Control (Delay or Accelerate) Hypersonic Boundary-Layer Transition

This invention is novel flow control techniques for modifying the natural to turbulent transition process of the flow in the boundary layer of vehicles, projectiles, or missiles at supersonic/hypersonic speeds. This invention is concerned with delaying the onset of transition and the subsequent breakdown to turbulence as far downstream on the vehicle...

Control of Boundary-Layer Transition for Hypersonic Flight

This invention provides techniques to control the nonlinear phase transition of laminar-turbulent flow in hypersonic boundary layers while reducing negative effects on the vehicle while in the transition region. Background: Generally, there is a large amount of friction and heat transfer during transition, which can compromise multiple aspects of...
