为了开发出一种无曲柄连杆机构的大缸径二冲程点燃式活塞发动机,参考国外设计专利,运用三维CAD软件构建发动机概念电子样机,分析发动机结构与工作原理。结果表明:新型大缸径无连杆发动机结构能满足航空活塞发动机高效率、高功重比的需求,具备较高的应用价值。
In order to develop a large-bore two-stroke ignition piston engine without crank mechanism, reference to foreign design patents, the use of three-dimensional CAD software to build the engine concept of electronic prototype, analysis of engine structure and working principle. The results show that the new large-bore, rodless engine can meet the requirements of high efficiency and high weight-to-weight ratio of aero-piston engine and has high application value.
