摘　　要：针对现有小型转子发动机微型化后存在的诸如尺寸较小装配困难、压缩比对燃烧效率及热损失的影响等问题,并综合考虑熄火距离对燃烧室的影响容积比例,选择基本尺寸参数的选择,通过三区准维模型对微型转子发动机的基本性能进行初步计算,得到基本性能参数。最后采用一体化设计方案完成微型转子发动机的设计,证明基本参数设计方案的可行性,为转子发动机的微型化提供参考。The problems in miniaturization of rotary engines are considered, such as assembling difficulties in small size, complex surfaces processing problems when traditional processing methods cannot be used, and the quenching distance influence on the stability of combustion. Performance parameters of a micro rotary engine were calculated through a three - zone quasi dimension model to determine the basic dimension parameters. Integrated processing was adopted in the design of the micro engine to prove the feasibility of the selected parameters in this design scheme, which can provide reference for miniaturization of the rotary engine.
