| Abstract: |
| The work aims to research the effect of wind field at high altitude on the stage separation of aircraft during flying. A stage separation model of aircraft was established. The sway distance of the lower stage and the gaps of two key points of aircraft after its stage separation were simulated. The sway distance of the lower stage and the gaps of two key points of aircraft all met the design conditions and requirements when the minimum wind speed and the simulated one were respectively 34 m/s and 40 m/s. Therefore, the minimum wind speed for flying could be relaxed to 40 m/s. When the maximum wind speed was 45 m/s, the sway distance and the gaps above all exceeded the design values, so the stage separation would be affected by it. It proves that the stage separation of aircraft will be affected by high altitude wind in some way, and the sway distance of the lower stage and the gaps of two key points of aircraft will be increased with the increase of high altitude wind speed. |
