The third and fourth references are the detailed description of the computational technique behind the computer program. Harris, Roy V.,Jr.: An Analysis and Correlation of Aircraft Wave Drag. NASA Technical Memorandum X-947, March 1964. WebJan 20, 2005 · The main difference when compared to incompressible thin airfoil theory is the appearance of drag (in an inviscid flow). The source of this drag is theradiationto infinity of pressure waves created by disturbances at the surface of the airfoil. We will call this dragwave drag. 3 AA200b - Applied Aerodynamics II Lecture 5
In aerodynamics, aerodynamic drag (also known as air resistance) is the fluid drag force that acts on any moving solid body in the direction of the air freestream flow. From the body's perspective (near-field approach), the drag results from forces due to pressure distributions over the body surface, symbolized , and forces due to skin friction, which is a result of viscosity, denot… WebApr 22, 2014 · The wave drag is an important factor that affects the supersonic flight efficiency and is closely related to the aircraft’s cross-sectional area distribution. A …
WebTo see how the lift and drag of a thin body in a supersonic stream can be estimated, consider a flat plate inclined at a small angle α to a horizontal stream (Figure 15.27). At … WebIn supersonic flow regimes, wave drag is commonly separated into two components, supersonic lift-dependent wave drag and supersonic volume-dependent wave drag. The closed form solution for the minimum wave drag of a body of revolution with a fixed length was found by Sears and Haack, and is known as the Sears-Haack Distribution .
WebThe shock wave from a supersonic object is a cone composed of overlapping spherical wavefronts. As any one of these wavefronts forms, it propagates radially outward at speed c and acquires a radius ct. At the same time the source, traveling at speed v moves forward vt.
