参数化发动机结构方案设计系统的研究

介绍在微型计算机上以ＡｕｔｏＣＡＤ图形软件为支持软件，研究并开发了适合于涡扇、涡喷、涡轴等类型航空发动机的部件及总体结构方案图的设计系统。由于采用参数化的绘图方式、设计、绘图与修改极为方便。设计工作使用Ｅｎｇｉｎｅ系统可以在很短的时间内，完成多方案的部件及总体结构方案设计，为航空发动机进行初步总体结构设计提供简便、快捷、多方案优化选择的方法，Ｅｎｇｉｎｅ系统可以大大地改善发动机结构设计的速度和质量。

A RESEARCH ON AN AERO-ENGINE STRUCTURE PARAMETRIC DESIGN SYSTEM

An ENGINE design system was developed under micro-computer's AutoCAD version.The system is used to design the structure scheme of a whole aeroengine or its parts.The type of engine may be turbofan,turbojet or turboshaft.It is very convenient to design,draw and modify due to the system's inner parametric drawing mechanism.Multiple schemes of the engine and its parts can be designed with the system in a short time,which gives an agile and convenient way for aeroengine's primary structure design.The ENGINE system will greatly improve the design speed and quality of an aeroengine.
