Abstract: A trajectory (range) control device which is designed to fit behind the f of a fin stabilized ballistic projectile for correcting range error. The trajectory (range) control device is a self-contained, add-on module, which will screw into the forward portion of the projectile. The fuze will then screw into the trajectory (range) control module, which has a small through hole that will coincide with the center of the fuze and the center of the projectile. This through hole is intended to provide a channel in which the fuze can detonate the intended booster charge which will in turn ignite the high explosive payload or function the payload of the fin stabilized ballistic projectile. The trajectory control device will not make changes to the existing projectile or fuze. During the course correction phase, eight spring loaded flare tabs will deploy from the device. The flare tabs create a blunt cross-sectional area in front of the projectile, thus creating more drag and effectively slowing the projectile.

Abstract: An explosive primer designed for use with a fuse cord and an initiating device. The primer consists of a container, which holds the explosive, and a cap received on the open end of the container. The container has two lateral opposing cord tunnels which run the length of the container. The cord tunnels protect the fuse cord on the inside of the primer. The cap has two apertures which align with cord tunnels in the container. The cap has capwell for receiving the detonator. The capwell is pierceable so that a detonator can be inserted through the capwell and embedded directly in the explosive composition inside the container. In addition, the primer contains grooves in the bottom of the container and in the cap. The grooves communicate with the apertures and the recess in the cap and the cord tunnels to create a continuous conduit so that a fuse cord can be threaded therethrough to secure the cord to the primer and selectively position the primer in a borehole at the blast site.

Abstract: A jugline fishing float visually indicates to a fisher the location of the float and when a fish has been caught, and is especially suitable for nighttime fishing. The jugline fishing float has a housing with an upper and lower container removably connected to a divider. The divider supports a stage having a circuit board mounted to a platform thereon. A mechanical actuation system is mounted to the underside of the stage. The mechanical actuation system has a contact bar which pivots about a pivot pin. The contact bar is biased against a position indicator contact by a spring attached at one end of the contact bar. A battery supplies energy to actuate a white position indicator lamp in response to the position indicator contact electrically communicating with the contact bar. The indicator lamp signals the position of the jugline fishing float to the fisher.

Abstract: A method and apparatus for determining whether a warhead in flight and forming a part of a rocket, missile, or the like, is in a state which permits arming of the warhead. The arming of the warhead depends upon the conditions of the warhead's movement and the elapsed time from its launching. A specific time slot which begins at a predetermined time after the launching of the warhead and terminates at a predetermined time thereafter is demarcated. The velocity of the warhead is measured following its launch and at least during the specific time slot. The warhead will be armed only in the event that the measured velocity of the warhead has reached at least a predetermined value within the specific time slot.

Abstract: Time delay apparatus for providing a firing action at the end of a predetermined time-delay period. It is used with a source of fluid under pressure, and defines a fluid-receiving chamber for accumulating the fluid when released from the source. A flow controller is connected between the source and the fluid-receiving chamber for providing fluid communication between the source and the fluid-receiving chamber. A triggering assembly initiates flow of fluid from the source through the flow controller and into the fluid-receiving chamber. A piston-form firing pin in the fluid-receiving chamber is actuated by shear pin release for movement to an actuating position for desired firing action when a predetermined pressure has accumulated in the fluid-receiving chamber at the end of the predetermined time-delay period.

Abstract: An infrared suppressor system for a gas turbine engine is provided for suppressing infrared radiation associated with the hot metal parts of the engine and with the hot exhaust gases exhausted from the engine. The system features a unique arrangement of multiple baffles that are connected together as a single baffle module. The baffle arrangement permits mixing of hot and cool gas flows while eliminating line-of-sight infrared radiation in an axially compact suppressor. The baffles are additionally linked together into a single insertable baffle module that permits removal of the baffle module when infrared suppression is unnecessary.

Abstract: A detonator (10) is equipped with an input lead (29) having multiple signal transmission lines (30, 31) which provide redundant initiation signals to the target charge (14) of a detonator (10, 10') thereby increasing the reliability of initiation. The multiple signal transmission lines (30, 31) may be made of shock tube and can be part of a long or short input lead (29, 129) and may be initiated by any suitable means, for example by being disposed in signal transmission relation to a detonating cord (60, 62) to improve the reliability with which a signal is transferred from the detonating cord (60, 62) to the detonator (10, 10').

Abstract: A projectile includes a mechanism which allows the fin position to be reved after the projectile leaves the launch tube thus allowing the fins to have reversed leading edges, which avoids the costly weight of the one-piece design in the prior art, which is a parasitic weight that will result in a lower velocity, and consequently lower kinetic energy, from the same propellant charge. This mechanism also avoids having extra pieces falling from the muzzle and near the firing team or troops near the gun, and has the advantage of a simple, low-weight deployment mechanism which results in the least aerodynamic resistance after full deployment. The mechanism has at least one small winglet on each reversible fin which generates an aerodynamic lifting force to provide reversal of the fin after the projectile leaves the launch tube. These winglets are positioned and designed to cause the least increase in aerodynamic drag.

Abstract: A projectile to be, fired from a non-rifled tube includes an elongated foody and a stabilizer secured to the tail end of the forebody for enhancing the projectile flight stability and for imparting spin to the projectile. The stabilizer includes a threaded member that extends integrally into a forward section, a peripheral channel and a grooved aft section. The forward section has a generally smooth cylindrical shape. The peripheral channel extends along the entire peripheral contour of the stabilizer and has a generally semi-circular cross-section, for generating an expansion wave and for directing air flow toward the grooved aft section. The grooved aft section is cylindrically shaped relative to a longitudinal axis, and has a predetermined number of identical, equally spaced, circumferentially positioned grooves which traverse the entire axial length of the aft section, and which are angled relative to the longitudinal axis. Each angled groove is defined by two substantially parallel side walls.

Abstract: A method and system for limiting missile guidance correction within the physical control capabilities of the missile, while fully utilizing missile maneuver and control capabilities. The method and system of the present invention are applied through missile guidance control electronics. First, a dynamic rate limit is calculated to prevent aerodynamic trim limit overshoot, which is directly related to body attitude rate. Second, a dynamic angle of attack limit is calculated to control aerodynamic trim limit based on thrust deflection and/or aerodynamic control surface deflection. Third, a dynamic angular acceleration limit is calculated to balance control moments produced by mechanisms such as thrust deflection and/or aerodynamic control surface deflection with vehicle moments of inertia.
