CASING OPENING/CLOSING SYSTEM OF AN UNMANNED HELICOPTER

摘要

A casing opening/closing system of an unmanned helicopter, the unmanned helicopter includes a casing, a motor, a rotor wing and a tail pipe; one end of the motor and one end of the tail pipe are mounted in the casing; the casing opening/closing system includes: a hatch arranged on the upper part of the casing, an opening/closing cover arranged on the hatch and a retractable device; the opening/closing cover is articulated with the casing by means of a hinge, the retractable device is mounted in the casing and is connected with the opening/closing cover for controlling the opening/closing cover to open and close the hatch. Compressed underspin airflow rotating at the rotor wing at high speed is introduced into the casing through the hatch arranged on the upper part of the casing by the casing opening/closing system of an unmanned helicopter, heat in the casing is directly removed by underspin airflow, with high heat emission efficiency, cooling down the motor in the casing.
