Coaxial twin-rotor ducted aircraft

Abstract

The invention relates to a coaxial double-rotor ducted aircraft, which solves the problems of poor high-speed flight capability and complex structure of ordinary rotorcraft. The upper bracket and the lower bracket are connected by a support plate to form a whole machine bracket, and have an airfoil duct body Around the support, the landing gear is installed on the periphery of the lower support, the motor power supply is installed on the upper part of the upper support, and the coaxial motor composed of two motors of the same type is installed in the center of the upper support. The propeller is fixed on the propeller shaft of the motor. The two propellers are of the same type. The direction of rotation of the propellers is opposite, the lower bracket is equipped with the lower central body, the upper layer of the lower central body is equipped with the attitude reference system, the middle layer is equipped with the power supply of the flight control system, the lower layer is equipped with the flight control board, and the inner circumference of the lower bracket is equidistantly installed. The steering gear is connected to the control panel through the control panel linkage. The invention has hovering, low-speed and high-speed flight capabilities, can take off and land vertically, has strong adaptability, good concealment, compact structure and wide application range.

Description

technical field [0001] The invention relates to an aircraft, in particular to a coaxial dual-rotor ducted aircraft capable of vertical take-off and landing, hovering and high-speed flight, and belongs to the field of aircraft design. Background technique [0002] In modern warfare, it has become a recognized fact that mastering battlefield information means mastering the initiative of war. How to quickly obtain battlefield information has become a research hotspot all over the world. A commonly used method is to use unmanned aerial vehicles. This kind of aircraft needs to have rapid response and maneuverability, can arrive at the designated place in the first time, and can realize information collection stably. It also needs good adaptability. Working in a variety of complex environments requires concealment to obtain information continuously. Countries all over the world have conducted in-depth research in the field of unmanned aerial vehicles in order to obtain a fast, fl...

AI Technical Summary

Problems solved by technology

Fixed-wing aircraft fly faster, but cannot hover, and take-off and landing have relatively high environmental requirements; rotorcraft can take off and land vertically, and have hovering capabilities, but they lack high-speed flight capabilities, and only emphasize hovering and low-speed flight capabilities. The propeller of the rotorcraft is easy to damage the aircraft due to the lack of protective devices
