Abstract:

Transition, laminar flow separation and aerodynamic error band are some aerodynamic issues which should be paid more attention to for hypersonic flight. The aerodynamic properties may be influenced obviously and with some uncertainty by transition and laminar flow separation. And how to determine the aerodynamic error band reasonably is also a key for hypersonic flight. These issues and their influences are discussed in this paper mainly from the view point of engineering design. To fulfill the need of hypersonic flight, we should further develop the relevant theoretical analysis and digital simulation technology and raise the technical level of ground tests at wind tunnel. Besides, aerodynamic flight tests should also be emphasized.

Key words: hypersonic, aerodynamic design, transition, flow separation, aerodynamic error band
