Award Data

Advancements in optical transport and signal processing for digital and Microwave Photonics (MWP) technology have enabled higher bandwidth, throughput, Dynamic Range (DR), and communication link budgets. Optical transport eliminates heavy shielded twisted pair or coaxial cables, reducing Size, Weight, and Power (SWaP) and provides Electromagnetic Interference (EMI) immunity compared to traditional ...

Ingestion of silicate particles into aircraft gas turbine (GT) engines remains a serious hazard to both commercial and military aircraft. Helicopters and low-flying fixed-wing aircraft in desert environments are exposed to airborne sand particulate. Both commercial and military aircraft can be exposed to runway dust as well as high-altitude volcanic ash. These silicate particulates present a hazar ...

The Navy requires a low-cost, industrial microwave system for curing aerospace composite materials. In this Phase I STTR proposal, Physical Sciences Inc outlines the development of a microwave applicator that uses low-cost RF sources and can be installed in heritage autoclaves for curing large aerospace composite parts. This technology has the potential to improve cured mechanical properties, and ...

Physical Sciences Inc. (PSI), in collaboration with Stanford University, will develop an electromagnetic simulation package used for the development and optimization of large-scale meta-optics, and demonstrate the functionality of the package in the long-wave infrared (LWIR). Our team will combine recent progress in physics-augmented deep learning neural networks with rigorous far-field diffractio ...

In response to Navy STTR topic N23A-T010, Interphase Materials (IPM) in collaboration with the Virginia Tech Applied Research Corporation, propose the development of INTELLIPHASE, a sensor fusion and data analysis and software package, for the monitoring and prediction of the antifouling lifespan of TBTO in sonar radar domes. Sonar domes are necessary for optimal sonar performance, but require Tri ...

Physical Sciences Inc. partnered with Alfred University will develop an F/1, 90 degree full field of view MWIR/SWIR gradient index (GRIN) compound lens for reduced size and lens integration cost. The element-by-element achromatization and athermalization of GRIN provide useful performance improvements to GRIN systems. Element count is reduced (= 2), diversity of optical material needed is fixed, a ...

Physical Sciences Inc. (PSI), in collaboration with the University of Rhode Island, proposes to develop an advanced algorithm suite for data translation across sensing modalities to support the development of automated target recognition and classification algorithms for Unmanned Underwater Vehicles. The proposed Deep Diffusion Sensor Translation (DDST) leverages recent advancements in generative ...

Mainstream Engineering, in cooperation with the University of Massachusetts Lowell (UML), will develop and demonstrate a process to produce renewable JP-10. The process includes several reaction steps that begin with biomass-derived xylose. Our JP-10 process minimizes the number of reactors and will be continuous by integrating all the steps. To date, only one renewable route to JP-10 has been pro ...

Physical Sciences Inc. and Purdue University propose to develop a chemical model that accurately predicts the performance of hydroxyl terminated polybutadiene (HTPB) polymer commonly used as a propellant binder in rocket motors. The model will utilize chemical and physical data from HTPB feedstock to predict propellant cure kinetics, mechanical properties, and aging performance. The model will inc ...

This Phase I proposal will utilize multivariate regression, including cluster and principal component analysis to categorize lots of HTPB R-45M based on their physicochemical properties. Artificial intelligence-driven pattern recognition analysis will be performed on a variety of HTPB characterization data and spectra. Categorized data will be assessed against measured outcomes (pot life, mechanic ...
