FIELD: mechanical testing of objects in rocket and space technology. SUBSTANCE: process of ground test of panel structure of aircraft for strength consists in simultaneous action on tested panel structure both by wide-band noise generated by running-out gas jet of jet engine and by thrust force of given jet engine according to specified time law of loading. In this case specified load is uniformly distributed over outline of cross-section of tested panel structure. Gear for implementation of process of test of panel structures of aircraft for strength has frame with fixture to anchor tested panel structure, jet engine, mobile platform with steady-rest to attach jet engine, rigid tie-rods coupling face plate to mobile platform, regulator of speed of displacement of mobile platform. Mobile platform is installed in guiding through grooves of frame. Face plate comes in the form of ring and is provided with continuous circular groove. Tested panel structure is anchored in said fixture of frame and in continuous circular groove of face plate. EFFECT: increased reliability of testing by its approximation to operational conditions. 2 cl, 2 dwg
