A brief survey of experiments on aerodynamic flame stablization is given. A region within a combustion chamber is produced by secondary air jets directed obliquely towards the main flow in which a flame can burn permanently. The described investigations on model combustion chambers lead to statements on an appropriate design and arrangement of the stabilization devices and additionally give information on the behaviour of the main flow disturbed by the secondary jets. Further in a theoretical investigation the application of the aerodynamic flame stabilization in the secondary flow of a turbofan engine is studied. Characteristic data are defined which make possible a comparison with the mechanical flame stabilization used so far.
