%X According to experimental technology specifications of pylon static testing of civil aircraft engine, an experimental system for pylon static testing was designed and manufactured, which solved several key technologies, such as pylon support simulation, loading boundary simulation etc. The applied moment is the combination of couple and load shift. The small load for testing was applied by a self-designed loading level. According to testing requirements, three dangerous working conditions related with emergency landing test and heading lateral test were carried out. Results show that the testing system is stable and reliable; the pylon has enough strength and stiffness in above-mentioned working conditions. These results may be used for the strength and stiffness evaluation for engine pylon, and offer data for the building of pylon finite element model.
