| 摘要: |
| 为防止舰载机舰面操纵时出现侧滑或者侧翻事故，对舰载机舰面运动品质与操纵转弯特性进行了研究。首先推导了在航母运动状态下舰载机机身转动动力学方程，接着建立了计算侧滑与翻滚临界速度的数学模型；计算了航母运动条件下舰载机滑行时操纵转弯发生侧滑、翻滚的最大转弯速度与转弯角度；并给出了考虑航母运动速度时舰载机的机体翻滚判据和主轮侧滑判据。研究结果表明：相对于地面滑行时的操纵运动，舰载飞机在航母甲板上滑行时的最大允许转弯滑行速度明显下降，尤其是在大风浪气象条件及舰载机远离航母重心等状况下，最大滑行速度降幅更大。该研究结果为我国航母舰载机机动操作规范提供重要的参考依据。 |

| Abstract: |
| To avoid the accident of sideslip or tumbling,the deck motion quality and turning manipulation characteristic of the carrier-based aircraft is investigated. Firstly, the kinetic equation of aircraft body rotation considering aircraft carrier movement is deduced. Then a mathematical models for calculating the critical speed of sideslip and tumbling are established. The extreme turning speed and turning angle of sideslip and tumbling of maneuvering cockpit under aircraft carrier movement condition are calculated. And the body roll criterion and the main wheel sideslip criteria of the carrier-based aircraft are given. The results shows that the maximum allowed turning speed of the carrier-based aircraft is significantly lower than that of the ground maneuvering, especially under heavy wind and waves and when the carrier-based aircraft is far away from the carrier's center of gravity. This study provides the important reference basis for our aircraft carrier aircraft maneuvering operation specification. |
