In this Phase I Project ACTA and its partners will demonstrate the feasibility of developing a risk-based mission path planning (RB MPP) approach. Areas of interest to the Navy where a RB MPP address critical needs include enabling less restrictive UAS operations within the US National and Foreign Airspaces. The Phase I will demonstrate feasibility with a two-step approach. The first step will dem ...

We propose to mature LG-X glider technology by manufacturing full-scaled prototypes and characterizing them in land-based flight-testing by using commercial aircraft to drop the gliders. Validated components such as the landing parachute, folding wing mechanism, and autopilot control system will undergo integrated flight-testing. Logistic Gliders will provide a considerable cost share to support ...

Automatic speech recognition (ASR) technology is in wide use today and has been successfully integrated into a number of applications. Although there are also many potential applications for automatic speaker identification (SID), SID accuracy rates are generally not sufficient for widespread use in practical applications. For high accuracy ASR and SID, the microphone must be located near the talk ...

An advanced Li-Ion Battery Management System for DOD mission and safety critical platforms. The majority of Li-Ion Battery Management Systems (BMS) for DoD aircraft, helicopter, and directed energy weapons are custom designs for the individual Aerospace platform. This leads to increased cost over the battery life cycle due to the requirement to maintain the production facilities which produce repl ...

In this Phase II STTR effort, nGimat will partner with the University of Kentucky (UK) and 3M/Ceradyne to continue development of W-scandate cathode composite materials. Compared to conventional M-type cathodes, these composite scandate nanomaterials will enable longer cathode lifetime by lowering the required operating temperature. nGimat is an established and successful powder manufacturing comp ...

The proposed project will develop advanced modeling capabilities for hypersonic flow problems, specifically for predicting aerothermodynamic flow field for estimation of drag, thermal and structural loads, and for surface interactions. A quantum-to-continuum suite of tools that develop molecular relaxation models based on computational chemistry and quasi-classical trajectory (QCT) analysis will b ...

Candent Technologies is proposing a new axial flow waterjet propulsion system designed as a bolt on assembly that replaces the lower unit of the CRRC (Zodiac) existing outboard motor. This new replacement lower unit contains 90 degree gearing, engine cooling water pumping capability, and the complete new waterjet assembly. The latter is based on the high efficiency, low noise, low vibration waterj ...

There is a lack of quantitative tools to accurately map tissue viability in a rapid and quantitative manner so a surgeon can properly excise tissue prior to grafting. Spatial Frequency Domain Imaging (SFDI) is an optical method that has been shown to be a reliable method for physiology assessment - particularly for burn depth. SFDI measures of tissue structure (scattering) and function (hemoglobi ...

This Phase II effort aims to deliver robust, reliable software that instantiates state-of-the-art feedback pseudospectral optimal control algorithms for flight trajectory optimization. The computation and real-time implementation of controls in nonlinear systems remains one of the great challenges for applying optimal control theory in demanding aerospace and industrial systems. From proportional ...

The pseudospectral optimal control (PSOC) problem is used for rapid trajectory optimization and provides the ability to re-optimize during flight. This technology was implemented on a Navy-relevant mission, and pseudo-real-time operation was demonstrated. The technical readiness level at the end of the Phase I program is a concept that has been shown to be feasible using analysis and simulation. T ...
