Thrust line measurement suspender, device and unmanned aerial vehicle thrust line measurement system

Abstract

The invention provides a thrust line measurement suspender, a thrust line measurement device and an unmanned aerial vehicle thrust line measurement system and belongs to the technical field of aviation. The thrust line measurement device comprises a hanging ring, a base assembly, a first adjusting assembly, a second adjusting assembly and a measuring assembly. During use, a rocket cone seat and ameasuring cylinder form the use environment of a suspender body, wherein the rocket cone seat is connected with a mounting bolt, and the measuring cylinder is used for measuring a thrust line. The reliable installation of the suspender body is achieved through the connection of the mounting bolt; a first cross joint and a second cross joint can guarantee the reliable rotation of the suspender bodyin a measurement plane, so that it is guaranteed that the gravity center of the unmanned aerial vehicle passes through the center line of the suspender body; the radial deformation of the suspender body can be ignored when the suspender body hangs the aircraft, and therefore, measurement precision is improved.

Description

technical field [0001] The present application relates to the field of aviation technology, and in particular, to a thrust line measuring boom, a device and a UAV thrust line measuring system. Background technique [0002] Rocket-assisted launch is an important part of the UAV's flight process. The UAV relies on its own power and the thrust generated by the rocket booster to accelerate from a static state to a safe flight speed and altitude. After the rocket booster is separated, there is no The man-machine enters the flight route under the action of its own power. The speed of the UAV during take-off is determined by the thrust of the booster rocket and the engine. The stability of the take-off process is determined by the pitch angle of the body. The measurement accuracy of the thrust line is the key factor for the successful launch of the UAV. [0003] At present, the thrust line of rocket-assisted zero-length launch drones is basically measured by hanging. UAV hoisting...
