A posture evaluation method for aircraft wing based on a simple measurement system

Abstract

Posture alignment is a basic process for the joining of large-size components of aircraft, while posture evaluation is the first problem to be solved for posture alignment. The current posture evaluation method is dependent on advanced measurement equipments, which is not favorable for the wide application. Aimed at the shortcomings, this article puts forward a kind of posture evaluation method for aircraft wing. In the method, a simple measurement system composed of several linear displacement sensors is constructed, which can realize the rapid measurement of the wing posture. Then, the wing posture evaluation problem is transformed into a registration problem between space points and surface. Based on the iterative closest point algorithm, the wing posture evaluation algorithm is presented. An industrial example is presented to validate the proposed method, and the results suggest its feasibility.
