【摘要】 推力矢量是第四代战斗机获得过失速机动性的必要条件,而二元喷管又是推力矢量控制中性能较为优越的一类喷管。本文较全面地阐述了目前世界上推力矢量和二元喷管的发展和现况、二元喷管的构造和性能、二元喷管对改进飞机升阻特性和机动的作用。推力矢量能显著提高飞机在空战中的作战效率以及推力矢量控制所需的效能也在文中作了介绍。更多还原

【Abstract】 Vectoring thrust is a necessary measure in obtaining post-stall maneuverability for the fourth generation fighter aircraft.Two-Dimensional(2-D) nozzle is superior to other nozzle-s,such as symmetrical nozzle,in performance of rectoring thrust control.In this paper,the development and status of vectoring thrust and 2-D nozzle in the world,the construction and performance of 2-D nozzle,the effect of 2-D nozzle in enchancing the lift-drag characteristics and the maneuverability of a fighter aircraft are described in rather detail.Furthermore,the improvement of efficiency in air combat of an aircraft with vectored propulsion and the power needed in vectored propulsion control are also presented.更多还原
