The goal of this proposal will be to demonstrate the viability of a micro tube heat exchanger in an HVAC application on board a Navy vessel. Specifically, a product design sequence will be completed, resulting in R-134a economizer that will provide volume and weight savings over existing technologies. The program will include tasks to test the strength and overall structural properties of the head ...

A major barrier to the widespread adoption of wireless sensors for structural health monitoring is the requirement to power the network of wireless nodes. Batteries have a limited lifespan, adding significant size, weight, and costs to the wireless sensor network,and may represent a long term environmental problem. Battery maintenance can be eliminated by harvesting energy from the environment. Fo ...

Structural monitoring of Navy aircraft is of critical importance as the fleet ages. One critical area includes the control surfaces, which are subject to intense, dynamic buffet loading which can lead to structural cracking. The highly transient nature of buffet loading makes it difficult to measure using conventional sensors. We propose to solve this problem by combining a network of time-synchro ...

Mezzo Technologies is currently developing an extremely compact, sturdy cross flow heat exchanger that is particularly effective in a variety of applications. The goal of this project is to optimize current panel design and configuration technology for use on the F-35/JSF aircraft, and examine the overall weight and volume gains by replacing plate fin heat exchangers currently used with Mezzo's c ...

The hybrid-electric technology being developed by LRG in this Phase II effort is a key enabling technology for the U. S. Navy. This hybrid electric drive train will provide a foundation for further research and development into electric propulsion, payloads requiring electric power, and high-speed hull design based on electric propulsors. This hybrid electric drive system will also support the d ...

The goal of this Phase I SBIR proposal is to design and build energy harvesting wireless sensing systems suitable for use aboard Navy Helicopters. The program will begin with a survey of typical vibration data obtained during flight testing; these data will then be used to optimize our existing vibration energy harvesting wireless sensors (VEWS) for use on Navy helicopters. These software progra ...

SCOUT (Sensor Coordination for Optimal Utilization and Tactics) is a Neptune Sciences, Inc. project that solves a multi-static active sonar optimization problem in an arbitrarily complex environment. SCOUT combines several techniques to identify optimal locations and “ping” times for a discrete set of active sonars and receivers in a complex propagation environment. The Phase I results invol ...

The objective is to determine the best algorithmic approach to optimally select unmanned vehicle flight paths that maximize mission success for attached sensors. That involves trade-offs between a) active emissions and passive collections, b) high and low altitudes, c) high and low speeds, d) day and night operations, e) rough and smooth terrain, f) accuracy and efficiency, etc. The solutions wi ...

Since the Second World War, increased performance has been acquired by investing heavily in expensive new sensor hardware, including advanced off-board sensors, at the near exclusion of developing new algorithms and tactics to optimize use of sensors in complex environments. The shift toward threats in just such hostile areas demands a more synergistic approach wherein new sensors breed new tacti ...
