hypersonic range
1.The method of wing shape optimization of space shutlle has been developed with penalty function approach in which the objective function is the mass of the wing and the constraints are the hypersonic re-entry flight cross range, lift/drag ratio, and subsonic flight lift/drag ratio, the margin of the longitudial static stability and the magnitude of the horizontal landing speed etc.
2.Norris, an intrepid entrepreneur who has no college degree but more than 43 patents to his name, invented both the crowd control tool, called the Long Range Acoustical Device (LRAD), and the display audio technology, called HyperSonic Sound (HSS).
