Title:
FUSELAGE OPENING AND CLOSING SYSTEM OF UNMANNED HELICOPTER
Document Type and Number:
WIPO Patent Application WO/2016/000484
Kind Code:
A1
Abstract:
A fuselage opening and closing system of an unmanned helicopter. The unmanned helicopter comprises a fuselage, a motor, rotor blades and a tail pipe; one end of both the motor and the tail pipe is installed in the fuselage; the fuselage opening and closing system comprises a hatch provided on the upper portion of the fuselage, opening/closing covers installed on the hatch, and a retractable device; the opening/closing covers are connected to the fuselage via hinges; and the retractable device is installed in a housing, and is connected to the opening/closing covers to control the opening/closing covers to open and close the hatch. The fuselage opening and closing system of the unmanned helicopter utilizes the hatch provided on the upper portion of the fuselage to introduce into the fuselage downspin airflow compressed by the high-speed rotation of the rotor blades, and directly utilizes the downspin airflow to remove heat, thus having high heat dissipation efficiency, rapidly cooling the motor located in the fuselage, reducing the failure ratio of the motor and the possibility of unmanned helicopter crash, and avoiding unnecessary economic loss.
