"系列核心机及派生发展"的航空发动机发展思路

核心机的派生发展一直受到航空发达国家的高度重视，并成为发动机系列化发展的主要技术途径。根据我国目前的发动机发展现状。本文提出了“系列核心机及派生发展”的发动机发展思路，对核心机技术及核心机的派生发展进行了讨论和分析。详细介绍了5个核心机的基本参数，通过这5个核心机派生发展形成的系列化发动机，其推力可以覆盖200～20000daN范围，基本能够满足我国军民用飞机发展对动力装置的需求。

Idea of Aero-engine Development by"Core-engines in Series and Derivation"

Derivation of core engine has been highly recognized among the advance d aviation countries, and has become a major approach to develop a series of aer o engine. Based on the situation of engine development in China, this paper pres ents an idea of "core engines in series and derivation", discusses and analyzes the technology and development of the core engine. The paper introduces the basi c parameters of 5 core-engines in detail. The thrust of the engines derived from the 5 core-engines ranges from 200 to 20 000daN. These engines will meet the ne eds of both military and civilian airplanes in China.
