Embodiment Construction

[0027] A vertical take-off and landing aircraft using foldable coaxial twin propellers proposed by the present invention can be divided into two parts: a cylindrical body and a coaxial twin propeller mechanism.

[0028] The coaxial double propeller mechanism includes up and down double counter-rotating motors, a foldable upper propeller and a foldable lower propeller. The upper and lower double counter-rotating motors are fixedly installed on the top of the body, and the upper and lower double counter-rotating motors are arranged coaxially along the axis of the body. The rotation direction is opposite, and the speed can be controlled independently; The propeller installation hinge is installed on the rotating shell of the propeller; the foldable upper propeller and the foldable lower propeller both adopt multiple foldable blades, the inner end of the upper propeller blade is matched with the hub head hinge, and the inner end of the lower propeller blade Cooperating with the hi...

Abstract

The invention provides a coaxial double-propeller vertical take-off and landing aircraft adopting moving core control and a control method. The aircraft comprises a machine body and a coaxial double-propeller mechanism; the machine body is of a columnar structure, and a flight control and communication device, and a task load and a power battery are contained in the machine body; and the power battery is arranged on a metamorphic core driving mechanism inside the machine body and can drive the power battery to move in the radial direction of the machine body, so that the gravity center of theaircraft is deviated from the center axis of the machine body; and the coaxial double-propeller mechanism comprises an upper and lower double-rotor motor, a foldable upper propeller and a foldable lower propeller. According to the aircraft, a propeller blade is small and portable after being folded, flight control is carried out by dynamically changing the mass center of the aircraft by adopting abuilt-in metamorphic core driving control device, no additional control device is additionally arranged outside the machine body during flight, and the flying resistance is small. The power battery is used as a moving mass of the metamorphic core without other additional weighting amount, the required operating force and torque required by mass movement are small, and the power requirement and the weight of a steering engine can be reduced.

Description

technical field [0001] The invention relates to the technical field of vertical take-off and landing drones, in particular to a vertical take-off and landing aircraft with variable center of mass control coaxial double propellers and a control method thereof. Background technique [0002] In recent years, with the development of micro-electromechanical control technology, multi-axis aircraft has been widely developed and applied because of its simple structure and low price. In order to avoid mutual interference between multiple propellers and provide sufficient control torque, the layout of the multi-axis aircraft should arrange multiple propellers driven by motors at a certain distance outward. Therefore, although the body of the aircraft is not large, but because The arms on which the motors and propellers are installed extend outwards, resulting in a larger overall volume of the aircraft, which brings great inconvenience to packaging and carrying.
