Embodiment

[0025] Example: see Figure 4 , Figure 5 .

[0026] A thrust line correction method for an unmanned aerial vehicle using centroid reckoning, comprising the following steps:

[0027] a. The horizontal direction of the unmanned aerial vehicle 1 that has been assembled is fixed, and a center of mass measurement platform 5 is designed in this embodiment, the unmanned aerial vehicle that is assembled is fixed horizontally on the measurement platform, and the rocket booster is installed on the measurement platform side of

[0028] b. Measure the center of mass of the drone when placed horizontally;

[0029] This embodiment adopts such a method: as figure 2 As shown, three load cells are set on the measuring platform, that is, the first sensor 6, the second sensor 7, and the third sensor 8. The coordinate system OXYZ is the coordinate axis of the drone, and the coordinate system O'X'Y' is the measurement coordinate system on stage, is the vertical distance between th...

Abstract

The invention relates to the technical field of testing a launching system of an unmanned aerial vehicle, and particularly relates to a method for correcting a thrust line of an unmanned aerial vehicle by adopting centroid computation. The method comprises the following steps of a. well fixing the finally assembled unmanned aerial vehicle in horizontal direction, and installing a rocket booster at one side of an unmanned aerial vehicle body; b. measuring the centroid of the unmanned aerial vehicle which is horizontally placed; c. determining a connecting line between the centroid of the aerial vehicle and the installing fulcrum of a thrust seat of a rocket launcher as a straight line where the thrust line is; d. according to the computed thrust line, regulating the mounting angle of the thrust seat of the rocket booster so as to enable the axis of the rocket launcher and the thrust line to be coincided; e. installing the aerial vehicle with a well regulated thrust seat angle on the rocket booster. The method has the beneficial effects that the method is applicable to unmanned aerial vehicles with larger size and weight; when the unmanned aerial vehicle is under a non-filled-with-oil state, the thrust line of the unmanned aerial vehicle, measured by adopting the scheme, is closer to the practical thrust line of the unmanned aerial vehicle in launching compared with a suspension method, and the zero-length launching success rate of the unmanned aerial vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of UAV launch system testing, in particular to a UAV thrust line correction method using centroid calculation. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. One of the ways for drones to take off is to use booster rockets to launch into the air, which are widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic jamming, etc. [0003] The launch system is an important functional system of UAVs, and it is a necessary technical guarantee to meet the various needs of UAVs such as flexibility, reusability, and high survivability. The rocket booster accelerates the UAV to a certain speed and height in a short period of time. It has the advantages...
