具有一系列激波凸起的空气动力结构
摘要：
一种空气动力结构(1)，包括从其表面延伸的一系列激波凸起(3a，3b，3c)。激波凸起沿着一条线(7)布置，该线的平均掠角比非扰动激波(4)的平均掠角小，所述非扰动激波是指在所述结构没有所述激波凸起的情况下、在所述结构的跨音速运动过程中接近所述表面形成的激波。激波凸起沿着掠角比非扰动激波的平均掠角小的线布置，而不是沿着非扰动激波的线布置。当该结构以跨音速运动时，在其表面附近形成激波，激波凸起使该激波(9)扰动，以减小其掠角。
摘要（英）：

An aerodynamic structure (1) comprising a series of shock bumps (3a, 3b, 3c) extending from its surface. The shock bumps are distributed along a line (7) with a smaller mean angle of sweep than an unperturbed shock (4) which would form adjacent to the surface during transonic movement of the structure in the absence of the shock bumps. Instead of being distributed along the line of the unperturbed shock, the shock bumps are distributed along a line which is less swept than the mean angle of sweep of the unperturbed shock. When the structure is moved at a transonic speed; a shock forms adjacent to its surface and the shock bumps perturb the shock (9) so as to reduce its angle of sweep.
