Developments in optimized load calculation and extreme load detection: summary of EADS-CASA's main static loads activities in CleanSky Smart Fixed Wing Aircraft, work package on Advanced Loads Control Techniques

摘要

EADS-CASA's Static Loads Domain participated of the Clean Sky initiative developing several activities targeting the improvement of the available static loads calculation methodologies within the work package on Advanced Loads Control Techniques of the CleanSky Smart Fixed Wing Aircraft project. This paper summarizes the progress made in the two most relevant activities, namely the optimized preliminary load calculation method, also known as aircraft response confinement method, and the extreme load detection method. The first methodology targets the calculation of design loads by means of constrained optimization performed on the loads model, and has shown to be a quick but highly conservative methodology. The second method tries to reduce the number of maneuver simulations by means of optimal case selection, and has shown to be a very powerful and efficient tool.
