Steady and Unsteady Supersonic Flow Control with Energy Addition Conference Paper uri icon

abstract

  • This paper presents a review of some experimental and theoretical results obtained by the authors and their collaborators during the past few years, including:The effect of a plasma (directed-energy) air spike in supersonic/hypersonic flows. The similarity laws for shock wave and drag parameters, as functions of the strength of heat source and characteristics of incident flow, and experimental and computational parametric studies are discussed.Modeling of "virtual cowl," i.e., of energy addition to hypersonic flow off the vehicle in order to increase air mass capture and reduce spillage in scramjet inlets at Mach numbers below the design value.Numerical studies of aerodynamic forces created by off-axis heat addition upstream of a body. These forces and moments can be used for supersonic/hypersonic vehicle steering.Experiments and numerical modeling of pulsed off-body energy addition for sonic boom mitigation. © 2003 by authors.Published by the American Institute of Aeronautics and Astronautics, Inc.
