HISTORY
The Sukhoi PAK FA is a fifth generation fighter aircraft being developed by Sukhoi OKB for the Russian Air Force. The PAK FA when fully developed is intended to replace the MiG-29 Fulcrum and SU-27 Flanker in the Russian inventory and serve as the basis of the Sukhoi/HAL FGFA project (being developed with India). As a 5th generation jet fighter, it is designed to directly compete with the American F-22 Raptor and American/British F-35 Lightning II.
The current prototype, called T-50, performed it's first flight on 29th of January 2010. It was flown by Sukhoi test-pilot Sergey Bogdan and lasted for 47 minutes. It's second flight took place on 6th of February. As of August 2010, it had made 17 flights and by mid November 2010, 40 in total.
In the late 1980s, the Soviet Union outlined the need for a next-generation aircraft to replace the MiG-29 and Su-27 in frontline service. Two projects were proposed to meet this need, the Sukhoi SU-47 and the Mikoyan Project 1.44. In 2002, Sukhoi was chosen to lead the design for the new combat aircraft. The PAK-FA will incorporate technology from both the Su-47 and the MiG 1.44.
Cockpit
The advanced aircraft features a single-seat cockpit equipped with number of electronic systems including automatic flight control systems (AFCS) and other auxiliary equipment.
Armament
Armament incorporated on the Sukhoi PAK FA aircraft includes two 30mm internal cannon Gsh-30-1 guns and eight R-77 missiles. The aircraft features eight hard-points (four on each wing) on which the missiles are mounted.
PAK FA radars
The radars of the PAK FA aircraft have been designed based on the Su-35BM’s systems.
Tikhomirov NIIP institute of instrument design bureau has incorporated N035 Irbis radar in the aircraft. The T-50 prototype is also equipped with an active antenna system and three X-band radars (forward and side-looking), ventral Ku-band radar encompassing identification friend or foe (IFF), actively electronic scanned array radar (AESA) and electronic warfare subsystems.
T-50 performance
The T-50 can climb at the rate of 350m/s. The maximum and cruise speed of the aircraft are 2,600km/h and 1,800km/h respectively. The range of the aircraft varies between 4,000km and 5,500km, and its service ceiling is 20,000m. The maximum endurance of the T-50 is three hours. The aircraft weighs around 18,500kg and has a maximum take-off weight of 37,000kg. The aircraft can hit targets within a 400km range.
