Abstract
A device, particularly a missile, includes a body having an appendage, e.g., a wing, normally folded in an inoperative position and to be unfolded to an operative position when the body is accelerated in the direction of the longitudinal axis of the body. The appendage is pivotally mounted about a first pivot axis extending perpendicularly to the longitudinal axis of the body, and also about a second pivot axis extending parallel to the longitudinal axis of the body. The center of gravity of the appendage is outwardly of the first pivot axis in the folded condition of the appendage such that the acceleration of the body produces a moment pivotting the appendage about the first pivot axis.
Claims17
A device including a body having an appendage normally folded in an inoperative position on the body and to be unfolded to an operative position when the body is accelerated in the direction of the longitudinal axis of the body;
- said device including:
- a socket member fixed to said body so as to project outwardly of its outer surface;
- a hinge member pivotally mounted at one end to said socket member about a first pivot axis extending outwardly of the outer surface of said body and perpendicular to the longitudinal axis of said body;
- the opposite end of said hinge member pivotally mounting said appendage about a second pivot axis extending further outwardly of the outer surface of said body and parallel to the longitudinal axis of said body;
- said socket member including a contact surface outwardly of the outer surface of said body engageable by said appendage in its normal folded position to locate the center of gravity of the appendage outwardly of the first pivot axis and inwardly of said second pivot axis, such that the acceleration of the body produces a moment first pivotting the appendage about said first pivot axis to move the center of gravity of the appendage outwardly of said second pivot axis, and then to move the appendage about both said first and second pivot axes to the operative position of the appendage.
A missile including a wing normally folded in an inoperative position on the missile and to be unfolded to an operative position when the missile is accelerated in the direction of the longitudinal axis of the missile;
- a socket member fixed to said missile so as to project outwardly of its outer surface;
- a hinge member pivotally mounted at one end to said socket member about a first pivot axis extending outwardly of the outer surface of said missile and perpendicular to the longitudinal axis of said missile;
- the opposite end of said hinge member pivotally mounting said wing about a second pivot axis extending further outwardly of the outer surface of said missile and parallel to the longitudinal axis of said missile;
- said socket member including a contact surface outwardly of the outer surface of the missile engageable by said wing in its normal folded position to locate the center of gravity of the wing outwardly of the first pivot axis and inwardly of said second pivot axis, such that the acceleration of the missile produces a moment first pivotting the wing about said first pivot axis to move the center of gravity of the wing outwardly of said second pivot axis, and then to move the wing about both said first and second pivot axes to the operative position of the wing.
