Description
Technical field
The invention belongs to field of airplane structure, specially a kind of big height rib structure.
Background technique
Current in-service aircraft rib mainly has metal rib and composite material rib.
Composite material rib mainly has cellular sandwich rib and laminate rib.Cellular sandwich rib mainly by inner panel,
Outer panels, honeycomb core and glue film composition are glued by glue film with honeycomb core as inner panel and outside integral.Cellular sandwich rib
It is primarily adapted for use in the higher box section of aerofoil profile, such as B787 aircraft vertical fin box section root rib, such rib structure globality is high, once
Molding, structure is light, at low cost, but if aerofoil profile is very high, rib web meeting unstability can only guarantee web by thickening mode
Not unstability thus brings the increase of weight.Laminate rib is generally closed glue film and is formed by rib ontology, angle stiffener.The wing
Rib ontology is glued with angle stiffener by glue film integral.Laminate rib applies in general to the lower box section of aerofoil profile, high aerofoil profile
When, using laminate rib web can unstability, for solve web destabilization problems, can only web thicken or encryption angle stiffener, from
And construction weight is caused to increase, cost increases.
Metal rib main organic plus rib and metal plate rib.Machine adds rib good integrity, large carrying capacity, as be applied to
The big structure position of load.To guarantee that unstability does not need to thicken web web and stud is reinforced, so that construction weight be brought to increase
Add, lower with opportunity plus rib stock utilization, cost is compared with other ribs height.Metal plate rib is mainly used in wing lower, load
Lotus is compared with capsule section, and such rib is at low cost, lightweight construction, but it is strong to design shape, is easy to produce fatigue crack, newly grinds winged
The few application metal plate rib structures of machine box section.
Summary of the invention
Task and purpose of the invention: a kind of big height rib structure is proposed.Mainly solve big aerofoil profile rib structure design
Problem.Rib is all overall structure at present, if aerofoil profile is big, rib web is easy unstability, will be increased to solve destabilization problems
It adds thickness or reduces grid size.Rib is divided into three parts rib upper body, rib lower body and rod assembly by the present invention
Three parts composition.Rib upper body is connected with rib lower body by rod assembly integral.
Technical solution
A kind of big height rib structure, by rib upper body (3), rib lower body (4) and rod assembly (5) three parts group
At；Rib upper body (3) and rib lower body (4) are connected integral by rod assembly (5)；Rib upper body (3) and box section
Wainscot (1) connection；Rib lower body (4) is connect with box section lower wall panels (2).
Rib upper body (3) is metal structure；Rib upper body (3) is provided with notch, and the notch is provided with box section upper wall
Plate (1) stringer and rib upper body (3) intersection, it is ensured that box section wainscot (1) stringer passes through；Box section wainscot (1) stringer is logical
Cross place, rib upper body (3) by sink climb in box section wainscot (1) stringer connect with box section wainscot (1) it is integral；The wing
Rib upper body (3) and box section wainscot (1) stringer junction, rib upper body (3) are designed to shark's fin shape；Rib upper body
(3) there is connector far from design at box section wainscot (1), for the connection with rod assembly (5).
Rib lower body (4) is metal structure, and surrounding structure connection relationship is identical as rib upper body (3).
The rod assembly (5) is made of rod head, pull rod and locking device for locking the body of rod and connector, draws
Knock-off joint is metal structure, and pull rod is composite structure or metal structure, spiral shell in rod head external screw thread and bar body
Line connection, by rotating adjusting yoke total length.
The locking device is a pair of of tooth form retaining ring.
Technical effect
Rib of the present invention is made of rib upper body, rib lower body and rod assembly three parts.Due to wing height, it is divided into
Three parts are conducive to improve stock utilization, reduce production cost, while three parts can be filled according to respective bearing behavior
Divide detailed design, to mitigate construction weight.
Rib upper body and rib lower body use metal machining process forming, can be effective compared with composite structure
Connect with box section wainscot, lower wall panels, to improve support to box section wainscot, lower wall panels, improve box section wainscot, under
Siding Instability value, to mitigate construction weight.
Rib upper body and rib lower body are attached by rod assembly, and the carrying that can give full play to pull rod is special
Property, to mitigate construction weight, reduce production cost.Composite material rib can not carry out this kind of organization plan and be designed.If
Using conventional metals rib scheme, rib web is supported by machining column, stock utilization is low, high production cost, increasing
Add construction weight.
