Abstract

The invention discloses a land-space amphibious rotor craft capable of omnidirectional rolling on the ground, and an installation and control method for the land and-space amphibious rotor craft, and belongs to the technical field of aircrafts. The rotor craft is provided with a flight control system and a power system, and the flight control system consists of a rotor wing rack and a main controller. The power system employs a lithium battery as a power supply. The periphery of an omnidirectional rolling mechanism is presented as a spherical support structure. A spherical support is a big circular guide rail, and an aircraft passes through a straight rod passing through the center. Two ends of the straight rod are respectively provided with a pulley, and the pulleys are embedded into the big circular guide rail. The pulleys employ rolling bearings. Aiming at a problem that a rotor craft is liable to be damaged in the prior art and a problem that a rotor craft is liable to be damaged in the prior art during collision and landing, the rotor craft can drive the spherical support to make omnidirectional rolling motion on the ground, and the spherical support structure protects the rotor craft.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a land-air amphibious rotor aircraft that can roll omnidirectionally on the ground and its installation and control method. Background technique [0002] Rotorcraft has the characteristics of strong maneuverability and flexibility, but its motion efficiency is not high due to the need to maintain the flight state. At the same time, the rotor has extremely high requirements for system stability, and is prone to damage during collisions and landings. The existing tripods and protective rings cannot provide all-round protection, and the rotorcraft is prone to tip over after landing and impact, causing secondary damage. [0003] Chinese invention patent, publication number: CN105539037A, publication date: May 4, 2016, discloses a ground-air four-rotor unmanned aerial vehicle capable of rolling on the ground, belonging to the technical field of four-rotor unmanned aerial vehicles, in...
