摘　　要：为研究舰载机逃逸过程中的动力学特性,建立了舰载机的六自由度飞行动力学模型。为充分考虑复杂海洋环境的影响,引入了Dryden大气紊流模型、航母舰首紊流模型和航母运动模型,生成了工程化的模拟逃逸环境。在此基础上,分析了紊流速度和紊流速度梯度对飞气动参数的影响,并采用仿真方法模拟了舰载机逃逸的全过程。结果表明,海上复杂环境会影响舰载机正常飞行姿态,加大横向位移和滑跑距离,影响飞行安全。In order to simulate the dynamic characteristics of the carrier aircraft＇s escaping,a flight dynamic model of six-degree-of-freedom is presented. In order to reflect the influences of complicated ocean environment,the Dryden atmospheric turbulence model,turbulence model of carrier＇s bow and carrier movement model are implemented,and the engineering escaping environment is made. Based on these,the influence of the velocity and its grads of turbulence are analyzed and the numerical methods are conducted to simulate the process of the carrier aircraft＇s escaping. The result shows that the existing of the environment on the sea will affect the carrier aircraft＇s normal flight posture,enlarge the lateral displacement and running distance,finally,the safety of the aircraft＇s recovering will be affected.
