Cryoplane: a Russian-German cooperative venture. Cryogen fueled aircraft.

Type of article: Periodical article

Summary

Between 1990-92 German and Russian firms have cooperated in investigating cryogenic fuels for aircraft propulsion (liquid hydrogen and LNG). Because LNG is itself a fossil fuel, work has concentrated on liquid hydrogen. The Russian research aircraft Tu-155 has already tested both fuels. Both fuels have a higher energy to mass ratio than kerosene. LNG does not eliminate CO2 emissions, liquid hydrogen does, and might be generated by electrolysis using renewable energy, but due to high volume requires four times the kerosene tank capacity. These pressurized liquid hydrogen tanks would need to be circular and would best be accomodated at the top of the fuselage. Water vapour is a greenhouse gas but the effect at normal cruising altitude is less than CO2 from kerosene. D.W.H.
