ABSTRACT: The Air Force is seeking a compact, high torque, rotary EMA technology capable of controlling flight control surfaces directly at the hinge line in the next generation of thin-wing aircraft. Proposed for this application is an advanced EMA technology based on an axial flux, permanent-magnet machine structure. The unique shape of this device enables efficient integration into the wing ...

ABSTRACT: For this SBIR topic, we have proposed a novel high-power optical fiber pump combiner design that addresses the specific challenges associated with counter-pumping large-mode-area (LMA) double-clad gain fibers. Based on modeling and design optimization, we will fabricate kilowatt capable power combiner prototypes for pump coupling to double-clad Yb-doped polarization-maintaining (PM) fi ...

GaN-based devices are currently grown on foreign substrates such as SiC and Al2O3, due to the lack of high quality GaN substrates. It is well known that the use of foreign substrates limits device performance due to a high dislocation density in the GaN film. Structured Materials Industries, Inc. (SMI) has developed a hybrid HVPE approach to grow high quality GaN device films. In this SBIR proj ...

The movement to more-electric architectures during the past decade in military and commercial airborne systems continues to increase the complexity of designing and specifying the electrical power system. The addition of numerous high-power electric loads has drastically altered the dynamics of power flow on the electrical bus. Many of these loads often exhibit peak-to-average power ratios in ex ...

ABSTRACT: The move towards more-electric aircraft continues to increase the complexity of electrical power systems (EPS) on modern airborne platforms. In addition to ever expanding peak and regenerative power demands, several of the loads can introduce very high rates of current change (dI/dt) within the EPS, all of which implies significant spectral power across a wide range of frequencies. Re ...

ABSTRACT: It has been a challenge to realize the benefits of energetic metal nanoparticles due to the severe oxidation that occurs on the particle surface, which leads to significantly diminished performance during combustion. We propose to improve the energetic properties and air-stability of aluminum nanoparticles by encapsulating them with a relatively noble metal that can undergo an exothermi ...

ABSTRACT: Foresight Wireless, LLC, proposes a novel access control system, Proximity/Risk Ontology-based Access Control Technology (PROACT), to meet the Air Force objective, namely"develop a standards-based access control mechanism that will dynamically adjust data access for individuals based on their proximity to others/organizations in terms of attributes (e.g. location, mission, assignment) d ...

The Navy is interested in developing high power and high operation efficiency pumps at 808nm for multiple Navy applications. VCSEL technology offers an excellent choice for the development of such laser pumps. Princeton Optronics has developed the technology of high power VCSEL arrays delivering hundreds of watts of power from small chips with>55% efficiency at 976nm. We would use improvements of ...

ABSTRACT: We propose to demonstrate the benefits of a self-healing coating (SHC) system (comprised of MIL-PRF-85285 compliant self-healing top coat; MIL-PRF-23377 Class N primer; chromate-free pretreatment) on repaired and restored aluminum. Innovations are proposed for a self-healing polyurethane-based top coat that satisfies the functional performance requirements for the present application. T ...
