The Kuznetsov NK-88 was an experimental alternative fuel turbofan engine, designed by the Kuznetsov Design Bureau.
Development of the NK-88 began in 1974[1] at the Kuznetsov Design Bureau. It was a modification of the NK-8-2U two-spool low-bypass turbofan[1] and was designed to run on liquid hydrogen (LH2).[1] A further development of this engine, the NK-89, was designed to run on both liquified natural gas[2] (LNG) and kerosine.[2]
On April 15, 1988,[1] one NK-88 running on cryogenically stored LH2[2] was tested in flight in the starboard nacelle of the Tupolev Tu-155 flying laboratory.[1] The other two nacelles contained engines of the native NK-8-2 type and ran on kerosene.
