飞机结构部件飞行载荷估算方法研究

 介绍一种考虑飞机各部件间相互影响（干扰）的气动载荷估算方法。把该方法用于估算全动平尾的飞行载荷,并用它估算了Ｆ－７全动平尾在对称机动情况下的飞行载荷,且与飞行实侧载荷作了比较。结果表明,估算和实测载荷相差１０％左右。这种估算方法,在飞机设计阶段,可用于估算飞机其它部件（机翼、垂尾等）飞行载荷。

ASTUDY ON FLIGHT LOAD ESTIMATION OF AIRCRAFT STRUCTURAL COMPONENTS

This report mainly presents an aerodynamic load estimating method which includes the interactive influences between aircraft structural components,and studies how to use this method to estimate all movable horizontal tail flight load. This method has been used to estimate all movable horizontal tail flight load of F-7in the symmetrical maneuver flight case. The esti- mated load is also compared with flight measured load. The compared results show 10% magni- tude difference between the estimated and measured loads.The estimating method and measuring method are validated each other by this comparison. Then this estimating method is also ex- tended to estimate flight loads on other components(wing,vertical tail,etc.)。
