Analytical Investigation of External Burning behind Bluff-Base Axisymmetric Bodies

Abstract

The final results and academic achievements are reported on a program aimed at investigation of external burning propulsion. Concentration was aimed at bluff-base, axisymmetric bodies in supersonic flight with an approach boundary layer that is fully turbulent. An adiabatic near wake theory was developed which is in excellent agreement with experiment. A parametric investigation of external burning performance showed that while high thrust levels can be achieved the specific impulse is lower than expected. Consequently, future studies should concentrate upon a combination of base burning and external burning.
