Original Abstract

The paper provides description of FEM stress analysis of several landing gears for new Czech aircraft. In all loading cases, there is considered material and geometric non-linearity, contacts and friction between some parts of landing gear and carried out verification of analysis results with comparative testing. The structural tests of the landing gears of Zlín Z143-L, small GA and aerobatics plane and KP2U-Sova, an ultralight plane , were tested in the IAE laboratory. The structural test of nose and main landing gear of Aero Vodochody s new commuter were tested in test laboratory of Technometra Radotín, the Czech producer of landing gear.
