Aerogasdynamics of Waveriders with Powder-Law Compression Surfaces
Abstract
Use of the well-known flows streamlines with specified properties to design spatial lifting configurations (waveriders) allows to simplify essentially an analysis of such form characteristics in the so-called design flow regimes which corresponds to their construction conditions. Waveriders using as the basis of a future hypersonic aircraft is widely discussed. Waveriders characteristics in the design regimes have been analyzed in a number of works. However, the off-design regimes applying to a hypersonic aircraft should be investigated. The investigations of such types are more limited, and for some classes of the waveriders they are absent at all. Hereinafter, the investigations results of the waveriders designed using the flows behind planar shock waves as basic flows are presented. A body surface is described by a power-law functions that allow to obtain a series of configurations with different cross-section shapes, including as a particular case, a widely known Nonweiler caret wing. Estimations of lift-to-drag ratio and integral heat fluxes to the surface in the design regimes are presented, and in the frames of the Euler equations the flow in the off-design regimes is numerically studied. It were considered flow patterns at both smaller and larger free-stream flow Mach numbers M of some design Md, at which the configuration was constructed.
