摘　　要：为了研究甲板运动对舰载机弹射起飞性能的影响,为弹射起飞控制策略设计提供依据,首先分析了舰载机弹射起飞受力与运动情况,以及弹射器与起落架等对飞机产生的力和力矩;建立了舰载机弹射起飞的动力学模型,并设计了弹射过程中的增稳飞行控制律;最后,在中等海况下对弹射起飞的过程进行了数值仿真。仿真结果表明,离舰时不同相位的甲板运动对飞机起飞将产生不同的影响,甲板纵摇对舰载机离舰后下沉量影响较大。同时,甲板横摇对舰载机离舰后侧向偏移和姿态影响很大,对离舰后下沉量也会产生影响。In order to research the effect of deck motion on the performance of carrier-based aircraft cata- pult launch, and to lay the foundation of the design of catapult launch control strategy, firstly, this paper analyzes the force and motion of the carrier-based aircraft during the catapult launching process, consider- ing the force and moment of the catapult and landing gear on aircraft ; and then establishes a mathematical model and designs the control law of augmentation system during launching. Finally, the simulation is done at medium sea conditions, and the results show that the effects of deck motion on takeoff vary with phase： the longitudinal shaking has great influence on sinkage after taking off, while the lateral shaking has influence on lateral deviation and flight attitude as well as sinkage.
