Abstract

The invention relates to an airplane which comprises an engine, a fuselage, a front wing, a horizontal tail wing, a vertical wing, two non-coaxial propellers, supports of the propellers, a transmission inclinable mechanism, and the like. Because propeller main shafts arranged on the front part and the rear part of the fuselage can incline and rotate to horizontal positions from vertical positions in a horizontal plane along the fuselage, the airplane can vertically lift and horizontally fly, and the propellers having larger blade areas are like two huge parachutes in the process of landing, thus the double-propeller inclinable vertical lifting wing spread airplane has the special advantages of load capacity and good safety.

Description

Double-propeller inclinable vertical lifting wing spread airplane

The present invention relates to a kind of aircraft.

The purpose of this invention is to provide a kind of can vertical lift, the spademan aircraft that load carrying ability is big.

The object of the present invention is achieved like this: the present invention's the twin screw spademan aircraft that can incline is made up of the supporting of driving engine, fuselage, preceding wing, tailplane, vertical tail, two out-of-alignment screw propellers, screw propeller and the transmission mechanism etc. that can incline.The supporting of screw propeller and the transmission mechanism that can incline is installed in respectively on two positions of vertical tail behind forebody position and the fuselage with bearing.As Fig. 6, shown in Figure 7.Two rotor shaft can surpass 90 ° verting along work in vertical vertical plane surface of fuselage.

For realizing planting weight this purpose greatly, screw propeller adopts the screw propeller of multi-group blade propeller or many aircrafts of ring width of cloth wing formula.

The invention will be further described in conjunction with the accompanying drawings and embodiments in bottom:

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are multi-group blade propeller figure.(wherein Fig. 1 is the screw propeller front view, and Fig. 2 is the screw propeller birds-eye view, and Fig. 3, Fig. 4 are the propeller section expansion drawing) Fig. 5 is the screw propeller transmission mechanism that can incline, and Fig. 6 is the constitution diagram of aircraft lifting and landing, and Fig. 7 is aircraft level flight condition figure.2-1 screw propeller coupling link among Fig. 2,2-2,2-6 blade, the 2-3 radial spoke, the non-radial spoke of 2-4, the 2-5 propeller hub, blade and spoke quantity have only been drawn minority (purpose be for figure clear) as an illustration, actual quantity are a lot of among Fig. 2, we divide the blade with identical radius of rotation scope into one group, and it is that many groups constitute.Among Fig. 5,1, rotor shaft, 2, screw propeller, 3, rotor shaft transmission gearbox, 4,10 bearings, 5,7 conical gears, 6, worm gear, 8, power wheel (gear or sprocket wheel), 9, transmission shaft, 11, removable metal, 12 worm screws, 13, plain bearing housing, 14, the bolt group, 15, can incline mechanism and fuselage, aircraft tail shelf of plain bearing flap, screw propeller transmission forms by 11,13,15 plain bearing groups and is rotatably connected.

Embodiment:

1, takes off vertically: rotate can the incline worm screw 12 of mechanism of screw propeller, worm gear 6 rotates and drives screw propeller case 3 and rotates, make rotor shaft go to the upright position, the power wheel 8 of (back) drove part successively 9,7,5,1, No. 2 before start the engine (two) drove respectively.Screw propeller rotates, and makes the aircraft vertical uplift, by the size of the forward and backward driving engine horsepower input of control, makes fuselage keep horizontality in the uphill process.

2, horizontal flight: after rising to certain altitude, engine retard, rotation can incline worm screw, worm gear pairs in the mechanism are horizontal rotor shaft, and aircraft flies forward.

3, turning to of aircraft: the left and right manipulation that turns to is the same with the spademan aircraft.

4, climbing of aircraft: the aloft manipulation of climbing is the same with the spademan aircraft, also turns worm screw this moment, worm gear pairs, and rotor shaft is in level certain angle, can strengthen climbing speed (having the altitude dash performance).

5, landing: engine retard, close, aircraft glides, and rotary worm, worm gear pairs are in vertical position rotor shaft, the aircraft landing of gliding.If make rotor shaft be in position, back partially, aircraft glide stroke will be reduced, and can become vertically slowly decline.This screw propeller will play two huge parachute effects in the decline process.

6, advantage of the present invention: the present invention's helicopter with wings, loading capacity is big, and the landing security is good. Under the tail-off state the air crash accident can not take place.

Claims

1. the present invention relates to a kind of aircraft, it is by driving engine, fuselage, wing, tailplane, vertical tail, the supporting of two screw propellers and screw propeller and the transmission compositions such as mechanism that can incline, it is characterized in that: be installed in before the fuselage and the supporting of two rotor shaft at tail position and transmission gearbox and fuselage between be to be connected by bearing, along doing in the longitudinal plane of fuselage above 90 ° vert.

2. the twin screw according to claim 1 autogyro that can incline is characterized in that its screw propeller is by many groups with different radiuses of rotation scope, and every group of number of blade is numerous, multi-group blade propeller.
