Abstract
The utility model discloses a kind of bridging type composite material support arm and the hatch door of this support arm is installed, it is characterized in that, described support arm entirety is made up of composite material, comprise the left support arm (301) that there is muscle in left side, there is the right support arm (302) of muscle on right side, bonding jumper (303), described left support arm (301) is connected by bonding jumper (303) with right support arm (302).And a kind of hatch door wallboard installing described support arm, comprise door panels assembly (1), laminboard layer (2) and composite material support arm assembly (3).Support arm web in-plane stiffness both can be provided, support arm web Out-of Plane Stiffness can be provided again.Meanwhile, door panels adopts Composite Sandwich structure, this lightweight construction and wallboard good rigidity; Again in the bonding one deck thin aluminum top of panels outside, to strengthen the impact capacities such as the sandstone resisted in actual condition.
Description
Technical field
The invention belongs to field of airplane structure, relate to a kind of bridging type composite material support arm and the hatch door of this support arm is installed.
Background technology
At present, door design generally adopts composite structure or metal construction, but to move the support arm provided support to hatch door, due to rigidity requirement, generally have employed metal machine and adds part.In addition, at composite material support structure design aspect, have patent CN201210086731 to devise a kind of support, feature be assembling flexibly, rigidity support can be provided to structure, but above the support that can not be applied to aircraft door.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of bridging type composite material support arm and installs the hatch door of this support arm, while alleviating structural weight, provide the support of twocouese rigidity and improve the impact capacities such as desertification stone to hatch door.
For the technical solutions of the utility model that solve the problem provide a kind of bridging type composite material support arm, described support arm entirety is made up of composite material, comprise the left support arm (401) that there is muscle in left side, there is the right support arm (402) of muscle on right side, bonding jumper (403), described left support arm (401) is connected by bonding jumper (403) with right support arm (402).
Technical solutions of the utility model also provide a kind of hatch door wallboard having installed bridging type composite material support arm, comprise door panels assembly (1), laminboard layer (2) and composite material support arm assembly (3), it is characterized in that, at described laminboard layer (2) connecting portion midline position, composite material support arm assembly (3) according to claim 1 is installed.
Preferably, described door panels assembly (1) is sandwich construction, and described internal layer is composite material skin (101), interlayer position fuse (102), and covering skin is thin lead-covering (103).
A kind of bridging type composite material support arm of the utility model design, both can provide support arm web in-plane stiffness, and can provide again support arm web Out-of Plane Stiffness.Meanwhile, door panels adopts Composite Sandwich structure, this lightweight construction and wallboard good rigidity; Again in the bonding one deck thin aluminum top of panels outside, to strengthen the impact capacities such as the sandstone resisted in actual condition.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail, wherein:
Fig. 1 is part signal;
Fig. 2 is bridging type composite material support arm and the hatch door installing this support arm;
Fig. 3 is door panels assembly;
Fig. 4 is composite material support arm assembly.
Detailed description of the invention
Below the utility model is described in further details
Bridging type composite material support arm and install the hatch door of this support arm, it is characterized in that, described two composite material support arms are symmetrical, web reinforcement, and it connects edge strip end and has depression.
Described composite material support arm, is made up of edge strip, web and rib, and version is as Fig. 1, and the left and right support arm of composite material and composite material bonding jumper array configuration are shown in Fig. 4.
Described composite material support arm assembly and door panels assembly are bolted, and bonding jumper and two support arms are by rivet interlacement, and thin aluminium lamination and wall panel skin are by bonding solidification, and wherein the rib of support arm plays auxiliary posting effect.
Described composite material structural member is shaped by solidification of hot-press tank, and thin aluminium lamination and wallboard are shaped by normal temperature cure.
