Multiple unfolding wing, and its use in an aircraft missile.

摘要

The invention enables an aircraft missile to be fitted with multiple-folding wings in such a way as to reduce the bulk of the missile before use when the wings are retracted. The wing consists of a first primary wing (1) unfolding with respect to the body (2) of the missile along an axis (OY) parallel to the longitudinal axis (OX) of the body. The wing has a secondary wing (3) housed inside the primary wing and pivoting about an axis (OZ) perpendicular to the axis (OY) of the first pivoting and perpendicular to the primary wing. A tertiary wing (5) is also provided, housed inside the secondary wing and pivoted in the same way as the secondary wing at its end in such a way as to increase the lifting surface of the unfolded wing. In the retracted position, the wings are folded against the body of the aircraft missile. Application to military missiles, particularly those flying at supersonic and subsonic speeds. <IMAGE>
