Embodiment

[0046] For small and medium UAVs in active service, rocket-assisted zero-length launches are the most widely used. Rocket boost launch is an important link in the flight process of UAV. 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, and the stability of the UAV during take-off is determined by the pitch angle of the body. The measurement accuracy of the thrust line is the key factor for the success of the UAV launch.

[0047] At present, the thrust line of the UAV that uses rocket-assisted zero-length launch is basically measured by hanging. The hanging of the drone is realized by connecting the hanging equipment installed at the contact point betwee...

Abstract

The application provides a thrust line measuring boom, a device and an unmanned aerial vehicle thrust line measuring system, which belong to the field of aviation technology. The thrust line measuring device includes a suspension ring, a base component, a first adjusting component, a second adjusting component and a measuring component. When in use, the rocket cone and the measuring tube constitute the use environment of the boom body, wherein the rocket cone is connected with the mounting bolts, and the measuring tube is used to measure the thrust line. The reliable installation of the boom body is realized through the connection of the installation bolts. The first cross joint and the second cross joint can ensure the reliable rotation of the boom body in the measurement plane, and ensure that the center of gravity of the UAV passes through the center line of the boom body. The radial deformation of the main body can be ignored when the aircraft is hung, which improves the measurement accuracy.

Description

technical field [0001] The present application relates to the field of aviation technology, in particular, to a thrust line measurement boom, a device and a thrust line measurement system for an unmanned aerial vehicle. Background technique [0002] Rocket boost launch is an important link in the flight process of UAV. 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, and the stability of the UAV during take-off is determined by the pitch angle of the body. The measurement accuracy of the thrust line is the key factor for the success of the UAV launch. [0003] At present, the thrust line of the UAV that uses rocket-assisted zero-length launch is basi...
