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 force measurement mounting frame. The mounting frame is characterized by including an engine mounting top frame, a left upright column and a right upright column with the same structure, a front joint and a rear joint. Bottom surfaces of the left upright column and the right upright column are connected with a moving frame in a detachable manner.The engine mounting top frame is fixedly connected with top surfaces of the left upright column and the right upright column to form a gantry shape. The front joint and the rear joint are mounted onthe engine mounting top frame in a detachable manner. Mounting holes used for mounting the front joint and the rear joint are arranged on the engine mounting top frame. According to the engine test bench thrust force measurement mounting frame of the invention, the gantry-type engine mounting frame is adopted, an engine is arranged in a suspended manner, measurement accuracy of engine thrust forceis improved, positions of the front joint and the rear joint are arranged to be adjustable, an applicable range of the engine mounting frame is greatly improved, and the problem that in the past, oneengine is provided with one engine mounting frame is solved.
Description
technical field [0001] The invention relates to the technical field of thrust measurement, in particular to a thrust measurement installation frame of an engine test bench and a thrust measurement platform 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 indic...
