ADAPTIVE PNEUMATIC WINGS FOR FLYING DEVICES WITH FIXED WINGS

摘要

An adaptive pneumatic wing, partly inflatable with compressed air and changeable in its shape, with a leading edge (3) and a trailing edge (4) with a box shaped spar (1), characterised in that between the leading edge and the spar at least one module (2), inflatable with compressed air and changeable in its shape by the application of compressed air, is built in and is fastened at least indirectly to the spar, between the trailing edge and the spar at least one module (2) inflatable with compressed air and changeable in its shape by the application of compressed air, is built in and is fastened at least indirectly to the spar, each module extends over the entire length of a wing half and is constructed from a multiplicity of plates (7), parallel within a small angle to each other, compressed air actuated means, to move the plates essentially parallel to each other, an airtight upper skin (5), which is fastened to the plates at suitable intervals, an airtight lower skin (6), which is fastened to the plates at suitable intervals, a connecting surface, which at the wing tips joins the upper skin and the lower skin, and is joined airtight at the borders of each module to the plate at its end, each module is sealed airtight both against the outside and also against the adjacent module and joined via a compressed air line to a compressed air feed, a foil (10) is present, which defines the aerodynamic outer surface of the wing and is joined both to the spar and also, via plates (11) extending along the wing with hinge joints (14), to the modules, between the foremost plate (7) of the foremost module (2) and the leading edge formed by the foil at least two tubes (15, 16) are laid in, extending along the wing, which are manufactured from an airtight, flexible, but low-stretch material and can be individually inflated with compressed air. 1909 כ' באלול התשס" ג - September 17, 2003
