In this proposal, AlphaSense, Inc. proposes to develop an innovative real time probe for online monitoring of plastic bonded explosive manufacturing process. Key innovations of the proposed sensor probe include: a) the use of a white light interferometer (WLI) to form real time images of the particles for accurate particle size measurements, and b) the use of quartz crystal microbalance (QCM) base ...

Mid-infrared (MWIR, wavelength ~10 micron) imaging has significant importance in military surveillance and target recognition, since human body radiation peaks in MWIR. The GaSb/InAs type-II Strained Layer Superlattice (SLS) MWIR detector has been under intensive investigation recently. While much progress has been made to enhance wavelength coverage, one of the few remaining issues has been its r ...

Low light level infrared imaging has significant importance in military surveillance and target recognition. The proposed broadband low-light-level nano-BiCMOS camera covers visible and near infrared bands from 400 nm to 1,550 nm wavelengths. With a proven nano-technology, the proposed nano-BiCMOS photo-detector solves this long-standing tradeoff between quantum efficiency and dark current by in- ...

A novel system for the measurement of rotor states is proposed for development, to be used as part of a control system in the support of advanced helicopter (and tiltrotor) handling qualities and flight dynamics improvements. The design builds on extensive prior rotor instrumentation work that has supported numerous wind tunnel testing research programs, but adds robustness and fault-tolerant fea ...

Fast, accurate computational models of rotorcraft aerodynamics and dynamics are critical for analysis and design. The strong coupling between aerodynamics and dynamics characteristic of rotary-wing aircraft greatly complicates the task of comprehensive rotorcraft analyses aspiring to this goal. Over the past twenty-five years, the core focus of Continuum Dynamics, Inc., (CDI), has been to develo ...

Accurate performance prediction is critical to rotorcraft design and development, and while significant gains have been made in rotorcraft CFD-CSD methods, predicting unsteady wake aerodynamics remains a significant challenge. Current analysis tools can theoretically model the complete rotorcraft, but are hampered by modeling assumptions (for Lagrangian methods) and numerical formulation (for CFD ...

We propose to demonstrate a photonic radio-frequency (RF) arbitrary waveform generator (AWG) having (1) 3 dB bandwidth = 10 GHz, (2) time aperture > 2 ns (time-bandwidth product > 20), and (3) maximum RF output amplitude > 3 V. This performance will be facilitated by our proposed highly linear, high-power 10 GHz bandwidth photodiodes which will deliver > 3 V peak RF amplitude, thereby enabling a ...

The essential step in the manufacturing of electronics systems involves soldering components to printed wiring boards. Copper and other metal leads to be soldered must be protected from oxidation during storage. Preffered protective coating for over fifty years was tin-lead solder. With passage of RoHS Directive that increased pressure to remore lead from electronics assemblies, new coating must b ...
