Description

Hybrid power four dual rotation propeller tiltrotor

Technical field

The tiltrotor of a kind of hybrid power, energy VTOL and fixed-wing flight, possess higher safety, belong to Technical field of aerospace.

Background technology

Presently, there are a large amount of four-axle aircraft, although have preferable stability and operability, but be because Flight Vehicle Structure Limitation, it is impossible to realize high speed cruise flight；If its four set propeller and motor any one break down, four-axle aircraft Aircraft will be caused out of control because propeller rotation counteracting force can not balance；And its battery energy storage is limited, it is impossible to long distance From flight.

The tiltrotor the most uniquely produced at present and come into operation is V-22 " osprey " tiltrotor of the U.S.. Although it achieving VTOL and remote high-performance cruise, but the analysis run for many years according to it: this tilting rotor Machine is because DCB Specimen structure, and rotor load is too high, easily produces ring of eddy；The rotating speed of fuel engines and power control response speed Degree is relatively slow, poor in the emergency capability of emergency；In order to balance the rotation counteracting force of rotor, DCB Specimen must with reversely and Identical rotating speed rotates, if the lift having occurs abnormal, aircraft then can disequilibrium；Fuel engines is positioned at propeller Rear, high velocity air causes electromotor easily to inhale sand；Ground and ground staff are had by the high-temperature gas that electromotor sprays downwards The biggest impact；These cause this type aircraft vertical landing and the stability of hovering, reliability and safety the most undesirable.

Summary of the invention

This utility model design one can be carried out remote high speed with fixed-wing flying method again patrol with VTOL Boat, and possess higher-security and handling novel tiltrotor.

This utility model be the technical scheme is that employing four set can independently be adjusted the same of rotating speed by motor-driven Axle contrary turning propeller, rectangular location arrangements two ends of fixed-wing before and after tandem rotor aircraft together with motor, and four The direction of principal axis of set propeller can deflect.Afterbody is provided with empennage.Four set motors be equipped with special motor driver for Control and adjust rotating speed and the power of motor.When four set rotors direction of principal axis vertically time, it is possible to achieve VTOL And hovering, by adjusting direction of principal axis and the lift of four groups of propellers, it is achieved various flight attitudes control；By changing four set spirals The direction of principal axis of oar, to forward horizontal direction, is converted to fixed-wing offline mode, it is achieved remote high-performance cruise is it can also be used to short distance From sliding takeoff and landing or providing bigger physical burden.Under fixed-wing offline mode, adjust fixed-wing and empennage Movable aerofoil and four groups of propeller shaft directions of deflection all can realize the control to flight attitude.Aircraft uses oil electricity mixing dynamic Power, is driven electrical power generators and power battery pack can be all that aircraft provides electricity by turboaxle motor or piston engine Power, electromotor can be power battery pack charging simultaneously.

The beneficial effects of the utility model are: use the dual rotation propeller of four groups of rectangle location arrangements, not only reduce Rotor load under VTOL pattern, and reduce the front face area of rotor under fixed-wing offline mode, reduce flight resistance； Its four sets dual rotation propeller, can not for the symmetric screw propeller rotating speed control constraints to the rotation counteracting force of aircraft Freely to adjust rotating speed change lift and direction of principal axis, it is possible to achieve various flight attitudes control and emergency trouble shooting measures；Can be real Now turn the most mutually between fixed-wing offline mode and VTOL pattern and transition process is more stablized controlled；Can use solid Determine wing offline mode, it is achieved the cruising range farther relative to pure helicopter, lower flight energy consumption and higher cruise speed Degree.This tiltrotor possesses preferable safety: by peak power in short-term and quickly response and the electrokinetic cell of motor The repid discharge of group, it is provided that Ability of emergency management the most in emergency circumstances；When a set of propeller electric machine assembly or motor During driver malfunction, the other set propeller on the diagonal of rectangle position can be allowed to be served only for aircraft balance and stability and to control, And a pair propeller on an other diagonal operates with double power, it is provided that enough lift, real before motor overtemperature Execute emergency landing.Four set propellers, have many power redundant safety mechanism under Fixed Wing AirVehicle pattern.Use oil electricity mixing Power, it is possible to use electrical power generators and power battery pack are discharged simultaneously provides the emergent high-power electric of short time for aircraft Or raising maximum take-off weight；When fuel power or power battery pack break down, fuel power provides with electromotor Electric power or the high power discharge of power battery pack, it is possible to the time of troubleshooting is provided for aircraft, or be urgent the most urgent Fall provides short time electric power.

Detailed description of the invention

In embodiment illustrated in fig. 1, four set dual rotation propellers and the rectangular position of rotor assemblies 5,6,7,8 of motor composition Put the two ends being arranged in before and after's fixed-wing 2,3；Often group dual rotation propeller direction of principal axis can deflect.In fuselage 1 permissible Arrange oil-fired power generating dynamical system and power battery pack and flight controller etc., also can arrange manned driving cabin.Shown in figure For VTOL pattern, by changing the lift of propeller, it is possible to achieve the various gesture stability in addition to rotation, as flat Move, pitching etc.；By the dual rotation propeller 5,8 on the left of the differential deflection of low-angle and the dual rotation propeller 6,7 on right side, Rotation gesture stability can be realized.Safety operation mode is to assume dual rotation propeller 5 because various possible reasons lose Lift, at this moment the two groups of dual rotation propellers 6 and 8 in clinodiagonal improve rapidly lift, for aircraft in peak power Thering is provided enough lift, and the posture balancing that dual rotation propeller 7 changes into for aircraft is stable, then aircraft is carried out tightly Urgent fall.

Fig. 2 is the fixed-wing offline mode schematic diagram of same embodiment.Four groups of dual rotation propeller 5,6,7,8 direction of principal axis Deflecting forward, aircraft promotes along with flight speed, and when fixed-wing 2,3 can provide enough lift, four groups the most anti-simultaneously Rotating propeller 5,6,7,8 direction of principal axis deflects to level angle completely, provides only forward pulling force, does not reoffer lift, hence into Low energy consumption and fixed-wing offline mode at a high speed.Can be with change of flight direction by handling empennage 4；Its gesture stability is referred to The control mode of tradition fixed wing airplane, it would however also be possible to employ the dual rotation propeller direction of principal axis of small angle deflection both sides comes real Existing: when the dual rotation propeller direction of principal axis at fixed-wing 2 or rear fixed-wing 3 two ends before small angle deflection in the same direction, Ke Yishi Existing body pitching operates, climbs or reduce flying height；When before differential small angle deflection fixed-wing 2 or after fixed-wing 3 liang During the dual rotation propeller direction of principal axis held, it is provided that rolling moment.Owing to there being 4 groups of propellers to provide advance pulling force, itself There is redundancy scheme, if it occur that propeller fault, still can implement slide forced landing and take off.

The power safety mechanism of aircraft is that fuel engines drives electromotor and power battery pack to backup each other, and can be all Aircraft provides short time emergency electric power, allows aircraft have certain time to fix a breakdown or implements forced landing.
