摘要
为了提高飞翼运输机纵向飞行品质,首先研究了该类飞机纵向气动性和操纵特点,并给出了确定其重心前后限的设计方法;然后给出了飞翼运输机纵向操纵能力的计算方法并进行了计算分析;最后,针对飞翼运输机纵向本体稳定性不满足要求的问题,研究了提高飞翼运输机纵向飞行品质的有效方法。研究结果表明,飞翼运输机特有的操纵特性可提高其升阻比,通过合理设计重心前后限以及增稳系统控制律可以保证飞翼运输机具有满意的飞行品质。
For increasing the longitudinal flying qualities of the flying wing transport,the aerodynamics and control characteristics were researched firstly. The design method to ascertain the forward and after center gravity limits of the aircraft was given. Then,the control capacity of the flying wing transport was calculated with suggested method. At last,for the problem of the longitudinal stability of the flying wing transport couldn＇t meet the requirements,the effective measure was researched to improve the longitudinal flying qualities. Research results show that the flying wing transport has special control characteristics to pursue high lift-drag ratio. Reasonable design of the forward and after center gravity limit and the stability augmentation system control law can assure satisfied flying qualities for flying wing transport.
