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 ...

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 ...

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 ...

ABSTRACT: As the size, cost, and power consumption of digital signal processing platforms continue to drop and their performance improves, incorporating digital beam-former (DBF) designs into future SATCOM satellite payloads has become an increasingly attractive option. The advantages offered by digital beam-forming stem from the ability to create composite antenna patterns that vary with both s ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...
