Research On The Design Scheme Of Micro Rotary Engine

Research of micro rotary engine is closely related to the progress of micro-electro-mechanical system. By reference to O.S. Graupner 49-PI model airplane rotary engine and miniaturization example of micro rotary engine in U C Berkeley,. Basic parameters, processing methods and parts structures of a micro rotary engine were designed. Structure strength of the micro rotary was analyzed. The micro rotary engine was processed and the pneumatic micro rotary engine test bench was presented.On the premise of the work efficiency was ensured and the heat loss was reduced and the combustion efficiency was reduced and the reliability of ignitionmicro was ensured. The effects of the volume and the compression ratio and the volume influence by quenching distance were consided synthetically. The basic dimension parameters were determined. According to the simulation of a three-zone quasi dimension model, the rule of change of the temperature and the pressure and the volume were analyzed. The possibility of the design was proved in theory.By the basic dimension parameters, the major parts were designed. 3D parts models were assembled to prove the rationality of the overall structure. Then 2D engineering drawings were obtained and modified to improve design efficiency. Structure strength of the rotor and spindle was analyzed through COSMOS Works to determine the material and ensure the safety factor fulfill design requirements.The primary part of micro rotary engine was processed. The pneumatic micro rotary engine test bench was presented. Study the relation of power out and speed with inlet gas pressure. The study proved that the program is doable.
