摘　　要：针对民用运输类飞机最大能量刹车风险评估的需求,详细对比分析了最大能量刹车试飞过程和最大起飞质量加速-停止距离试验过程的异同,并以飞机滑跑过程中动力学分析为基础,提出了以最大起飞质量加速-停止距离试验结果估算最大能量刹车滑行距离和刹车吸收的能量的工程估算方法。该工程估算方法在ARJ21—700飞机最大能量刹车试验中得到初步验证,表明该工程估算方法有一定的准确性,可以用于民用运输类飞机最大能量刹车风险评估。Based on maximum brake kinetic energy accelerate-stop distance flight test risk analysis,maximum brake kinetic energy accelerate-stop distance and maximum takeoff weight accelerate-stop distance are contrasted,and according taxiing dynamics analysis,a taxiing distance and braking kinetic energy evaluation method is proposed.The evaluation method has been used in ARJ21-700 flight test,which has been proved to be precise.So the evaluation method could be popularized in other transport category airplanes maximum brake kinetic energy accelerate-stop distance flight tests.
