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.

The Tupolev Tu-155 is a modified Tupolev Tu-154 (СССР-85035) which was used as an alternative fuel testbed, and was the world's first experimental aircraft operating on hydrogen and later liquid natural gas. The similar Tu-156 was never built.
The Soloviev D-30 is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet". It is probably the single most important turbofan engine developed in the Soviet Union. Development of the turbofan spurred numerous growth versions with increased fan diameter and modified component arrangements. Developed within an amazingly short period of time, the D-30 turned out to be one of the most reliable engines in the history of Soviet engine development, and it was recognized with the USSR State Prize.
The Kuznetsov Design Bureau was a Russian design bureau for aircraft engines, administrated in Soviet times by Nikolai Dmitriyevich Kuznetsov. It was also known as (G)NPO Trud and Kuybyshev Engine Design Bureau (KKBM).
The Kuznetsov NK-12 is a Soviet turboprop engine of the 1950s, designed by the Kuznetsov design bureau. The NK-12 drives two large four-bladed contra-rotating propellers, 5.6 m (18 ft) diameter (NK-12MA), and 6.2 m (20 ft) diameter (NK-12MV). It is the most powerful turboprop engine to enter service.
The Tupolev Tu-244 was a proposed supersonic transport (SST) aircraft, developed from the Tu-144. It implemented novel features such as cryogenic fuel to enable flight distances of up to 10,000 km (6,200 mi) and would have carried up to 300 passengers. The project was cancelled in 1993.
The Kuznetsov NK-32 is an afterburning three-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144LL supersonic transport. It produces 245 kN (55,000 lbf) of thrust in afterburner.
The NK-8 was a low-bypass turbofan engine built by the Kuznetsov Design Bureau, in the 90 kN (20,000 lbf) thrust class. It powered production models of the Ilyushin Il-62 and the Tupolev Tu-154A and B models.
The Kuznetsov NK-86 is a low bypass turbofan engine used on the Ilyushin Il-86 rated at 13,000 kgf or 28,600 lbf thrust. It is made by the Soviet Kuznetsov Design Bureau. It is an upgraded version of the Kuznetsov NK-8.
The Kuznetsov NK-144 is an afterburning turbofan engine made by the Soviet Kuznetsov Design Bureau. Used on the early models of the Tupolev Tu-144 supersonic aircraft, it was very inefficient and was replaced with the Kolesov RD-36-51 turbojet engine.
