Award Data

Advances in electronically controlled injection technologies for diesel engines have provided a method to improve medium- to heavy-duty engine performance through increased injection pressures, multiple injections, and injection rate shaping. Although these injection systems have been primarily limited to larger engines, the ability to rapidly and precisely meter fuel for smaller engines is partic ...

The objective of this project is to develop a methodology for predicting reaction violence of full-scale munitions in either a fast or slow cook-off scenario. This methodology will use a combination of existing heat transfer models and thermal stimulus simulation tools coupled with an empirical model to be developed from data collected from various lab and subscale experimental hardware. Hardware ...

This proposal is being submitted in response to the solicitation topic N10A-T002 (Development of a Computational Method for Prediction of After Burning Effect) by BUSA Engineering Consulting (Dr. Jianghui Chao) in collaboration with University of Florida (PI: Prof. S. Balachandar). The overall objective of the proposed effort is to contribute to national defense and security by advancing the state ...

Nanotrons Corporation, in collaboration with Professor Byungki Kim at NSF Nanomanufacturing Research Center at the University of Massachusetts Lowell (UML), proposes to develop the low-cost high-rate manufacturing technique for flexible explosive detection sensors to significantly increase sensitivity of detection of trinitrotoluene (TNT) explosives. The new approach combines cutting-edge nanomate ...

Future naval operations are expected to make extensive use of unmanned vehicles to support a range of operations, including intelligence gathering, mine warfare, force protection, and anti-submarine warfare. Current unmanned systems are typically controlled remotely by an operator who directly manipulates a control interface for the vehicle. The effectiveness of this approach is obviously limited ...

Scientific Systems and Brigham Young University will develop and test an autonomous helicopter landing system using vision-based navigation and control.

Thermo-mechanical processes of turbine disks have been progressively improved to meet microstructural requirements tailored for advanced, sustainable high temperature performances. However, the chemistry of typical Ni-base turbine disk alloys is very complex, and yields a variety of phases and microstructural anomalies under different thermo-mechanical heat treatments. These microstructural hetero ...

In this STTR program, Photonic Systems Inc. and Prof. Jacob Khurgin at Johns Hopkins University propose novel optical external and internal fiber cooling approaches to efficiently cool the high power GaN microwave amplifier. The external cooler is a single end, square-shape, Yb:ZLAN fiber with high reflection (HR) coated surface which can attach to the amplifier surface and create a cold spot at t ...

Northwest UAV Propulsion Systems proposes using our purpose built heavy fuel engine designed and built in the USA for small unmanned aerial systems in the tier 2 & 3 class. We will be adding a lightweight ceramic material set combined with FEA (Finite Element Analysis) and heavy fuel atomizer (IRAD Project) to create a lightweight engine for a SUAS or STUAS class UAVs. The Ceramic material set is ...

The Navy seeks devices that can provide power to maintain charge in batteries for shipboard sensors. The transduction materials proposed for most energy harvesting devices under development are either too brittle to endure significant loading or are too compliant to extract significant energy from the small amplitude vibrations present on ships. Terfenol-D (in a composite form) and Galfenol each p ...
