12A POL DC-DC Converters

TDK Corporation (National City, CA) has introduced the 12 Ampere TDKLambda iCH series of POL (Point of Load) non-isolated DCDC converters. Accepting a wide range input of 4.5 to 14 VDC, the series can operate from either a 5 VDC or 12 VDC bus. The iCH series can provide output voltages from 0.7 to 8.5V, with efficiencies of up to 97%. A low internal power loss allows the iCH to deliver 12A output current, without forced air cooling, in ambient temperatures in excess of 70 °C.

AdvancedTCA Chassis

Pixus Technologies (Waterloo, Ontario, Canada) now offers a 15U AdvancedTCA (ATCA) chassis that exceeds 400W/slot cooling capability and meets stringent NEBS requirements. The Pixus chassis leverages the original Kaparel design that used patented Ri- Cool II blowers for 275W/slot of cooling. Today’s 15U unit provides more air evacuation using the next generation of reverse impellar hot-plug cartridges. The new RiCool III blowers feature 185 CFM of airflow per fan with 71mm H20 of static pressure.

Next Generation FPGAs for Electronic Warfare Systems

Designers of virtually all electronic warfare system applications exploit CPUs and FPGAs, each offering unique strengths and advantages for handling a wide range of tasks. This diversity arises from fundamental differences in the devices. FPGAs consist of hardware logic, registers, memories, adders, multipliers and interfaces connected together by the user to perform a specific function. CPUs consist of ALUs, instruction execution engines, cache memory, dedicated I/O and memory ports all connected in a fixed architecture, whose resources are driven by program execution.

Managing the Impact of Nanomaterials in Aerospace Manufacturing

As the aerospace industry continues to make improvements to safety, comfort and affordability of aircraft, nanomaterials are making their way into more elements of aircraft structure, electronics, glass, textiles and other components. While these materials provide tangible advantages in terms of weight, strength, speed and comfort, their effect on the humans that come into contact with them is still being studied and debated.

Turbine Flow Meters: Technology-of-Choice for Measuring Critical Fluid Flow Applications

The aerospace industry has some of the most difficult operating conditions imaginable. Sensors of all kinds used in this industry must stand up to the environment and be able to perform under harsh conditions, fit in extremely tight spaces, and have electronics that can compensate for variable conditions in order to provide precise, repeatable results.

Designing a Power Generation System for a More-Electric Aircraft

It is theorized that systems and equipment for an All Electric Aircraft (AEA) will be developed 20 years hence as a More-Electric Aircraft (MEA) with no bleed system, which is a concept typified by the Boeing 787, and electric powered propulsion (including electric distributed thrust or electric hybrids by gas turbine power generation), which is expected to be realized after the 2040s. In this trend, a More-Electric Engine (MEE) plays the roles shown in Table 1.

Developing an Auto-Synchronized Multi-Avionics Protocol Data Bus Acquisition System

A modern aircraft includes multiple intelligent subsystems that aid in communication, navigation, and surveillance. These subsystems, called line replaceable units (LRUs), are modular and easy to replace in the field. Typically, independent teams design and develop LRUs. It is important to test the LRUs with a test rig on the ground before integrating them on the aircraft. A ground-based LRU integration rig (LRUIR) facility uses state-of-the-art hardware and software in a distributed architecture to help completely integrate the process of verifying the functionality of the avionics subsystems. An LRUIR provides a platform to test the LRUs in an integrated environment on the ground.
