Description

A kind of new double ducted fan formula personal aircrafts

Technical field

Culvert type aircraft and vertically taking off and landing flyer field are the utility model is related to, more particularly to a kind of new double culverts Road fan-type personal aircraft.

Background technology

Existing domestic low latitude gradually opens, and General Aviation is fast-developing, and all kinds of aircraft arise at the historic moment.Common fixed-wing flies Row device is ripe and extensive, but the plane track that the aircraft designed using fixed-wing needs to grow can just take off very much, it is impossible to realizes and hangs down Straight landing and hovering.Rotor craft has unique advantage, it is possible to achieve VTOL, but rotor craft itself In place of Shortcomings：Payload is small, cruising time is short, easily disturbed.Therefore develop one kind can VTOL, and can be Flexible aircraft turns into the study hotspot in aircraft field in complicated air situation, the utility model proposes it is a kind of new pair Ducted fan formula personal aircraft is expected to preferably resolve these problems, can realize VTOL, the overhead suspension of aircraft Stop and multi-faceted flight.

The content of the invention

The utility model is mainly solving the technical problems that provide a kind of new double ducted fan formula personal aircrafts so that Aircraft can be controlled when carrying out flight by adjusting ducted fan rotating speed come the flying height of change of flight device by both hands The rotating speed of the lever regulated two duct thrust fans of duct and direction is promoted to come the flying speed and heading of change of flight device, And then realize the VTOL, hovering and multi-faceted flight of aircraft.

In order to solve the above technical problems, a kind of technical scheme that the utility model uses is：A kind of new double ducted fans Formula personal aircraft, including the first lift ducted fan part, the second propulsion ducted fan part, fuselage cab portion and rise and fall Frame part；It is characterized in that：The middle lower section in the first duct main body frame edge and fuselage seat in first lift ducted fan part Welded above fuselage cradle in the part of cabin；Second promotes in support bar lower end and fuselage cab portion in ducted fan part Middle part cross bar welding；Undercarriage part is the lower end by the cambered rod member of two both ends bands and fuselage cab portion middle fuselage frame Welding, the right and left respectively weld one；First lift ducted fan part, second promote ducted fan part, fuselage cockpit portion Divide and undercarriage part is integrated a kind of new double ducted fan formula personal aircrafts of composition altogether.

Further, the first lift ducted fan part is by the first motor, the first motor base, the first fan oar Leaf, the first duct wallboard, duct annulus, duct floor, cross carrier bar and the first duct main body frame composition；Its feature exists In：First fan blade is docked and fixed with the upper surface of the rotating shaft of the first motor by bolt, and the first motor is consolidated by bolt It is scheduled on above the first motor base, the first motor base is fixed on the center of cross carrier bar and is welded as a whole, and cross is held The part that bar is the first duct main body frame is carried, the first duct main body frame is welded by tubing, the first duct The outer surface of wallboard is docked with the inner face of duct annulus and in the upper end of duct wallboard, at top edge 20-30mm, passes through small spiral shell Bolt is fixed, and bolt sequentially passes through the first duct wallboard, duct annulus, duct floor from inside to outside, while in the first duct wallboard Lower end, at lower edge 20-30mm, fixed also by stove bolt and duct floor, bolt sequentially passes through first from inside to outside Duct wallboard, duct floor, beam of the duct floor along the first duct main body frame are distributed in four diagonal positions and fixed with bolt A rock-steady structure is connected and composed, as shown in Figure 4.

Further, the second propulsion ducted fan part is by the second motor, the second motor base, the second fan oar Leaf, the second duct wallboard, swivel bearing, duct connecting rod and support bar group into；It is characterized in that：Second fan blade passes through bolt Docking and fix with the upper surface of the rotating shaft of the second motor, the second motor is bolted on above the second motor base, Second motor base is fixed on the inner surface of the second duct wallboard, and two ducts of the second propulsion duct are connected to duct connecting rod Both ends, both ends and the motor base and the second duct wallboard of duct connecting rod are connected as a single entity, general to use welding or bolt connection, The middle part of duct connecting rod and the upper weld of swivel bearing, swivel bearing bottom are fixedly welded on the upper end of support bar again, Form whole second and promote ducted fan part.

Further, the fuselage cab portion is seat, fuselage cradle and battery composition；It is characterized in that：Fuselage cradle is It is welded by tubing, as shown in fig. 6, seat is fixed on two cross bars of fuselage cradle, battery is placed below seat simultaneously Fixed and be installed in cockpit with bolt.

A kind of flight theory of new double ducted fan formula personal aircrafts of the utility model is：When aircraft prepares vertically When taking off, two motors in the first lift ducted fan part rotate backward（Balance its reaction torque to fuselage）, reach flat Surely take off, when increasing by two output power of motor simultaneously, rotation speed of the fan, which increases, causes total life increase, when it overcomes main screw lift When, aircraft, which is realized, to take off vertically；After aircraft vertical takes off, flat winged pattern is initially entered, now second promotes ducted fan Part is vertical with aircraft direction of advance, and two propulsion electric machines start power output, produces thrust, carries out aircraft and puts down forward Fly；During hovering, only by a pair ducted fan need to be promoted to close, by a pair of lift ducted fan output lift；When winged When the flight of row device is turned, duct connecting rod accordingly changes angle, controls its radius of turn by the difference of rotational angle, is realized with this The multi-faceted flight of aircraft；When aircraft lands, a pair of propulsion ducted fan motors are stopped, a pair of lift duct wind Fan motor and reduce power output, rotation speed of the fan, which reduces, causes total life to be gradually less than complete machine gravity, and fuselage slowly lands, and realizes and flies The grease it in of row device；During aircraft flight, aircraft water stationarity can be influenceed by some uncertain factors, on the other hand, By controlling the output of a pair of lift ducted fan output power of motor, to realize the stability of aircraft horizontal direction.Pitching The stability in direction is mainly influenceed by air-flow, due to significantly reducing the center of gravity of fuselage during design, works as airflow influence To aircraft pitching stability when, body nodal point is enhanced, and under gravity, aircraft can recover to normal position automatically Put, to realize the center of gravity of aircraft from steady.

The beneficial effects of the utility model are：The utility model enables to can be according to need when carrying out Flight Vehicle Design The duct of different capacity is selected to combine, two duct lift fan main functions are to provide lift for personal aircraft, and are protected The stabilization of personal aircraft is held, fuselage both sides are respectively designed with a propulsion ducted fan, are controlled by both hands and promote duct connecting rod The flying speed and heading of change of flight device are come in the rotating speed of two duct thrust fans of regulation and direction, and then realize flight VTOL, hovering and the multi-faceted flight of device.
