Patent number: 8042471Abstract: A safe and arm (S&A) device is disclosed. The device utilizes a no-fire separation distance and a mechanical configuration of primary explosive/booster explosive and secondary explosive to establish a safe mode. While in safe mode, the device would allow no more than 1 in 1 million detonation transfers to occur from primary to secondary. In armed mode, the no-fire separation distance is taken away, allowing reliable detonation transfer. Two arming environments, which occur after launch and safe separation, are used to move the S&A device to armed mode. The first environment is the release event of the projectiles from their packed state in a dispenser. The second environment is a target sense mechanism. If either arming environment returns to its original state, the mechanism returns to safe mode. The S&A device will not allow inadvertent packing into the dispenser of explosive devices in the armed state.Type: GrantFiled: February 28, 2005Date of Patent: October 25, 2011Assignee: Lockheed Martin CorporationInventors: Matthew A. Michel, Joseph R. Mayersak, Lance Benedict

Patent number: 7814696Abstract: A projectile system includes an enclosure, first and second propellants, and first and second projectiles. The first and second propellants are disposed within the enclosure. The first projectile is disposed within the enclosure between the first propellant and a first end of the enclosure, and is operable to exit the enclosure via the first end in response to detonation of the first charge. The second projectile is disposed within the enclosure between the second propellant and a second end of the enclosure, and is operable to exit the enclosure via the second end in response to the detonation of the second propellant.Type: GrantFiled: October 31, 2005Date of Patent: October 19, 2010Assignee: Lockheed Martin CorporationInventors: John Rapp, Joseph R. Mayersak, Mark Jones, Michael E. Feeley, Robert J. Howard, Robert J. Varley, Stephen Melicher, Howard Taylor, Jyun-Horng Fu, Richard A. Udicious

Publication number: 20040231552Abstract: A method to increase the penetration of kinetic energy penetrating weapons designed to engage hardened and hardened deeply buried targets. The concept utilizes a projecting nose pin on the front of the penetrator to establish a terradynamic cavity similar to hydrodynamic cavities generated when certain projectiles penetrate water at velocities sufficient to penetrate in a supercavitation mode. The creation of a terradynamic cavity in which only the nose pin is in contact with the material being penetrated significantly reduces the drag of the penetrator enabling it to penetrate deeper into various media than other more conventional designs. The invention uses two modes of penetration. A guided mode is employed where the penetrator, with its projecting nose pin, normally would be unstable and is maintained stable in a straight-line trajectory utilizing an inverse, angle-angle rate guidance law and jet reaction control system.Type: ApplicationFiled: May 23, 2003Publication date: November 25, 2004Inventor: Joseph R.

Patent number: 6628231Abstract: A method is described which enables the location of a radio frequency emitting target in absolute or relative GPS coordinates from a single airborne platform within a few seconds. The method uses a signal processing technique which emulates an antenna moving at very high velocities to induce a Virtual Doppler shift on signals incident upon a linear antenna array. The Virtual Doppler shift is directly proportional to the signal direction of arrival as measured by its direction cosine. The method is shown to prevent single and multiple GPS jammers from being able to jam conventional GPS signals. Also disclosed is a means and method for developing virtual Doppler shifted signals to determine the angle-angle bearing of emitting targets to high resolution. This in turn, allows the position of the emitter to be determined in a GPS reference frame to be located to a high degree of accuracy from a single platform in extremely short times.Type: GrantFiled: October 15, 2001Date of Patent: September 30, 2003Assignee: Lockheed Martin Corp.Inventor: Joseph R.
