Title:
TAIL GAS BALANCE SYSTEM OF UNMANNED HELICOPTER
Document Type and Number:
WIPO Patent Application WO/2016/000486
Kind Code:
A1
Abstract:
A tail gas balance system of an unmanned helicopter. The unmanned helicopter comprises a fuselage, an engine, a rotor wing, a parachute device and a tail pipe. The parachute device is mounted on the rotor wing head of the rotor wing. A carrying device is mounted on the nose of the fuselage. The tail gas balance system comprises an exhaust pipe. The exhaust pipe is mounted on the rear portion of the fuselage and connected with the engine. The exhaust outlet of the exhaust pipe faces right downwards. A gravity center adjusting device is further mounted in the fuselage. Since the exhaust outlet of the exhaust pipe of the tail gas balance system faces right downwards, corresponding carrying capacity can be increased as long as lift force is increased. Meanwhile, insofar as the arrangement of counter weight bags in the gravity center adjusting device is adjusted in the fuselage, the center of the unmanned helicopter moves backwards to balance the lift force generated by tail gas, and then the balance of the unmanned helicopter in normal operation is guaranteed. When accidents happen during the flying of the unmanned helicopter, the back-moved gravity center enables the tail of the unmanned helicopter to incline downwards and the nose to lift up, hence, the tail pipe of the unmanned helicopter lands firstly, and the impact during landing is buffered. Damage to the carrying device located on the nose is prevented, unnecessary economic loss is avoided, and risk cost of unmanned helicopter operation is reduced.
