Oil and power mixed small unmanned helicopter and its power principle

Abstract

The invention provides a power principle of a small unmanned helicopter. Power sources of a primary rotor and a tail rotor are separately arranged to realize the relative driving independence of the primary rotor and the tail rotor in order to reduce a power transmission mechanism required by the respective driving of the primary rotor and the tail rotor by single power sources. The invention also provides an oil and power mixed small unmanned helicopter based on the principle. The oil and power mixed small unmanned helicopter comprises a fuselage frame and a tail tube, the tail tube is connected to the rear end of the fuselage frame, the oil and power mixed small unmanned helicopter also comprises an oil tank, an external battery and a small motor, the oil tank is installed on the side surface of the fuselage frame, the external battery is installed on the tail tube, and the small motor is installed at the tail end of the tail tube and is connected with the tail rotor. The oil and power mixed small unmanned helicopter combining an oil driving mode with an electric driving mode has the advantages of reduction of mechanical mechanisms, reduction of the failure rate, strong cruising ability, large carrying ability and high work efficiency.

Description

technical field [0001] The invention relates to an oil-electric hybrid small unmanned helicopter, which belongs to the field of small unmanned aerial vehicles. Background technique [0002] Traditional small unmanned helicopters are divided into two types: oil-driven and electric, both of which have deficiencies. Oil-operated small unmanned helicopters require a transmission mechanism to control the tail, and the mechanical structure is complex and prone to failure. The electric small unmanned helicopter consumes a lot of power, has a small load capacity, and needs to complete the operation tasks many times, so the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an oil-electric hybrid small unmanned helicopter, which combines oil-driven and electric drive modes, has low failure rate, strong endurance and large load capacity . [0004] In order to solve the p...
