Embodiment Construction

[0023] When operating modern commercial aircraft, it is important to understand the internal loads (bending moments and shear forces) acting on the aircraft structure during flight. These loads are caused by actions directed by the pilot or the Electronic Flight Control System (EFCS) or by turbulence or discrete wind gusts through which the aircraft is flying. However, these loads cannot be monitored by measurements at any desired position of the aircraft. In accordance with the present invention, these loads are reconstructed from flight data available from commercial aircraft (e.g. Euler angles, "body angular rate", acceleration, GPS data), the position of the control surfaces and calculations using a mathematical model of the aircraft . In addition, the gust velocity should be estimated by appropriate means to calculate the loads due to the gust.

[0024] The reconfiguration of the load is of great benefit to the operator of the aircraft. One benefit comes from reacting ...

Abstract

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.

Description

[0001] References to related applications [0002] This application claims priority from German patent application DE 10 2005 058 081 filed on December 6, 2005, the disclosure content of which is hereby incorporated by reference into the present application. technical field [0003] The invention relates to a method for reconstructing wind gusts and / or structural loads on an aircraft, in particular a passenger aircraft. Background technique [0004] External influences such as wind gusts or turbulence, which can lead to increased structural loads at any point of an aircraft, in particular a passenger aircraft, have hitherto been only possible to a limited extent. Of course dynamic loads can be measured, but perturbations or disturbances cannot be inferred. Contents of the invention [0005] It is an object of the invention to provide a method whereby structural loads on an aircraft can be simulated and disturbances thereof can be reconstructed. In particular, a method is...
