Combustion Limits and Efficiency of Turbojet Engines [PDF]
Combustion must be maintained in the turbojet-engine combustor over a wide range of operating conditions resulting from variations in required engine thrust, flight altitude, and flight speed. Furthermore, combustion must be efficient in order to provide

Evaluation of a bulk calorimeter and heat balance for determination of supersonic combustor efficiency [PDF]
Results are presented from the shakedown and evaluation test of a bulk calorimeter. The calorimeter is designed to quench the combustion at the exit of a direct-connect, hydrogen fueled, scramjet combustor model, and to provide the measurements necessary
