The Optimisation of Stick Force during Take-off for Airplanes without Adjustable Horizontal Stabilizer and Aerodynamic Tabs

针对无可调水平安定面和气动调整片的飞机在起飞阶段纵向杆力的优化设计,提出了一种适用于该种飞机的改善起飞杆力的方法,该方法包括了起飞杆力设计速度点选取、目标杆力的确定和随重心而变的升降舵预置偏度的计算。将该方法用于某型机,通过理论计算和飞行员在模拟器上验证,表明该方法行之有效,可以满足飞行品质规范要求。

For the optimisation of stick force during take-off of airplanes without adjustable horizontal stabilizer and aerodynamic tabs, an approach for improved stick force was given. The approach included how to figured out the design speed, how to choose the target stick force and compute the elevator degrees in accordance with center of gravity. The method was finally applied to a certain aircraft. The results of theoretical calculation and the evaluation of pilots by flying flight simulator indicate that this approach was of great value and the results can satisfy the demand of flying qualities specification.
