NOVEL TECHNIQUE FOR HYPERSONIC DRAG CONTROL USING HEAT ADDITION IN THE SHOCK LAYER

摘要

It is an object of this invention to develop a novel passive flow control technique for bodies in hypersonic flight wherein the shock layer around the bodies in flight at hypersonic Mach numbers is modified in-flight, by controlling the amount of heat energy released into the shock layer of the body, consequently controlling the aerodynamic drag. In the present invention the aerodynamic drag of the bodies in flight are controlled using non-intrusive passive devices that require no additional power. Further, suitable material coatings are developed for bodies in flight at hypersonic Mach numbers for controlled heat release into the shock layer during flight.
