A test device for ducted fan engine

Abstract

The invention provides a ducted fan engine testing device, which comprises a tensile force testing module and a torsion measurement module, wherein the two modules work independently and connect mutually and do not interfere with each other, therefore, not only can the testing on the tensile force of the ducted fan be realized, but also the testing on the torque can be realized. By adopting hydraulic pressure as a middle load transmission mode, the balance action can be effectively realized, so that the errors of two installing ends of a ducted fan engine caused by asymmetrical installation can be eliminated, the accurate output of tested electric signals can be further realized, accurate measurement on the tensile force and torque can be realized, and therefore, the device has a smart structure, is convenient and simple to use, and has good testing performances.

Description

technical field [0001] The invention provides a test device for a ducted fan engine, which belongs to the field of equipment design for the test of a ducted fan engine. Background technique [0002] Due to its unique dynamic characteristics, ducted fan engines are increasingly used in technical fields such as unmanned aerial vehicles and unmanned vehicles. For a good ducted fan engine, we need to know its important dynamic parameters. And use it to guide the use and debugging of the ducted fan engine. In terms of its important power parameters, pulling force or thrust has always been an important parameter, and as the power of the ducted fan engine is getting higher and higher, the power is getting stronger and stronger, and the torque generated is also getting bigger and bigger. For this reason its torque is also an important parameter to be tested in the future. [0003] At present, the test equipment for ducted fan engines is generally limited to simple tension gauges, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the test equipment for ducted fan engines is generally limited to simple tension gauges, and some even directly use hand-held tests. The test requirements are extremely simple, so no useful parameters can be obtained at all, and hand-held is even more potential. The danger of exploding oars and hurting hands has never been tested for torque; there is also some simple equipment in the process of testing tension, the structural design is not very reasonable, resulting in large measurement errors, and the actual value of the parameters is not very good. inferred
