Novel coaxial double-rotary double-degree-of-freedom eight-rotor-wing amphibious aircraft

Abstract

The invention provides a novel coaxial double-rotary double-degree-of-freedom eight-rotor-wing amphibious aircraft. The novel coaxial double-rotary double-degree-of-freedom eight-rotor-wing amphibious aircraft is characterized in that four supporting arms are vertical to one another on the same plane; one ends of the four supporting arms are connected with the periphery of an aircraft body and the other ends of the four supporting arms are provided with coaxial double-rotary rotors by double-degree-of-freedom gyro mechanisms; an undercarriage is connected to the aircraft body; an electric control system is arranged in the aircraft body and is used for controlling a double-degree-of-freedom rack and the four coaxial double-rotary rotors According to the novel coaxial double-rotary double-degree-of-freedom eight-rotor-wing amphibious aircraft, a complicated flight task can be finished in a manner of keeping a posture of the aircraft body unchanged; on the basis of improving an onboard load, the flight is very free; various complicated flight tasks can be finished in a severe outer environment; the aircraft directly has a navigation function and supports waterborne and aerial amphibious utilization.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles (air and water), and relates to a novel structure and control coaxial dual-rotation dual-degree-of-freedom eight-rotor novel amphibious aircraft. Background technique [0002] Most of the current aircraft are fixed-wing aircraft. This aircraft cannot complete vertical take-off and landing, and needs a special runway or launching device, and its maneuverability is limited. Winged aircraft have vertical take-off and landing functions, and can also hover in the air. They have a wide range of needs in military reconnaissance, anti-terrorism, public security, fire protection, forest inspection, nuclear leak detection, and disaster relief. In particular, micro-rotor aircraft have very broad application prospects, including providing reconnaissance and surveillance in complex terrain conditions, communication relay, detection of nuclear pollution or detection in special environments, rec...

AI Technical Summary

Problems solved by technology

The lift and weight of the above-mentioned rotorcraft are relatively low, and the carrying capacity is very poor when designed as a micro-sized aircraft. The "coaxial reversing dual-rotor eight-rotor aircraft" with the patent number 201010152265.5 improves the carrying capacity to a certain extent, but its When the flight state changes, the attitude of the airframe will change, which greatly restricts its application in various fields for the inability to complete complex flight tasks in harsh battlefield environments
