Abstract
The utility model provides a kind of aircraft conversion deckle board, including siding (1) and fit in deckle board on the inside of siding (1), the deckle board is by upper half reinforcing frame (2), lower half reinforcing frame (4) and positioned between the two connector (3) form, wherein described lower half reinforcing frame (4) both ends end face is arranged in parallel, and one end end face is bonded setting with airplane floor, the other end face position is beneficial to assembling selection according to deckle board stress situation and part disengaging hatch door are convenient, the lower half reinforcing frame (4) is pushed into along airplane floor from fuselage medial side and is connected to each other by connector (3) and the upper half reinforcing frame (2).Aircraft conversion deckle board provided by the utility model, using horizontal separation face, reinforcing frame is laterally pushed into, auxiliary or secondary cut face need not be increased, do not influence original structure stringer and annex, it is not required that destroy siding and change aerodynamic configuration and increase frock, cost is low, simple and practicable, and is hardly damaged.
Description
Technical field
The utility model belongs to field of airplane structure, and in particular to a kind of aircraft conversion deckle board.
Background technology
A kind of aircraft conversion is reequiped on the crate of flown for years, and one kind is to shape or obtaining seaworthiness
Repacking designs new aircraft, that is, basic aircraft on the aircraft of card.Special Aircraft is typically all what is reequiped on ripe platform,
Risk can be reduced, reduce the lead time.Repacking for airframe structure, it is not necessary to former siding is decomposed, so as not to it is pneumatic outer
Shape changes resistance and increases performance reduction and need substantial amounts of mould, and how added cost, assemble what is strengthened in subcircular fuselage
Frame, as integrated machine plus deckle board, decompose face obtain it is bad, may result in fresh processed frame can not assemble.
Utility model content
The purpose of this utility model is to provide a kind of aircraft conversion deckle board, at least one of the prior art is overcome or alleviated by
Drawbacks described above.
The purpose of this utility model is achieved through the following technical solutions：A kind of aircraft conversion deckle board, including siding and patch
Together in the deckle board on the inside of siding, which is formed by upper half reinforcing frame, lower half reinforcing frame and positioned at connector between the two,
Wherein described lower half reinforcing frame both ends end face is arranged in parallel, and one end end face is bonded setting, the other end with airplane floor
Endface position is beneficial to assembling selection according to deckle board stress situation and part disengaging hatch door are convenient, and the lower half reinforcing frame is along aircraft
Plate is pushed into from fuselage medial side and is connected to each other by connector and the upper half reinforcing frame.
Preferably, the upper half reinforcing frame and the connector contact plane are parallel with airplane floor.
A kind of beneficial effect of aircraft conversion deckle board provided by the utility model is, before structural intergrity is met
Put, the deckle board parting surface division having the advantages of simple structure and easy realization, enables reinforcement deckle board to match somebody with somebody into frame flat, and do not influence
Original structure stringer and annex, it is not required that to destroy siding and change aerodynamic configuration and increase frock, cost is low, simple and practicable, and not
It is fragile.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model aircraft conversion deckle board；
Reference numeral：
1- sidings, 2- upper half reinforcing frame, 3- connecting plates, 4- lower half reinforcing frames.
Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Described reality
It is the utility model part of the embodiment to apply example, instead of all the embodiments.Below with reference to the embodiment of attached drawing description
It is exemplary, it is intended to for explaining the utility model, and it is not intended that limitation to the utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
The aircraft conversion deckle board to the utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of aircraft conversion deckle board, including siding 1 and the deckle board for fitting in the inner side of siding 1, the deckle board
It is made of upper half reinforcing frame 2, lower half reinforcing frame 4 and the connector 3 for docking both.For aircraft conversion reinforcing frame
Assembling, is docked according to traditional normal direction, since the stops such as stringer and annex can not be pushed into frame after the past in fuselage compartment
Plane is docked, and using lateral push-in, and can not gone because the highest at deckle board normal separation clicks through.And then horizontal separation face is used,
4 both ends end face of lower half reinforcing frame is arranged in parallel, and one end end face is bonded setting, the other end face position with airplane floor
Put according to deckle board stress situation and part disengaging hatch door it is convenient be beneficial to assembling choose, the lower half reinforcing frame 4 along airplane floor from
Inboard is laterally pushed into and is connected to each other by connector 3 and upper half reinforcing frame 2, wherein upper half reinforcing frame 2 and 3 phase of connector
Contact plane also uses arrangement parallel with airplane floor.
The installation step of the utility model aircraft conversion deckle board is described below.
It with the plane that is in contact at floor is lower parting surface to take deckle board first, deckle board stress level it is relatively low and easy to assembling and
Parting surface, and parting surface edge setting parallel with ground plate axis on this are taken as at part disengaging hatch door.Fit-up gap has been stayed,
Then upper numerical control each process and be surface-treated, Non-Destructive Testing etc., and it is clear to enter the carry out such as director purlin, annex to deckle board
Reason.Secondly each section of reinforcing frame is pushed into along floor from fuselage medial side, positioned and fixed.Finally will up and down using connector 3
Two reinforcing frames connect together, and ensure bonding strength, make complete deckle board.
The above, is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with described
Subject to scope of the claims.
