Problems solved by technology
[0003] The parameters of small thrust engines, such as power consumption, fuel consumption, thrust, dynamic characteristics, axial reaction torque, speed, power, etc., are important parameters for designing aircraft. The test system mainly tests the static thrust parameters of the small thrust engine. The current and thrust are displayed through the digital tube. The test parameters are few, and the curve display and recording of historical data cannot be performed, and the dynamic characteristics cannot be tested.

Embodiment Construction
[0019] The present invention is a kind of small thrust engine parameter test system, in conjunction with accompanying drawing, describe in detail as follows:
[0020] There are many types of small thrust engines involved in the present invention, such as jet engines, turbofan engines, and propeller engines. This embodiment uses electric propeller small thrust engines as examples for illustration. The small thrust engine to be tested is a brushless DC motor with a diameter of 40mm, a length of 50mm, and a maximum power of 1440W. A four-bladed propeller with a diameter of 144mm is fixed on the main shaft. The present invention can also be used for the test of small jet, turbofan, ducted fan and fuel type thrust engine after adding, subtracting and replacing certain detectors and adjusting the built-in sampling program.
[0021] Small thrust engine parameter test system structure of the present invention is as figure 1 As shown, the system includes three subsystems, that is, the...

The parameter testing system for the small-sized thrust engine to be tested can be used for omnibearing parameter measurement of the small-sized thrust engine.
Description
technical field [0001] The invention belongs to the technical field of automatic detection devices, and mainly relates to the structural design of a test device for working parameters of a small thrust engine. Background technique [0002] Small thrust engine is a kind of small thrust device, often used as a power device for small aircraft or model aircraft. [0003] The parameters of small thrust engines, such as power consumption, fuel consumption, thrust, dynamic characteristics, axial reaction torque, speed, power, etc., are important parameters for designing aircraft. The test system mainly tests the static thrust parameters of the small thrust engine. The current and thrust are displayed through the digital tube. The test parameters are few, and the curve display and recording of historical data cannot be performed, and the dynamic characteristics cannot be tested. Therefore need a kind of test device to be able to test the operation parameter of small thrust engine c...
