Abstract
The utility model provides a sheet metal rib structure suitable for a control surface of a small airplane, belonging to the technical field of structural design of the small airplane, and the sheet metal rib structure comprises: rib radials, be located the wing spar cap and the wing rib turn-ups at rib radials edge, wherein a plurality of bosss that form through the punching press of having arranged along length direction on the rib radials be equipped with the diameter on the boss and be not more than the lightening hole or the inspection hole of boss, thereby make the edge formation of boss is higher than the enhancement nest of rib radials. Compared with the sheet metal rib in the prior art, the sheet metal rib structure provided by the utility model has the advantages that the stability and the strength of a rib web are improved, the structural strength is better, and the weight is lighter.
Description
Technical Field
The utility model belongs to the technical field of airplane structure design, and particularly relates to a sheet metal rib structure suitable for a control surface of a small airplane.
Background
The small aircraft is generally a low-speed low-altitude aircraft, the wing profile height of the control surface structure is low, and the aerodynamic load applied to the small aircraft during flight is small. Due to factors such as manufacturing and maintenance costs and structural weight, the wing rib of the control surface structure of the small airplane is usually a sheet metal structure made of aluminum alloy materials, and the manufacturing cost and the production period can be remarkably reduced compared with a composite material structure under the condition of paying minimum weight cost. However, the rib structure of the prior art has low stability and strength.
Disclosure of Invention
It is an object of the present invention to provide a sheet metal rib structure suitable for use in the control surface of a small aircraft to solve or mitigate at least one of the problems of the background art.
The technical scheme of the utility model is as follows: a sheet metal rib structure suitable for use on a rudder surface of a miniaircraft, comprising: rib radials, be located rib flange bead and the rib turn-ups at rib radials edge, wherein a plurality of bosss that form through the punching press of having arranged along length direction on the rib radials be equipped with the diameter on the boss and be not more than the lightening hole or the inspection hole of boss, thereby make the edge formation of boss is higher than the enhancement nest of rib radials.
Furthermore, the folding directions of the rib edge strip and the rib flanging are the same.
Furthermore, the protruding direction of the boss is the same as the folding direction of the rib edge strip or the rib flanging.
Further, the diameters of lightening holes or inspection holes on the boss are reduced from the wide edge to the narrow edge of the rib spoke plate in sequence.
Furthermore, a reinforcing rib passing opening is formed in the rib edge strip.
Furthermore, the sheet metal wing beam structure is manufactured by adopting an aluminum alloy sheet metal through a sheet metal process.
Compared with the sheet metal rib in the prior art, the sheet metal rib structure provided by the utility model has the advantages that the stability and the strength of a rib web are improved, the structural strength is better, and the weight is lighter.

Detailed Description
In order to make the implementation objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to fig. 3, the sheet metal rib structure suitable for a rudder surface of a small aircraft provided by the present invention mainly includes a rib web 1 having a substantially triangular shape, rib flanges 2 located at both sides of the triangular rib web 1, and rib flanges 3 located at one side, wherein the rib flanges 2 and the rib flanges 3 are obtained by a sheet metal bending process. Preferably, in the present invention, the folding directions of the rib cap 2 and the rib flange 3 are the same.
A plurality of bosses are formed by stamping on a longitudinal plane in the rib web 1, and preferably, the boss protrudes in the same direction as the folding direction of the rib flange 2 or the rib flange 3. Processing has the diameter to be not more than the lightening hole 5 and the inspection hole of boss on this boss, lightening hole 5 and inspection hole reduce in proper order (based on fig. 1 visual angle) from rib radials 1's left side broadside to right side narrow side to can form protrusion in rib radials 1's enhancement nest 4 in the marginal position department of boss, and then can improve the stability of web, can lighten structure weight and be convenient for the inspection through lightening hole 5 or the inspection hole of arranging, maintenance equipment passes through.
In addition, in the sheet metal rib structure, the reinforcing rib passing openings 6 are formed in the upper rib edge 2 and the lower rib edge 2, and in the process that the rib edges 2 are connected with the skin through the fasteners, the reinforcing rib passing openings 6 arranged in the spanwise direction of the skin can enable the spanwise reinforcing ribs of the skin to pass through, so that the strength of the skin can be enhanced. The rib flange 3 is connected with the wing spar through a fastener.
The sheet metal rib structure which is manufactured by adopting an aluminum alloy sheet through a sheet metal manufacturing process and is suitable for the control surface of a small airplane is provided with a reinforcing nest 4 and a web flanging 3 which are formed by punching on a rib web 1, so that the stability and the strength of the rib web are improved, the joint of a rib edge 2 and a skin is designed with an opening to a reinforcing rib passing hole, and the sheet metal rib structure is provided with an inspection hole and a lightening hole, so that the weight of a rib is further reduced.
The sheet metal rib structure has the advantages of light weight, mature and reliable manufacturing process, low manufacturing cost and short period. The sheet metal rib structure is successfully applied to a control surface structure of a small general airplane and successfully passes test flight verification, and the sheet metal rib structure can be widely applied to various small airplanes.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
