Description
Technical field
The utility model is related to air vehicle technique field more particularly to a kind of vector for vertical take-off and landing drone are pneumatic
Rudder ducted fan.
Background technology
Fixed-wing unmanned plane has big height, big flying speed range, long endurance, big voyage, and larger load etc. is permitted
Various advantages.But fixed-wing unmanned plane needs the takeoff ground of certain length, width and surface quality to be used as
Fly landing place.With the increase of unmanned plane weight, the requirement of site requirements and spatial domain for take-off and landing increased.
This requirement to place and spatial domain is a significant obstacle in the application of fixed-wing unmanned plane.
In order to overcome and reduce this pressure to landing site, catapult-assisted take-off, parachuting landing have become solution or more
A difficult important breakthrough.This landing mode or similar landing mode should say it is successful, and be applicable in aircraft
Property, reliability are also acceptable.But catapult-assisted take-off, parachuting recycling certain ground and spatial domain using also also suffer from compared with
Big limitation.Especially in mountain area, the water surface, sea, forest area.Due to wind direction, prominent wind, spatial domain, landforms and damage or lose winged
The possibility of machine is very big.
Therefore, the phenomenon that unmanned plane becomes a kind of current public development using VTOL mode.Since 2013 to
The present in the Chinese popular lifting force for installing " carrying pole type " lift free spiral rotation paddle on wing or on fuselage additional and providing VTOL, adopts
It is emerged one after another with the VTOL scheme of thrust free spiral rotation paddle, it is very strange, fill Chinese unmanned plane market.
This " carrying pole type " formula, based on air free spiral rotation starch（Do not justified around the paddle of air free spiral rotation slurry
The duct of tubular surrounds, and the rotative power of engine is converted to propulsive force or lift by blade directly exposed rotate in air
Device）Vertical take-off and landing drone due to disadvantage intrinsic in principle and structure design so that such unmanned plane is only capable of applying
In small-sized, low-speed unmanned aerial vehicle, practicability is poor.It was verified that no matter using which kind of air free spiral rotation paddle as vertical lifting force
With undertake thrust simultaneously, and the vertical take-off and landing drone without enough feather modes all suffers from dynamical system efficiency
Problem.
One of dynamical system efficiency is starched based on " carrying pole type " formula air free spiral rotation：The rising of VTOL low speed can not
Meet level speed requirement.By present most small and medium size unmanned aerial vehicles using piston type fuel oil, gas engine as dynamical system,
Or the total arrangement using motor as system, the rate of climb of VTOL are both less than 8 meter per seconds, or only 3-4 meter per seconds.
And such unmanned plane pushes away to maintain an equal level and flies required minimum stalling speed generally in 15-40 meter per seconds, it is clear that such unmanned plane hangs down
The straight rate of climb cannot be satisfied unmanned plane and maintain flat winged required minimum speed.In order to keep dynamical system efficiency, improve and hang down
The rate of climb of straight landing, unmanned plane propeller just necessarily varying pitch paddle, but displacement paddle brings construction weight to increase, reliably
Property decline, by the mechanism technology level of current unmanned plane for, rotating speed be up to the construction weight of thousand turns of small-sized pitch-changing mechanism with
Reliability is unsatisfactory.
The two of dynamical system efficiency are starched based on " carrying pole type " formula air free spiral rotation：Large diameter air free spiral rotation paddle
Almost without the possibility of implementation.For vertical take-off and landing drone of the minor diameter free spiral rotation paddle as the low speed rate of climb, move
Force system inefficiency.Therefore, when the take-off weight of unmanned plane increases, this minor diameter paddle can hardly be received, and be
This will replace free spiral rotation paddle using larger diameter rotor.But in this way major diameter rotor there are few may with it is thousands of, to up to ten thousand
The motor synchronous working of rev/min rotating speed, therefore necessarily with retarder, and the gearbox more than 25 horsepowers and corresponding variable-speed motor
The problem of structure design, mechanism design and dynamic Control that structure is brought is a kind of disaster for small and medium size unmanned aerial vehicles.
The three of dynamical system efficiency are starched based on " carrying pole type " formula air free spiral rotation：Lateral wind causes when wind speed is larger
Unmanned plane yaws.Due to the layout of " shoulder pole " type, when use larger diameter propeller or rotor and local wind speed is larger
When, due to the influence of lateral wind, if the automatic damping for inhibiting oscillation that the balance system of unmanned plane is not enough, causes
Unmanned plane yaws, and the flight brought therefrom is unsafe.
In addition to this, all vertical take-off and landing drone all bands are useful for VTOL device, corresponding holding equipment and control
System, these weight majorities are redundancy weight during unmanned plane job task.And thus bring many influence flights
The adverse effect of the aerodynamic configuration shape of energy.Therefore for comparing sliding race landing unmanned plane, due to the above problems, causing
All vertical take-off and landing drone all properties indexs are all low, therefore, are reduced to the greatest extent due to equipment, control, weight, pneumatic
The unfavorable factor that power loss is brought is the task most outstanding of vertical take-off and landing drone.
To sum up, vertical take-off and landing drone will solve small-sized, low speed, yaw, redundancy weight issue.

The advantages of the utility model and effect：
1, the utility model effectively increases the efficiency of ducted fan using ducted fan pipe design technology：Due to fan
The gap very little of blade tips and duct wall, only 0.5mm, therefore the point effect of blade have two big effects, and one is to maintain leaf
Plate plane high pressure draught below does not flow back, simultaneously because it is almost 0 that blade tip vortex drag, which is reduced, to substantially increase effect
Rate, the ducted fans of a diameter about 400-800mm diameters can generate about 30-150 public affairs in 8000-12000 revs/min of low speed
The axial force of jin realizes and generates prodigious axial force with smaller duct diameter, this be free spiral rotation paddle it is incomparable,
To solve the problems, such as free spiral rotation paddle if weight, efficiency is low if using minor diameter using loading if high-power.

1, the low reason of air free spiral rotation slurry pneumatic power system efficiency is that air free spiral rotation is starched in design principle and set
Have the shortcomings that in meter structure natural：Free spiral rotation paddle directly rotates in air, and cylindric duct does not surround surrounding,
Ducted fan compared to same diameter cannot be included in duct due to fan, and the climbing power generated weakens, and climbing power weakens
Necessarily reduce unmanned plane total weight；Climbing power weakens the state that unmanned plane can only maintain low speed to rise that also results in；Due also to existing
It is always single direction vertically downward to have the axial force direction that technology air free spiral rotation paddle generates, cannot be with the change of wind direction
Change flexibly to generate and resist the injection aerodynamic force of different wind directions, therefore bad weather caused by also cannot resisting strong wind is to unmanned plane
Harm.
2, the principle of prodigious axial force is generated using smaller duct diameter：Due to fan blade end and duct wall
Gap is sufficiently small, and the sufficiently small gap is only 0.5mm, therefore to be to maintain blade plane below for the point effect one of blade
High pressure draught does not flow back, second is that being almost 0 since blade tip vortex drag is reduced, to greatly improve the efficiency, this is freely
Propeller is incomparable, since the pneumatic rudder of the utility model vector can generate very compared to existing low speed, small drone
Big axial force, therefore, unmanned plane VTOL lift increase, and since vertical lift increases, the total landing weight of unmanned plane can be with
Increase, the rate of climb increases.
3, the double angle complex functionality design principles of the pneumatic rudder of the utility model vector：Although it is inclined that leaf coral blade makees 0-180 degree
Turn that the direction of air-flow can be changed, but if duct can not be allowed to rotate, leaf coral blade can only change the gas of the current direction of leaf grating
Direction is flowed, and the airflow direction of all directions cannot be changed, this is because leaf coral is to immobilize relative to the position of duct wall
Cause.Since the wind direction in air is not fixed, wind direction can come from any one angle in 360 degree of planes, to
The influence of any wind direction is resisted, must just duct be allowed to be rotated together with wind direction so that is fixed on the direction of the leaf coral on duct
Also with changing together, the direction of only leaf grating is moved with the wind, could effectively be resisted the crosswind of different directions and be influenced.
4, the utility model reduces the principle of unmanned plane redundancy weight using the pneumatic rudder of vector：Since the pneumatic rudder of vector replaces
The VTOL device of the prior art, the function of corresponding holding equipment and control system are replaced with part so that VTOL fills
It sets, the function of corresponding holding equipment and control system " shared " as much as possible or the pneumatic rudder of " partial common " vector, to as possible
The mechanism and construction weight for VTOL are alleviated, has been reduced to the greatest extent due to vertical machine drop equipment, control, weight, pneumatic
Power loses the unfavorable factor brought.
