Possibilities and Methods of In Flight Loading Measurements

This article provides information about in-flight measurement of a small sport aircraft. Firstly the strain gauges were installed into the wing structure and then the calibration procedures were done. After the calculation of strain gauge coefficients the equations for calculating of bending moments and other variables were established. The data acquisition system was installed into the aircraft for measurement responses from strain gauges and other variables as speed, altitude, load factor and temperature. Many flights were performed with this way equipped aircraft and after that the recorded data were analyzed and those results were compared with the calculation and with the static strength tests performed before.

Úkolem bylo stanovit zatížení na křídle malého sportovního letounu v závislosti na režimu letu a zároveň i napětí ve vybraných místech konstrukce v závislosti režimu letu.
