Coaxial contrarotation birotor twelve-rotary wing air vehicle

Abstract

The invention provides a coaxial contrarotation birotor twelve-rotary wing air vehicle relating to the technical field of unmanned air vehicles. The air vehicle comprises an air vehicle body (1), six supporting arms (2), six birotors (3) and an electric control system (4), wherein the six supporting arms (2) are connected on the periphery of the air vehicle body (1), geometric center lines of thesix supporting arms (2) are on the same plane, and an included angle formed by the geometric center lines of two adjacent supporting arms (2) is 60 degrees; the six birotors (3) are respectively arranged at the end parts of the six supporting arms (2), and the electric control system (4) is arranged in the air vehicle body (1) to control and connect with the six birotors (3). The air vehicle has high maneuverability, and can realize vertical takeoff and landing, fast forward flight, inverted flight, hovering and change to any direction in flight; and the rotors are directly driven by an electric engine or an oil engine, thereby the energy loss of a transmission system is eliminated and the ratio of lift force to the weight of the air vehicle is increased.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to a novel-structured coaxial inversion dual-rotor twelve-rotor aircraft. Background technique [0002] UAVs have a wide range of needs in military reconnaissance, anti-terrorism, public security, fire protection, forest inspection, nuclear leak detection, and disaster relief. However, the mobility and stability of UAVs are not enough. In particular, most of the current military conflicts in the world are small-scale military conflicts on a local scale. Battles mostly take place in urban settings, especially in the increasingly fierce anti-terrorism war. The enemy's reconnaissance, surveillance and position determination And other requirements are becoming more and more important, requiring the aircraft used to have ultra-high maneuverability. [0003] UAVs can be generally divided into two categories: one is single-rotor and rotor helicopters, which roughly include ...
