ABSTRACT:
A dual mode semi-passive nosetip cooling system for a hypersonic weapon. A cone shaped capsule or pressure vessel is positioned within the nosetip and it is filled with a sublimating material in solid state. The capsule has a nozzle formed adjacent its forward end that directs a steady impingement stream of sublimation material to the back side of the nosetip shell in its stagnation region when the sublimating material is being heated by the surface heat on the nosetip itself. The concept is based on utilizing the advantages of both a subliminating and impingement cooling system designs.
