Fuselage test of a small aircraft according to CS‐23 requirements

Abstract

This article describes a static strength test of a fuselage of a small aircraft. Tests were done according to CS‐23 requirements. The test program was firstly analysed and then a methodology of the entire test was created and the test could be built. The requirement of the submitter was that the bending and torque moment and shear force had to be as close as possible to calculated loads. This problem requires many loading forces along the length of the fuselage, and we had to solve how to load several tonnes along the 7 meters. For this purpose, a loading tree and rollers were used. The conclusion of this article describes how using rollers with the loading tree changes forces and describes the test arrangement.

Straipsnyje nagrinejamas mažo lektuvo liemens statinis stiprumas. Bandymai buvo atliekami pagal CS‐23 reikalvimus. Pirmiausia buvo analizuojama bandymu metodologija ir programa, po to buvo sudaryta bandymu seka. Pateikejas reikalavo, kad lenkimo ir sukimo momentubei skersiniu jegu apkrovos būtu kiek galima artimesnes apskaičiuotoms apkrovoms. Reikejo apkrauti liemeni jegomis daugelyje vietu, tad tyrejams teko spresti, kaip išdestyti daug tonu 7 metru atkarpoje. Šiam tikslui buvo panaudotas apkrovu medis ir skridiniai. Šio straipsnio išvadose apibūdinta, kaip keičiamos jegos naudojant skridinius ir apkrovu medi. Taip pat aprašyta bandymu iranga.
