A network interface chip (NIC) that implements appropriateportions of the lower 2 layers of the ANSI 709.1 protocol(LonTalk) has been successfully designed and tested on aprogrammable logic device.This NIC has been successfullyinterfaced to a NetSilicon 32 bit ARM processor runningappropriate portions of the upper layers of the 709.1 protocol. Afeasibility demonstration was conducted successfully. ...

During Phase I, Advanced Turbomachinery Solutions designed andtested a proof-of-concept, reverse rotation capable brush seal.All project objectives were met successfully. The new, hybridseal design can be retrofit into existing gas turbine designs,within the present geometric envelope, utilizing the same orimproved materials. The new seal design has improved leakage andwear characteristics over e ...

A 4-channel marine mammal detection and classification system capable of automatically detecting and classifying marine mammal vocalizations will be developed under this Phase II effort. The system will allow the operator to view marine mammal vocalizations throughout the spectrum and will include audio tools which support translation and expansion of these sounds. The Teledyne-Benthos ATM-900 b ...

Environmental degradation of aerospace turbine components is a major concern for aircraft and power generation systems, and various surface treatments are utilized to extend the lifetimes of these critical components. This Phase II project is targeted toward extending the durability of thermal barrier coatings (TBCs) on hot section turbine components. TBCs are highly susceptible to degradation b ...

CME's approach, results from Phase I and proven experience associated with high-pressure gas systems will facilitate the development of an efficient, lightweight, all-electrical, high-pressure Nitrogen Charging System (NCS), designed for field deploymenton the Marine Corps new AAAV. Custom components and COTS where available will be integrated into a final unit that optimizes the performance, size ...

One of the most important problems encountered in an electromagnetic environment is that of providing compatibility between radiating and receiving RF equipment within the environment. This problem is a type of EMI and the goal of RF system designers and analysts is to achieve EMC where no interference problems exist. We propose to develop a software tool named Electromagnetic Interference Toolki ...

Modern aircraft include numerous RF systems and associated antennas of diverse types. The designed performance of antennas is typically degraded by their installation on the airframe. Also, the presence of many RF systems in a small region creates enormous opportunity for undesired interference via antenna-to-antenna coupling. These conditions present serious challenges for engineers tasked with i ...

Spatial disorientation (SD) and the subsequent loss of situation awareness account for a significant percentage of fatal mishaps in aviation. SD typically occurs when visual references are compromised, and the pilot’s vestibular and somatosensory (tactile) sensations no longer provide accurate gravity vector information due to changing acceleration and gravitational forces. Under these condition ...

This program is intended to advance the state-of-the-art d36 shear mode projector. Phase I of this effort produced a projector which demonstrates promising bandwidth and source level, especially considering its compact size. It is also the first known d36 underwater projector in the history of piezoelectrics. To develop a robust, high power, and broad bandwidth d36 shear mode projector array and b ...

The objective in this exploratory development is to design, fabricate and test a dual-mode radome for a high speed missile application. Performance, cost and ease of manufacturing will be emphasized. Radome models will be produced to be as close toflight hardware as practical. The use of an insert to provide performance enhancements will be incorporated into the design.
