OPTIMAL PARAMETERS AND EFFICIENCY OF GAS-WATER JET ENGINES OPERATING ON "COLD" OR "HOT" GAS

The theory of an ideal gas-water jet engine is presented and the basic relations are derived. The maximum attainable load factor of the engine, the phase slip, the available gas energy in the nozzle are defined and an estimate is made of the attainable propulsion efficiency, taking into account the internal losses in the case of cold gas. The relationships for the hot gas arrangement (volumetric concentration of gas, compression ratio, load factor, velocity parameter) are treated without considering the additional losses due to cooling in the chamber and nozzle and are used to derive limit estimates. Graphical comparison of the attainable efficiencies permits an assessment of favorable conditions for using gas-water jets.
