Airfoil incidence angle adjustment method

摘要

A method of providing interchangeability of aircraft wings, particularly providing a method of adjusting the angles of incidence and dihedral to compensate for differences in the twist angle between airfoils. The method comprises determining the angle of twist of an airfoil, having an airfoil attachment member, and supporting the airfoil on at least three supports spaced about said airfoil so that the airfoil attachment member is aligned with a hole boring means. The supports are adjusted so that the hole when bored through the airfoil attachment member provides the airfoil with angles of incidence and dihedral that substantially cancel the angle of twist. The hole is bored through the airfoil attachment member.
