Ceramic Matrix Composite (CMC)'s are highly susceptible to interlaminar shear failure at elevated temperatures. Therefore, interlaminar properties, critical design limitation of CMC should be assessed accurately with appropriate test methods to ensure overall structural reliability/integrity of components in Naval gas turbine engines. AlphaSTAR proposes to develop rigorous, precise, and innov ...

A diagnostic is being developed for aircraft engine exhausts that measures three velocity components in a slice through the plume. The method measures the Doppler shift of laser light scattered from particles naturally present in the flow, such as soot or dust. Two key areas of uncertainty were investigated in the Phase I study: 1) scattered light intensity from soot particles of sizes and concent ...

The Toyon-MST team proposes to perform research and development of a system which fuses multi-spectral EO and 3D data collected with a low-cost LIDAR to enable improved perception for unmanned ground vehicles (UGVs). The scope of the proposed work includes development of algorithms and software, and development, implementation, integration, testing, and delivery of a prototype, to perform EO-LIDAR ...

In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

Vescent Photonics proposes to develop a compact laser system and integrate it with a cold-atom micro primary standard developed under the DARPA IMPACT program. In phase I we will investigate performance enhancements resulting from immobilizing the cold-atom sample with an optical lattice formed from an optical field whose wavelength is chosen to minimize the differential light shifts between the s ...

MZA partnered with the University of Notre Dame proposes to conduct high-fidelity computational fluid dynamics (CFD) simulations providing volumetric time-resolved aero-optical disturbance modeling for rotary-wing aircraft flow dominated by wing-tip vortices. We will develop detailed wave-optics models of a baseline Navy helicopter beam director including engineering-level simulations of the beam ...

We propose to continue the development of software designed to model the propagation of light pulses through atomic media by including the capability to model propagation in optical cavities with active laser media, among other improvements. The software will be used to design and analyze a gyroscope based on the Sagnac effect that achieves enhanced sensitivity by employing a highly dispersive ato ...

The goal of this program is to develop and fabricate an ultra-low Size, Weight, and Power (SWAP) integrated electro-optic beam-steering technology that utilizes ultra-fast electro-optic active plasmonic waveguide arrays to achieve very wide scanning angle with diffraction limited beam quality. We develop a very scalable electro-optic plasmonic waveguides array that provides the electro-optic pha ...

The NAVY solicits new non-destructive inspection (NDI) methods to address detection and evaluation of kissing bonds and bondline integrity in aerospace composites since no currently accepted standard exists. In response AS & T Inc. propose, the Conformal Array Laser Imager for Bondline Evaluation and Repair (CALIBER), designed expressly for this purpose. The novelty of the proposed approach lies i ...
