Failures in aircraft electrical power systems can compromise the readiness, safety, and capabilities of the war-fighter. Furthermore, if the root cause for the failure cannot be quickly identified, this can lead to increased maintenance costs and potential downtime for the aircraft. In this effort, enhanced diagnostic and prognostic algorithms will be implemented in a hardware unit to minimize suc ...

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 ...

Rechargeable batteries self discharge while in storage, and when allowed to remain at an extremely low state of charge for a long period of time, can be damaged permanently and then must be discarded. The USMC finds it far too costly and impractical to perform manual maintenance recharges every 3 to 6 months on the millions of rechargeable batteries in its inventory. In response to their requireme ...

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.

The development of Wide Bandgap Semiconductors such as GaN has enabled tremendous improvements in power amplifier performance such as operational frequency and output power. These device improvements have in turn enabled performance and capability improvements in the end applications such as EW systems and radar T/R modules. The advances in device technology have not come without their own set of ...

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. ...

ABSTRACT: Computational electromagnetics and inverse methods are the foundations of modern methods of eddy-current nondestructive evaluation (NDE). In this project, we apply these methods to the problem of characterizing, in three dimensions, damage in complex aircraft structures. As the maintenance of the structural components of aircraft moves from time-based maintenance to condition-based mai ...

In this Phase II SBIR program, Tetramer Technologies will develop new, commercially attractive, patentable, UV curable refractive index (RI) matching materials which have a significant shelf life in the uncured state. The value proposition to the customer working with fiber optic cabling will be increased reliability in refractive index matching adhesives(IMA) for fiber optic coupling and increase ...

The proposed project will focus on the development of closed loop frequency control hardware and algorithms for control of high quality factor tunable microwave filters based upon evanescent mode resonators. The developed controller will be integrated with a representative filter. As a system demonstration, the integrated filter/controller module will then be applied to a next generation frequency ...

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 ...
