The Sukhoi PAK FA T-50 is a multi-role stealth fighter aircraft being developed by Sukhoi of Russia and is expected to cost around $50 million per aircraft.
The PAK FA boasts a number of unique features as compared with previous-generation fighters, and combines the functions of a strike aircraft and a fighter. This fifth-generation airplane, currently undergoing flight trials, is equipped with an entirely new set of deeply-integrated avionics featuring a high level of controlled automation and intelligent crew support. This considerably reduces the pilot’s workload and allows the pilot to concentrate on tactics. The avionics of the new airplane enable real-time data exchange with both ground-based control systems and within air groups, and also support off-line operation.
Aircraft specification are classified, but we did pull some specs from the Russian site militaryrussia.ru and translated it via Google translator.
Modifications: I-21 Sukhoi Design Bureau (2001) – a promising fighter razarabatyvavshisya under the program PAK FA-21. It was assumed that the aircraft will have a mass of about 20 tons, the flight range of up to 4000 km, supersonic cruising speed, low ESR area, maneuverability, it was supposed to provide shorter takeoff and landing. The aircraft proposed to use as a long-range interceptor and multipurpose fighter. Test aircraft was supposed to hold up to 2010, followed by the launch of a series and adoption of the Russian Air Force. T-50-0 / 50-T-PAC (rolled out in June 2009, previously it was thought that the first prototype was ready in December 2008 . – not confirmed) – the name of the “T-50-PAC” conditional – structurally-similar pattern – a variant of the aircraft T-50 for surface strength tests. Assembling such a series of structurally-samples T-50 was conducted at KPO KnAAPO with November 2006 Produced until December 2008, is likely two T-50 KME, but confirmed the existence of only one instance. T-50-0 – a body with strain gauges and vibration sensors, designed for static tests. It arrived in Suhogo (Moscow) in the spring and summer of 2009 (most likely after June 1, 2009), and passes the test there (first shown to the media March 1, 2010).
A single information system deployment and management. With the subsystem for data exchange with other aircraft. At least two multi-board computer connected to an optical interface Fibre Channel (probable capacity of up to 1 gigabit?). The system should provide interaction and information exchange with the command post, aircraft groups, intelligence systems Forces, Navy and Air Force. Provision collective action to squadrons of aircraft with automated data exchange.
The complex radar T-50 includes six integrated detection purposes:
1) Nasal radar AFAR W-121 X-band
2) Airborne radar AFAR X-band (to be placed in the forward fuselage)
3) Wing AESA radar with L-band
4) May feed AESA radar X-band
5) Container radar AFAR Ka-band (millisetrovy)
6) AFAR radar sensors distributed on the casing
7) Helmet-mounted target designation system.
The cockpit with color LCD-display and ergonomic controls. Testing is carried out in the cockpit Sukhoi on the full-scale cabin layout with a full range of cabin avionics T-50-1 (with the exception of the control and recording equipment).
The navigation system includes gimballess inertial navigation system SINS-SP-2 or and its modification – BINS-SP-2M and GPS / GLONASS navigation unit (three modes – GPS GLONASS, combined, feature – GLONASS more precisely, but not always work because of the small number of satellites). Development and production of systems BINS conducted OAO “Moscow Institute of Electromechanics and Automation.” In 2011, OAO MIEA made one prototype SINS-SP-2M for developing software for laboratory tests (OED), also made a prototype SINS-SP-2M for PI and manufactured prototypes of SINS-SP-2 for flight test T-50-3 (2 systems) and for flight tests of T-50-4 (2 systems).
The aircraft is equipped with electric remote control system (FBWCS) with digital control. T-50 has a dvuhkupolny brake parachute and in-flight refueling.
Sukhoi T-50 PAK FA Stealth Technology:
Engines: In the process of developing a flying laboratory tested for T-10M-10 board №710 (installed on the right, 1 piece) turbofans with digital control system and thrust vector control “article 117” / AL-41F-1. Developed by NPO “Saturn” (Rybinsk).
Weight – 15% less than that of the base AL-41F
specific thrust – 10 kg / kg
The engine is designed “Saturn” (Rybinsk) on the basis of the AL-41F engine on competition for the PAK FA (theme “Demon”, summed up the summer of 2003). Engine test completed in December 2006. Air Force Commander V. Mikhailov in December 2006, the engine is called an intermediate model with increased power and TBO. Serial production engine for the production of T-50 to be deployed in 2015-2016. On the engine uses a new low-pressure compressor with increased air flow and efficiency, the new turbine high reliability with improved blade cooling and engine management system with integrated digital controller integrated into the system of control of the aircraft.
2) Prospective engines for the T-50 (assumed to serial production not earlier than 2020): – promising engine serial T-50 version 1 – 2 x TRDDD (in the media and engine called “article 127” and “product 129”) with thrust vector control with traction on 17500-19500 kg (afterburner) and 11,000 kg (Maximal). Company “Salute”, “Saturn” and STC im.Lyulki zavepshili the second phase of the advanced engine for T-50 / PAK FA (17.06.2013, at the source ).
Specific thrust – perhaps 11.5-12.5 kg / kg
– Promising engine serial T-50 promising option 3 – 2 x TRDDD with thrust vector control specific thrust – 11.5-12.5 kg / kg
One 30 mm aircraft gun right in the fuselage. Some media pointed out that in the 2 arms of 30 mm caliber gun.
Russia’s United Aircraft Corporation Publishes Footage of Russian 5th Generation Fighter Cannon Tests:
16 suspension points including 8 in the inner compartments (media) – by dr.informatsii media – 10 suspension points in the inner compartments:
– two internal fuselage (approx. 5.1 m each) compartment
– Two center-internal compartment (on the prototype T-50-1 is probably missing or not mounted as of 29.01.2010) – The alleged.
– two compartment under the wing of conformal 1-2 short-range missiles each AA (1 compartment on the wing)
– 4 suspension assembly under the wing;
– 2 suspension assembly under the fuselage (under intake passage)
Armament of “air-to-air”:
– short-range missiles of a new type (including the housing square in cross-section) with IR homing (planned to adopt to 2014) – up to 12 units on the inner suspension.
– KS 172 or RVV-BD – 2 pieces on the external load, possibly up to 4 pieces (?)
– P-77 and derivatives thereof (“product 180” and others.) Armament class “air-surface”: – RCC – UAB
According to the corporation “Tactical Missiles” in the inner compartment of the aircraft can be placed missiles “air-to-air” and “air-to-surface” design bureau-structural components of the corporation.
“The air-to-air” – small missiles and long-range, as well as up to 4 medium-range missile development bureau “Vympel”. Missiles “air-to-air” design bureau “Innovator” in the arms of an airplane will not go.
“The air-to-surface” – RCC, SD and ASD caliber 250 lbs.
on the external load can carry missiles and bombs caliber up to 1500 kg
For the suspension arms to the compartments and on the point of suspension of T-50 is supposed to create a bootable mobile robotic feeder cargo (by “Universal”).
