摘要: 传统舰载机采用纵杆控制迎角,油门杆控制下滑的着舰控制方式存在着操纵通道功能耦合,航迹与姿态耦合,着舰精度不高等多种不足。受舰尾流扰动、航母甲板运动等不利因素的影响,飞行员需要进行高频次的下滑修正操纵,身心负担极重。针对这一问题,在对美军魔毯技术(MAGIC CARPET)系统构成与着舰过程分析的基础上,针对三翼面布局飞机提出了一种基于多操纵面控制分配的综合直接力控制(IDLC)人工着舰精确控制方法。仿真分析表明:基于特征结构配置(EA)解耦设计直接力着舰控制方法能够实现飞机纵向运动长周期模态与短周期模态的解耦、油门通道与纵杆通道的解耦,具有抑制舰尾流扰动、稳定飞机下滑状态、减小操纵负担的功能;而基于多操纵面控制分配的设计方案通过鸭翼正偏增升,不但充分发挥了三翼面布局飞机气动舵面增升控制的优势,还减小了平尾配平出舵量,在一定程度上减小了平尾上偏所带来的升力损失。

Abstract: The traditional landing control mode of the carrier-based aircraft, which uses the pitch lever to control the angle of attack and the throttle lever to control the glide, has many shortcomings, such as the coupling of control channel, coupling of track and attitude, and low landing accuracy. Due to the adverse factors such as ship wake disturbance and carrier deck motion, pilots need to frequently conduct glide correction control, which is a heavy physical and mental burden for the pilots. Based on the analysis of the structure and landing process of the U.S. military MAGIC CARPET system, an Integrated Direct Lift Control (IDLC) landing control method for the triplane configuration aircraft is proposed based on control allocation of multiple control surfaces. The simulation results show that the direct force landing control method based on the Eigen-Structure Assignment(EA) decoupling design can realize the decoupling of long period mode and short period mode of aircraft longitudinal motion, and decoupling of the throttle channel and the longitudinal control channel. The design scheme based on control allocation not only gives full play to the aerodynamic advantages of the three wing configuration aircraft, but also reduces the trim amount of the horizontal tail and decreases the lift loss caused by the upward deflection of the horizontal tail.

Key words: landing control, direct lift control, eigen-structure assignment, control allocation, flight control
