The primary objectives of the proposed effort are to enhance, expand, and validate a variable-fidelity transient multi-domain software toolset called ATTMO+ for predicting and analyzing the dynamic interactions at a mission-level timescale between electri

The purpose of this multi-phase program is to develop an autonomous system that is capable of aligning probes for eddy current inspections on steam condensers. The system aligns the eddy current inspection probe over the appropriate condenser tube based on a provided positional information and visually signals the operator to continue with inspection following a prior obstruction detection check. ...

This project will develop tunable notch filter for the mitigation of co-site interference and jamming sources. The novel filter technology explored in the Phase I program has displayed excellent potential to provide wide tuning capability, low out-of-band insertion losses, deep notch depths, compact form factors and low power consumption. Furthermore, by using novel MEMS tuning membranes, high fil ...

Wolf Technical Services, Inc. (Wolf) is developing a Modular Anthropomorphic Test Device (ATD) that is specifically designed for use in blast and ballistic testing. The ATD offers improved biofidelity compared to existing ATDs, with a frangible skeletal system and soft-tissue covering that simulates the human form. Sensors are provided to document loads experienced during impact events.

State-of-the-art electrical starter/generator (ES/G) systems have become increasingly complex in design and integration due to significant power-demand increase in more electric aircraft initiatives such as the Joint Strike Fighter (JSF). They must provide high performance and high efficiency with limited active cooling availability. In order to satisfy the power demands and harsher environments a ...

Recent advances in commercially available Gallium Nitride (GaN) MOSFETS offer significant advantages compared to traditional Silicon devices for circuit protection and power distribution applications including the availability of devices in advanced packaging options, lower on-state resistances, and improved performance in harsh electromagnetic environments. To demonstrate these advantages of GaN ...

Operation of turbine engines in marine environments presents a great challenge for bearings and gears composed of Pyrowear 675. The harsh environment reduces bearing life and increases unscheduled maintenance. IBC Materials is developing an industrial-scale, novel thermal process utilizing a unique atmosphere and innovative heat treat process. Using this approach, IBC will significantly improve th ...
