Viscosity and low temperature lubricant characteristics determine turbine engine starting capability, and lubricant motion with respect to the contact surfaces at low ambient temperature. Such low ambient temperatures influence the oil viscosity and also the variation of its curve shape versus the temperature. According to the aforementioned research method, the requirements for accuracy and rel ...

This Phase I project will evaluate the feasibility of high-speed microscopic imaging and statistical correlation velocimetry to determine the particle size and velocity in solid rocket motors. Statistical correlation velocimetry relies on obtaining an ensemble of high-speed videos of turbulent flows (both reacting and non-reacting). These videos are analyzed using a statistical correlation techn ...

This program will improve the size, weight and efficiency of power generators by integrating a lightweight, high efficiency alternator with a quiet, fuel efficient and high power density heavy fuel engine. It will be capable of meeting DoD needs for reliable and efficient propulsion and power systems for unmanned aircraft, ground and maritime systems. The electrical power source will use a propr ...

Energy management in missile systems can provide substantial performance advantages, especially for modern missiles capable of all-aspect engagements. Maximum flexibility is offered by a system that can be throttled, shut off entirely and restarted when needed. The proposed project aims to achieve efficient combustion during throttling and restart capability without the need for a separate ignit ...

The potential for combustion instability has historically been a hindrance in developing rocket engines, and nearly always represents the major technical risk in engine developments. This proposal addresses innovative approaches toward prediction of liquid rocket engine combustion instability, as well as innovations in full-scale engine stability verification. Specific objectives are to demonstrat ...

Despite the importance of jet fighter afterburner designs, there exists very little data on the majority of the individual components of jet fuel, especially JP-8, to enable development of a detailed kinetic mechanism. Although the Multi University Research Initiative program has been initiated for that purpose, it is oriented for the main engine combustor where the process is different from afte ...

The U.S. Navy has researched the use of various acoustic sensing technologies that exploit the deep water reliable acoustic path (RAP) using vertical line arrays (VLA’s) of vector sensors with success. The buoys used were, however, large, over-the–side deployed, research systems to demonstrate the approach. What is desired is a viable approach that is smaller and can be ideally packaged to fa ...

The Navy desires the use of RHIB’s in littoral waters for MCM because of its many advantages. However, these advantages can only be accomplished by providing a towed minesweeping approach that allows the RHIB to adequately perform the required mission within its limited towing capacity. The Phase I program established a baseline approach for an electrically driven, towed Acoustic Source that was ...

Energy extraction is needed for various ocean deployed devices. Extracted energy can be expected to be at various levels and intermittent, but plentiful. The Phase I effort will recommend an extraction technique that directly converts ocean energy into electrical power. The extractor will be inherently self-starting, require no external inputs from the crew when deployed and produces enough power ...

In both the commercial and military electronics markets, there is a continuing trend to reduce size, weight, and overall equipment costs, while at the same time increasing functionality and improving reliability of the electronic circuitry. Integrated circuit manufacturers have addressed this need by integrating greater functionality directly onto the silicon chips, thus yielding the System-on-Chi ...
