Abstract

The invention discloses a large rocket engine and support integral overturn fixture, which comprises an engine connection main frame and is characterized in that a main body of the engine connection main frame is of a cylindrical structure and comprises a plurality of annular plates which are coaxially arranged at intervals and a plurality of connecting rods which are uniformly arranged at intervals in the axial direction and connect the annular plates together, both ends of the engine connection main frame are connected with two lifting ropes through detachable clamping apparatuses, each two of the lifting ropes are detachably connected with a lifting beam, a rack mounting surface of the engine main frame is provided with a plurality of rack mounting surface cushion blocks, and the inner side and the outer side of each rack mounting cushion block are detachably provided with a rack mounting surface connecting flange and a rack mounting surface reverse-side connecting flange respectively. The fixture disclosed by the invention realizes integral single-arm overturn of a large-size high-mass rocket engine and a support thereof, the overturn process is stable and controllable, and the safety of the engine is ensured. The large rocket engine and support integral overturn fixture has the advantages of high operability and low cost.

Description

technical field [0001] The invention belongs to the technical field of large-scale spacecraft mechanical environment tests, and in particular relates to a large-scale rocket engine and a support overall flip fixture. Background technique [0002] When the rocket engine is subjected to mechanical environmental test assessment, due to factors such as insufficient vibration equipment thrust, generally only a single machine with relatively small mass and size is used as the test piece. With the development of high-thrust shaking tables and the maturity of vibration test technology, the boundary of mechanical environmental test assessment has become more realistic. A large-scale rocket multi-machine parallel engine and support needs to be assessed by mechanical environmental test as a whole. During the test, the engine and bracket need to be connected to the vibrating table fixture in the form of an undercut opposite to the installation direction of the rocket body, and the engin...
