摘要
对高超声速飞行器侧向机动性能的研究是对其进行跟踪预测的一项重要参考依据。通过对高超声速飞行器的最小转弯半径以及偏航距离的计算,研究了飞行速度以及飞行高度对飞行器侧向机动性能的影响。首先在假设条件下构建了飞行器的数学模型,然后建立了飞行器做变速率转弯机动时的转弯半径模型、位移模型以及加速度模型,通过计算两种转弯模式下的最小转弯半径以及匀速率转弯机动方式下的偏航距离,得出了关于飞行速度以及飞行高度会对飞行器机动性能产生不同影响的结论。
Research on side maneuverability was a very important reference to tracking and prediction of hypersonic vehicle.Based on calculating minimum turning radius and yawing distance,the influence of velocity and height to the side maneuverability of hypersonic vehicle was researched.First,mathematic model of vehicle was established under certain assumption.Second,the turning radius model,displacement model and acceleration model of hypersonic vehicle under variable-rate turn maneuver was established.After calculating minimum turning radius of two turning mode and yawing distance of constant turning mode,it was concluded that velocity and height would bring different influence to the maneuverability of hypersonic vehicle.
