Abstract

The invention discloses a front-rear rotary type flapping wing paddle. The front-rear rotary type flapping wing paddle comprises a paddle frame and at least two paddle blades, the paddle blades are rotatably connected to the paddle frame through blade shafts, a center shaft of the paddle frame is connected with an output shaft of a power device in a transmission mode, the paddle blades are drivenby the power device to rotate along with the paddle frame, one ends of the blade shafts extend outside the paddle frame and are hinged to an output end of a transmission assembly, an input end of thetransmission assembly is connected with the output end of the power device in a transmission mode, and the transmission assembly is used for keeping the front edges of the paddle blades to always point forward. The problem that the efficiency of rotor wing paddles in the prior art is low is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of propellers, and more specifically, the present invention relates to a forward and backward rotating flapping propeller. Background technique [0002] Nowadays, ships and aircrafts of various sizes mostly adopt the mode of propeller rotation propulsion to obtain propulsion power. The efficiency of the propeller is not high, and part of the energy is wasted on the resistance of the propeller rotation. When the speed is extremely high, its propulsion efficiency will decrease instead, and the hydrodynamic noise of the propeller is very loud. Many fields have to reduce the propeller Speed ​​and propulsion capacity to reduce the noise generated during propulsion. Therefore, the current research on bionic propulsion technology has received extensive attention. The main problem is that it is difficult to generate sufficient propulsion. The main reason is that the rigid structure and movement mode are difficult t...
