中文摘要:

大型察打一体无人机能够更好地兼顾侦察、打击、信息传递等功能，是世界范围内军用大型无人机发展的主要方向之一。无人机用发动机在使用方式、监控维护方面与有人机发动机有显著区别，为了分析起飞质量为15～20 t的大型无人机对发动机的基本性能、能力需求和研制模式，采用基于飞机的约束分析和任务分析的方法对发动机基本性能进行计算分析，结果表明：起飞质量为15～20 t的无人机所需发动机的安装推力为39～79 kN。结合有人和无人飞机使用区别，提出大型无人机9个应用场景对应发动机的11个能力领域。在充分考虑中国自主研制发动机交付数量和使用现状基础上，提出了发展低成本无人机动力的 “1+N”模式发展技术途径。

英文摘要:

Large reconnaissance/strike unmanned aerial vehicles （UAVs）， which can better balance functions of reconnaissance， strike， and information transmission， is one of the main directions of the development of military large UAVs worldwide. There are significant differences in usage， monitoring， and maintenance between unmanned and manned aircraft engines. To analyze the basic performance， capability requirements， and development mode of the engine for a large UAV with a takeoff weight of 15-20 tons， fundamental engine performance is calculated and analyzed by aircraft-based constraint analysis and mission analysis. The results show that the installed thrust requirement of the engine is 39kN to 79kN for the UAV with 15-20 tons takeoff weight. Considering the difference between manned and unmanned aerial vehicles， 11 engine capability areas corresponding to 9 mission scenarios of large UAVs are proposed. By fully considering the delivery quantity and current usage status of domestically developed engines in China， a “1+N” mode for developing low-cost UAV engines is proposed.
