Sustained Hypersonic Cruise Flight

05.01.2012

Hypersonic cruise demands designs achievable only via multidisciplinary optimization techniques considering fully integrated propulsion systems. Additionally, environmental issues and thermal problems may require solutions using non-conventional flow-control techniques based on e.g. jet-spikes and magneto gas dynamics.
