12 Jan 06. A Raytheon Company-led team has successfully demonstrated the rocket motor for its Advanced Precision Kill Weapon System II 2.75-inch laser guided weapon system. The five static test firings at the Aerojet test facility in Orange, Calif., in September 2005, proved the design maturity of the innovative tailfin and nozzle assembly, the operational reliability and the successful integration of the tail fin assembly with the existing MK66 rocket motor. A major benefit of the tail fin modification is the reduced ballistic dispersion of both guided and unguided rockets, which was proven by six berm tests in October, 2005, at Energetic Materials Research and Testing Center, Socorro, N.M., and 13 ballistic test firings in October at Yuma Proving Ground, Ariz. All demonstrated the predicted performance improvements.
17 Jan 06. Building on the company’s extensive experience in data acquisition and signal processing in military sonar systems, ICS – part of Radstone Embedded Computing – today announced the unique ICS-8145 16-channel data acquisition card. The ICS-8145 is the only data acquisition card currently available that combines rear I/O with onboard signal conditioning circuitry in a rugged, single slot package. Designed for harsh environment, confined space high frequency sonar, wet end of towed arrays, torpedoes, autonomous underwater vehicle (AUV) and unmanned underwater vehicle (UUV) applications, the ICS-8145 is a complete, self-contained solution that eliminates the need for auxiliary equipment that characterizes other offerings.
16 Jan 06. Curtiss-Wright Controls Embedded Computing has introduced the SCP/DCP-124, a new high performance ruggedized 3U CompactPCI (cPCI) single board computer. The SCP/DCP-124, available in both conduction cooled and air-cooled versions, delivering a rich complement of I/O in a compact 3U form factor. Powered by Freescale’s 7447A/7448 PowerPC processor, the card simplifies the design of space and weight constrained COTS systems for military and aerospace applications. The SCP/DCP-124 is the latest addition to Curtiss-Wright’s extensive CompactCore cPCI product family.
“3U CompactPCI is growing in popularity as an SBC platform for space constrained military platforms,” said Lynn Patterson, vice president and general manager of Modular Solutions, Curtiss-Wright Controls Embedded Computing. “The conduction cooled, ruggedized SCP/DCP-124 delivers the highest level of computer power available on a 3U cPCI, giving system integrators greater freedom to deploy high performance system in harsh environments.”
The board’s 7448 PowerPC is supported with 1 MB of internal ECC L2 Cache memory running at core processor speed, and up to 512 Mbytes of DDR1 SDRAM with ECC. The SCP/DCP-124 can function either as a system slot board (controlling up to 6 cPCI slots), or as a peripheral board, with auto-sensing provided to determine the mode of operation. Its cPCI bus operates at 33MHz or 66MHz, supporting both 3.3V and 5V signaling. System expansion is via the SCP/DCP-124’s on-board 64-bit, 100 MHz PCI-X capable PMC site.
TheSCP/DCP-124 eases system upgrades via pin-out modes fully compatible with Curtiss-Wright’s earlier SCP/DCP-122 3U cPCI SBC board. To ease system integration and development, a rear transition module and/or cable set are also available. A debug monitor (GPM) and Built-in Test (BIT) with 95% fault coverage are both provided in firmware.
