Award List:

SUBMARINE MAST WAKE REDUCTION

Award Year / Program / Phase: 1988 / SBIR / Phase I
Agency / Branch: DOD / NAVY
Principal Investigator: Raymond j grady
Award Amount: $50,000.00
Abstract:
The objective of the proposed work is to provide a comprehensive design study and supporting analyses detailing one or more methods to suppress or eliminate periscope wakes. the approach consists of six separate technical operations: data collection and evaluation, signature definitions,… More

Microbubble Drag Reduction Demonstration

Award Year / Program / Phase: 2001 / STTR / Phase I
Agency / Branch: DOD / NAVY
Research Institution: PSU THRU ITS APPLIED RESEARCH LAB
Principal Investigator: Carol May, Senior Engineer
Award Amount: $70,000.00
RI Contact: R. Killoren
Abstract:
Cortana Corporation, ARL/PSU, and NAVATEK, propose to address the feasibility of performing a large-scale, seaborne demonstration of microbubble drag reduction (MBDR). A Cortana-led team has successfully demonstrated that a well-designed ejector and acarefully selected ejectant can increase the… More

Microbubble Drag Reduction Demonstration

Award Year / Program / Phase: 2002 / STTR / Phase II
Agency / Branch: DOD / NAVY
Research Institution: Psu Thru Its Applied Research Labs
Principal Investigator: Thomas D. Ryan, Principal Investigator
Award Amount: $399,454.00
RI Contact: Robert Killoren
Abstract:
"Specifically, we plan to use designs and hardware we have already developed for polymer ejectors to conduct a series of detailed experiments. From the perspective of prudence, we plan to reduce the risk and uncertainty in interpreting at-sea tests by firstconducting a set of experiments in the… More

Nonlinear Interaction of Impulsive Acoustic/Hydrodynamic Sources and Natural Ocean Inhomogeneities

Award Year / Program / Phase: 2009 / STTR / Phase I
Agency / Branch: DOD / NAVY
Research Institution: PSU thru its Applied Research Lab
Principal Investigator: John Pierce, Senior Scientist
Award Amount: $69,869.00
RI Contact: Robert L. Baker
Abstract:
The research will develop two physics-based models describing the generation of remotely detectable small-scale ocean surface roughness anomalies that can be produced by nonlinear interactions between impulsive acoustic/hydrodynamics sources and background ocean inhomogeneities. The first model is… More

Investigation of the Debye Effect for Submarine Detection

Award Year / Program / Phase: 2010 / SBIR / Phase I
Agency / Branch: DOD / NAVY
Principal Investigator: John Pierce, Senior Scientist
Award Amount: $79,948.00
Abstract:
This research will employ existing theories of the Debye Effect to estimate amplitudes of electromagnetic signals produced by a submarine operating in a realistic ocean environment. Estimates will incorporate known properties-mass, valence, volume, and friction coefficient-of each ionic species in… More

Nonlinear Interaction of Impulsive Acoustic/Hydrodynamic Sources and Natural Ocean Inhomogeneities

Award Year / Program / Phase: 2011 / STTR / Phase II
Agency / Branch: DOD / NAVY
Research Institution: ARL/Penn State University
Principal Investigator: John Pierce, Senior Scientist – (703) 534-8000
Award Amount: $743,090.00
RI Contact: Robert L. Baker
Abstract:
Phase II research will follow the most promising leads developed in Phase I, with the end goal of developing a viable physics-based model that can explain observations available to the Government. A dispersive focusing mechanism, supplemented by the theory of cylindrically-symmetric solitons, is the… More

Investigation of the Debye Effect for Submarine Detection

Award Year / Program / Phase: 2011 / SBIR / Phase II
Agency / Branch: DOD / NAVY
Principal Investigator: John Pierce, Senior Scientist – (703) 534-8000
Award Amount: $748,606.00
Abstract:
Cortana will review, analyze, and extend the published foreign work on electro-acoustic effects in the atmosphere. Specifically, Cortana will (i) incorporate contemporary understanding of the data on the relevant parameters for ions and charged aerosols in the planetary boundary layer, to model… More
