Sukhoi Company adds to flight tests program the second PAK FA prototype
03 Mar 2011
Moscow, March 3. Today the first flight of the 2nd prototype of the fifth generation aviation complex (PAK FA) took place in Komsomolsk - on - Amur. The plane was piloted by distinguished test pilot of the Russian Federation Sergey Bogdan. The aircraft spent in the air 44 minutes and landed on the factory airfield runway. The flight was successful, in full accordance with the flight plan. Stability of the aircraft test was conducted during the flight as well as evaluation of the power plant systems’ performance. The aircraft proved itself well in all phases of the planned flight program.
Tests on the PAK FA program are in accordance with the approved program. Currently, a set of preliminary ground and flight operations has been completed involving all three prototypes, which underwent bench strength tests, ground tests of fuel systems and other work.
The first flight of the PAK FA took place on January 29, 2010 in Komsomolsk-on-Amur. Acceptance tests of the prototype were completed at the end of March 2010. On April 8, 2010 the first flight model of the fighter jet and a comprehensive ground stand for working out the equipment and systems to provide flight test program, were delivered to the flying test center of the Sukhoi Design Bureau in Zhukovsky near Moscow. Upon completion of the required volume of preliminary tests on the stands of systems and components, including static strength tests of the static prototype, ground tests of the aircraft stand and the flight model, on April 29, 2010 the aircraft had started flight tests in accordance with the preliminary tests program. The first flight model made 36 sorties in accordance with the flight tests program.
Compared to the previous generation fighters, the PAK FA features a number of unique capabilities, including the functions of a strike aircraft and fighter. The 5th generation aircraft is fitted with essentially new avionics integrating the function of “an electronic pilot” and with an advanced phased antenna array radar. This considerably reduces the pilot fatigue, enabling him to concentrate on performance of a tactical mission. The new aircraft’s onboard equipment makes it possible to exchange information in the real time mode both with on-land control stations and with aviation group aircraft. The use of composite materials and innovative technologies, and the aerodynamic streamlining ensure unprecedented radar, optic and infrared stealthiness. This significantly enhances the operational capability against aerial and ground targets in all weathers, day and night.
