Embodiment Construction

[0013] Referring to the accompanying drawings, a general-purpose aircraft rudder composite wingtip structure, which is a part of the aircraft rudder, is characterized in that the wingtip structure consists of a wingtip fairing 1, a wingtip support rib 2 and an anti-collision light 3 components, wingtip fairing 1 is semicircular in shape, wingtip support rib 2 is in the shape of a closed groove, wingtip fairing 1 is integrally cured and formed by composite materials, and a concave area 4 is designed on the top of wingtip fairing 1 , for installing the anti-collision light 3, the wingtip fairing 1 is covered and glued on the closing notch of the wingtip support rib 2.

[0014] In practice, since the edge of the wingtip support rib 2 is in the shape of a closed groove, it is difficult to form the closing angle on both sides of the edge when it is made of composite materials. Ribs, the first half rib 5 and the second half rib 6, each half rib stretches out a connection area on the...

Abstract

The invention relates to a composite-material wing tip structure for a general aircraft rudder and a manufacturing method thereof. The wing tip structure is one part of an aircraft rudder and is formed by a wing tip radome, a wing tip supporting rib and an anti-collision lamp. The wing tip radome has a semi-circular appearance; the wing tip support rib edge strip has a close-up groove shape; and the wing tip radome is integratedly solidified and formed by using the composite material. A recessed region is designed at the top of the wing tip radome and is used for installing the anti-collisionlamp. The wing tip radome covers and is glued to the close-up groove mouth of the wing tip supporting rib.

Description

technical field [0001] The application belongs to aircraft design technology, in particular to a general-purpose aircraft rudder composite wingtip structure and a manufacturing method. Background technique [0002] Rudders are generally arranged on the trailing edge of the vertical stabilizer of the empennage of a small general-purpose aircraft. The rudder is the rudder surface that maintains the directional stability of the aircraft and is installed on the vertical stabilizer of the empennage. The small general-purpose aircraft wingtip structure in the prior art is positioned at the top of empennage vertical stabilizer, is the part of empennage vertical stabilizer. Usually the wingtip structure is composed of wingtip fairing, wingtip support rib, balance weight and anti-collision light. The shape of the wingtip fairing is semicircular, and the wingtip supporting ribs are closed. The traditional manufacturing method is to stamp and bend the metal sheet, and the weight of t...
