摘要： The aim of the present invention is to provide a separate-type rotary engine which significantly reduces vibrations and weight as compared to conventional cylinder-type internal combustion engines, which is simple in configuration and thus reduces manufacturing costs, which directly generates rotary force rather than through a crankshaft to increase mechanical efficiency, and in which a compressor and a force generator are separated from each other to enable the simple design of an engine suitable for a variety of uses. The engine of the present invention shown in FIG. 1 comprises: said compressor and force generator including housings (1 and 1'), each of which has a circular inner cross-sectional surface; rotors (3 and 3'), each of which has a circular or elliptical shape or a combination of a circular and elliptical shape, and rotates with one side thereof contacting the housing and the other side thereof spaced apart from the housing using the center of the circular inner space of the housing as an axis; and hinged vanes (9 and 9'), each of which has one end hinged to an upper portion of each of the housing (1 and 1') and the other end contacting each of outer surfaces (4 and 4') of the rotating rotors (3 and 3') to prevent a drop in the pressure of the compressed air and combustion gas during compression and expansion. The thus-configured compressor and the force generator are further provided with a compressed air tank (12) interposed between a one-way check valve (11) and a compressed air valve (13) to store high-pressure compressed air, wherein the open/shut operation of the compressed air valve (13) is controlled in accordance with the rotation position of the rotor (3') of the force generator, so as to store high-pressure compressed air; a fuel nozzle (15) for injecting fuel into the compressed air discharged at a high speed from the compressed air tank (12); an ignition device (16) for burning fuel in a combustion chamber (7); a gas exhaust port (18) formed at an end of an exhaust space (6-4) to discharge combustion gas to the outside of the engine; and an air intake port (17) formed at a front end of an air intake space (6-1) of the compressor to serve as a passage for introducing air from the outside of the compressor. The engine of the present invention is advantageous in that one combustion is performed per one rotation of each of the rotors, each of the rotors is located dead center in each of the housings rather than being eccentric, the expansion stroke of combustion gas is significantly longer to reduce vibrations and to improve engine efficiency as compared to a rotary engine (Wankel engine), and the compressor and the force generator are arranged independently from each other on a same rotary axis to enable easy changes in the sizes thereof and the simple design of an engine suitable for a variety of purposes.

摘要： A compound cycle engine system (10) has a rotary engine (24), which rotary engine generates exhaust gas.
The system further has a compressor (16) for increasing the pressure of inlet air to be supplied to the engine to a pressure in the range of from 3.0 to 5.0 atmospheres and an intercooler (22) for providing the inlet air to the engine at a temperature in the range of from 150 to 250 degrees Fahrenheit. The system further has one or more turbines (18, 26) for extracting energy from the exhaust gas. The Miller Cycle is implemented in the rotary engine, enabling the compression ratio to be lower than the expansion ratio, allowing the overall cycle to be optimized for lowest weight and specific fuel consumption.摘要翻译： 复合循环发动机系统（10）具有旋转发动机（24），该旋转发动机产生废气。 该系统还具有用于将供给发动机的入口空气的压力提高到3.0-5.0大气压的压缩机（16），以及用于将空气供给到发动机的入口空气的中间冷却器（22） 温度范围为150至250华氏度。 该系统还具有用于从废气中提取能量的一个或多个涡轮机（18,26）。 在旋转发动机中实现了米勒循环，使压缩比低于膨胀比，从而可以优化整体循环，以获得最低的重量和特定的燃油消耗。
