Tail unit for a missile comprising at least one system of two pairs of curved blades, whereof one of the longitudinal edges is fixed to the periphery of a cylindrical body, whereby the blades of the same pair are symmetrical relative to the axis of said body are fixed to the latter in two diametrically opposite zones and have their concavity turned in the same direction about the axis of said body, wherein the orientation of the concavity of the blades of the same pair of blades around the axis of the cylindrical body is opposite to that of the blades of the other pair. The said tail unit makes it possible to improve the stability of the trajectory of the missile on which it is mounted, when a rotary movement is given to the missile.

A tail unit for a missile which is propelled at supersonic speed of the type comprising a system of two pairs of curved blades, each blade having a longitudinal edge connected to the periphery of a cylindrical body, and means located on the missile blades for producing a rotary torque which rotates

A tail unit for a missile which is propelled at supersonic speed of the type comprising a system of two pairs of curved blades, each blade having a longitudinal edge connected to the periphery of a cylindrical body, and means located on the missile blades for producing a rotary torque which rotates the tail unit in flight, each blade being pivoted about a pivot pin integral with the cylindrical body and located in the immediate vicinity of the periphery of the latter and having a curvature which substantially corresponds to that of the body, the length of the circular arc defined by the transverse profile of a blade being between one-quarter and one-half the length of the periphery of a cross-section of the cylindrical body, wherein the orientation of the concavity of the blades of one and the same pair of blades about the axis of the cylindrical body is opposite to that of the blades of the other pair of blades, the pivot pins of the blades of the same pair of blades are located in two diametrically opposite zones on the cylindrical body, and the blades can be folded down onto one another pairwise parallel to the outer surface of the body by rotation about said pivot pins.
