摘　　要：飞机的起飞总重是飞机的重要设计参数,概念设计阶段首先要做的重要工作之一就是确定飞机的起飞总重。以四人座低速活塞螺旋桨飞机为例,采用任务剖面法和商载航程法分别对起飞总重进行了估算,并对两种方法进行了修正,在此基础上,取两个计算结果的平均值作为最终的起飞总重估算值。通过与对比机型的比较,验证修正后的计算方法和结果是准确合理的,为通用飞机起飞总重的确定和选择提供了参考。The gross weight of take-off is a primary parameter for airplane design. One of the most important works is to determine take-off weight in conceptual design phase. Mission proifle method and payload range method were presented for estimate the gross weight by a design example of a low speed, four-seats, piston-powered, propeller-driven general aviation airplane, and revised these two methods. Depend on this, took the average of two calculation results as the final takeoff gross weight. The estimation results were verified very precise by comparison with the competition airplanes, the results and methods revised can be reference to general aviation airplane project.
