System and method for determining characteristic parameters in aircraft

Abstract

The present invention provides a method and a calculation system (1) for an aircraft (2) comprising at least one sensor (3) for detecting aeroelastic and flight mechanical motion parameters of the aircraft (2), for detecting positions and motions of control surfaces of the aircraft (2), or for detecting speeds of wind gusts acting on the aircraft (2); and comprising a calculation unit (4) that calculates parameters characteristic of passenger comfort and cabin safety (2) and motion parameters of the aircraft (2) based on sensor data provided by the sensor and a non-linear simulation model of the aircraft.

Description

technical field [0001] The invention relates to a computing system for an aircraft and to a method for determining characteristic quantities and momentum of an aircraft. Background technique [0002] Aircraft such as airplanes or helicopters are subjected to various forces during flight. Variables that have significant influence in this regard are: the lift generated by the wings, the aerodynamic drag of the aircraft, the force of gravity or gravity acting on the center of gravity of the aircraft, the shear forces generated by the engines, the forces on the control surfaces of the aircraft The resulting adhesive forces and the moments caused by the individual forces. The mass inertia of the aircraft or the mass inertia of aircraft components also contributes to the aforementioned forces. Flight maneuvers and air turbulence create structural loads on the aircraft. [0003] In order to predict the flight behavior of the aircraft, a system of equations is used which is compl...

Problems solved by technology

[0004] However, the calculation accuracy of these traditional calculation systems using roughly linear models is thus relatively poor, ie they do not reflect the actual behavior of the aircraft in a sufficiently accurate manner
