ABSTRACT: In this SBIR effort we will develop a packaging process and demonstrate (Phase I) a prototype of high power Photodiode (PD) that has a normal incident, pigtailed fiber input and a coaxial RF output that operates from DC to>60GHz. We will apply and extend (Phase II) the aforementioned packaging process to single PD, balanced PD and array of PDs that work from DC through entire W-band. De ...

ABSTRACT: The U.S. Air Force has a critical need for new robust strain sensors capable of accurately measuring the strain of structural components in high temperature harsh environment applications. During Phase I, Environetix will leverage extensive experience in wireless high temperature sensor materials, devices, packaging, and data acquisition, to develop and lab-test a prototype surface aco ...

ABSTRACT: The steadily rising cost of fossil fuels together with a heightened sensitivity to emissions has created a new backdrop against which the performance of traditional aircraft powerplant technology is no longer acceptable. Thermal efficiencies of current offerings hovering around 30% and below indicate that even modern turbine/turboprop engines are ready for game changing improvements. ...

Millimeter-wave RADAR imaging holds significant promise for many applications from rotorcraft DVE mitigation to standoff security screening. A key challenge of this imaging modality, however, has been the implementation of an effective method for creating an image without relying on either mechanical scanning or expensive, high SWAP phased array techniques. Herein, we present a concept for creat ...

ABSTRACT: This project aims to develop a Short Wave Infrared band image projector to provide real time detector stimulation with high dynamic range. Our emitter technology is based on GaInAsSb quaternary semiconductor LED arrays hybridized to CMOS read-in integrated circuits. This project leverages read-in circuit design and control electronics that were developed under SLEDS - a longer wavelengt ...

New enhancements to mobile computers including smaller sensors, displays and powerful processors have made them much more attractive for the battlefield, not only as wearable systems for soldiers, but also unattended ground sensors a warfighter can leave behind for situational awareness. Unfortunately, while the technologies for hands-free interfacing have improved greatly, the challenge of limiti ...

In this proposal, AlphaSense, Inc. details the development of a novel, low cost and handheld microwave sensor for the detection and evaluation of incipient composite heat damage. The merits of the proposed sensor and its advantages over other techniques are listed below: a) Compact, handheld and low cost, b) Sensitive for incipient heat damage detection, c) Capable of quantitative analysis of the ...

Parachutes are a vital technology for moving equipment, ammunition, and other supplies to the battlefield. Cargo parachutes are used to drop military equipment and supplies from aircraft. The U.S. Army currently uses Low Cost Aerial Delivery Systems (LCADS) parachutes for 99% of operational airdrops . These parachutes are made out of a low cost polypropylene material and are considered one-time-us ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

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 ...
