Description

Tail vane formula vector engine

Technical field

The present invention relates to a kind of tail vane formula vector engine, it is by installing tail additional at the tail end of jet engine core engine The mode of rudder, it is achieved the gesture stability to aircraft, plays the effect that can change thrust direction similar with vector engine Really, aero engine technology field is belonged to.

Background technology

The gesture stability of existing jet plane, mainly by tailplane, vertical tail, canard or is directly come by wing Complete.New vector engine can change jet direction and adjust thrust direction by the deflection of engine tail nozzle, it is achieved be right The gesture stability of aircraft, but this technology to realize difficulty bigger.The scheme of the U.S. is to use rectangular jet, and above-below direction is respectively arranged with one Deflecting plates, can carry out small angle deflection at above-below direction respectively, to change jet direction, although simple in construction, but cannot 360 Degree turns to, and belongs to binary thrust vectoring electromotor；Muscovite scheme is by nozzle and electromotor globular hinge, to realize tail 360 degree of spout turn to, although structure is complicated, but can provide omnirange thrust, belongs to polynary thrust vectoring electromotor.2016 January 14, I to China national Department of Intellectual Property have submitted " a kind of rudder formula vector engine " (application number: 201610029666.9) patent application, it is proposed that a kind of at nozzle design level rudder and vertical rudder, by adjusting rudder face angle Degree realizes the technical solution of the multivariate vector thrust of electromotor, and the present invention makees on the basis of this technical scheme further Supplement, be the continuity of " a kind of rudder formula vector engine " technical scheme.

Technical problem

Existing vector engine is the jet direction utilizing and changing engine tail nozzle, utilizes action and counteraction power former Reason changes motor power direction, and its subject matter existed is that structure design difficulty is big, service life is low.

Technical solution

The present invention has from animal tail and controls to obtain body posture and the effect that turns to inspiration, proposes at jet-propelled Motivation core engine tail end installs the tail vane of " tail " form additional, is changed the thrust direction of electromotor by " tail effect ".This Invention technical solution: at the tail end of jet engine core engine central shaft, be designed with that extend back, can carry out The tail vane of angular deflection, when the high pressure draught of jet engine flows through tail vane, produces " tail effect by the deflection of tail vane Should ", change the thrust direction of electromotor；Described tail vane is a cone；Rudder fin, rudder fin is had to be and send out on described tail vane Motivation central shaft is equidirectional, and is perpendicular to the fin of central shaft；Described rudder fin has 4 fins, and angle is uniformly divided at 90 degrees to each other It is distributed in up, down, left and right four directions；Described tail vane is made up of the interconnective two or more tail vane of head and the tail.

Beneficial effect

By can carry out the tail vane of angular deflection in the design of the tail end of jet engine core engine central shaft, at tail vane Upper design rudder fin, not only make use of active force and the counteracting force of Jet Stream, also uses fluid mechanics principle and Bai Nu Profit principle, its deflecting force obtained more greatly, more directly, quicker, structure design is simpler, and difficulty is lower.

In figure, 1 it is fan, 2 is compressor, 3 is by-pass air duct, 4 is main duct, 5 is combustor, 6 is turbine, 7 is afterburning Combustor, 8 be tail vane, 9 be rudder fin

The preferred forms of the present invention

Two of the embodiment of the present invention shown in Fig. 3, Fig. 4 are the preferred forms of the present invention.It not only devises tail vane, On tail vane, also devise rudder fin, not only make use of active force and counteracting force principle, also use fluid mechanics principle and primary Exert profit principle, provide deflecting force swifter and more violent, quick, efficient for electromotor.

Embodiments of the present invention

Comparison accompanying drawing 1,2, Fig. 1 be the structural representation of one of the embodiment of the present invention, Fig. 2 be one of embodiment of the present invention Fundamental diagram.Fig. 1, Fig. 2 are the structure charts of a fanjet.It can be seen that in fanjet core engine The tail end of central shaft, has a long cone, it is simply that the tail vane 8 of the present invention, and Fig. 1 is shown that the normal condition of tail vane 8, Fig. 2 is shown that the duty of tail vane.Figure it is seen that tail vane 2 is deflected in the high speed wake flow of electromotor, According to hydrodynamics and bernoulli principle it is recognised that the thrust direction of electromotor also will deflect.

Comparison accompanying drawing 3,4, Fig. 3 be the structural representation of the two of the embodiment of the present invention, Fig. 4 be the two of the embodiment of the present invention Fundamental diagram.Vector engine is used for fighter plane, and it uses the turbojet engine with after-burner.Fig. 3, figure 4 displays are exactly the structure chart (eliminating above compressor part) of turbojet engine latter half.It can be seen that whirlpool Fuel-injection engine core engine central axial after extend always, after after-burner, have a long circular cone at its tail end Body, it is simply that the tail vane 8 of the present invention, Fig. 1 is shown that the normal condition of tail vane 8, and Fig. 2 is shown that the duty of tail vane.Right According to Fig. 3, Fig. 4 it can also be seen that be designed with rudder fin 9 on tail vane 8, rudder fin 9 is equidirectional with engine center axle, and is perpendicular to The fin of central shaft.The rudder fin 9 that Fig. 3, Fig. 4 show has 4 fins, and angle is uniformly distributed in 4, upper and lower, left and right at 90 degrees to each other Direction.The number of fins of rudder fin 9, form and dimension depend on the factors such as hydrodynamics, the mechanics of materials and deflecting force demand.Root According to hydrodynamics and bernoulli principle it is known that the addition of rudder fin 9, will greatly increase tail vane 8 and bring the deflection of electromotor Power, the active force of this deflecting force the most relatively air-flow and counteracting force are more direct, and strength is bigger, reacts the quickest.Meanwhile, Owing to its position is positioned at engine center axle, there is bigger design space, it is simple to deflection mechanism is installed, relatively on electromotor outer wall Design frame for movement is simpler, and difficulty is lower.

Certainly, as it is shown in figure 5, we can also design by head and the tail interconnective two or more tail vane form more like " tail " tail vane equally, by the more piece tail vane that can deflect continuously, expands " tail effect ", it is thus achieved that balance, smooth inclined Turn power, although such design structure can be extremely complex.

Industrial applicibility

Present invention utilizes active force and counteracting force principle, fluid mechanics principle, bernoulli principle, there is the reason of science Opinion supports.The tail vane of present invention design is positioned at engine center axle, has bigger design space, it is simple to install deflection mechanism, knot Structure is simple, and technical difficulty is relatively low, and being conducive to theory transition is reality.The use of centered rudder fin the most of the present invention, according to fluid Mechanics and bernoulli principle are it is known that in high velocity air, rudder fin can obtain the biggest deflecting force, and this deflecting force wants remote Than active force and the counteracting force of air-flow more greatly, more direct, make aircraft can obtain vector swifter and more violent, quick, efficient and push away Power.
