Description
Technical field
The present invention relates to field of airplane structure, and in particular to be that a kind of motor-driven aircraft store mounting point is close
Sealing mechanism.
Background technology
Modern invisbile plane is increase voyage and bullet-loading capacity, and increase the flexibility for carrying ammunition and combat duty, it is necessary to
All kinds of ammunitions, gondola, and auxiliary fuel tank are carried using the store mounting point under wing or fuselage.The process of combat duty is performed in aircraft
In, to ensure mobility and Stealth Fighter, it is necessary to by auxiliary fuel tank together with hanger jettisoning before region of war is entered.In addition,
After aircraft has launched plug-in ammunition, it is also desirable to jettisoning hanger, to reduce rebecca reflective surface area, recover totally pneumatic
Profile.For mounting hung rack, the covering at aircraft store mounting point leaves an opening, and this aperture area is larger, stealthy to aircraft gentle
There is adverse effect in dynamic performance；
Present part aircraft using one piece can the lid of artificial unloading sealed come the opening to covering at store mounting point.Fly
When machine is without using store mounting point, lid is installed aboard to seal the opening of covering at store mounting point.In aircraft utilization store mounting point
When, the lid at the store mounting point is removed, then mounting hung rack.The shortcoming of this method is：After hanger jettisoning, without mouth
Lid is sealed to the opening on covering at the store mounting point, and the opening is unfavorable to the pneumatic and Stealth Fighter of aircraft.Patent of invention
201410279843.X describes a kind of sealing mechanism of stage clip driving, and the program is primarily present 3 shortcomings：(1) program according to
Automatic closing is realized by the dead point of four-bar mechanism, but open position is got too close in dead point, and easily producing sealing plate can not close
The failure closed；(2) after sealing mechanism is opened, two sealing plates are received into shell to both sides respectively, it is therefore desirable in shell
Reserved enough spaces, cause the area of plane of whole sealing mechanism larger, it is necessary to reserve larger opening on covering, and cover
Skin can have a negative impact as the important force transferring structure of aircraft, larger opening to aircraft structure strength；(3) sealing mechanism is pacified
After dress, whole sealing mechanism is all exposed to the outside of the theoretical profile of aircraft, and the pneumatic and stealthy meeting profile of aircraft can be caused
A certain degree of destruction.
The content of the invention
It can seal covering at aircraft store mounting point the present invention seeks to the aircraft that hanger can be delivered for equipment there is provided one kind and open
The sealing mechanism of mouth, sealing mechanism should be able to meet following requirement：(1) it can remain on, be thrown in hanger after mounting hung rack
It is automatic after putting to close, and remain closed mode in the flight course after hanger is delivered；(2) structure and principle are tried one's best letter
It is single, aircraft skin outer surface is not protruded from as far as possible, and sealing mechanism influence pneumatic to aircraft and Stealth Fighter is preferably minimized；
(3) area of plane is as far as possible small, and the influence by sealing mechanism to aircraft structure strength is preferably minimized.
The problem of in order to solve in the presence of background technology, it includes and offers hanger hole 12, institute on shell 1, the shell 1
The sealing plate 9 that can be rotatably assorted with it is separately installed with the outside bottom surface for stating shell 1, the sealing plate 9 is located at hanger hole 12
Both sides, the medial surface of the shell 1 is provided with the stepper motor 2 of the driving rotation of sealing plate 9 and positioned at the both sides of hanger hole 12
Correlation infrared sensor 4；
Described stepper motor 2 is fixed on shell 1 by support 13, and its piston shaft end is provided with active angular wheel 3,
The side of the active angular wheel 3 is provided with the driven angular wheel 8 for engaging cooperation, the tooth of the driven angular wheel 8
Rotating shaft 6 is installed, one end of the rotating shaft 6 is spun by nut 7 to be fixed on driven angular wheel 8, and its other end is worn in wheel bore
Cross shell 1 and spun by nut 7 and is fixed on sealing plate 9.
Nut groove is offered on described sealing plate 9, after nut 7 is screwed, the end of the nut 7 and the side of nut groove
Flushed along place, packing material 10 is provided with described nut groove, the lateral surface of the packing material 10 is flushed with nut groove.
One layer of bushing 5 is provided between described rotating shaft 6 and shell 1.
As a result of above technical scheme, the invention has the advantages that：It is simple in construction, it is easy to use, install
During hanger, sealing plate is opened by a switch by ground staff, sealing plate will remain in open mode afterwards, hanger is delivered
Afterwards, sealing mechanism will turn off, using more convenient；
Due to that need not reserve the space of sealing plate inside the housing, the planar dimension of sealing mechanism and corresponding covering are opened
Mouth is smaller, just slightly larger than hanger size, influences small to aircraft structure strength；
After sealing mechanism is closed, only sealing plate and sub-fraction shell protrudes from aircraft outer surface, to aircraft aerodynamic performance
Influence small with Stealth Fighter；
Sealing mechanism is only installed aboard by modes such as rivetings, independently of aircraft other systems, will not be to other
System produces interference.
