ABSTRACT:
Flame holder apparatus and method of operating same for a burner in a high velocity gas stream of an air-breathing jet engine. A flame holder body of aerodynamically streamlined external configuration is provided which extends spanwise across a high velocity gas stream of the engine. Fuel and air for the burner is supplied by way of a mixing chamber arranged internally of the flame holder body in such a manner that a homogeneous mixture, including all of the fuel necessary for combustion, is provided by way of the flame holder body so that separate fuel injection nozzles become unnecessary. Various preferred embodiments of the invention include arrangements of the flame holder apparatus in the bypass air stream and downstream of the combustion chamber.
