Hypersonic Pitching Control Model Development

, 2018
Test of actuated surfaces is currently being performed in a hypersonic wind tunnel for the development of practical control methods for hypersonic vehicles. Hinged flapping plate models with on board electronics for actuation and data-logging were placed

Investigation of Stability and Control Shortcomings of the North American X-15

Aerospace
There is growing interest in the design of maneuvering high-speed aircraft to fly within or at the edge of the atmosphere. We identify and develop novel quasi-static vehicle screening methodologies, suitable for use during preliminary design, to better ...

Hypersonic wind-tunnel free-flying experiments with onboard instrumentation

, 2015
Hypersonic wind-tunnel testing with "free-flight" models unconnected to a sting ensures that sting/wake flow interactions do not compromise aerodynamic coefficient measurements. The development of miniaturized electronics has allowed the demonstration of
