2011 Paris Air Show: ZEHST, the hypersonic aircraft by EADS (VIDEO)
Here is the ZEHST, a project of hypersonic plane that runs on biofuel and hydrogen.
Designed by EADS, in cooperation with Japan, as part of a program funded by the Directorate General of Civil Aviation of both countries (military applications such as UAV’s are also considered), it relies on three existing engines, each corresponding to a flight phase.
Phase 1 take off and up to 5000 meters
Standard reactors (2 turbojets) operating with a fuel based on seaweed (biofuels 3.0) allow to reach Mach 0.8
Phase 2, up to 23000 meters
Cryogenic engines fueled with hydrogen (3 rocket engines), take over.
Phase 3 Stratosphere and up to 32,000 meters
At this altitude, conventional fuels are not a threat for our atmosphere anymore, the Zehst can then reach Mach 4 thanks to 2 Ramjets.
Is it for 2050?
No, the first flights are announced for 2021, capacity 50 to 100 passengers, estimated flight times in Tokyo Paris or Los Angeles, 2h30...
