Abstract

The present invention relates to a high control airscrew used for improving flying vehicle speed and its running state. It is characterized by that the production of control is used for regulating push-pull force and the flexible variable pitch from bearing to blade so as to obtain ideal running state. Its structure is simple and reliable, and its cost is low.

Description

Shape changeable propeller constitutes and operating method

The present invention relates to the height control of aircraft spiral in blower fan, the water turbine in a kind of mechanical field, big displacement constitutes and unique operating method.

At present, the spiral aircraft constitutes in the forward position, the rotary wing changing distance, and the operation scheme under its formation and the formation thereof is limited to its essence inherence, i.e. the breakthrough of running state.Other, the formation of electromagnetism (as the adjustable spiral of Germany), this goes on a journey in control, from consideration such as price, reliability, alerting ability itself and show that the most close control is essential.Concrete manifestation: rotary wing changing is apart from being better than adjustable spiral, but more complicated, constitutes unidirectionally, is exactly that it has only considered to allow rotor how produce the power of drawing high, and rule is first displacement, rotates again; Only rest in 90 degree on elongation changes, like this, rotation adds elongation takes off, and adds the power rotation again and adds elongation and soar.On the contrary, landed by gravitating, flight course was a continuous working process originally, in order to land, must subtract apart from subtracting power, attracted to fall with being subjected to.Flight efficiency reduces, rises, descends therebetween, and criteria factor such as flying speed are slow, and is just big inharmonious as air objective is quick.The track state of other contact, the resistance state, price can be operated, and vibrations etc. can not be broken through under old formation and operation scheme.

The operating method that the objective of the invention is to a kind of simple formation and the most approaching motion essence.This formation is to remedy the defective that rotor constitutes, by displacement and its scope thereof, add the distortion operating method, obtain states such as the positive antagonistic force of the moment generation of spiral, zero resistance, continuous Gao Xuan, coordinate quick, and comprising the state of helicopter characteristics, other also can be used to separate helicopter spiral status drawback by no means, even certain breakthrough of jet airplane.

The objective of the invention is to realize by following novel formation, this formation comprises: Dui Cheng blade highly, but blade rotation 180 degree are got in touch with dynamical axis, contact place has anti-blade exocentric structure, this structure be used in addition with dynamical axis on the dynamical axis sleeve pipe Adjustable length rod that can slide up and down link together, the dynamical axis sleeve pipe is with bearing or hollow rotating shaft.The line reference that is as the criterion of above-mentioned dynamical axis center ordinate, above-mentioned all parts are all by this line rotation symmetry.Above-mentioned dynamical axis sleeve pipe and dynamical axis are had to slide up and down; Must not relatively rotate and swing.Outer race or hollow rotating shaft and sleeve pipe are had to relatively rotate, and must not slide up and down and swing.Secondly, blade turning handle place has to rotate swing, and must not slide, must not be centrifugal.The rotation symmetry number that blade is relevant distributes with 2 or 3 multiple circumference in equal parts.

Another object of the present invention is to provide a kind of operating method, this method is the shape changeable propeller operating method:

This method is achieved in that at first shape changeable propeller and actuator, control system is connected that connection has two kinds, and a kind of is fixed type bearing, (promptly fixing) with airframe, when being used as power an imput power, dynamical axis connects down the controlling point of push-and-pull the dynamical axis sleeve pipe, and second kind is the stationary power axle, promptly it is connected with actuator, bearing connects the controlling point, and first kind, the controlling point preferably possesses the signaling transfer point of bearing, second kind, the most handy bilayer sleeve upper and lower translation in controlling point.In addition, the application of internal control formula shape changeable propeller can be with reference to this method.

After connecting, spiral is transferred to zero resistance angle, promptly elongation is zero, is threaded to the most at a high speed; Under power unmodified situation, drop-down displacement produces pulling force, on push away displacement and produce thrust.Going up drop-down terminal point, is respectively positive and negative 90 degree elongation, at this moment positive negative sense zero resistance, and tangent line is to the resistance maximum point, and this is suitable for helicopter class tangent line to the connection of using.Outside inferior, blade elongation reach or after move 90 degree elongation and connect, be suitable for non-helicopter class aircraft and connect; Here should clear and definite elongation here need and become with reference to velocity variations fully.It is zero degree, 90 when spending that the positive negative sense of spiral is used elongation, and thrust is zero, and zero degree is to the interval application forces that produce of positive and negative 90 degree.

Advantage of the present invention is only to control 180 degree elongation, and power is constant, thus state handle with consciousness fully, moment is obtained positive and negative to thrust or zero thrust, and runs without interruption, and is quick.Also comprise simultaneously original flight operation characteristic, fundamentally solve motion and the coordination of flying, thus easier control.Constitute simple and reliablely, cost is low,

Constituting legend explains:

Shown in the legend, shape changeable propeller 1 of the present invention, comprise blade 2, anti-centrifugally regulated point 3, ratch 4, sleeve pipe 5, bearing 6, dynamical axis 7 more than constitutes with

blade

2, and 3,7 and 4,5,6 relevant slide relative, wherein 2 can change 180 degree elongation under 3 keeping, and 4 can be Adjustable length rod, and 5 and 4 can be one whole, 5 and 6 sockets, 6 can be hollow rotating shaft or the bearing combination that can finish the bearing function.But 6 and 7 slide relative; Must not swing.Above-mentioned formation is 2,3,7 being an integral body, and 4,5,6 is one wholely to constitute; (do an integral body to 2,3,5 in addition, do an integral body to 4,6,7 and constitute, then 6 should be enclosed within on 7,7 is adjust bar, and 5 is dynamical axis, then forms and Fig. 1 internal control formula shape changeable propeller arranged side by side).

More than combination is preferably under the situation that does not hinder operation, and the shell of establishing a similar streamlined reefer housing is with suitable extraneous operation.For example, prevent that the gear ratch from blocking.If ratch 4 replaces with displacement connecting rod, pitch hinge, blade moves down slightly shown in Figure 1, and other is motionless.

Externally controlled type shape changeable propeller Fig. 1; And internal control formula shape changeable propeller constitutes and only to have done the open type example and separate, and its ring enclosed auger can be corresponding with the ring enclosed of present use.
