Ground-effect-type ducted fan aircraft

Abstract

A ground-effect-type ducted fan aircraft mainly comprises a ground-effect wing bottom frame, a drop-shaped cabin, four sets of self-balance ducted fan / blade devices, a safety system and an electric power automatic control system. The four sets of self-balance ducted fan / blade devices are connected with the ground-effect wing bottom frame and symmetrically arranged on the two sides of the ground-effect wing bottom frame in pairs; the drop-shaped cabin is fixed to the ground-effect wing bottom frame and constitutes a streamlined ground-effect wing profile body together with the ground-effect wing bottom frame; the streamlined ground-effect wing profile body and the outer walls of the self-balance ducted fan / blade devices are connected through smooth hook faces; the safety system is fixed onor in the drop-shaped cabin; and the safety system and the four sets of self-balance ducted fan / blade devices are electrically connected with the electric power automatic control system fixed in the drop-shaped cabin. By using the ground-effect-type ducted fan aircraft, vertical takeoff and landing can be achieved, control is easy, the control feeling is high, safety is high, during high-speed flight, lift is provided through the ground effect, and the ground-effect-type ducted fan aircraft is suitable for the flight experience and daily flight travel.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a ground-effect ducted fan aircraft. Background technique [0002] At present, the development of aircraft is changing with each passing day. Various types of aircraft are widely used in aerial photography, agriculture, plant protection, Selfie, express transportation, disaster rescue, observation of wild animals, monitoring, surveying and mapping, news reports, power inspection, disaster relief, film and television shooting, military and other fields. However, at present, aircraft in various fields mainly use large aircraft and small or micro unmanned aircraft, and there are few small manned aircraft for ordinary people to experience flying and travel in daily life. Existing aircraft can be roughly divided into fixed-wing aircraft and gliders, rotary-wing helicopters and rotorcraft, flapping-wing aircraft, and tilting-rotor aircraft.

AI Technical Summary

Problems solved by technology

Existing aircraft can be roughly divided into fixed-wing aircraft and gliders, rotary-wing helicopters and rotorcraft, flapping-wing aircraft, and tilting-rotor aircraft. Fixed-wing aircraft and gliders generally require long take-off and landing runways and are expensive, and are generally not suitable for It is the first choice for ordinary people to do flying experience and daily life travel; the flight noise and vibration of rotorcraft and rotorcraft are relatively large, and the operation of helicopters is complicated, which is not conducive to daily life travel and flying, and the flying experience is extremely poor; orthopter is a bionic aircraft. Smaller in weight, it is more suitable for use as a drone; the tiltrotor combines the characteristics of fixed wings and helicopters as a new type of aircraft. Although it has many advantages, its high cost and complicated operation are not suitable for ordinary people's daily use and flying experience

[0003] Secondly, the emerging flying cars and flying motorcycles, as a new type of flying tool, are valued by the majority of scientific and technological workers because they can greatly use the vast airspace to solve the current troubles such as numerous ground vehicles traveling, congestion, and traffic jams. However, the current flying cars or flying motorcycles Its technical application of motorcycle is still unsatisfactory. For example, Chinese patent CN201520891060 provides a flying electric vehicle, which is composed of wheels, vehicle frame, vehicle body, propeller, engine, and a wing connected to the vehicle body through a single-hole hinge. Its characteristics are: The wheels are driven by an electric power system composed of a power motor, a power battery, and a speed controller. The wheels are steered by a manual steering mechanism, and the propeller and engine are installed at the rear of the flying electric vehicle to provide the flying electric vehicle with a level of flight in the air. The power, the wing is a triangular folding wing or trapezoidal folding wing that can be automatically folded and unfolded automatically, the suspension frame of the flying electric vehicle body and the wing are connected by a hinge ring, and the triangle joystick is operated to control the front and rear of the wing around the hinge ring Up and down, left and right, up and down to control the flight state of the flying electric vehicle, this technology has the following disadvantages: first, the manual steering and wing joystick steering and adjustment are complicated to control and poor in operability; second, due to the complexity of the operation And simple shock-absorbing safety protection measures are very likely to cause safety accidents; third, its flying electric vehicle does not conform to the principle of aerodynamics, there is a lot of air resistance, and it has no comfort at all, it can only be used as a simple The method of flying is not very practical, especially for the travel and flight experience of people in the current economic situation.

Chinese patent CN201620295204.7 discloses a flying car, which includes a vehicle frame, a front duct assembly vertically assembled at the front end of the vehicle frame, and a rear duct assembly vertically assembled at the rear end of the vehicle frame. The central axes of the duct assembly and the rear duct assembly are in the same vertical plane, and the bottom of the inner cavity of the front duct assembly and / or the bottom of the inner cavity of the rear duct assembly are distributed along the horizontal direction. Four groups of deflector components that realize the flight action of the flying car; each group of deflector components is connected to a separate deflection controller, or the same deflection controller controls four groups of deflector components respectively; this technology has the following deficiencies, one is , which uses four sets of diversion components to adjust the size of the outlet of the duct component and the direction of the wind flow. Although the reaction force of the air flow is used, the air outlet is blocked, which not only increases the wind resistance but also increases the load of the power plant, which consumes a lot of energy; Second, the spin power of its duct components cannot be self-balanced by torsional force, and symmetrical settings are required to offset the torque, which has large limitations and additional energy consumption; third, its structural setting does not use aerodynamic principles, and it is only for a The flying scheme cannot achieve high-speed flight, and the flight experience is poor; fourth, it does not have relevant safety protection measures, which may easily cause irreversible damage and personal safety accidents during manned flight
