摘要
推力矢量喷管能够大幅提升飞行器的机动性,传统机械式矢量喷管因结构复杂、可靠性差等缺点而使用受限,相比之下,气动矢量喷管的综合性能更为突出,已发展出多种类型,包括激波控制型、双喉道型等。本文简要介绍了气动矢量控制技术的发展现状,重点综述了矢量效果最好的双喉道喷管在二元、轴对称模型气动特性和构型优化等方面的研究情况,并基于现阶段研究的不足,对未来发展方向提出设想。
Trust-vectoring nozzle can visibly enhance the maneuverability of aircraft. The applications of mechan-ical vectoring-nozzle are limited due to the complicated structure and poor reliability, while the pneumatic vecto-ring-nozzle has a better performance. Series of pneumatic vectoring-nozzle are developed in recent years. The development of pneumatic-vector-control technology is introduced briefly. The research progress on the aerody-namic performance and configuration optimization of dual throat nozzle is reviewed in detail. Problems in exist-ing research are summarized and the future developments of dual throat nozzle are prospected.
