METHOD FOR RECONSTRUCTING GUSTS AND STRUCTURAL LOADS AT AIRCRAFT, IN PARTICULAR PASSENGER AIRCRAFT

摘要

A method for reconstructing gusts and/or structural loads at aircraft, in particular passenger aircraft, characterised by the process steps: a) generating an observer on the basis of a nonlinear model of the aircraft which describes the movement of the aircraft in all six degrees of freedom (DoF) and the elastic motion of the aircraft structure; b) continuously supplying all the data and measurements substantial for the description of the state of the aircraft to the observer; c) calculating the gust velocities and structural loads (manoeuvre and gust loads) by the observer from the supplied data and measurements.
