Kuznetsov NK-89

The NK-89 was a modified version of the hydrogen-powered NK-88[1] and was designed to run on both liquified natural gas[2] (LNG) and kerosene.[2] This aircraft was to have cryogenic tanks in the rear of the cabin and forward baggage hold to store the LNG.[2] In January 1989, a test flight of a prototype of this engine was carried out onboard of the Tupolev Tu-155 flying laboratory where LNG was used as fuel.[2] The switch from LNG to kerosene could be made in-flight in 5 seconds.[2] Data from Otechestvennaya aviatsionno-kosmicheskaya tekhnika - SAMARSKIY NTK[1] and janes.migavia.com[2] Comparable engines Related lists
