Abstract
A guided projectile includes a body and a deployable wing in which the deployable wing is coupled to and enclosed by the body. A linear distance from the leading edge to the trailing edge of the wing defines a chord line that, in the stowed position, forms an angle with a plane containing the chord line and extending parallel to a longitudinal dimension of the wing in a deployed position.
Claims19
A projectile comprising:
- a nose;
- a body;
- a tail boom opposite the nose along a longitudinal axis of the body;
- a plurality of stabilizers extending from a mount on the tail boom;
- and
- a deployable wing coupled to the body at a pivot, wherein:
- rotation about the pivot moves the deployable wing from a stowed position to a deployed position;
- a linear distance from a leading edge to a trailing edge of the deployable wing defines a chord line;
- a reference plane is defined, in the deployed position, by the chord line and a longitudinal dimension of the deployable wing;
- the deployable wing is enclosed by the body in the stowed position;
- and
- the chord line forms an acute angle with the reference plane in the stowed position;
- wherein a longitudinal plane extends along the longitudinal axis of the body, and wherein a lateral plane extends transversely to the body and perpendicularly to the longitudinal plane, and wherein the pivot defines a rotational axis having a first projection in the lateral plane forming an first acute angle with respect to the longitudinal plane and a second projection in the longitudinal plane forming a second acute angle with respect to the lateral plane.

A projectile comprising:
- a nose;
- a body, wherein a longitudinal plane extends along a longitudinal axis of the body, and wherein a lateral plane extends transversely to the body and perpendicularly to the longitudinal plane;
- a tail boom opposite the nose along the longitudinal axis of the body;
- a plurality of stabilizers extending from a mount on the tail boom;
- a deployable wing extending longitudinally from a proximal end to a distal end and extending laterally from a leading edge to a trailing edge, the deployable wing comprising:
- a lug at the proximal end of the deployable wing;
- a lug bore extending through the lug;
- and
- a chord line defined by a linear distance from the leading edge to the trailing edge;
- a mount extending from an interior surface of the body;
- and
- a pivot coupling the deployable wing to the body, the deployable wing configured to rotate about a rotational axis from a stowed position to a deployed position, the pivot comprising:
- a washer plate disposed between the lug and the mount;
- a bushing comprising:
- a collar extending through the lug bore;
- a flange extending perpendicularly from the collar such that the lug is disposed between the flange and the washer plate;
- and
- a rabbet adapted to receive the washer plate;
- wherein the rotational axis forms a first projection in the lateral plane forming a first acute angle with respect to the longitudinal plane and a second projection in the longitudinal plane forming a second acute angle with respect to the lateral plane;
- and
- wherein the chord line forms an acute angle with the lateral plane of the projectile in the stowed position.
