This SBIR Phase I project is to prove the feasibility of an innovative weld monitoring technology. This innovative technology is characterized by (1) an innovative non-transferred arc sensor which responds to both surface conductivity and sensor-to-joint distance and can be used to monitor the joint geometry and possible surface contamination such as paint, oil, sand, etc. and (2) an innovative me ...

Gas Metal Arc Welding (GMAW) is the most widely used welding process. It is also the major process used in shipbuilding. In traditional GMAW and all its modifications, the current which melts the wire is the same as the current which heats the base metal. The base metal heat input is thus proportional to the heat which melts the wire. To maintain a minimally acceptable productivity as measured by ...

Orbital pipe welding systems are not true emulation of skilled welders who adjust welding parameters based on observation on the weld pool. This SBIR Phase II project aims at the development of commercial prototype systems which can adaptively adjust welding parameters based on an observation on the weld pool surface like a skilled welder but does not require the torch to be moved smoothly/evenly. ...

This proposal seeks to develop innovative technologies to enable accurate placement of sonobuoy stores from high altitudes. This will be accomplished through a combination of numerical predictive modeling improvements and decelerator design improvements. An emphasis is placed on developing technologies that are compatible with existing systems, reliable in all expected conditions, and low cost.

This proposal will investigate state-of-the-art sensor and propulsion technology and develop innovative design concepts compatible with the need to define and document a next-generation mobile ASW target simulator for Navy development. The research will explore active acoustic and non-acoustic sensor technology which is compatible with the severe packaging and cost constraints of airborne ASW exp ...

Traumatic head and neck injuries account for 16-33% of all war-related injuries and are a leading cause of mortality upon evacuation to a definitive care setting. Therapeutic advances are urgently needed for these soldiers. This application is focused on treating one of the most important determinants of outcome from severe head injury, the degree and duration of elevated intracranial pressure (I ...

The Full Authority Digital Engine Control (FADEC) controls engine operation. It is historically mounted on the engine case to minimize the routing length of the sensor and actuator wiring. The FADEC must be maintained below 63°C, while the environment can be as hot as 170°C. The current design uses fuel to cool the FADEC, however, this often limits the allowable ground or flight idle time bef ...

This Small Business Technology Transfer Phase I project will develop an innovative thermal solution to cool underwater acoustic projectors. More efficient cooling of the acoustic projectors will allow the devices to run at longer duty cycles, higher output powers and with longer service life. Current acoustic projectors use thermal conduction through the transducer parts to dissipate the waste hea ...

The proposed SBIR project will develop an innovative heat transfer mechanism involving dropwise condensation promoted by a non-wetting self-assembled monolayer (SAM) on a porous metal wick. Dropwise condensation on a bare surface has shown the ability to increase condensation heat transfer coefficients by orders of magnitude over film condensation. By condensing on a wick, heat transfer coefficien ...

Advanced Cooling Technologies, Inc. (ACT) will develop a Fast Thermal Response Fabric Test Setup for various thermal hazard scenarios involving convection (hot gas impingement by the jet engine exhaust), radiation (fire) and combination of convection and radiation (post-crash fire of aircraft, fire flash or bomb blast). The fabric test setup will (i) measure the thermal response of various clothin ...
