MATRIX FORMULATION FOR CALCULATIONS OF WING LOADING DISTRIBUTION

摘要

An aeroplane is influenced by wide spectrum of loads during operations. The spectrum of loads is given by flight and landing load cases, mass and operation configurations leading to a great number of load cases that all have to be taken into consideration for loading of an aeroplane. The automation of computation is necessary and cannot be done without modification of the computation methodology. The paper describes the process of wing loading computation using a matrix formulation. This formulation simplifies the solution of complicated and time consuming dynamic loading, caused by numerical methods, and enables the selection of the essential loads in a uniform data basis. Explanation is based on an example of a wing loading. The method, described in this paper, was successfully applied in the CAE system for aeroplane loading computation, named SAVLE (System for Automation of Load Calculation of Aeroplanes), which was used in Czech aircraft industry during the development of several aeroplanes.
