Rotary piston engine e.g. aircraft engine, has displacement combs that cross out a portion of revolution at rest, such that memory usage optimization of engine which works with small and average powers is established in the combs

摘要

The rotary piston engine consists of a compressor stage (5), a heat-resistant expansion stage (7), an expansion stage (46) and a combustion chamber (21). Each of the main rotor (11) and three secondary rotors (4) are set with sealing strips. The displacement combs are engaged with three profiled longitudinal grooves of main rotor. The displacement combs cross out a portion of revolution at rest, such that memory usage optimization of the engine which works with small and average powers using the water vapor intake flaps, is established in the displacement combs. The rotary piston engine consists of a compressor stage, a heat-resistant expansion stage, an expansion stage and a combustion chamber. Each of a main rotor and three secondary rotors are set with sealing strips. The displacement combs are engaged with three profiled longitudinal grooves of main rotor. The diameter ratio between side runners and main rotor, the gear ratio of outer tooth, and the speed of secondary runners to main rotor is set to preset value. The combustion chamber is arranged in the interior of main rotor and is firmly fixed to housing. The inlet pressure valve is arranged in the compressor stage. The internal tube is provided in the inner chambers (42) as the pressurized air storage. The connecting slats are arranged between the sealing strips and the counterweights are arranged in the displacement combs and on the tips of the longitudinal recesses. The displacement combs cross out a portion of revolution at rest, such that memory usage optimization of the engine which works with small and average powers using the water vapor intake flaps, is established in the displacement combs.
