A cycloidal propeller aircraft
By decoupling the blade rotation motion through an independent transmission system, the problem of low propulsion efficiency in cycloidal propeller aircraft is solved, achieving a high-efficiency combination of lift and propulsion, suitable for stable transitions in various flight conditions.

Abstract
The present application relates to a kind of cycloidal propeller aircraft, including propeller, fuselage, cycloidal propeller, tail and landing gear, the cycloidal propeller includes main shaft, pull rod, blade shaft and blade, main shaft can drive pull rod, blade shaft and blade rotate around main shaft axis, pull rod is fixedly connected with main shaft, blade shaft is freely rotatable relative to pull rod, pull rod supports blade shaft, blade shaft and blade are fixedly connected, the number of blade is not less than two, each blade has an independent transmission system, each transmission system drives corresponding single blade to rotate around the axis of the blade shaft, the rotation of all blades around the axis of the blade shaft is not associated;The cycloidal propeller aircraft of the present application is simple in structure, blade acts as fixed wing when normal forward flight, no dead weight;In the transition state of take-off and landing, cycloidal propeller gradually accelerates and decelerates, provides suitable lift.
