空中加油时,加油机的气动力和力矩对受油机的操纵影响较大。需对影响大小进行定量分析,得出确定结论。本文对受油机的横侧动稳定性及操纵性进行了研究,确定了作用在受油机上由加油机翼端涡场引起的气动力和力矩的大小,提出一种简化气动模型,并将导数形式的力和力矩用于线性运动方程。研究表明,受油机具有发散的振荡特性,且主要由倾斜和侧向移动组成;飞行员在飞行时可通过不断操纵副翼来控制发散模态,保持飞机稳定。
When refueling in the air, the aerodynamic force and torque of the tanker have a greater impact on the operation of the oil tanker. It is necessary to quantitatively analyze the impact size and reach a definite conclusion. In this paper, the lateral dynamic stability and maneuverability of the oil receiver are studied, and the aerodynamic force and torque acting on the oil receiver caused by the tip-vortex field of the fuel filler are determined. A simplified aerodynamic model is proposed, Derivative force and moment are used for linear equations of motion. Studies have shown that the receiver has divergent oscillation characteristics and is mainly composed of tilt and lateral movement. The pilot can control the divergence mode by continuously manipulating the ailerons while flying to keep the aircraft stable.
