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

Abstract

The invention discloses an engine thrust measuring stand. The Engine thrust measuring stand comprises a fixed frame, a movable frame and a loading measuring device; the loading measuring device comprises a spring piece, a loading mechanism and a work force sensor; the movable frame is hung on the fixed frame; the loading mechanism is fixedly mounted on the fixed frame; and two ends of the work force sensor are respectively connected with the fixed frame and the movable frame. According to the engine thrust measuring stand and a measuring method disclosed by the invention, the measurement of engine thrust is realized; and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of thrust measurement, in particular to an engine thrust measurement stand and a method for using the same. Background technique [0002] Engine test and test technology is an important part of solid propulsion technology, and thrust measurement is an important parameter to be measured in engine test and test. To study engine thrust requires a lot of trial and error, all of which would be impossible to put into flight tests. The main reason is the high cost of flight test, long cycle, small amount of information harvest, risky, and need to consume 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 to obtain information describing the performance indicators of the system, so as to solve the key problems in the engine thrust test process. However, in...
