A wing which is extendable from an airborne body. The wing includes a base spar which is actuatable through the operation of a power element, a nose spar which has one of the end sections thereof supported for pivotal movement about a bearing axis located on the airborne body and at least one lamella or sheet metal element which extends at least approximately in parallel with the nose spar in every angular position thereof, which has one end section thereof pivotably supported on the base spar by means of a lamella axis. A stabilizing element is supported for pivoting about a connecting axis at the second end section of the nose spar which is distant from the first end section, and extends through contact or positioning elements at the second end section of the at least one lamella element distant from the associated lamella axis.

Wing extendable from an airborne body

An unfoldable wing which is extendable from an airborne body, wherein the wing includes a nose spar which has one end segment thereof pivotable about a bearing axis which is located on the airborne body, and a motive arrangement equipped with an energy accumulator or storage for effectuating the extension of the nose spar about the associated bearing axis. On the airborne body there is provided a base spar having a first end segment in proximity to the bearing axis for the nose spar, and with the base spar being oriented at least approximately parallel with the longitudinal axis of the airborne body, whereby the base spar is displaceable along its longitudinal direction and is operatively connectable or, essentially, operatively connected with the energy accumulator and with the nose spar for effectuating the extension of the nose spar. The airborne body, there is required only a relatively small amount of space for the base spar, so as to allow for a construction of the unfoldable wing for an outward extension from the airborne.

A projectile, an airborne body or a missile, such as an article of ammunition, having extendable wings, whereby a wing covering is provided to extend between a front spar which is extendable through the action of a power element, and a rear spar which is retractable with its outer end against the front spar, as well as providing for a specially adapted power element for this purpose. The power element has one end thereof engaging at the front spar and has its opposite end engaging against a slider which is latched to the projectile so as to be supported thereon for displacement along the longitudinal direction, and wherein the rear spar has its inner end pivotable in front of the slider in the direction of displacement thereof, and upon the slider being unlatched, is pivotable further by the slider under the action of the power element for effectuating the tensioning of the wing covering.
