Today’s Warfighter often carries an inordinate load that can lead to injuries and encumbered performance. Equipment is distributed among squad members with little, if any regard for differences in strength and anthropometry. Consequently, the current focus on human-centric design requires a modeling and simulation tool that can reduce the load Warfighters carry and can help distribute equipmen ...

Acoustic liners are presently used for attenuating combustion and turbine noise radiated from jet engines. Current acoustic liners are passive by nature. This is a drawback because they are only able to absorb acoustic energy over a limited bandwidth. A possible solution to this drawback is the development of an active acoustic liner. The main advantage of this concept is the ability to tune the ...

A class of high amplitude and high bandwidth actuators called localized arc filament plasma actuators (LAFPAs) have recently been developed at OSU and used for control of high-speed and high Reynolds number jets. The control included successful noise mitigation in a Mach 0.9 jet and mixing enhancement (and very preliminary results for noise mitigation) in a Mach 1.3 ideally expanded jet. The contr ...

The proposed development will result in a compact, efficient, broadband transducer module including amplifier and wet-end transducer. To facilitate multiple mission requirements, the transducer performance goals are a broad bandwidth (7-30 kHz), compact size on the order of 1/2 wavelength at the center frequency, at least 30 watts output power, and high efficiency. The resulting technology from ...

The Phase I effort successfully developed an integrated magnetostrictive transducer/amplifier module concept to meet these performance goals: broad bandwidth (7-30 kHz), compact size (approximately ½ wavelength at the center frequency), at least 30 Watts output power, and high efficiency. Conceptual designs of the transducer, amplifier, and the integrated transducer module developed during Phas ...

The objective of the proposed Phase-I research effort is to assess the feasibility of performing high-speed (1-5 kHz) particle-image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) for understanding combustion stability and related phenomena in gas-turbine augmentors. Initial demonstration measurements will be performed in cold and heated air flows using PIV and acetone/biacetyl PL ...

The objective of this Phase-II effort is to build and deliver a high-speed laser system for performing particle-image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) of OH at rates of 5 to 10 kHz in augmentor test facilities. This state-of-the-art laser system will allow velocity and 2-D flame radical measurements for understanding the complex spatio-temporal development of instab ...

Current ASW missions require low frequency off-board sound sources that can operate monostatically or bistatically. Since these sources may or may not be recoverable, and may require a substantial number to cover the designated operating areas, the low frequency source transducers also need to be low cost. The team of Etrema Products and Applied Research Laboratory at The Pennsylvania State Univ ...

The objective of this study is to demonstrate the efficacy and broad applicability of the human immune-modulating alphaGal Adjuvant Technology for antiviral vaccine development. We will use viral vaccine candidates for the select Category A viral pathogens Zaire ebolavirus (ZEBOV, filovirus), Rift Valley fever virus (RVFV, bunyavirus), and Lassa virus (LV, arenavirus), to evaluate the adjuvant pot ...

We propose to use physiological sensors to measure the quality of a trainee's interaction with a virtual environment (VE) as a function of VE fidelity to enable design improvements in VEs and to enhance training effectiveness through feedback of physiological-based performance information. Currently, VE design is guided by subjective design models that involve multiple design iterations and focus ...
