Lifting Bodies Derived from Supersonic Flows Past Inclined Circular and Elliptic Cones.

摘要

Lifting-body configurations are constructed from stream surfaces generated by means of supersonic flows past inclined circular and elliptic cones. By such means waverider shapes are devised with curved surfaces and known pressure fields and shock-layer structures. The conical flow fields stem from perturbations of the basic axisymmetric cone flow arising from small angle of attack and small cross-section eccentricity. The approximate results are analytic and in the form of hypersonic small disturbance theory. Various possibilities for waverider shapes are discussed. Design formulas are presented that determine how the Mach number, angle of attack, cross-section eccentricity, and characteristic cone angle affect the waverider shape, pressure distribution, and shock-layer structure.
