Diminishing domestic helium supplies and a growing dependence on foreign sources of helium, such as helium produced in Russia, have created severe shortages of this critical gas for various facets of the U.S. economy, including medicine, research, manufacturing, and consumer goods. This proposal aims to address this vulnerability in the U.S. supply chain through the development of a novel family o ...

Historically, active materials (Navy Type III) used in compact, low cost Navy sonars, such as A-size sonobuoys have moderate d33 and low loss factor. Recent developments in lead-based textured ceramic with properties between those of conventional PZT ceramics and relaxor single crystals can improve the performance of these systems, but need to be manufactured at high volume and low cost. Most appr ...

This program will address antenna design characteristics which can reduce the size of HF antennas for the small maritime craft while providing increased instantaneous bandwidth to provide higher data rates with higher reliability. We will apply our extensive HF experience in wideband HF ground/airborne antenna development coupled with previous efforts in conformal antennas on unique platforms to a ...

The benefits of riblets on reducing drag has been established and reverified over the years since the technology’s inception in the 1980s. Unfortunately, transitioning riblets from machined aluminum panels to a format that can be utilized for large scale aerospace applications has been unsuccessful. Applique riblet films required significant application time and specialized workers. Utilizing ph ...

In the proposed effort, we will develop a method to produce accurate riblet profiles in outer mold line (OML) surfaces that significantly reduce viscous drag, require little or no maintenance, are inexpensive to apply or include in production or normal maintenance, and achieve long useful life, yielding fuel cost savings and extended range for military and civilian aircraft.

Triton Systems proposes to develop a Silent, Deployable, and Rugged Ocean Propulsor (S-DROP) for use on small naval combatant craft. S-DROP will provide a secondary propulsion system for silent running stealth operations in a modular, cross compatible, and scalable package without compromising existing systems. S-DROP incorporates extreme ruggedness and acoustic quieting techniques with high perfo ...

The Navy utilizes small, crewed watercraft, e.g., the Special Operations Craft – Ravine, for a range of missions in the littoral zone. These watercrafts, while designed for high-speed operation, also require low-speed stealth operation to successfully complete all types of mission objectives. However, the existing internal combustions engines and propulsion systems currently used on these vessel ...

Candent Technologies has successfully developed a low cavitation, high efficiency, extremely low acoustic signature marine propulsor, and is proposing to apply this advanced technology to the design and development of a compact, efficient, electric driven, stowable/retractable, Quiet Auxiliary Propulsion System that will meet and likely surpass the requirements for the SOCR (and 11m RHIB, as well ...

Calcium lanthanum sulfide is an infrared transparent ceramic with many desired properties including its high temperature optical and mechanical properties and its potential use in designing new multi-band optical components.  However current production methods for calcium lanthanum sulfide are relatively immature and often contain impurities that limit optical performance of the produced powders. ...

Calcium lanthanum sulfide (CLS) is a well known ceramic material that can be used in infrared optics for spectroscopy, imaging, and optical components of medical equipment. While CLS is a useful infrared transparent ceramic, the lack of a reproducible and dependable manufacturing process remains a significant hurdle to realizing its full utilization. The poor reproducibility is associated with var ...
