Description

technical field [0001] The invention relates to a device for adjusting the center of gravity of a remote-controlled aircraft, in particular to a device for adjusting the center of gravity of a remote-controlled aircraft for real-time measurement and adjustment of the center of gravity of the remote-controlled aircraft. Background technique [0002] The position of the center of gravity of the aircraft seriously affects its balance, controllability and safety. Therefore, advanced aircraft such as airplanes and helicopters are equipped with a center of gravity measuring device that can monitor the position of the center of gravity in real time, and even have a device that can actively adjust the position of the center of gravity. Center of gravity adjustment device. However, model remote-controlled aircraft such as remote-controlled aircraft or remote-controlled helicopters cannot be equipped with the center of gravity measuring device on the fuselage due to cost and weight co...

Problems solved by technology

Compared with the bracket-type center-of-gravity measuring device, it is easier to measure the position of the center of gravity of the fuselage by using the suspension-type center-of-gravity measuring device for larger-sized remote-controlled aircraft, and the center of gravity adjustment does not need to take off the fuselage. However, it is still too troublesome to hang the remote control aircraft every time the center of gravity is measured and adjusted.

In addition, the suspended center of gravity measuring device must be set and fixed at a sufficient height to suspend the remote control aircraft. Therefore, the suspended center of gravity measuring device cannot be carried to the flying field for use, causing users When you want to adjust the center of gravity of the fuselage outdoors in response to wind direction, gust strength or humidity, there is still no ideal equipment to use

[0005] Furthermore, whether it is a bracket-type center-of-gravity measuring device or a suspension-type center-of-gravity measuring device, it can only measure the position of the center of gravity of the remote control aircraft on a single axis.

In detail, the direction along which the remote-controlled aircraft extends along its fuselage is a longitudinal axis (longitudinal axis). The known center-of-gravity measuring device of the remote-controlled aircraft can only measure the position of the center of gravity in the direction of the longitudinal axis. The position of the center of gravity on the longitudinal axis affects the stability of its pitch (Pitch) control; however, the remote control aircraft is perpendicular to the longitudinal axis and extends along its wings as a lateral axis (Lateral axis). The position of the center of gravity of the remote control aircraft will affect the stability of the roll (Roll) control of the remote control aircraft, but the known center of gravity measurement device of the remote control aircraft cannot measure the position of the center of gravity on the horizontal axis, so that remote control aircraft players often can only use Visually roughly balance the weight on both sides of the wing, resulting in poor center of gravity adjustment accuracy
