Description
Technical field
The present invention relates generally to aviation field technology, and in particular to a kind of aircraft, more particularly to a kind of T-shaped empennage and match somebody with somebody
There is the aircraft of T-shaped empennage.
Background technology
T-shaped empennage is a kind of tectonic type of empennage, according to the layout relationship of tailplane and vertical tail, other tails
Wing tectonic type also includes：H types layout, V-type tail layout and many vertical tails layout etc..And the specific layout of T-shaped empennage
For：Tailplane is arranged on aircraft vertical stabilization.The advantage of T-shaped empennage layout is that tailplane is smaller by fuselage flow field,
It is usually used on transporter, with stronger stationarity, so the aircraft that present application is introduced is primarily referred to as transporter.
But in the T-shaped empennage of conventional airplane layout, tailplane is still very big by fuselage flow so that level
The trim ability of empennage is given a discount；Meanwhile, unreasonable, Redundancy Design mistake is designed in the junction between tailplane and vertical tail
It is many, it have impact on the efficiency of tailplane.
Utility model content
In view of drawbacks described above of the prior art or deficiency, the utility model purpose are to provide a kind of T-shaped empennage and matched somebody with somebody
There is the aircraft of T-shaped empennage.
Concrete technical scheme includes：A kind of T-shaped empennage, including vertical tail and tailplane, the vertical tail and water
Horizontal tail wing junction interlocks layout, and the front end of tailplane is arranged on the rear of the front end of vertical tail, the rear end of tailplane
Protrusion forms smooth arc between the rear of the rear end of vertical tail, the front end of tailplane and the front end of vertical tail top surface
The transition of shape face.The design reduces interfering with each other for vertical tail and tailplane flow field, increase vertical tail and tailplane
Efficiency.
In the connected mode of traditional vertical tail and tailplane, to ensure the connection of vertical tail and tailplane
Two surfaces up and down of intensity, vertical tail and tailplane, which are respectively formed, to be fixedly connected, and due to link position problem, is resulted in vertical
The top of fin can expose one piece of projection in tailplane upper surface, so that the upper surface of tailplane can not form entirety
Smooth flat.In traditional structure, if making vertical tail be only connected with the lower surface formation of tailplane, elimination of level empennage
The projection of upper surface, just occurs the problem of both junction structural strengths are weaker, is easily caused horizontal tail loosening.
Because tailplane upper surface is rough, interference of the flow field to tailplane can be increased；In order to solve this problem,
It is the integrally formed T-shaped beam of injection during making, inside tailplane and vertical tail, is integral type structure, greatly
The intensity enhanced between tailplane and vertical tail, enhance the stability of tailplane.Realizing will be described vertical
The top surface of empennage is fixedly connected with the lower surface of the tailplane, and the upper surface of tailplane is the knot of smooth streamline surface
Structure.The protrusion problem of tailplane upper surface is solved, the flow field for significantly increasing tailplane is stable, improves horizontal tail
The efficiency of the wing.
The technical solution of the utility model also includes：Aircraft equipped with T-shaped empennage, including fuselage, in addition to above-mentioned T-shaped tail
Difference in height between the root of the wing, the peak of the top surface of the fuselage and the vertical tail is fuselage height h, described vertical
The height of empennage is D, and the difference in height between vertical tail and fuselage is D-h, is influenceed by fuselage flow field, tailplane is typically carried
For the negative new line lift opposite with lift, when meeting D-h ＞ 1/3D relation between D, h, D-h, negative lift subtracts than before
Lacked 50%, when D-h is close to D, negative lift only have before 10%.But structural strength is constrained to, D-h can not be excessive, greatly
In, it is necessary to carry out extra reinforcement to structure, increasing weight after D, and efficiency will not increase too much, and comprehensive income is not high, meanwhile,
If during the excessive height D more than vertical tail of D-h value, being also easy to cause the unstability of structure, aeroelasticity occur and ask
Topic, therefore, should meet between D, h, D-h：D ＞ D-h ＞ 1/3D.
A kind of preferred technical scheme is：Between the root of the peak of the top surface of the fuselage and the vertical tail
Difference in height is h, and the height of the vertical tail is D, D-h=1/2D.
Another preferred technical scheme is：Between the root of the peak of the top surface of the fuselage and the vertical tail
Difference in height be h, the height of the vertical tail is D, D-h=2/3D.
The top surface of the fuselage is streamline surface, and the minimum point of fuselage top surface is located at its connection with vertical tail root
Place.The minimum point of fuselage top surface is located at the rearmost end of fuselage, and it is laminar flow in the flowing of aircraft surfaces to make air, it is to avoid produced rapid
Stream, aircraft suffered resistance in flight course is minimum, and aircraft flight stability is best.
Described tailplane is symmetrical airfoil.Camber line is symmetrical above and below the tailplane of symmetrical airfoil, obtains optimal behaviour
Vertical effect, in addition, resistance of the symmetrical airfoil in all aerofoil profiles is minimum, and symmetrical airfoil has when tackling aircraft stall
Good performance.
The beneficial effects of the utility model are：
1. the layout that T-shaped empennage of the present utility model is interlocked using tailplane and vertical tail is set, level is simplified
The Redundancy Design of junction between empennage and vertical tail, adds the area contacted between vertical tail tailplane,
Interfering with each other for vertical tail and tailplane flow field is reduced, the efficiency of tailplane and vertical tail is added.
2. being influenceed by fuselage flow field, tailplane generally provides the negative new line lift opposite with lift, as D, h, D-h
Between meet：During D-h ＞ 1/3D relation, negative lift reduces 50% than before, when D-h is close to D, before negative lift only has
10%.But structural strength is constrained to, D-h can not be excessive, more than, it is necessary to carry out extra reinforcement to structure, increase is heavy after D
Amount, and efficiency will not increase too much, and comprehensive income is not high, meanwhile, if during the excessive height D more than vertical tail of D-h value,
It is also easy to cause the unstability of structure, Aeroelastic Problems occurs, therefore, the length of vertical tail meets D ＞ D-h ＞ 1/3D
Proportioning, the vertical tail of this length ensure that tailplane, away from fuselage flow field, adds the efficiency of tailplane and matched somebody with somebody
Flat ability.
3. tailplane is shaped as smooth streamlined in upper surface, the air-flow is set to form laminar flow in the top of tailplane,
Avoid air-flow from turbulent flow occur, equally add horizontal tail efficiency.
4. the minimum point of fuselage top surface is arranged on the rearmost end of fuselage, the stabilization in aircraft flight is considerably increased
Property.
5. tailplane is symmetrical airfoil, the air drag of tailplane is greatly reduced, while enhancing the mistake of aircraft
Fast performance.
It is integral type structure 6. being the integrally formed T-shaped beam of injection inside tailplane and vertical tail, greatly enhancing
Structural strength between tailplane and vertical tail, so that vertical tail is only connected with the lower surface of tailplane, water
The horizontal tail wing is also not in loosen.
