Compact accelerometer

Designed to fit in limited space, the LSM Accelerometer from Jewell Instruments measures about 1 in³. Its wide input range and bandwidth features meet the needs of a variety of aerospace applications: satellite motion sensing, radar leveling, fire control, altitude heading and reference systems, missile orientation, and autopilot. The accelerometer has an input range of ±0.5 to ±20 g and bandwidths (-3db) from 70 to 160 Hz. It provides a full range output of ±5 V dc and has an operating temperature range of -55 to +95°C.

Liquid-molding technology

The directed resign injection and venting (DRIV) technology from North Coast Tool & Mold enables aerospace and other high-performance composite manufacturers to fabricate parts of a size and complexity previously considered unobtainable with the liquid molding process. Traditional techniques rely on uncontrolled flooding, typically employing single-point, edge-of-the-part venting and injection, which results in dry fabric. Strategically positioning DRIV inserts in the mold during manufacturing allows air trapped in the mold and fabric to be evacuated, ensuring total wet-out without shifting fabric. As a result, the resin can be infused in targeted locations and in controlled sequences, using lower injection pressure. The process can be manually controlled or used in conjunction with computerized injection and venting.

Fiber-optic tool

Based on new fiber-optic technology, ProVision from Chicago Miniature Lamp is helping aviation technicians see into crevices and other spots that the naked eye cannot reach to detect worn parts without major disassembly. Able to fit into holes with diameters as small as 0.5 in., it can spot hydraulic leaks, look into fuel cells, and view long areas of electrical wiring that are generally hard to reach. The inspection tool is made of high-impact ABS and features an 18-in. flexible, water-tight sealed shaft. The high-resolution lens provides a clear image of objects as close as 0.75 in. from the lens to as far as 1 ft or more. It also provides a wide 40° field of view.

Fluid-handling pump

Micropump, Inc.'s Integral Series electromagnetic drive pump combines a pump head, brushless DC motor, and electronic controller into a single, leak-free pumping unit. It is available with a variety of high-quality, precision gear and centrifugal pumps. Construction materials include 316 stainless steel, Ryton (PPS), PEEK, Teflon (PTFE), and graphite, providing maximum chemical compatibility and durability. The Integral Series improves upon conventional magnetic couplings by driving the pump electromagnetically, with no moving parts in the motor. Featuring low RFI and EMI emissions, the compact design includes an electronic controller that can be operated manually or with a 0-5 V dc or 4-20 mA remote-control signal, while the patented drive system provides good reliability and long life.
