Analysis of low-thrust liquid rocket engines with a methane air pump unit
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016 The first airplane working on cryogenic fuel was developed in the USSR in early 1980s on the basis of the passenger aircraft Tu-154. It was then modified using a hydrogen engine installed instead of one of the three kerosene engines.
