Shell opening and closing system of unmanned helicopter

Abstract

A casing opening and closing system for an unmanned helicopter. The unmanned helicopter includes a casing, a motor, a rotor, and a tailpipe. Both the motor and the tailpipe are installed in the casing. The casing opening and closing system includes a The hatch on the upper part of the casing, the opening and closing cover installed on the hatch, the retractor, the opening and closing cover is connected with the casing through a hinge, the retracting device is installed in the casing, and is connected with the opening and closing cover to control the opening of the opening and closing cover and close the hatch. The casing opening and closing system of the unmanned helicopter uses the hatch on the upper part of the casing to introduce the downswirling airflow compressed by the high-speed rotation of the rotor into the casing, and directly uses the downswirling airflow to take away the heat in the casing, with high heat dissipation efficiency , so that the motor located in the casing cools down quickly, reduces the failure rate of the motor, reduces the possibility of the crash of the unmanned helicopter, and avoids unnecessary economic losses.

Description

technical field [0001] The invention relates to the technical field of unmanned helicopters, in particular to a casing opening and closing system of an unmanned helicopter. Background technique [0002] Due to its strong weather adaptability, unmanned rotor helicopters are widely used in civil and military fields for operations such as aerial photography, high-altitude overhead lines, and line inspections. Under such circumstances, it needs to hover for a long time, and the unmanned helicopter cannot rely on high-speed movement for natural air cooling, and the internal temperature rises, which may easily cause the engine to overheat and cause failure, and even cause the crash of the unmanned helicopter, resulting in huge economic losses. [0003] The previous patent "Unmanned Helicopter with Engine Cooling Cover" Application No.: 201310635702.2 Although the above technical problems have been solved to a certain extent, there are still major defects. Only the heat dissipation...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the current unmanned helicopter cooling device, the heat dissipation efficiency is low, the engine temperature drops slowly, and the failure rate is still high, etc., and a casing opening and closing system for unmanned helicopters is designed.
