Upper covering, short limb bottom covering and short limb side skin constitute tank bay.
In this application, covering, short limb bottom covering and short limb side skin are that composite material is made on the short limb.
In this application, covering is equipped with installation lid, covering in the installation lid and the short limb on the short limb
It is bolted, is covered in installing port and offered a mouthful frame, maintenance lid is installed on the mouth frame.
In this application, accessory plate is set on the covering of the short limb bottom and safeguards lid.
In this application, short limb bottom covering includes inner panel, outer panels, reinforcer and honeycomb, the inner panel and
Outer panels are arranged in parallel and connect with reinforcer, and the honeycomb is filled between the inner panel and outer panels.
In this application, the section of the reinforcer is C-shaped, and opening is directed away from accessory plate maintenance lid side
To.
In this application, installation settings foot nest and handle on the short limb side skin.
Present invention also provides a kind of helicopter, the helicopter includes any going straight up to tank bay as above
Machine short limb structure.
The external arrangement of fuel tank may be implemented in the helicopter short limb structure with tank bay of the application, and has apparent
Weight loss effect, by using fuselage short limb integrated design, using fuselage side skin as the inside panel of short limb, Quan Jike is with loss of weight
About 20kg.
Detailed description of the invention
In order to illustrate more clearly of technical solution provided by the present application, attached drawing will be briefly described below.It is aobvious and easy
Insight, drawings discussed below are only some embodiments of the present application.
Fig. 1 is the nacelle structure schematic diagram of one embodiment of the application.
Fig. 2 is stressed-skin construction figure on the short limb of one embodiment of the application.
Fig. 3 is the short limb bottom stressed-skin construction figure of one embodiment of the application.
Fig. 4 is the short limb bottom covering cross-sectional view in the application.
Fig. 5 is the maintenance channel main view of one embodiment of the application.
Specific embodiment
To keep the purposes, technical schemes and advantages of the application implementation clearer, below in conjunction in the embodiment of the present application
Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.
In the description of the present application, term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "top", "bottom", "inner", "outside" is that orientation based on the figure or position are closed
System is merely for convenience of description the application and simplifies description, rather than the device or element of indication or suggestion meaning must have
Specific orientation is constructed and operated in a specific orientation, therefore should not be understood as the limitation to the application protection scope.
As shown in Figure 1, the technical solution of the helicopter short limb structure with tank bay of the application is short limb bulkhead
Fuselage short limb integration bulkhead 1 is used for 4, it is internal with holonmic space to guarantee to cancel longitudinal rib structure, and outside uses 3
Covering 2, short limb side skin 4, short limb bottom covering 3 connect bulkhead 1 on block composite material skin, that is, short limb, and each covering is equal
There is the side of bending, can be connected with other coverings or bulkhead, it is more to be formed together tank bay, landing gear compartment etc. with fuselage skin 5
A short limb bay section.
As shown in Figures 2 and 3, to provide the installation of fuel tank, fuel tank is set on covering on short limb, lid 21 is installed, by more
A bolt is connect with covering 2 on short limb.Mouthful frame 22 and the setting maintenance lid 23 at mouth frame 22 are opened up in installation lid 21, are passed through
Multiple bolts are connect with installation lid 22.Accessory plate is set on short limb bottom covering 4 and safeguards lid 31, passes through multiple bolts and bottom
Portion's covering connection, to realize the installation and maintenance of fuel tank.
Such as Fig. 4, deformation of the lid 21 at maintenance lid 23 is installed to reduce fuel tank, installation lid increases aluminium alloy mouth frame
22, lid 21 is installed with fuel tank by multiple bolts and is connect.
The deformation at lid 31 is safeguarded to reduce short limb bottom covering 4 in accessory plate, and preforming 4 c-type composite materials add
Strong part 34 is arranged honeycomb and constitutes bottom covering 4 between c-type reinforcer 34 and inside/outside panel, reinforcer 34 and short limb bottom are covered
Skin 4 carries out secondary co-curing together.
Such as Fig. 5, to provide helicopter maintenance channel, in the outside installation settings foot nest 41 and handle 42 of short limb side skin 4.
Foot nest 41 and short limb side skin 4 pass through rivet interlacement.Handle 42 is to increase iron clad 42 on short limb at 2 upper opening of covering.
The external arrangement of fuel tank may be implemented in the helicopter short limb structure with tank bay of the application, and has apparent
Weight loss effect, by using fuselage short limb integrated design, using fuselage side skin as the inside panel of short limb, Quan Jike is with loss of weight
About 20kg.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims
It is quasi-.
