Samara/Trud has been
working since about
1968
on the use of LH2/LNG (liquid hydrogen and liquefied natural gas) for various gas-turbine engines. A
particularly important development programme was the conversion of an NK-8-2
engine to burn either of the two new liquids, and of the tankage, piping and control system of a
Tu-154 to accept such an engine. The result was the
Tu-155 aircraft, which on 15 April
1988
became the first jet aircraft to fly with an engine burning liquid hydrogen. This was fed to the
modified engine, designated as NK-88, installed in the right-hand (not centre) position. After
12 flights the aircraft was converted to feed LNG to the test engine, thereafter flying to Nice, Hanover
and Berlin.
Kuznetsov
Engine Design Bureau would like to test these fuels on an A310 with JT9D engines, followed by PW4000s.
All this work is directed towards the NK-89, intended to power all versions of
Tu-156.
