Abstract

The new ACLAD philosophy for launcher/spacecraft mechanical-coupled load analysis (CLA) is presented. ACLAD stands for “A CLA a Day”. We encourage the development of a work method that would allow spacecraft manufacturers to perform a very high number of CLA, instead of once or twice per each program as done today. Such analyses provide the best possible estimation of the spacecraft loads during flight and often underline that the mechanical requirements are much higher than the actual need. If performed many times during a project, CLA could help prevent overdesign and overtesting by inducing lower specifications. Lower costs and mass of the structures could be attained. Some possible implementations of ACLAD are presented in this paper.
