Abstract: An apparatus for repairing a pair of non-conforming bushings on the M89E1 Declutching Ammo feeder for the M197 machine gun. The apparatus includes a central body and a pair of large drill plates which allows a user to drill out the non-conforming bushings from the ammo feeder. The user then press fits replacement bushings into the ammo feeder. The apparatus also includes a pair of small drill plates which allows the user to drills pin mounting holes into the replacement bushings.

Abstract: A TM microstrip antenna designed to transmit telemetry data for use by a nine inch diameter projectile. The microstrip antenna is configured to wrap around the projectile's body without interfering with the aerodynamic design of the projectile. The TM microstrip antenna operates at 2.25 GHz with a bandwidth of ±10 MHz. Eight microstrip antenna elements equally spaced around the projectile provide for linear polarization and a quasi-omni directional radiation pattern.

Abstract: A spiral antenna having a pair of antenna arms mounted on a dielectric substrate. A balun is included to connect the antenna which has an impedance of 100 ohms to a 50 ohm cable. Unique features of the spiral antenna design provide for size reduction at a given lowest required frequency of operation. The spiral antenna has dielectric material layers positioned on both side of the antenna's metal arms. In addition, the antenna input impedance is reduced from the normal 100 ohm input impedance to approximately 50 ohms due the dielectric material.

Abstract: A short ridge waveguide load is described which absorbs and cancels non-radiated electromagnetic energy in continuous slot or discrete slotted antennas. The load achieves a small physical size by using a resonant structure which includes an absorbing ferrite front section positioned within the interior of the waveguide antenna below the slot and a back section of ferrite material also positioned in the interior of the waveguide antenna. This allows for energy to be radiated from the slot while absorbing and canceling the non-radiated energy using a relatively small size load. In a rectangular ridge waveguide configuration, the front section consists of a pair of posts having a trapezoidal, rectangular or triangular shape.

Abstract: A method using a Non-Volatile Memory circuit which operates as an interface between a key loader and an encryption device in a missile's telemetry system. The method includes a step for storing a crypto key and an associated check word and a backup crypto key and check word in the EEPROM of a microcontroller, and a step for indicating the status of a load of the crypto key in the microcontroller as well as a step for indicating the status of an erase of the crypto key from the microcontroller. The method also includes a step for turning off the missile's transmitter when a key load occurs to prevents transmission of the crypto key and its corresponding check word. The method further includes a step for erasing the crypto key and its associated check word from an EEPROM within the microcontroller upon a missile launch.

Abstract: A Non-Volatile Memory circuit operating as an interface between a key loader and an encryption device. The Non-Volatile Memory circuit includes a microcontroller which stores a crypto key and checkword and a backup crypto key and checkword. The microcontroller is connected to the telemeter transmitter for a missile allowing the micrcontroller to turn off the transmitter during a key load which prevents transmission of the crypto key and checkword. When the microcontroller completes a load of the crypto key to the encryption device and upon a launch of the missile, software within the microcontroller erases the crypto key and checkword from an internal EEPROM. This prevents an enemy force from retrieving the crypto key and its corresponding checkword from the missile after launch.
