调整片气动助力操纵是指驾驶员通过机械式操纵系统操纵调整片,再由调整片偏转产生的气动力操纵主舵面的一种操纵形式,主要应用在高速大型飞机上。此种操纵系统动态特性的计算方法一般资料中比较少见,参考文献[1]仅给出了升降舵系统的简化方程。本文由拉格朗日方程导出此种操纵形式的升降舵、副翼和方向舵操纵系统的运动方程,并以升降舵系统为例,在电子模拟计算机上计算了某国产大型客机的升降舵系统对数幅、相频特性。文中将计算结果与真实系统的地面模拟试验作了比较。这些比较表明,本文所提供的方法在工程上是可行的。
Pneumatic Pneumatic Boost Control refers to the driver manipulating the regulating piece through the mechanical control system and then the aerodynamic force generated by the deflecting piece to manipulate the main rudder surface. It is mainly used in the high-speed and large aircraft. The calculation method of the dynamic characteristics of this control system is relatively rare in the general information, reference [1] only gives the simplified equation of the elevator system. In this paper, the equations of motion for the elevator, aileron and rudder steering systems of such manipulations are derived from the Lagrange equations. Taking the elevator system for example, the logarithmic amplitude of the elevator system of a domestic large passenger aircraft is calculated on an electronic simulation computer. Phase frequency characteristics. In this paper, the calculation results are compared with the real system ground simulation test. These comparisons show that the method provided in this article is technically feasible.
