Problems solved by technology

[0002] It can be said that the research on cycloidal propellers has been going on for a long time, and relevant researchers at home and abroad are even more obsessed with applying it to the power plant of future aircraft. However, due to the aerodynamic force generated by the cycloidal propeller blades when they rotate It is a complex unsteady process, so researchers at home and abroad have never had a mature analysis method, and the whole research has always been in the exploratory stage

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown in -3, the coaxial cycloid propeller aircraft of the present invention includes a fuselage, a rudder system, a power plant, an energy system, and a control system. The fuselage is a spherical frame composed of a transverse frame 6 and eight semicircular longitudinal frames 8, and the angle between the longitudinal frames 8 is 45°. The longitudinal frame 8 and the transverse frame 6 are made of carbon fiber composite material, so that the fuselage has the advantages of light weight and high strength.

[0023] The rudder surface system is located on the upper side of the fuselage, and includes No. 1 rudder surface 2 whose span direction is perpendicular to the cycloidal propeller axis and No. 2 rudder surface 3 whose span direction is parallel to the cycloidal propeller axis. There are four rudder surfaces in t...

Abstract

The invention belongs to the technical field of unmanned aerial vehicle structural design and particularly relates to a coaxial cycloid paddle aircraft. A fuselage is a spherical framework composed of a transverse framework and eight semicircular longitudinal frameworks. A control surface system is located on the upper portion in the fuselage and comprises two sets of first control surface and two sets of second control surfaces, the number of the control surfaces is four, the extending direction of the first control surfaces is perpendicular to rotary shafts of cycloid paddles, the extending direction of the second control surfaces is parallel to the rotary shafts of the cycloid paddles, the cycloid paddles are located in the transverse framework, the two cycloid paddles are coaxially arranged, and a propeller is located in the middle of the control surface system. An energy system is located at the bottom end in the fuselage. A control system is composed of control sub-systems symmetrically arranged in the transverse framework, and each control sub-system controls the rotation speed of the corresponding adjacent cycloid paddle and also controls the attack angle of the corresponding control surface. The cycloid paddles are combined with the propeller, and noise is low.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle structure design, and in particular relates to a coaxial cycloid propeller aircraft. Background technique [0002] It can be said that the research on cycloidal propellers has been going on for a long time, and relevant researchers at home and abroad are even more obsessed with applying it to the power plant of future aircraft. However, due to the aerodynamic force generated by the cycloidal propeller blades when they rotate It is a complex unsteady process, so researchers at home and abroad have not had mature analysis methods, and the whole research has always been in the exploratory stage. However, the cycloidal propeller can generate 360-degree full vector thrust as required, and the cycloidal propeller has a higher thrust level than the conventional propeller and turbine engine. There are many installation methods of the cycloidal propeller to replace the conventional aircraft...
