美国战斗机发动机技术研究与产品研制的发展特点及趋势分析

Review on Technical Investigation and Product Development of Fighter Engine in US

旨在为战斗机发动机技术研究和产品研制提供参考与借鉴,全面综述了美国战斗机发动机技术研究与产品研制的发展历程和典型成果,并归纳和总结了其发展特点与趋势:技术研究是产品研制的坚实基础,而核心机和发动机验证机只是用于开发与验证技术,特别是正在验证的自适应循环技术还需要深入验证;型号研制受国防武器需求牵引,是众多先进技术的有机集成;提高技术指标始终是战斗机发动机的发展趋势;高可靠性和耐久性是型号使用的必然要求,并逐步成为发展趋势;提高经济可承受性是航空发动机最终追求目标。

Aim to provide references for fighter engine technology investigation and product development, the development course and results of U.S. fighter engine were summarized based on the literatures. The development characteristics and tendency of U.S. fighter engine were summarized based on results of introducing fighter engine development. The research results show that technical development is solid foundation for product development, core engine and engine demonstrator are used for technical development and demonstration, and the adaptive cycle technology need to be demonstrated deeply. In terms of product development the engine model development pulled by national defense weapon demand was organically integrated by the various advanced technologies. The development tendency of the fighter engine is the engine performance improvement all the time, and the improvement of the engine reliability and durability is the inevitable requirement, and that would become the development tendency. The final goal of aero engine development is the economic affordability improvement.
