Coaxial propeller power system, coaxial double-propeller underwater propeller and aircraft

Abstract

The invention provides a coaxial propeller power system, a coaxial double-propeller underwater propeller and an aircraft, relates to the technical field of underwater propellers, and solves the problem that an existing underwater propeller is not provided with a coaxial double-propeller power system. The coaxial propeller power system comprises a first paddle driving system and a second paddle driving system; the first paddle driving system comprises an upstream driving motor and a first paddle which are coaxially arranged, and the upstream driving motor is in transmission connection with thefirst paddle; the second paddle driving system comprises a downstream driving motor and a second paddle which are coaxially arranged, and the downstream driving motor is in transmission connection with the second paddle; the upstream driving motor and the downstream driving motor are coaxially arranged and fixedly connected. The underwater propeller and the aircraft both adopt the coaxial propeller power system, spinning of the propeller in the rotating direction of the blades can be counteracted, and better thrust is obtained while high motion precision and more stable postures are achieved.

Description

technical field [0001] The invention relates to the technical field of underwater propellers, in particular to a coaxial propeller power system, a coaxial double-blade underwater propeller and a coaxial double-blade aircraft using the coaxial propeller power system. Background technique [0002] The propeller is the core component of current underwater equipment, including underwater robots and underwater power-assisted equipment. The performance of the propeller is directly related to the motion performance of the equipment. [0003] The propeller is mainly composed of three or more blades, a motor and a drive circuit, a flow channel and a casing. Since the propulsion is generated by the motor driving the blades to rotate and cut water, a torque in the same direction as the rotation direction of the blades will be generated during the rotation of the motor. In continuous operation, this torque will force the propeller to automatically rotate along the direction of blade rot...

AI Technical Summary

Problems solved by technology

For propellers such as airplanes running in the air, the transmission structure can be effectively maintained and replaced in the air, so the structure can be more complex

However, if this set of technology is used directly or slightly improved for underwater propulsion, then for underwater equipment, the overweight mechanical transmission structure will cause a large amount of buoyancy loss, and usually metal structures must be used in seawater environments. Strict anti-corrosion, it is doomed that this solution cannot be directly applied to underwater equipment
