Winglet connecting device for aviation aircraft

Abstract

The invention discloses a winglet connecting device for an aviation aircraft. The device comprises a wingtip support and wingtip connecting units, wherein each wingtip connecting unit comprises an embedded block, a connecting rod and a holddown spring; the wingtip support adopts a half-cylinder body; the wingtip support is fixed on a wing end through a plane of a side part on one side of the half-cylinder body; a plurality of grooves used for mounting the wingtip connecting units are formed in a cylindrical surface on the other side of the half-cylinder body; a non-circular embedded block groove is formed in one side wall surface in a groove; a blind hole is formed in the other side wall surface in the groove; the embedded block can be clamped in the embedded block groove in a matching manner; a plurality of dividing plug sockets uniformly distributed along a circumference are formed in the outer end surface of the embedded block; one end of the connecting rod is used for being connected with a winglet; one side surface of the other end part of the connecting rod forms a plane; a plug is arranged on the other side surface of the other end part of the connecting rod; one end of thehold-down spring is positioned in the blind hole; the other end of the hold-down spring is propped against the plane on one side of the connecting rod. The device is small in occupied space and low inweight and has more adjustable angles.

Description

technical field [0001] The invention relates to a winglet connection device, which belongs to the field of aviation vehicle design. Background technique [0002] Winglets are used for subsonic aircraft, mainly including civil aviation passenger aircraft, military transport aircraft, aerial refueling aircraft, early warning aircraft and unmanned aerial vehicles. In the subsonic aircraft in the world today, some winglets are set up to improve the flow of the airflow in the span of the wing, reduce the induced drag of the wing, reduce fuel consumption, and improve economic performance. [0003] But not all subsonic aircraft use winglets. The first is the cost issue. The installation of winglets increases the design and manufacturing costs, and the installation of winglets on passenger aircraft will cost hundreds of thousands of dollars. Secondly, the aircraft performs various tasks, and the winglets can only exert their advantages to the greatest extent during the cruise proc...
