Double-layer propeller multi-degree-of-freedom quadcopter

Abstract

The invention discloses a double-layer propeller type multi-degree-of-freedom four-axis aircraft in the field of measurement equipment. A double-layer propeller structure is positioned at the top of each engine compartment; a vertical rotation control mechanism is arranged on the side surface of each engine compartment and is connected with the output end of a connecting rod; a cam is controlled to rotate by a starting motor and acts on a steering control structure which is arranged in the middle of a main aircraft body; the steering control structure rotates and drives a steering motor at the bottom of the steering control structure; the steering motor is respectively connected with the input end of each connecting rod to enable each engine compartment and the corresponding double-layer propeller structure to freely rotate in a horizontal plane. According to the double-layer propeller type multi-degree-of-freedom four-axis aircraft, the characteristic that the flight attitude of the whole aircraft is highly flexible can be realized, so that requirements on the flight attitude of the aircraft under the condition of complex terrain are met.

Description

technical field [0001] The invention relates to a device in the field of measuring equipment, in particular to a double-layer propeller-type multi-degree-of-freedom four-axis aircraft. Background technique [0002] Quadcopter is a common form of multi-axis aircraft in small aircraft. Because of its dexterity and maneuverability, it is widely used in low-altitude aerial photography, disaster area exploration and other flight missions under complex terrain conditions. The ability of quadcopters to perform flight tasks under complex terrain conditions is calibrated by the flight actions that can be performed during the flight process. The air flight attitude of conventional quadcopters mostly needs to keep the fuselage close to the level as a whole, with low degrees of freedom. The operability is small. [0003] After searching the prior art, it was found that Chinese patent document number CN101914893, published on December 15, 2010, records a bridge detection robot based on ...

AI Technical Summary

Problems solved by technology

Due to the horizontal flight attitude of its fuselage, this type of aircraft cannot pass through a slit with a width smaller than the width of the fuselage itself, and its flexibility is not high under complex and dangerous terrain conditions, and the torque generated by a single propeller can easily cause the fuselage to rotate
