| 摘 要： | 推导了基于发动机推力估算起飞总重和基于旅客座位数估算起飞总重的公式。通过多种大中型喷气式民用客机相关参数的统计值,建立起飞总重对相关参数的多元回归分析模型,通过显著性检验,说明模型是有效的,并据此建立了新的起飞总重估算公式。通过算例结果分析表明,新的起飞总重估算公式具有很高精度。在新机的方案设计阶段若能给定此公式所需的相关参数,可以计算得到相对合理的设计起飞总重值。

| Abstract: | Formulas for estimating civil airplane take-off weight based on engine thrust and seating capacity are presented respectively.Through a variety of jet civil airplanes′ statistical data of related parameters,the multiple regression analysis model of take-off weight with respect to the related parameters is built.The significance test shows that the model is effective,and a novel formula for estimating civil airplane take-off weight is established.The analysis of examples shows that the new formula is accurate.If the parameters required is given in the scheme design stage,then the relatively reasonable design take-off weight value can be obtained by the method of this paper. |
