Airplane pneumatic component gap blocking structure

Abstract

The invention discloses an airplane pneumatic component gap blocking structure which comprises a first section of front part upper skin, a first section of front part lower skin, a second section of front part upper skin and a second section of front part lower skin, and a first blocking plate is installed between the first section of front part upper skin and the first section of front part lower skin through a first section of front part end rib; a second blocking plate is mounted between the second section of front part upper skin and the second section of front part lower skin through a second section of front part end rib, the first blocking plate and the second blocking plate are the same in shape and structure and different in size, and the first blocking plate and the second blocking plate are each of a semi-oval structure; a first tubular extrusion deformation body is arranged on the first blocking plate, a first extrusion deformation cavity is formed in the first extrusion deformation body, a second tubular extrusion deformation body is arranged on the second blocking plate, and a second extrusion deformation cavity is formed in the second extrusion deformation body. Compared with a traditional rubber plate blocking plate, the blocking structure has the advantages of being small in pneumatic influence, good in blocking effect and light in weight.

Description

technical field [0001] The invention relates to the field of aircraft design, in particular to a gap sealing structure for aircraft aerodynamic components. Background technique [0002] Modern aircraft are designed to improve the high-angle flight characteristics or the low-speed characteristics of the aircraft, and the front flap that can be deflected downward is often provided on the leading edge of the wing. Among the aircraft in service, the length of the leading edge of the wing on one side of the small aircraft has reached about 1 meter, and the leading edge of the wing of the large aircraft is longer, and such a long front flap requires multiple sets of actuators to control its rotation , and for the control of such key pneumatic components, a redundant control design scheme will be adopted in the control logic. It is precisely because of this redundant design that it has brought great trouble to the design of the front placket. [0003] If the front flap is not des...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem of mutual friction between adjacent sections or inconsistency between the left and right gaps between adjacent sections in the above-mentioned section design and section control of the front flap. Adjacent front flaps rub against each other without damage, and can ensure that there is no gap between adjacent front flaps
