近耦合鸭式布局鸭翼展向零质量射流控制技术实验研究

结合鸭式布局和机翼展向吹气的优点,采用鸭翼展向零质量射流间接涡控技术提高战斗机大迎角和过失速机动性能。其主要利用鸭翼涡与主翼涡之间的有利干扰,零质量射流直接增强鸭翼涡,同时间接增强主翼涡。本文利用低速风洞测力测压实验,研究展向零质量射流对近耦合鸭式布局增升影响规律。在不同雷诺数下,通过改变零质量射流的频率来揭示零质量射流与鸭式布局气动力之间的关系。本研究为新一代战斗机研制提供一定的技术储备。

Experimental study on vortex-control technology of canard-spanwise synthetic jet actuators on close-coupled canard configuration

Combining with the advantage of the close-coupled canard configuration and wing-spanwise blowing,the indirect-vortex-control technology of canard-spanwise synthetic jet has been used to improve the high-attack and post-stall maneuverability of fighter.By making use of the advantageous interaction between canard and wing vortex,synthetic jet can strengthen the canard vortex directly and strengthen the wing vortex indirectly.In this paper,on basis of wind-tunnel force and pressure measurement,the effect of ca...
