基于MIL-STD-1797A中关于Ⅳ类飞机的飞行品质规范,对小展弦比飞翼战机的滚转轴操纵效能进行了研究.建立了滚转性能要求和滚转操纵效能要求之间的关系,由于翼身融为一体,飞翼的滚转轴转动惯量通常比常规战斗机大很多,因此其对滚转轴操纵效能的需求更大;由于取消了垂尾,小展弦比飞翼的横向静稳定性较小,操纵面偏转产生的侧力也较小;由于采用多组新型操纵面及控制分配技术,飞翼战机可以实现三轴操纵解耦;因此在侧风起降、非对称装载情形下,与常规飞机相比,小展弦比飞翼战机对滚转轴操纵效能的需求具有诸多新特点.
Based on the MIL-STD-1797A flight quality specifications for Class IV aircraft, the roll axis control performance of small aspect ratio aircraft was studied, and the relationship between roll performance requirements and roll control performance requirements was established, Due to the integration of the wing body, flying wing rolling axis inertia is usually much larger than conventional fighter jets, so its roll axis control performance needs greater; due to the cancellation of the tail, the small aspect ratio flying wing lateral static stability Smaller, the control side of the deflection generated by the side force is also smaller; due to the use of multiple sets of new control surfaces and control the distribution technology, the flying fighter can achieve three-axis manipulation decoupling; therefore in the crosswind takeoff and landing, asymmetric loading, and Compared to conventional aircraft, the small aspect ratio flying wing fighter has many new features for the control of roll axis performance.
