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 ...

The development of technologies that advance military stealth and lethality in the face of notably increased aggression from U.S. adversaries is vital to maintaining tactical advantage. The U.S. Navy seeks to develop a ruggedized, quiet, transom-mounted, retractable electric propulsion system for high-speed planing craft - Special Operations Craft – Riverine (SOCR). The proposed Auxiliary Propul ...

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 ...

There is a critical need for a high purity commercial source of calcium lanthanum sulfide (CaL2S4; CLS).  Ceramics made from CLS have an unusually broad range of transmittance in the infrared (IR), as well as high mechanical strength and environmental durability.  For these reasons, CLS is an ideal material for IR windows used in applications such as multispectral imaging.  CLS ceramics are not ...

Lorad Chemical Corporation (“Lorad”) has developed nano-scale high-purity Calcium Lanthanum Sulfide ("CLS") powders suitable for fabrication of near theoretical density infrared ("IR") transparent domes, windows, lenses, and other parts. CLS incorporated into optical components and domes / windows has several applications in IR optical sensing systems and IR lenses for laser applications. ...

Additive Manufacturing provides many potential advantages, relative to traditional manufacturing methods, for the Navy and other organizations in the aerospace community.  Although flight critical aerospace quality metal alloy components have been produced and flight tested, confidently expanding the use of AM in these applications requiring stringent quality control and repeatability. The vendor ...
