Power Management for the Electric Taxiing System Incorporating the More Electric Architecture

With airlines increasingly directing their attention to operating costs and environmental initiatives, the More Electric Architecture for Aircraft and Propulsion (MEAAP) is emerging as a viable solution for improved performance and ecofriendly aircraft operations. An electric taxiing system was developed that does not require the use of jet engines or the auxiliary power unit (APU) during taxiing, either from the departure gate to takeoff, or from landing to the arrival gate.

Implementing Interconnected Generation in Future Civil Aircraft

In addition to providing thrust, the engines on conventional civil jet airliners generate power for onboard systems and ancillary loads in the form of pneumatic, hydraulic, and electrical power. There is a move to begin replacing mechanically, hydraulically, and pneumatically powered aircraft systems with electrical equivalents, towards the ultimate goal of achieving the All-Electric Aircraft (AEA).

iSLC Flash Technology

Robots have been employed by the military to assist in missions where it would be, and has been, too dangerous to have a human being take on the task. These robots can detect and disable bombs. Some can be thrown into rooms where they land on their “feet”, and scan the room for counter-insurgents. Others blow up mine fields, to ensure safe travel of ground vehicles and the personnel they carry.

OpenVPX(R) 40G Ethernet + InfiniBand(R) Switch Card

Curtiss-Wright Controls Defense Solutions (Ashburn, VA), a business group of Curtiss-Wright Controls, has introduced the newest member of its Fabric40(TM) family of extremely high-speed 40 Gbps OpenVPX™modules. The new VPX6-6802 Fabric40 Switch is the first rugged, high performance 6U OpenVPX (VITA 65) switch card to provide support for 10/20/40 Gigabit Ethernet (GbE) and SDR/DDR/QDR/FDR-10 InfiniBand®(IB) connectivity to OpenVPX™ systems. Systems built using the VPX6-6802 and complementary Curtiss-Wright Fabric40 system elements will deliver over 2x the performance of previous generation SRIO Gen-2-based systems and 4x the performance of 10 GbE-based systems. The fully rugged VPX6-6802 is available in air-, conduction-, and air flow-through (AFT)-cooled configurations. Designed for use with today’s highest speed switched fabrics, the board provides a combined Data Plane and Control Plane high-performance switch for 6U VPX systems.

Power MOSFETs

Mouser Electronics, Inc. (Mansfield, TX) now stocks International Rectifier’s (IR) family of AEC-Q101 Automotive qualified 40V N-channel MOSFETs, featuring IR’s proven Gen12.7 trench technology with ultra-low Rds(on). International Rectifier's Automotive COOLiRFET™ Power MOSFETs target rugged automotive applications. These HEXFET® Power MOSFETs achieve very low on-resistance, resulting in highly efficient switching of high current signals with very little power loss. Additional features include a high 175°C junction temperature, fast switching speeds for better power efficiency, and a high repetitive avalanche rating for harsh signal environments. These new devices offer low conduction losses and robust avalanche performance to deliver higher efficiency, power density and reliability. Applications using these new IR COOLiRFET™ devices from Mouser Electronics can run significantly cooler than comparable MOSFETs.

MicroTCA Ecosystem

VadaTech (Henderson, NV) has released a complete ecosystem of boards and chassis in the MicroTCA architecture that is conduction-cooled. Designed for rugged applications, the products include air transport racks (ATR), MicroTCA carrier hubs (MCH), power modules, and advanced mezzanine cards. Compliant to MicroTCA.3 (Hardened Conduction-Cooled MicroTCA) specification, the boards and chassis come in various sizes and formats.

The MCH, which acts as a shelf controller, features a 400 MHz RISC CPU for high performance and low latency. The power modules provide true hot- swappability in a dual 10-36V input and outputs of up to 800W. They also have dual Intelligent Platform Management Interface (IPMI) and two banks of 256K flash for redundancy. Several of VadaTech’s advanced mezzanine cards (AMCs) are in the conduction-cooled format. The company is also able to modify standard AMCs to ruggedized versions with wedge locks.
