GriggTech, Inc.
The two LRUs shown above were provided by GriggTech (formerly Cybernetic Systems-CSI) to FN and FZ, and were used in conjunction with the FN PC-16 aboard the McDonnell Douglas Helicopter Company's (now Boeing) MD530MG Defender demonstrator helicopter to control various FN gun pods and FZ rocket launchers. The GRCP-19 controlled the RCU-70R rocket functions via an RS-422 half duplex serial data bus.
GriggTech was given a letter of commendation by MDHC congratulating GriggTech on it's AMS flawless performance throughout their world tour during 1984.
Shown above is the cockpit installation of the armament control panel (GRCP-19) in the center console between the two crew members.
This photo shows the installation of the FN PC-16 gun pod power control unit and the GriggTech RCU-70R remote-mount rocket control unit in the cabin of the MD530MG Defender helicopter.
The PC-16 is the large yellow anodized box toward the top of the photo, and the RCU-70R is mounted upside down just below the PC-16.
To illustrate the large size of the FN PC-16 unit, the RCU-70R dimensions are 6.5Lx5.0Wx3.25H.The PC-16 is typical of the size of AMS available today from other AMS providers.
This photo of the MDHC MD530MG Defender demonstrator helicopter at Camp Pendleton, CA shows the array of weapons controlled by the GRCP19/RCU-70R/PC-16 combination. The photo was taken just after qualification testing was completed.
This above photo was taken at the 1985 Paris Air Show at the Bristol Aerospace booth. Bristol Aerospace invited GriggTech (then Cybernetic Systems, Inc.) to share their booth.
Shown are the RCU-70P (Single-Box, Panel-Mounted 70mm Rocket Control Unit) and the LSU-70 (Launcher Simulator Unit-Special Test Equipment) that were provided under contract to FZ.
The RCU-70P controlled FZ 7-, 12- and 19-tube rocket launchers, and included Hydra-70 fuze setters.
