Figure 1-7 — the ramjet engine. Figure 1-8 — The Aeropulse or pulsejet. • Air compression depends solely on “ram effect." • A limited amount of heat is added. • Considerable heat is lost by radiation. The next step is to improve the method of adding heat, through internal combustion. Figure1-7 shows a divergent-convergent
The ramjet engine produces power by increasing the momentum of the working fluid, i.e. air. • In contrast to the other air-breathing engines, the working cycle is done without compressor and turbine, and also without any need for enclosed combustion. •Ramjet engine is mechanically the least complicated air-breathing jet
Design of a Ramjet. • Design of a ramjet engine and performance prediction involves estimation of pressures, temperatures, velocities and flow areas at the critical stations through the engine. • Even though various analytical CFD techniques, including those incorporating reactive flow, have now come into use, it is still
Ramjets - Basic Operating. Features. • Air decelerated in intake (diffuser) and pressure rises due to ram effect. • Known as ram pressure and significant at supersonic speeds. • A ramjet therefore needs neither a compressor nor a turbine, simplifying the design and reducing the cost. • Greatest disadvantage is that it has to be

Ramjet engine. To ram means to force in. In ramjet air is forced into the engine air intake by the sheer drive of the speed of flight. Ramjet, in principle, can work at subsonic the design regime. The usual tool for analysis of the processes in engines is the so-called enthalpy-entropy diagram. The thermodynamic state of air is
and design of subsonic and supersonic ramjet engines is based on domestic and foreign iraterials which have been published in the form of books and magazine ,articles. "The theory of the basic elements of the engine -- diffusers, tom.bustion chambers, and jet nozzles -- is considered, as well as the operation of the entire
