Problems solved by technology
The main reason is that the flight test is costly, long cycle, small amount of information harvested, risky, and requires a lot of manpower
This requires the ground test of the engine. The ground test of the engine refers to the static test of the system on the ground according to specific conditions and environmental requirements, and obtains information describing various performance indicators of the system, so as to solve the key problems in the engine thrust test process. However, in the existing technology, there is no mature technology for the experimental equipment of engine thrust

The invention discloses an engine test bench thrust measurement fixed frame. A base is of a cuboid structure, a front mounting seat and a rear mounting seat are fixedly mounted at the front end and the rear end of the base respectively in the length direction of the base, the rear mounting seat comprises a transverse plate and a vertical plate, and the transverse plate and the vertical plate forman L shape; a loading mechanism mounting seat is fixedly mounted on the front mounting seat, and two first fixed frame spring piece mounting seats are fixedly mounted at the front end of the base andlocated on the two sides of the front mounting seat respectively; a fixed frame working force sensor mounting seat is fixedly mounted on the base and located on the center line in the length directionof the base; and two second fixed frame spring piece mounting seats are fixedly mounted at the rear end of the base and located on the two sides of the rear mounting seat respectively. The engine test bench thrust measurement fixed frame is provided with the horizontal base, and the force bearing capacity of the whole fixed frame is improved.
Description
technical field [0001] The invention relates to the technical field of thrust measurement, in particular to a thrust measurement fixed frame of an engine test bench and a thrust measurement bench thereof. Background technique [0002] Engine testing and testing technology is an important part of solid propulsion technology, and thrust measurement is an important parameter that needs to be measured in engine testing and testing. To study engine thrust, a large number of repeated experiments are required, and it is impossible to put all these experiments into flight tests. The main reason is that the flight test has high cost, long period, small amount of information harvested, risky, and requires a lot of manpower. This requires the ground test of the engine. The ground test of the engine refers to the static test of the system on the ground according to specific conditions and environmental requirements, and obtains information describing various performance indicators of t...
