SMT Top Actuated Switch

C&K Components (Newton, MA) has developed the new PTS 530 Series ultra-low- profile top actuated SMT switch. Utilizing C&K’s unique symbol line identification system, design engineers can quickly and easily identify actuation force ratings. The marking system defines the model number and actuation force on the switch itself, which eliminates the need for designers to rely on confusing schematics. The PTS 530 Series SMT switch is only 4.5mm x 4.5mm with a 0.55mm thickness (0.65 mm for high force versions) and features a lifespan of up to 1,000,000 operations. The momentary action, top actuated SMT switch features a gullwing or J-type terminal and can be soldered via infrared reflow in accordance with the IEC61760-1 standard. The PTS 530 Series switches are available in six different varieties, dependent on actuation force. The PTS 530 Series SMT switch has a maximum voltage of 12VDC. The operating temperature range is -40°C to +85°C.

10-bit DAC (25 GS/s)

Curtiss-Wright Controls Defense Solutions (CWCDS) (Ashburn, VA) announced that it will bring the unmatched data conversion performance of Tektronix Component Solutions’ newly introduced TDAC-25, the industry’s first 10-bit 25 GS/s digital-to-analog converter (DAC) ASIC to the defense, aerospace, telecom, commercial, and medical markets on its new CHAMP-WB family of rugged OpenVPX(TM) modules. The TDAC-25, which delivers up to -60 dBc of dynamic range and enables direct-generation of wideband signals. Curtiss-Wright will first deliver the TDAC-25 on the recently announced CHAMP-WB-DRFM card set featuring the Tektronix 12.5 GS ADC/DAC-based TADF-4300 module. The TADF-4300 was jointly developed by Curtiss-Wright and Tektronix for use with the CHAMP-WB Xilinx(R) Virtex(R)-7 based 6U VPX card. The first announced member of the CHAMP-WB family, the CHAMP-WB-DRFM card set deploys the TDAC-25 as part of an ADC/DAC combination with maximum module speed rated at 12.5 GS/s.

Software Design for CFD Rotary-Wing Aeromechanics Modeling

Helicopter flight involves many multidisciplinary physics problems that are difficult to predict with today’s engineering modeling and simulation tools. Rotor aerodynamic systems involve complex interactions among the rotor blades, rotor wakes, and fuselage, and they create challenges such as simultaneous modeling of rotating and nonrotating components; retreating-blade, low-speed dynamic stall; advancing-blade transonic flow; rotor “trim” requirements to balance aerodynamic and dynamic forces for particular control settings; and strong coupling between rotor-blade aerodynamics and rotor blade dynamics (both rigid and elastic blade motion).

Crumple Zone Software Absorbs Attack Effects Before System Failures

A higher level of structural and operational endurance and ruggedness can be achieved in software systems by strategically introducing crumple zones (CZs) in the system architecture. Analogous to the crumple zone in an automobile, a CZ stands before critical components and “absorbs” the effects of attacks by localizing or eliminating the damage they can cause and leaving the critical components intact and unaffected. The concept of software CZs is broadly applicable; this work focuses on CZs for SOA.

General Runtime/Architecture for Many-core Parallel Systems (GRAMPS)

The era of obtaining increased performance via faster single cores and optimized single-thread programs is over. Instead, a major factor in new processors’ performance comes from parallelism: increasing numbers of cores per processor and threads per core. In both research and industry, runtime systems, domain-specific languages, and more generally, parallel programming models, have become the tools to realize this performance and contain this complexity.

Weapon Center of Mass Calculator

The Weapon Center of Mass (COM) software allows researchers to easily determine mass properties of a weapon system. The tool presents a photograph of the weapon and allows the user to place weight anywhere on the weapon by clicking on the screen. After the weight is placed, the software returns the mass properties of the weapon, including the effects of the added weight. It is based on fundamental equations found in physics and biomechanics, and can determine the effects of as many as four added weights. The added weight can be accoutrements (such as new sights), additional weapons (such as a grenade launcher), or any other object that is mounted to the weapon.

Intelligence Analysis System

Air Force intelligence analysts must assess an adversary’s capability to achieve their objectives, including their offensive and defensive systems, state of readiness, training, and conditions such as weather. To effectively assess these capabilities, analysts must integrate a tremendous amount of data from a number of sources. An automated decision support system can help analysts manage and process the information.

One-Shot Sniper System

The Defense Advanced Research Projects Agency (DARPA) has awarded Cubic Defense Applications, the defense systems business of Cubic Corporation, a $6 million contract to develop the next generation (XG) of the One Shot crosswind and range measurement system. The technology will provide ballistic aim point offsets in the shooter’s riflescope sight. The fielddeployable system is compact enough to have the option of mounting on the rifle or the spotter-scope, enabling military snipers to rapidly hit their targets at maximum effective ranges and under crosswind conditions.

Light Combat Tactical All-Terrain Vehicle

Oshkosh Defense, a division of Oshkosh Corporation, has unveiled its Light Combat Tactical All-Terrain Vehicle (L-ATV) utility variant for the Joint Light Tactical Vehicle (JLTV) program. The L-ATV utility variant fulfills the JLTV requirement for a two-seat cargo vehicle, while the L-ATV base variant meets the requirement for a 4-seat multipurpose vehicle. Both Oshkosh L-ATV variants leverage a common crew protection system, advanced automotive systems, and the patented Oshkosh TAK-4i™ intelligent independent suspension system to deliver a superior level of protection and off-road performance in a light vehicle.
