摘　　要：针对国产民机起飞离场中的性能参数计算需要,建立了等表速爬升、等马赫数爬升、等爬升率爬升、等爬升梯度爬升以及等爬升比爬升共5种模式下的飞机起飞离场航迹与性能参数计算模型,并以B737-800飞机的基础性能参数为例,对模型进行编程实现。与波音公司BCOP软件相比,二者的轨迹、不同时刻的推力、燃油流量、阻力及爬升率变化趋势一致,总时间、距离及燃油流量的偏差在2.5%以内。研究结果表明,所提算法可应用于国产民机的起飞离场航迹超障安全性、经济性和噪音分析。For the calculation of performance parameters of domestic civil aircraft in take-off and departure, the aircraft take-off and departure trajectory and performance parameters model under five modes of constant indicated airspeed climb, constant Mach number climb, constant climb rate climb, constant climb gradient climb, and constant climb ratio climb were established. Furthermore, taking the basic performance parameters of the B737-800 aircraft as an example to program the model mentioned in the text. Comparing the model with Boeing’ s BCOP software, the change trends of the trajectory and the thrust, fuel flow, drag, and climb rate at different times were consistent. In addition, the deviations of the total time, distance and fuel flow were within 2. 5%. The results show that the proposed algorithm can be applied to the safety, economy and noise analysis of the take-off and departure track of domestic civil aircraft.
