Abstract

The utility model relates to a four-propeller aircraft taking off and landing vertically, which is provided with small-diameter propellers, and can realize vertical taking off and landing and fast flying without special requirements on the strength of wings. Two propellers capable of upward and forward rotating are arranged in front of and at the back of the wings, the four propellers are respectively arranged at two ends of a front cross shaft and a rear cross shaft which can rotate, and the front cross shaft and the rear cross shaft are connected with a control handle together by a connecting shaft. A horizontal rudder is arranged at the rear part of the wings, and a vertical rudder is arranged at the rear part of the aircraft. The propeller faces upward when the aircraft takes off and lands, and faces forward when the aircraft flies horizontally. The horizontal rudder controls the ascending and descending of the aircraft, and the vertical rudder controls the left and right steering of the aircraft.

Description

The quadruple screw propeller VTOL aircraft
Affiliated technical field
The utility model belongs to the aeronautical vehicle field, respectively is equipped with two in the front and back of aircraft and can makes progress and the screw propeller that rotates forward, and the top of aircraft is equipped with a fixed wing, and there is diving rudder at the rear portion of wing, and there is steering rudder at the aircraft rear portion.Make progress or rotate screw propeller forward and can make aircraft VTOL or horizontal flight.
Background technology
At present, known VTOL aircraft has two screw propellers that can rotation direction be installed in the wing two ends, enough lift when the aircraft VTOL is provided, and screw propeller must be very big, and is very high to the requirement of strength of wing.
Summary of the invention
In order to overcome the too big and deficiency high of existing VTOL aircraft screw propeller to the wing requirement of strength; The utility model provides a kind of quadruple screw propeller VTOL aircraft; Four screw propellers of this quadruple screw propeller VTOL aircraft are installed in four jiaos of wing below; Four diameter of propeller are less, and wing intensity is not had specific (special) requirements.
The utility model solves the technical scheme that its technical matters adopted: respectively be equipped with two before and after below wing and can make progress and the screw propeller that rotates forward; Four screw propellers are installed in former and later two rotary transverse axis two ends respectively, and connecting rod links together former and later two transverse axis and control handle.The rear portion of wing is equipped with diving rudder, and the rear portion of aircraft is equipped with steering rudder.When taking off, let screw propeller up, engine drives screw propeller rotation, the pulling force that makes progress that produces when four screw propellers is taken off during greater than aircraft weight; Aircraft slowly promotes control handle forward after arriving certain altitude, and four screw propellers that connecting rod drives two transverse axis two ends rotate forward; When aircraft reaches certain speed; When the lift that wing produces and the weight of aircraft reach balance, forward screw propeller to fully forward position, aircraft promptly changes horizontal flight into.The rising or the decline of the diving rudder control aircraft of aircraft turn to about the steering rudder control aircraft of aircraft.When aircraft landing, the pulled backwards control handle lets four screw propellers up, reduces the rotating speed of screw propeller, can realize the vertical landing of aircraft.
The beneficial effect of the utility model is, do not needing very big screw propeller, wing intensity do not had under the situation of specific (special) requirements, can realize the VTOL of aircraft and flight fast.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the birds-eye view of quadruple screw propeller VTOL aircraft.
Fig. 2 is the lateral plan of quadruple screw propeller VTOL aircraft.
1. driving engines among the figure, 2. screw propeller, 3. wing, 4. transverse axis, 5. connecting rod, 6. diving rudder, 7. steering rudder, 8. control handle.
The specific embodiment
Before and after the below of wing (3), respectively being equipped with two can make progress and the screw propeller (2) that rotates forward; Four screw propellers (2) are installed in former and later two rotary transverse axis (4) two ends respectively, and connecting rod (5) links together former and later two transverse axis (4) and control handle (8).The rear portion of wing (3) is equipped with diving rudder (6), and the rear portion of aircraft is equipped with steering rudder (7).When taking off, let screw propeller (2) up; Driving engine (1) drives screw propeller (2) rotation, and the pulling force that makes progress that produces when four screw propellers (2) is taken off during greater than aircraft weight, after aircraft arrives certain altitude; Slowly promote control handle (8) forward; Four screw propellers (2) that connecting rod (5) drives two transverse axis (4) two ends rotate forward, when aircraft reaches certain speed, when the lift of wing (3) generation and the weight of aircraft reach balance; Forward screw propeller (2) to fully forward position, aircraft promptly changes horizontal flight into.The rising or the decline of the diving rudder of aircraft (6) control aircraft turn to about the steering rudder of aircraft (7) control aircraft.When aircraft landing, pulled backwards control handle (8) lets four screw propellers (2) up, reduces the rotating speed of screw propeller (2), can realize the vertical landing of aircraft.

Claims (2)

1. quadruple screw propeller VTOL aircraft; Respectively being equipped with two before and after below wing can make progress and the screw propeller that rotates forward; It is characterized in that: four screw propellers are installed in former and later two rotary transverse axis two ends respectively, and connecting rod links together former and later two transverse axis and control handle.
2. quadruple screw propeller VTOL aircraft according to claim 1 is characterized in that: the wing rear portion is equipped with diving rudder, and the rear portion of aircraft is equipped with steering rudder.
