Abstract

The invention relates to a device for an installation structure fireproof test under engine suspension static loading, which belongs to the technical field of aero-engine detection and comprises a main frame mechanism, a rotatable upper cantilever mechanism, a load loading mechanism, a tension detection mechanism, an engine mass center adjusting mechanism and a rotatable lower bracket mechanism. The rotatable upper cantilever mechanism is fixedly installed on the upper portion of the main frame mechanism and rotationally connected with the load loading mechanism, the lower end of the load loading mechanism is connected with the tension detection mechanism, the lower end of the tension detection mechanism is fixedly connected with the engine mass center adjusting mechanism, and the engine mass center adjusting mechanism is fixedly arranged on the aero-engine. The rotatable lower bracket mechanism is arranged on the lower portion of the main frame mechanism and fixedly connected with the lower end of the aero-engine, and the aero-engine fire protection device can be matched with various existing fire protection devices and can be suitable for different force application angles of different engines.

Description

technical field [0001] The invention belongs to the technical field, and more specifically relates to a device for a fireproof test of an engine mount under static loading. Background technique [0002] The existing aircraft engine installation structure will bear static loads during operation, and its installation points are designed on aluminum components. It is generally believed that aluminum has poor flame resistance. Once the installation structure fails in whole or in part, the installation structure will not be able to maintain sufficient The strength to withstand the corresponding static load, resulting in unintentional engine disengagement, resulting in hazardous engine consequences. [0003] Existing aircraft engines contain four engine mounting points, two on the gearbox aluminum housing, one on the aluminum cylinder head, and one on the aluminum oil pan. Depending on the material properties, aluminum components are less resistant to flames than steel components...
