Transpiration Cooling Using Liquid Water

, 2007
At the Space Launcher System Analysis (SART) department of DLR-Cologne, a hypersonic spaceplane for passenger transportation is being investigated. A major challenge is the aerodynamic heating of the vehicle.

Characterisation of the USQ hypersonic facility freestream

, 2019
Hypersonic ground testing can make significant contributions to the design process for hypersonic flight vehicles. However, experimentation in conventional hypersonic ground testing facilities is complicated by the high levels of freestream fluctuations ...

Configuration development study of the OSU 1 hypersonic research vehicle

, 1993
In an effort to insure the future development of hypersonic cruise aircraft, the possible vehicle configurations were examined to develop a single-stage-to-orbit hypersonic research vehicle (HRV). Based on the needs of hypersonic research and development,

Shock-Wave-Boundary-Layer Interaction (SWBLI) around open Flaps of EXPERT Capsule and their Consideration on Heat and Mechanical Loads under critical Re-Entry Flow Conditions

, 2006
In the frame of EXPERT project DLR is proposing a flight experiment on shock-wave boundary-layer interaction (SWBLI) with shear-layer reattachment on control surfaces to improve our understanding about flap efficiency and heating due to high temperature ...

Orbital delivery of small payloads using hypersonic airbreathing propulsion

, 2006
Scramjet engines promise significantly higher specific impulse than rockets during the hypersonic phase of low earth orbit insertion trajectories. Despite this, scramjets are not used on any current systems, due to the difficulty of operating over the ...
