20 was trial-installed on the Tejas and the engine generated more than 19,000 pounds (85 kN) uninstalled thrust and completed 330 hours of Accelerated Mission testing, equivalent of 1,000 hours of flight operation. In 2007, an additional 24 F404-IN20 afterburning engines were ordered to power the first operational squadron of Tejas fighters.^[26]
In mid-2004, the Kaveri failed its high-altitude tests in Russia, ending the last hopes of introducing it with the first production Tejas aircraft.^{[N 6]} In February 2006, the ADA awarded a contract to the French aircraft engine company Snecma for technical assistance in working out the Kaveri's problems.^[7] The Kaveri engine based on Snecma’s new core, an uprated derivative of the M88-2 engine that powers the French Rafale fighter, providing 83–85 kilonewtons (kN) of maximum thrust was being considered a third option by DRDO. This led the IAF to object that since Snecma had already developed the core of the engine, the DRDO will not be participating in any joint development but merely providing Snecma with an indigenous stamp.^[27]
In 2008, it was announced that the Kaveri would not be ready in time for the Tejas, and that an in-production powerplant would have to be selected^[28] in the 95 to 100 kilonewton (kN) (21,000–23,000 lbf) range to allow the aircraft to perform combat maneuvers with optimal weapons load. The contenders were the Eurojet EJ200 and the General Electric F414.^[29] IAF sources said that the airframe will have to be redesigned to accommodate the heavier engine, which is to take up to three-four years.^[30]
After evaluation and acceptance of the technical offer provided by both Eurojet and GE Aviation, the commercial quotes were compared in detail and GE Aviation was declared as the lowest bidder. The deal will cover purchase of 99 GE F414 engines. The initial batch will be supplied by GE and the remainder will be manufactured in India under a transfer of technology arrangement.^[

HAL TEJAS

Tejas
HAL Tejas
Role	Multirole fighter
National origin	India
Manufacturer	Hindustan Aeronautics Limited (HAL)
Designer	Aeronautical Development Agency
First flight	4 January 2001
Status	In production
Primary users	Indian Air Force Indian Navy
Number built	13 (prototypes and LSP aircraft)
Program cost	US$1.2 billion
	US$31.09 million (Naval version) The HAL Tejas (Hindi pronunciation:  is a multirole light fighter developed by India. It is a tailless, compound delta-wing design powered by a single engine. It came from the Light Combat Aircraft (LCA) programme, which began in the 1980s to replace India's ageing MiG-21 fighters. Later, the LCA was officially named "Tejas",meaning "Radiance" by then Prime Minister Atal Bihari Vajpayee. The Tejas has a pure delta wing configuration, with no tailplanes or foreplanes, and a single dorsal fin. It integrates technologies such as relaxed static stability, fly-by-wire flight control system, multi-mode radar, integrated digital avionics system, composite material structures, and a flat rated engine. The Tejas is the second supersonic fighter developed indigenously by Hindustan Aeronautics Limited after the HAL Marut. The Indian Air Force (IAF) is reported to have a requirement for 200 single-seat and 20 two-seat conversion trainers, while the Indian Navy may order up to 40 single-seaters to replace its Sea Harrier FRS.51 and Harrier T.60. The Tejas was cleared in January 2011 for use by Indian Air Force pilots. It is to reach the second of three levels of operational clearance in November 2013.

Engines of PAK FA

PAK FA compressor stall at MAKS-2011.

On its first flights, the PAK FA was expected to use a pair of conventional Saturn 117S engines, but a new engine 117 (AL-41F1) powered its first flight. The new engine features a digital control system (FADEC), and is reportedly capable of producing 33,000 lbs (147 kN) of thrust in afterburner, has a dry weight of 1420 kilogram and a thrust to weight ratio of 10.5:1.
According to Sukhoi director Mikhail Pogosyan, the 117 (AL-41F1) is a new fifth generation engine built specifically for the PAK-FA. Pogosyan has clarified that claims of the use of an older engine are incorrect. Though the specifics of the new engine remain classified, information provided has included: increased engine thrust by 2.5 tonnes over the AL-31 engine, a reduction in engine weight by 150 kilograms (330 lb). These changes allow the aircraft to supercruise, sustaining supersonic flight speeds without using afterburners. Mikhail Pogosyan further mentioned that this engine (117) meets the Russian Air Force's requirements and will be installed in production PAK-FA aircraft.
The engine generates a larger thrust and has a complex automation system, to facilitate flight modes such as maneuverability. It is expected that each engine will be able to independently vector its thrust upwards, downward or side to side. Vectoring one engine up with the other one down can produce a twisting force, which would enable the PAK FA to be the first fifth generation fighter with full 3-D thrust vectoring along all three aircraft axes: pitch, yaw and roll. These engines will incorporate infrared and RCS reduction measures.
There is little information about the new engine of T-50. According to preliminary facts, the engine will have increased thrust and fuel efficiency as compared to AL-41F1. Allegedly, the powerplant will have a thrust of about 107 kN in cruise mode and 176 kN in full afterburner mode.

Design of PAK FA

 

Prototype T-50 in flight

Although most information about the PAK FA is classified, sources within in the Russian Air Force and Defense Ministry have openly stated that it features stealth technology and has the capability to supercruise,and incorporate advanced avionics such as an Active Electronically Scanned Array (AESA) radar and an artificial intelligence system. It is to be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles.
Video from the PAK FA's first flight shows that it has no conventional rudders; its vertical tails are fully movable. This special tail fin design is mechanically similar to V-tails used by the Northrop YF-23 in 1990s, but is supplemented by dedicated horizontal stabilators (as on the F-22). The T-50 has wing leading-edge devices above the jet engine intakes that may pose a challenge for signature control.
Composites are used extensively on the T-50 and comprise 25% of its weight and almost 70% of the outer surface.It is estimated that titanium alloy content of the fuselage is 75%. Sukhoi's concern for minimizing radar cross-section (RCS) and drag is also shown by the provision of two tandem main weapons bays in the centre fuselage, between the engine nacelles. Each is estimated to be between 4.9-5.1 m long. The main bays are augmented by bulged, triangular-section bays at the wing root.
The Moskovsky Komsomolets reported that the T-50 has been designed to be more maneuverable than the F-22 Raptor, at the cost of making it less stealthy than the F-22. One of the design elements that have such an effect is the Leading Edge Vortex Controller (LEVCON).

Cockpit

Life support systems will enable pilots to sustain 9 g in maneuvers. New pressure suits will allow safe ejection at altitudes of up to 23 km.

Stealth

Russian sources indicate the PAK FA lacks the very-low-observable (VLO) stealth of the F-22. Instead, reducing observability with composite materials, aerodynamic configuration, and engine signature reduction measures to achieve low (but not very-low) levels of radar, optic and infrared signatures.Carlo Kopp has said that once the PAK FA is fully developed into a stealthy design, it should be a rough match for the F-35 in low observability, but aerodynamically superior.Sources claim that the PAK FA may incorporate "Plasma stealth" although no solid evidence of this has been shown.

Armament

The PAK FA has a reported maximum weapons load of 7,500 kg.It has an apparent provision for a cannon (most likely GSh-301), and could possibly carry two 30 mm cannons. The PAK FA has two internal bays estimated at 4.6-4.7 metres by 1-1.1 metres.The expected initial armaments include Kh-35UE (AS-20 "Kayak"), Kh-38ME, Kh-58UShKE (AS-11 "Kilter"), and RVV-MD (AA-11 "Archer") missiles.
Two Izdeliye 810 Extended beyond visual range missiles per weapons bay. Multiple Izdeliye 180 / K77M beyond visual range missiles. K74 and K30 within visual range missiles can also be carried. Two KH38M or KH58 USHK air-to-ground missiles per weapons bay. Multiple 250–500 kg precision guided bombs per weapons bay, with a maximum of 10 bombs in internal bays. Other possible loads include one 1,500 kg bomb per weapons bay or two 400 km+ range anti-AWACS weapons (such as the RVV-BD) on external hardpoints.
PAK FA chief designer Alexander Davydenko has said that there is a possibility of the installation of BrahMos supersonic missile on the PAK FA and its FGFA derivative. However, it is unclear how these missiles will be installed, though it can be one or two missiles only due to heavy weight of the BrahMos

Sixth generation planes

 

A sixth-generation jet fighter is a conceptualized class of fighter aircraft design more advanced than fifth-generation jet fighters which are currently in service in the United States of America and in development in other countries. The United States Air Force and United States Navy are anticipated to field their first sixth-generation fighters in the 2025–30 timeframe.
Design concepts
The under development Chinese Chengdu J-20, Indian HAL Advanced Medium Combat Aircraft and the Russian Sukhoi PAK FA are now providing more advanced fighters to compete with current American fifth generation jet fighters.
Dubbed the "Next Generation Tactical Aircraft"/"Next Gen TACAIR",the USAF seeks a fighter with "enhanced capabilities in areas such as reach, persistence, survivability, net-centricity, situational awareness, human-system integration and weapons effects," a November 4, 2010 presolicitation notice states. “The future system will have to counter adversaries equipped with next generation advanced electronic attack, sophisticated integrated air defence systems, passive detection, integrated self-protection, directed energy weapons, and cyber attack capabilities. It must be able to operate in the anti-access/area-denial environment that will exist in the 2030–50 timeframe.”
Lockheed Martin's Skunk Works division has revealed a conceptual next-generation fighter design that offers the first hints of an ambitious, long-term technology strategy for the new class of tactical aircraft that will emerge after 2030. The concept was published in a 2012 calendar, which was distributed to journalists. Lockheed Martin has called for greater speed, range, stealth and self-healing structures.
The equivalent in the United States Navy is the Next Generation Air Dominance program.
The Sixth Generation fighters are expected to use advanced engines such as Adaptive Versatile Engine Technology to allow longer ranges and higher performance.
USAF's General Mike Hostage has said that they have yet to decide on which features will define the sixth generation fighters.
In 2013 DARPA started a study to try to bridge the USAF and USN concepts.^[
