The invention provides a small unmanned helicopter fuselage which comprises a fuselage ring, a starting system, a drive system, an engine and an exhaust pipe, wherein the drive system comprises a gear speed clutch, a gear box power synchronous belt, a gear box power gear, a gear box driven gear, a driven gear synchronous belt, a tail shaft power gear and a tail pipe drive system, wherein the side of the gear speed clutch is provided with a gear which is connected with the gear box power gear through the gear box power synchronous belt; the gear box driven gear is connected with the tail shaft power gear through the driven gear synchronous belt; and the tail shaft power gear is connected with the tail pipe drive system. According to the small unmanned helicopter fuselage, the unique fuselage ring structure has high rigidity and small useless space in the fuselage, and the front and rear parts of the fuselage ring have bending to enable two ends of the fuselage to be contracted so as to facilitate manufacturing of the housing of the streamline fuselage; the built-in starting system can control starting remotely; and the improved drive system shortens the power drive distance, has small load and greatly improves the transmission efficiency.
Description
technical field [0001] The invention relates to a small unmanned helicopter fuselage, which belongs to the field of mechanical structures. Background technique [0002] The unmanned helicopter is fully automatically controlled by computers and microprocessors, and can be operated with human hands on the computer, which is convenient and safe. The small unmanned helicopter itself has strong weather adaptability and can fly under conditions that are not suitable for ordinary aircraft. It is small in size and high in precision. More than anything. Small unmanned helicopters have high flight stability, strong positioning, and low environmental site requirements. When used in pesticide spraying, the spraying efficiency is 10 times that of manual spraying; when used in high-altitude vertical aerial photography, the definition is higher In addition, small unmanned helicopters can also perform long-range aerial photography and stunt photography, forming a new aerial photography sy...
