Abstract

The invention belongs to the technical field of propellers and particularly relates to an integrated amphibian propeller. The integrated amphibian propeller comprises a duct, a propeller, a frame, a high-speed motor, an overrunning clutch and a low-speed motor, and the propeller, the frame, the high-speed motor, the overrunning clutch and the low-speed motor are arranged in the duct. The high-speed motor and the low-speed motor are mounted in the duct through the frame; the low-speed motor is connected with the high-speed motor through the overrunning clutch; the propeller is positioned at thefront end of the duct and arranged on an output shaft of the high-speed motor; front and rear ends of the duct are provided with a front flow guide cover and a rear flow guide cover. The integrated amphibian propeller is variable in output torque and rotating speed, realizes underwater and aerial propelling functions and has advantages of compact structure, light weight, high reliability and thelike.

Description

technical field [0001] The invention belongs to the technical field of thrusters, in particular to an integrated water-air dual-purpose thruster. Background technique [0002] The water-air amphibious cross-domain vehicle is a new concept vehicle that can sail in the underwater environment and fly in the air, which can greatly expand the scope of operation and application fields. In order to realize the navigation function of the water-air amphibious cross-domain vehicle in the two media of water and air, propellers that can realize the functions of underwater and air operations are needed. However, due to the different medium properties of water and air, the corresponding thruster design concepts are also quite different. For example, under the same propeller size and rotational speed, the torque in water is much greater than that in air. It can be seen that the propulsion device in the air is characterized by low torque and high speed output, while the propulsion device ...
