Мое почтение!

Из Джейнс Aero Engines 22-11-01:

This engine replaced a joint effort with Pratt & Whitney designated PS-90P. It was designed to replace the PS-90A on the Il-96-300 and the PW2337 on the IL-96M/T. It is interchangeable with the PS-90A, but is upgraded in the following items: from USA, improved HP turbine and bearing support (Pratt & Whitney), FADEC control system (Hamilton Standard), pneumatic valves (AlliedSignal) and oil filters (Pall); from France, optical pyrometer (Auxitrol) and electrical connector (Deutsch); from Germany, on-board monitoring system (BGT), fuel/oil heat exchanger (Behr) and bearings (FAG); from Sweden, bearings (SKF), and from Russia, design refinement and certification (AVI) and production (PECo [Perm Engine Co]). Its description differs from the basic PS-90A in the following:

Fan

Mass flow 500 kg (1,102 lb)/s. Pressure ratio 1.746. Bypass ratio 4.29.

HP Compressor

Overall pressure ratio 35.2.

HP Turbine

Entry gas temperature 1,750 K (1,477єC).

LP Turbine

Max gas temperature 933 K (660єC).

Control System

FADEC.


Specific Fuel Consumption


Cruise (11,000 m, 36,090 ft, M0.8)
16.99 mg/Ns (0.600 lb/h/lb)

ПС-90П


ПС-90А2

Здравствуйте.

А есть ли у Вас уверенность, что приведённый текст именно об ПС-90А2, а не о ПС-90P (или ПС-90П?)?
