AERODYNAMIC CONTROL SURFACE (VERSIONS) Russian patent published in 2002 - IPC

FIELD: rocket manufacturing. SUBSTANCE: the aerodynamic control surface consists of a wing and a rotating flap, whose axle is positioned along the trailing edge of the wing. According to the first modification, the flap is made in the form of a space frame, whose two opposite plates are positioned on the two sides relative to the symmetry plane of the wing section and installed in a spaced relation to its surface. The two other plates form side struts linked with the flap axle. According to the second modification, the flap is made in the form of a hollow cylinder with a through axial longitudinal groove. The cylinder axis is positioned in the symmetry plane of the wing section in the flap axle linked with the cylinder bases. The groove width exceeds the maximum thickness of the wing section. According to the third modification, the flap is made in the form of a hollow ball truncated from the poles by parallel planes and installed in the axis passing through its poles in parallel with the planes of sections. The diameter of the inner circle of the flap leading edge exceeds the maximum thickness of the wing section. EFFECT: enhanced efficiency of control of projectiles and rockets at a reduced aerodynamic load on the drive. 3 cl, 9 dwg, 1 tbl
