摘　　要：爬升是飞行中的重要阶段,最大速度爬升是运输飞机通常采用的爬升方式。本文针对最大速度爬升过程,以空气动力参数为主要指标,分析了最大爬升率与爬升真空速和爬升角的关系。以ARJ21飞机为例,分析了民航运输飞机爬升真空速与高度的变化关系,爬升角与高度的变化关系,最大爬升率与高度的变化关系,计算了飞机爬升性能的主要参数。Climbing is an important stage in flight.The common climbing method used by transport aircraft is maximum speed climbing.The maximum speed climbing is analyzed by aerodynamic parameters.The relationships between maximum climbing rate and true airspeed and between maximum climbing rate and climbing angle are analyzed in this paper.With ARJ21 aircraft as an example,the relationships between true airspeed and altitude,between climbing angle and altitude and between maximum climbing rate and altitude are analyzed.The main parameters of aircraft climbing performance are calculated.

关 键 词：爬升性能 最大爬升率 爬升角 空气动力参数
