Wing arrangement as well as a missile

Abstract

A wing arrangement (10), which can be pushed onto a structure, such as a missile, and which includes a number of tubular segments (14) and a number of wings (16) which are arranged on the tubular segments (14). In order to allow the wing arrangement (10) to be pushed on over a missile, it includes structure for expandable connection of the tubular segments (14). Also provided is a missile having a wing arrangement (10) of that kind.

Description

BACKGROUND OF THE INVENTION [0001] 1.Field of the Invention [0002] The invention relates to a wing arrangement, which can be pushed onto a structure, such as a missile, and has a number of tubular segments and a number of wings which are arranged on the tubular segments, and to a missile having a wing arrangement of this kind. [0003] It is known for missiles to be provided with wing arrangements in order to allow them to be steered and controlled better. Wing arrangements allow high lateral acceleration forces to be produced aerodynamically, allowing a missile to change direction quickly. In order not to adversely affect the agility of a missile, care must be taken to ensure that the wing arrangements do not lead to serious disturbances on the outer skin of the missile since this would increase the aerodynamic drag and, in some circumstances, the weight of the missile as well, and would thus reduce its maximum speed.

AI Technical Summary

Benefits of technology

"The present invention relates to a wing arrangement for missiles that can be pushed onto the missile, even if its external diameter varies. The wing arrangement has tubular segments and wings that are arranged on the tubular segments. The invention provides means for expandable connection of the tubular segments, which allows the wing arrangement to expand and fit snugly over a missile without adding stress or aerodynamic drag. The wing arrangement is designed to be strong and robust enough to withstand high speeds and maneuverability, and can be produced without additional areas that may increase weight. The invention also allows for a wing arrangement that can be fixed to a missile at high speeds to ensure proper positioning and flying characteristics."

Problems solved by technology

Clamping connections such as these are, however, not suitable for agile missiles since clamping screws which are always required for these clamping connections project into the flow around a flying missile.

This increases the aerodynamic drag of a missile, and causes a deterioration in its flying characteristics.

Furthermore, the stress which is exerted on the missile by firmly tightening the clamping screw after attachment of the clamping connection has a negative effect on the missile.

This can result in cracks in the material, and in further damage associated with them, in this region, both in the case of the missile itself and in the case of the wing arrangement.
