Abstract
The utility model belongs to the field of aircraft structural design, and in particular relates to a wing rib structure which is used in an aircraft wing box. The wing rib is characterized by comprising webs, edge strips and support posts, wherein the support posts are arranged in parallel side by side; each web provided with a rib is arranged between the ends of very two adjacent support posts; each edge strip penetrates through the ends of the support posts on one side of the corresponding wing rib and the corresponding web between the ends of the support posts. The wing rib has the advantages that fastening pieces are easy to assemble, and the production efficiency is high; meanwhile, a force transfer path of an aircraft wing rib structure is continuous and direct; moreover, the fatigue performance of the wing rib can be improved remarkably.
Description
Technical field
The utility model belongs to aeroplane structure design field, is specifically related to a kind of for the rib structure in aircraft wing box.
Background technology
Existing aircraft rib structure is generally riveted structure, and rib is made up of web and pillar, does some lightening holes on web, and pillar is crisscross to be connected on web, plays the effect that increases rib rigidity.The problems such as this kind of rib structure exists production efficiency low, and fastener assembling is complicated, fatigue property is low, this kind of rib production technology falls behind in addition, lagged behind advanced country in the world large aircraft rib structure design concept.
Utility model content
The purpose of this utility model is: low in order to solve riveted joint rib efficiency of assembling, fastener connects complexity and the low problem of fatigue property and the new technical scheme that designs, in addition, overall aircraft technological level is improved and plays facilitation.
The technical solution of the utility model is: a kind of rib, it is characterized in that, comprise web, edge strip and pillar, described pillar is parallel arranges side by side, between the termination of adjacent struts, be furnished with the web with rib, edge strip runs through the web between strut end head and the termination of rib one side.
Described rib is integrated machine add-on type.
The cross sectional shape of described pillar is flute profile or " work " type.
Web between described adjacent two pillars and strut end head surrounds lightening hole.
Between pillar two end webs of rib structure, maintenance channel is set.
The beneficial effects of the utility model are: the advantage that the utility model has is the advantage that fastener assembling is simple, production efficiency is high, make the power transmission route of aircraft rib structure continuously, directly simultaneously, and can significantly promote the fatigue property of rib.
