A directional ordnance for a missile. The missile contains circuitry to determine the direction of a target relative to the missile and to selectively detonate directing charges to force the blast from the warhead towards the target. The circuitry for determining the direction of the target includes two transmit antennas, each transmitting a different pseudo noise sequence, and two receive antennas; each coupled to a receiver which can determine the level of each pseudo noise sequence at each re…

An explosive logic network, including a first explosive path which is crod by second explosive paths such at a detonation propagating along the second path in either direction would cut and open a first end of the first path, and will be propagated at an opposite second end of the first path. The two paths are connected by explosive logic elements such that a detonation propagating from the first end to the second end of the first path will also be propagated in both directions along the second …

The seal bellows of a Stirling cycle device is connected between the bottom of a reciprocating piston and a cylinder wall to form a buffer space between the cycle working space and the lubricated crankcase. The piston and cylinder wall form a noncontact clearance seal between the buffer space and the working space in which an expander piston has a vented clearance seal to reduce the thermal loss due to cold gas leaking along the clearance seal.

Kinematic data is generated onboard an aircraft for describing its state of motion as it flies over a tracking range. The kinematic data is transmitted to a plurality of remote stations on the tracking range and tracking data is generated which represents the actual state vector of the flying aircraft. Also generated is pseudo tracking data, identical to the tracking data but delayed in time, for representing the motion and trajectory of a pseudo aircraft. Utilizing the pseudo tracking data an i…

A major increase in terminal explosive energy of a missile by reacting bulk aluminum, titanium, magnesium, steel, and/or organic matrix composite missile structure with oxygen enriched air which is collected as the missile flies to its target. Oxygen rich air is produced from a small amount of engine bleed or atmospheric air processed through a molecular sieve on board oxygen generating system (OBOG), and stored under pressure in the missile fuel tanks as they are emptied during flight. Explosiv…

This invention provides a fuze which includes metering means for deriving a firing signal from the frequency-time characteristic of electrical analogue signals derived from the vibrations emanating from a moving vehicle. The firing signal may be derived by integrating or differentiating the characteristic or by measuring the instantaneous frequency of the analogue signals.

The guide portion of the cylinder of a Stirling cycle device is located at least partially within and is axially coextensive with the bellows thereby providing a reduction in the height/length of the piston, cylinder and bellows assemblies. The reduction is the distance between the guide surface and the top of the piston reduces the moment arm for canting.

A munition incorporating a miniature transmitter (25) and a piezoelectric power supply (45) which converts a portion of the kinetic energy of the projectile (20), upon impact, into radio frequency energy and radiates that energy into space. The transmitter (25) can be made in suitable sizes to fit various calibers of ammunition. Different caliber ammunition can be made to radiate different frequencies. The transmitted RF energy allows the point of impact of the projectiles to be located with a h…

An explosive panel, in which detonation is limited to a predetermined area bout any point in the panel at which detonation is initiated, consisting of an array of identical interconnected explosive tile assemblies, each including an explosive tile, a peripheral explosive path, and a plurality of connecting links crossing the peripheral path at a destructive crossover. The outer end of each link is connected to the outer end of an adjacent tile assembly link, and the inner end of the link is conn…

An aerodynamic fin and stowable jet vane system preferably for rocket motor issile applications to control roll, pitch, and yaw, in either the aerodynamic or thrust flight control conditions, has a retractable and stowable aerodynamic vane integrated with a stowable thrust vector reaction steering system on a common support. The integrated aerodynamic fins and thrust vector control reduce the overall missile mainframe dimensions and are mounted on a single, space saving support.
