초록

An apparatus and method of stabilizing unstable shock waves on the surface of a body induce shock waves to form prematurely at a particular location on a surface of the body and fix that location such that shock waves will form consistently and persistently at that location on the surface of the body. Boundary layer flow separates from the surface of the body at that location and can be prevented from reattaching to the surface. Shock wave oscillations due to interactions with the separated boundary layer flow are prevented, thereby minimizing vibrations...

청구항

An apparatus for stabilizing a location where a shock wave forms on a surface of a body moving in a fluid, the fluid having a boundary layer of flow adjacent to said body surface, comprising: means for accelerating fluid flow to a speed such that a shock wave is formed prematurely above said surface of said body; and a discontinuity in said means for accelerating for fixing the location where said shock wave forms and for fixing a point where said boundary layer of flow separates from said body surface, wherein said means for accelerating comprises a pro...
