Award Data

The 1.5 MHz to 35 MHz HF band supports a variety of functions (including ionospheric characterization and over-the-horizon communications) with relatively little infrastructure. The large antenna sizes required present a significant challenge that has prevented the adaptation of HF systems on small platforms. Small, low free-board maritime craft have an extremely small footprint and require a mini ...

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 ...

To address the DON’s need for developing methods to produce accurate riblet profiles in outer mold line (OML) surfaces that yield significant drag savings, fuel cost savings and extended range for USN aircraft, DARE Venture Group is partnered with MicroTau to deliver that exact development related to specific US Naval aircraft requirements. This project includes objectives encompassing the resea ...

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 today’s aviation world, decreased fuel and emissions are desired, while increased aircraft performance is also a priority.  Since decreasing aircraft drag can address both of these issues, it has received increasing interest.  Whereas reducing pressure drag through streamlining the vehicle has long been understood, reducing the viscous drag that accompanies the flow over any aircraft has be ...

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 ...
