Amphibious multifunctional vertical take-off and landing aircraft

Abstract

The invention mainly provides a vertical take-off and landing aircraft with a novel framework. The vertical take-off and landing aircraft comprises a propeller, a brushless direct current motor, a steering engine, a stepping motor and a supporting base. The brushless direct current motor is connected with the propeller. The brushless direct current motor is a main power output unit and drives the propeller to rotate to provide power for the aircraft. The steering engine is connected with the brushless direct current motor and the propeller through a steering engine operating arm and controls the horizontal deflection angle of a rotation face of the propeller, and vertical climbing and forward flight of the aircraft are achieved. The stepping motor is arranged on the base and connected with the steering engine operating arm. The supporting base is a four-leg supporting base and can be dismounted and replaced with a pulley base or a ship-shaped base. The aircraft is stable and reliable in structure, an aerial navigation mode, a land navigation mode and a water navigation mode are switched conveniently, and the aircraft can be much developed on manned aircrafts for civil use, investigation aircrafts for military use, water search-and-rescue aircrafts and other.

Description

technical field [0001] The invention belongs to the field of aircraft manufacturing, and in particular relates to a novel aircraft structure, which can simultaneously satisfy various navigation modes such as air flight, land navigation and water surface navigation under the condition of using a single power system. Background technique [0002] Compared with fixed-wing aircraft, vertical take-off and landing aircraft are favored by many people because of their smaller take-off site restrictions and stronger air retention capabilities in small areas. However, whether it is a helicopter in the traditional sense or a multi-rotor that is popular now, without adding additional power devices, they all lack the ability to move on land and water. In special areas where flight is restricted or the space is low, the aircraft can only be transported manually, and there is a danger of falling into the water when an emergency landing is required when flying above the water. Above all, h...

Problems solved by technology

However, whether it is a helicopter in the traditional sense or a multi-rotor that is popular now, without adding additional power devices, they all lack the ability to move on land and water.

In special areas where flying is restricted or the space is low, the aircraft can only be carried manually, and there is a danger of falling into the water when flying above the water in case of an emergency and an emergency landing

All of the above seriously limit the function of vertical take-off and landing aircraft

If an additional power unit is added to achieve land and water navigation capabilities, it will not only make the aircraft structure more complex and cost higher, but also increase the weight of the aircraft itself
