Viscosity and low temperature lubricant characteristics determine turbine engine starting capability, and lubricant motion with respect to the contact surfaces at low ambient temperature. Such low ambient temperatures influence the oil viscosity and also the variation of its curve shape versus the temperature. According to the aforementioned research method, the requirements for accuracy and rel ...

We propose real time, compact hardware implementation and integration of sensors, algorithms, and processing hardware for extracting 3-D imagery and absolute range from visible and/or infrared (IR) images collected from small UAVs or situational awareness sensors. The proposed approach can be used for 3D structure reconstruction, scene interpretation, and 3D visualization. Sensor/ system will use ...

In order to address the NASA lunar mission, DESC proposes to develop a proton exchange membrane (PEM) closed-loop pure oxygen fuel cell for application to lunar surface exploration, building upon DESC's expertise and fundamental demonstrations in closely related technology. Building upon the Phase I project, the static feed fuel cell hardware will be scaled up approximately three times in active a ...

The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

The potential benefits of Large Eddy Simulation (LES) for aerodynamics and combustion simulation hvae largely been missed, due to the complexity of generating grids for complex topologies, and the requirement for boundary fitted grids which reduce the accuracy of the method. The Phase 2 Program builds on the Cartesian grid LES flow solver developed under Phase 1, and includes new techologies such ...

The primary objective of the proposed work is to develop a directed energy system analysis and design environment. This analysis and design environment will be based upon Distributed Heterogeneous Simulation (DHS) and Distributed Heterogeneous Optimization (DHO) technology. DHS allows the interconnection of models developed in different simulation languages running on different computing platfor ...

The primary objective of the proposed work is to investigate design techniques to improve torque density, power density, and efficiency in wound-rotor synchronous machines. The underlying principle of the proposed design technique is to alter the flux paths in the machine to increase torque production. This will be achieved through optimally altering the stator tooth geometry, rotor tooth geomet ...

Fault detection and isolation (FDI) in spacecraft's electrical power system (EPS) has always received special attention. However, the power systems health management techniques have generally been limited to the energy sources and storage elements. Furthermore, these functions have been performed off-line by mission planners for the sole purpose of estimating future energy availability and effec ...

SHOT’s innovative design for a deeply buried hardened target fuze incorporates the use of a non-inertial proximity sensor as a solution to the shortcomings of existing accelerometer –based smart fuze designs. The proposed sensor is compact, relatively low power, and can easily be adapted to a wide variety of proximity sensing problems in retrofit adaptable form factors. SHOT’s proposed desi ...

Based on multiple technology platforms and theoretical analyses, in the Phase I program we have demonstrated the feasibility that RF polymers with desirable high frequency properties can be achieved.
