The Sukhoi Su-49 was a Russian trainer developed in the 1990s and 2000s. Development work ceased in late 2003, and no examples were built.
Development[edit]
Development of the aircraft started in July 1992 under the designation Su-32 to meet trainer requirements. The Su-26 and Su-29 were the basis of the trainer. Later, the designation changed to Su-39 in 1995, before finally being redesignated as Su-49 in 1996. Construction of a prototype began in 1994, and the aircraft was scheduled to perform its maiden flight in 1996. Design refinements in mid-1997 included: LERX, raised canopy, and twin nosewheels.[1]
The engine was supposed to be a Vedeneyev M-14PF engine, which produced 400 hp. However, the M-14PF's unreliability and short service life led to the M-14P (360 hp)[2] or the M9F (420 hp) that was installed on the Su-29KS.[3] Nonetheless, the designers considered the Pratt & Whitney Rus PK6A-25 turboprop engine to replace the M9F.[1]
In October 2001, the Su-49 won a competition against the Yakovlev Yak-152 as a Russian Air Force trainer, with the first flight, after some delays, planned to be in 2002, although insufficient funding led to Sukhoi abandoning the project.[1]
Design[edit]
The Su-49's cockpit has two seats in a tandem layout. GPS and long-range and short-range navigation systems can be fitted. An automatic approach system could also be installed. Both positions are equipped with the SKS-94M-49 ejection seat.[4] The Su-49 is supposed to provide navigation, night, all-weather, high-g, and weapon instructions.
The airframe is constructed using composite materials.[3] It can perform aerobatics at +11 / -10[4] or -8 g.[3]
