摘要
建立了飞机着舰下滑穿越舰尾流的六自由度飞行动力学模型。引入舰尾流数学模型,对下滑着舰过程进行了动态仿真。结果表明,舰尾流的周期性分量、稳态分量和随机大气紊流分量是飞机迎角和姿态变化的主要因素,最终导致实际着舰点偏离理想着舰点。
A flight dynamic model of six-degree-of-freedom aircraft during approaching and landing on the cartier is presented. The carrier air wake model from MIL-F-8785C is implemented, and numerical simulations are conducted for aircraft flight through the air wake. Results show that the periodic, the steady and the free air components of the air wake are the main causes making the attack angles, and the attitude angles varying intensely. As a result, the real landing point on the carrier deck departs from the designated touch point.
