Quasi Area Rule for Heat Addition in Transonic and Supersonic Flight Regimes

Abstract

Body shapes, including axisymmetric and three dimensional, have been developed to minimize wave drag. The von Karman ogive and the area rule are examples. Similar work has not been accomplished for optimum shapes with propulsion. Propulsion can be divided into two categories--those devices with internal heat addition and those with external burning. For internal heat addition an analytical model is formulated which introduces the propulsive disc. Attention is shifted to external burning, which is examined for one dimensional and two dimensional linearized flow. Heat fronts and combustion fans are discussed as examples. Forces on a heat source in a uniform stream and adjacent to bodies are derived.
