Abstract:

Ramjet engine thrust depends on the acceleration of a working fluid by the addition of heat. The most practical method of heat addition is by the combustion of fuel in air, and the most commonly used fuels are storable liquid hydrocarbons. However, the effectiveness of the ramjet cycle is not restricted to this mode of heat supply or to this class of fuel, and other possibilities are discussed. Criteria for selecting a fuel, methods of calculating flame temperatures and specific impulse parameters, and prospects for obtaining fuels with improved performance are outlined.
