摘要
从固定翼飞机陆基滑跃起飞的安全性要求出发,提出了一种预测起飞性能的模型,用于预测最小起飞速度和最短滑跑距离。该模型的特点是非常简单,包含了影响陆基滑跃起飞行性能最为关键的参数。预测结果与飞行试验数据结果取得了很好的一致。作为预测模型的应用示例,讨论了关键参数对滑跃起飞性能的影响。给出的模型和示例方法对制定固定翼飞机陆基滑跃起飞试验方案有实用价值。
Based on the takeoff safety criterion, a ski-jump model was developed to predict a land-based ski-jump takeoff performance for a fixed-wing aircraft. It was to predict the minimum launch speed and the minimum ground roll. The model is fairly simple, but including the key parameters which effect the ski-jump takeoff performance greatly. The predicted results were compared with the flight test results, it showed good agreement between them. The key parameters were also discussed, so as to demonstrate how to use this new method. The model and the method listed are practical for establishing a land-based ski-jump testing scheme of fixed-wing aircraft.
