Abstract. A set of test system, which is suitable for static test of a hyperstatic aero-engine pylon structure of a certain aircraft, was designed according to the requirements of static structure test. This test technology solved some key problems such as support stiffness simulation of hyperstatic engine pylon and aero-engine loading simulation. Based on these experimental techniques, the static test on a hyperstatic aero-engine pylon of a certain aircraft has been completed in the paper. The test results testified to the stable and reliable working performance of the test system. And the aero-engine pylon, the test specimen, didn’t produce any crack or harmful large deformation under all work conditions, indicating that it has met the design requirements on both static strength and stiffness. The test technology can be applied in static tests of similar hyperstatic test specimen. The test data can serve as a basis for structural static strength and stiffness property evaluation of the aero-engine pylon.

Keywords: static structure test, stiffness simulation, static indeterminate, aero-engine pylon.
