Nonstationary flow dynamic characteristic, increase the stalling angle of blade so that cycloid propeller have it is high-efficient, noise is low, vectored thrust become
Change the features such as fast.
The Chinese patent of Publication No. CN103434627A discloses the pendulum using a kind of rocker arm sliding block as control mechanism
Line paddle.The purpose of the invention is the reliability for avoiding trying to improve mechanism using conventional cam mechanism and the mechanical effect of raising
Rate, the control mechanism in the patent be by using in mechanism the fixed upright bar of inner ring and transmitting lateral displacement；In sliding block drives
Ring lateral displacement makes blade obtain deflection angle, and inner ring, which circumferentially rotates, makes blade obtain phase angle, the cycloid propeller control in the patent
Mechanism is relative complex, while overall mechanism is huge, heavy, is only applicable to study cycloid propeller aerodynamic characteristic as experiment porch, no
It is suitble to aircraft.
By the United States Patent (USP) NO.6/939 of valley western work great Hu et al. application, 888 (publication number GB939888 (A)) are mentioned
It is a kind of to control vertical axis propeller eccentric circle mechanism using pitch.The mechanism controls the inclination angle of side plate and a series of by steering engine
Link transmission, to realize the control to blade pitch angles.The control mechanism has the response that is exceedingly fast, lighter weight, and at
Function applies to miniature cycloid propeller unmanned plane.But the solution is more due to contacting between component, causes mechanical loss larger.
Currently, cycloid propeller is typically designed as single cycloid propeller, if the coaxial design thought of coaxal helicopter is applied to pendulum
