The rotorcraft aerodynamic interaction is a complicated problem and remains an extremely challenging aspect of rotorcraft analysis. This STTR is dedicated to developing a solution for the complicated rotorcraft aerodynamic interaction problem. The Phase I research coupled a state-of-the-art vortex particle method (VPM) with an unstructured Navier-Stokes CFD body surface solver and prototyped a hyb ...

Advanced Scientific Concepts, Inc. (ASC) has teamed with the Department of Ocean Engineering at The University of Rhode Island to devise a sensor suite and computer algorithm to predict ocean waves to aid autonomous boat navigation in heavy weather. The centerpiece of the sensor suite is a Lidar designed by ASC that is adapted to image the ocean at glancing angles. It’s ability to acquire a 3D s ...

Military operations in urban areas have increasingly become a key capability for our armed forces. The increased risk of use of the unique nature of large urban environments by hostile forces to their tactical advantage, and related civilian casualties, requires updated procedures, comprehensive training, and constantly evolving capabilities. Current training technologies fail to address the signi ...

Applied Physical Sciences and the University of Maryland propose to develop a magnetostrictive transducer that harvests electrical energy from shipboard machinery while simultaneously suppressing vibration to improve the ship’s stealth characteristics and thereby improving the performance of hull mounted sonar systems. Analysis performed during the Base Effort will provide an initial design spec ...

Applied Physical Sciences (APS) and the Pennsylvania State University Applied Research Laboratory (ARL/PSU) will collaborate in the development of a novel sensor system to measure the low frequency acoustic pressures within a fluid-filled pipe. The proposed concept improves upon the Navy’s current Array Based Acoustic Measurement (ABAM) system for laboratory characterization of full-scale piping ...

Transphorm proposes to demonstrate a normally off fast high voltage Gallium Nitride power switch solution. The switch would block to 1200V, have a threshold voltage greater than 5 V, and the phase 2 switch will target an on resistance less than 15 ohm-mm and current more than 1 Amp. To accomplish these targets, Transphorm will combine the design requirements of realizing a high (and positive) thre ...

Although many off-the-shelf and semi-custom Battery Management Systems (BMS) are available, the Navy recognizes with this STTR Topic, and recent history illustrates, that a safety system with the required reliability and performance for mission critical applications has not been demonstrated. This proposal will detail the Spectral Labs Incorporated (SLI) and University of California, Davis (UCD) t ...

In today’s information age, there are vast resources of data on every region of the Earth. The application of geospecific imagery over large areas has been limited to terrain for the most part. The hindrances to full use of geospecific imagery are the labor required to create the databases, and limits on the rendering capacity of current image generators (IGs), both in polygon count and texture ...

Small combat dive teams require a situational awareness capability that combines robust, low probability of detection (LPD) communication with navigation/tracking functions. The project will result in a compact terminal for underwater acoustics based communication, navigation and tracking. The Diver Messaging and Navigation Terminal (DMNT) will be rugged and easy to use, warranting a description ...

The proposed STTR will demonstrate how magnetic meta materials based antennas are ideal for integration into composite structures where the graphite composite backplanes can be integrated with dielectric ballistic protection materials that surround, yet do not interfere with the antenna. In ongoing research we have shown such antennas can approach the theoretical Gain-Bandwidth Product (GBWP) limi ...
