INSIDE TRACK Parvus Receives $3.3M Order for Army Kiowa Helicopter Program Parvus Corporation, a Eurotech subsidiary, has announced it received a $3.3 million follow-on order from Mercom Inc. to supply DuraCOR 810Duo tactical computer subsystems that will be integrated into U.S. Army OH-58D Kiowa military helicopters (Figure 1). Deliveries will take place within year end. The U.S. DoD recently announced that Army Contracting Command, Redstone Arsenal, AL, had awarded a firm-fixed-price contract with a maximum value of $7,278,762 to Mercom for the procurement of DuraCOR computers in support of this program. The DuraCOR 810-Duo is a rugged multicore mission processor subsystem designed for high-reliability applications requiring MIL-STD810G environmental compliance with extreme temperatures, shock/vibration and ingress. Based on a modular, open architecture COTS design with an Intel Core2 Duo CPU, solid state disk, MIL-704/1275 power supply and conduction-cooled chassis, the DuraCOR 810-Duo is an ideal computing solution for harsh mobile military and homeland security C4ISR deployments.

PICMG Ratifies MicroTCA.2 Specification for Rugged Applications PICMG has announced the adoption of the Hybrid Air/Conduction Cooled MicroTCA (MicroTCA.2) specification. The PICMG MicroTCA.2 specification addresses the needs of severe shock, vibration and thermal environments typical of many military air, land and sea as well as rugged industrial applications. The specification defines a modular open systems approach for hardened hybrid air/conduction-cooled computer systems. It was developed based on key input from military vendors such as BAE Systems, and includes well-defined test procedures for a consistent reading of vendor compliance. 8

An OH-58D Kiowa Warrior helicopter from the 1st Infantry Division takes off on a mission in 2004 from Forward Operation Base MacKenzie, Iraq. It is armed with an AGM-114 Hellfire and seven Hydra-70 rockets. MicroTCA.2 modules of all power levels benefit from the hybrid air/conduction-cooling (hybrid cooling) approach, in which conduction allows thermal sharing among modules and with the chassis. This thermal sharing effect allows additional surface area to be exposed to the airflow through the chassis to more effectively dissipate the system’s total thermal load. By taking advantage of complementary conductive heat transfer through finned clamshelled module surfaces and aluminum chassis sidewalls, as well as heat sharing between adjacent chassis slots, the MicroTCA.2 hybrid cooling solution effectively provides increased thermal margin.

AR Modular RF Device Selected for USAF C-130 Upgrade AR Modular RF has been selected as the top choice to upgrade a number of C-130 onboard aircraft communications amplifiers. The C-130 upgrades will employ the latest technologies to fulfill its primary mission to support troops, serve as convoy escorts, and continue its role as the point of defense (Figure 2). The upgrades focus on the latest versions of the airframe by stepping up the communication capabilities and extending the communication range. A pair of AR-75 “Tactical Booster Amplifiers” is installed on each airframe. This AR Modular RF amplifier is compact, lightweight, and exceeds the shock and vibration requirements even
A C-130 Hercules, equipped with the U.S. Forest Service Modular Airborne Fire Fighting System, lands at Laughline Air Force Base, Texas. when direct mounted to the airframe. In hostile environments, where dependable mission-critical communications is essential, the AR-75 outperforms all expectations. The Model AR-75HPS is a fully
