Method and device for calibrating load sensors

摘要

A device and a method for calibrating load sensors which are provided at least one load cross-section of an aerofoil or control surface of an aircraft, the load sensors being calibrated on the basis of load coefficients (αi) of the load sensors, which load coefficients a calculation unit calculates by evaluating a linear system of equations formed by means of mechanical loading of the aerofoil or control surface.

1. A system for calibrating load sensors of an aircraft, comprising:
an aerofoil or control surface of the aircraft; load sensors, which are, provided at at least one load cross-section of the aerofoil or control surface of the aircraft, the load sensors being adapted to supply measurement signals to a calculation unit; and the calculation unit being adapted to calibrate the load sensors by load coefficients (αi) of the load sensors, which load coefficients are calculable, by the calculation unit, by evaluating a linear system of equations formed by mechanical loading of the aerofoil or control surface; wherein the calculation unit is adapted to calibrate the load sensors during a loading measurement, in which the aerofoil or control surface is loaded continuously with a preset transverse load profile which is caused in each case by a corresponding flight maneuver of the aircraft located in the air.
