Abstract
The invention discloses a vertical take-off and landing plane, and particularly relates to a novel tiltable rotor wing vertical take-off and landing plane which comprises a front pulling rotor wing, a rear pushing rotor wing, a fixed wing and a plane body. The novel tiltable rotor wing vertical take-off and landing plane is characterized in that the total quantity of rotor wing shafts is more than or equal to 4. The common quantity of the shafts can be 4, 5, 6, 8, 10, 12, 16, 18 and 20. Such arrangement ensures that the plane still possibly safely lands when a certain rotor wing system in a take-off and landing process fails, and thus the integral safety performance is improved. The front pulling rotor wing can be vertical to a ground plane and is tilted to be parallel with the ground plane from the direction, a rear pushing propeller can be vertical to the ground plane and is tilted to be parallel with the ground plane from the direction, and axial directions of a front pulling propeller and the rear pushing propeller are the same as acting directions of the front pulling propeller and the rear pushing propeller after the propellers are parallel with the ground plane. Compared with the prior art, the novel tiltable rotor wing vertical take-off and landing plane has the beneficial effects that multiple tiltable shafts provide a proper redundancy for the take-off and landing safety, and the difficulty of flight control is reduced. The fixed wing provides a lift force required by counteracting the weight in a flat-flight process. The flight energy consumption is less.
Description
[technical field]
The present invention relates to a kind of vertical take-off and landing aircraft (VTOL aircraft), particularly a kind of vertical take-off and landing aircraft (VTOL aircraft) that can tilting rotor.
[technical background]
The vertical take-off and landing aircraft (VTOL aircraft) existing at present mainly can be divided into following several types:
1 autogyro;
2 Multi-axis aircrafts;
3 tilt rotor aircrafts
The vertical take-off and landing aircraft (VTOL aircraft) landing of this three types is very convenient.But the problem of first kind autogyro is, quite complicated on physical construction.Once going wrong, power system is difficult to ensure the safety of persons on board and aircraft.
Equations of The Second Kind Multi-axis aircraft, owing to adopting many rotor structures, safe falling likely still in the situation that of part rotor system fault.
The aerocraft of above two kinds of vertical takeoff and landing is because its lift and the power advancing produce by the screw propeller rotation of driving engine or motor completely, and its thrust-weight ratio often requires to be greater than 1.In flight course, energy consumption is larger.
The 3rd class aircraft as: combine the shortcoming of fixed-wing and vertical takeoff and landing, flight efficiency is greatly improved, voyage is farther, has also had the advantage of vertically taking off and landing flyer maneuverability concurrently; What this class aircraft was especially representative is U.S. army " osprey " tiltrotor, the vertical takeoff and landing tilting rotor wing unmanned aerial vehicle " black panther " that the YY-1 of group company of Qingan County of Air China short distance/VUAV and space flight industrial of Israel produce." osprey " is the aircraft based on diaxon, and the requirement that flight is controlled is very high, frequently the meeting accident of " osprey " make everybody seek to be easier to handle and safe design.Tilting rotor wing unmanned aerial vehicle " black panther " is the aircraft based on three axles, is easy to handle, and safety is good, but in flat flight course, tail undercarriage can not provide power forward;
[summary of the invention]
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of electric airplane of vertical takeoff and landing.There is the peaceful low energy consumption characteristic in journey and safer than traditional tilt rotor aircraft of flying over of the vertical takeoff and landing performance identical with tiltrotor, more easily control.
The technical solution adopted in the present invention is: a kind of aircraft of vertical takeoff and landing, it draws screw propeller, pusher screw propeller and fixed-wing before including.Wherein, frontly draw axially can verting back and forth in horizontal and vertical direction of screw propeller and pusher screw propeller.In landing process, the front axis direction of screw propeller and pusher screw propeller that draws is perpendicular to ground level.Turn to flat flying in journey, front drawing with the axis direction of pusher screw propeller gradually from forwarding to perpendicular to ground level and the direction of ground level level.Before draw screw propeller to provide pulling force in aircraft front side to aircraft.Pusher screw propeller provides thrust at aircraft rear side.Before draw with the number of axle of pusher screw propeller and be more than or equal to 4.The common number of axle can be: 4,5,6,8,10,12,16,18,20; Like this be arranged so that in landing process minority rotor system fault in the situation that, aircraft still may safe falling, has improved overall safety performance.
Fixed-wing wing produces and determines lift in horizontal flight process, reduces energy consumption.
Compared with prior art, the invention has the beneficial effects as follows: the safety that the multiaxis that can vert is landing provides suitable redundancy have higher safety and reduced the difficulty that flight is controlled.The flat fixed-wing that flies in journey provides and offsets the needed lift of weight.The energy consumption that makes to fly is less.
From above-described content, following development of such vertical lift aircraft holds out broad prospects.
[brief description of the drawings]
As shown in drawings:
The aircraft schematic diagram of Fig. 1 vertical takeoff and landing state;
Fig. 2 can screw rudder propulsive mechanism schematic diagram;
The flat aircraft schematic diagram that flies state of Fig. 3;
A kind of 4 axle aircraft schematic diagrams of Fig. 4;
Before drawing screw propeller vertical operation state, 1b before 1a, draw screw propeller horizontal operation state, 2a pusher screw propeller vertical operation state, 2b pusher screw propeller horizontal operation state, 3 to there are fixed-wing, 4 fuselages, 5 heads, 6 empennages of lift aerofoil profile;
[specific embodiments]
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated, but protection scope of the present invention is not subject to the restriction of this embodiment.As shown in Figure 1, in one embodiment, vertical take-off and landing aircraft (VTOL aircraft) of the present invention has 8 screw propellers.Wherein 4 are drawn screw propeller before front side is, 4 is pusher screw propeller at rear side.In the state shown in Fig. 1,8 screw propeller rotor shaft direction are all in vertical direction.
As shown in Figure 2, front S. A. direction of drawing screw propeller and pusher screw propeller can 90-degree rotation, and 1a draws screw propeller vertical operation state before being, 1b draws screw propeller horizontal operation state before being.2a is pusher screw propeller vertical operation state, and 2b is pusher screw propeller horizontal operation state.
As shown in Figure 3, this 8 axle vertical take-off and landing aircraft (VTOL aircraft) before draw, pusher screw propeller is all in horizontality.
In the process of vertical takeoff and landing, the rotating shaft of screw propeller is all in plumbness.Be equal to traditional Multi-axis aircraft.After taking off, the rotor shaft direction of screw propeller progressively rotates to horizontal direction from vertical direction.Screw propeller does work and flies forward in promoting aircraft.The lift that the fixed-wing of aircraft produces and the gravity of aircraft offset.
As shown in Figure 4, be the 4 a kind of possible axle forms of this type of aircraft.The fixed-wing of this aircraft connects into a box-shaped.This aircraft draws screw propeller and 2 pusher screw propellers before having 2.
