Abstract

A set back weight is moved by inertial force from a first position to a second position during acceleration of a missile. The set back weight is biased toward its first position to preclude its movement to its second position until the missile undergoes the rate of acceleration which is normally associated with a successful launch of the missile. Upon reaching the second position the weight becomes connected to a piston disposed in a fluid containing reservoir so that when the missile undergoes a reduction in its rate of acceleration and the set back weight moves toward its first position that movement is transmitted to the piston to express fluid from the reservoir. Fluid from the reservoir flows into a working cylinder to move an arming piston therein. Movement of the arming piston is slowed to delay arming of the missile by a flow restricting orifice in the path of fluid flow from the reservoir to the working cylinder.
