Research on Calculation of Flap Load for Turboprop Aircraft

襟翼是机翼上用来改善气流和增加升力的可操纵装置,是飞机需要校核的重要部件之一。本文对某涡轮螺旋桨飞机的襟翼载荷进行计算,以风洞数据为基础,采用等效盘模型考虑螺旋桨滑流影响工程算法计算襟翼载荷,与以计算流体力学(CFD)考虑滑流喷流影响计算为基础所计算襟翼载荷进行比较。通过对比分析,得出采用工程算法可以有效且快速的反映襟翼载荷情况,在基本满足工程应用需求的前提下更加高效便捷。

Flaps are controllable devices on wings used to improve airflow and increase lift,and are one of the important components that need to be verified in an aircraft.This article calculates the flap load of a turboprop aircraft,based on wind tunnel data,using an equivalent disk model to consider the influence of propeller slipstream engineering algorithm to calculate the flap load,and compares it with the calculated flap load based on computational fluid dynamics(CFD)considering the influence of slipstream jet.Through comparative analysis,it is concluded that using engineering algorithms can effectively and quickly reflect the flap load situation,making it more efficient and convenient while basically meeting the requirements of engineering applications.
