摘　　要：着陆滑跑距离是重复使用运载器着陆性能中最主要的指标之一,良好的着陆性能对飞行器的安全着陆至关重要。因重复使用运载器滑跑过程复杂,为工程应用需要,简化分析在跑道坐标系下建立飞行器着陆滑跑估算模型,并提出一种简单易懂的滑跑距离估算方法,考虑减速伞和地面风影响,研究不同滑跑工况下的滑跑距离估算方法。该滑跑距离估算方法简洁、算法易实现,适合工程应用。The running distance is one of the most important landing performances for reusable launch vehicles,and the well landing performance is mostly important for safety landing.A running model is built under the runway reference frame,and a simple and pellucid estimated method of the running distance is presented,considering the influence of a dragging umbrella and the ground wind,and estimated methods of the running distance for certain kinds are investigated.The estimated method of the running distance is succinctness,and the arithmetic is easy to realize.The method is appropriate for engineering application.
