The aluminum alloys have low density, relatively high strength, and high strength-to-weight ratio, which brings some major advantages in marine structure design, fabrication, and operations. However, marine ships are subjected to a complex and severe loading, and the typical failure mode of aluminum under extreme dynamics loading such as wave slamming and high velocity impact is ductile fracture. ...

Research is proposed for the development and implementation of state of the art computational and experimental tools for the investigation of the impact of control surface freeplay on the flutter and limit cycle oscillation characteristics of two-dimensional and three-dimensional wings in subsonic and transonic flow. Highly efficient and accurate aeroelastic simulation tools will be constructed ba ...

This Small Business Technology Transfer Phase I project is aiming at developing and implementing a multiscale composite model to predict the ceramic matrix composite (CMC) response to the impact loading by foreign objects. In particular, the physics-based model will be applied to describe the multiscale foreign object damage (FOD) phenomena of CMCs due to the complex nature of impact dynamics coup ...

Turbine disks are amongst the most critical components in aero- and naval-vessel engines. They operate in a high pressure and temperature environment requiring demanding properties. Nickel-based supperalloys which have high creep and oxidation resistance at high temperatures are widely used as the material of turbine disks. The elevated-temperature strength of this supperalloy and its resistance t ...

For the Phase I effort, a team comprised of experts in the areas of alternative high performance computing architectures such as the GPU, IBM Cell BE and Field Programmable Gate Arrays (Research Institution), and finite element analysis and continuum mechanics (Global Engineering Research and Technologies) has been formed to design and develop a framework and a library of algorithms optimized for ...

Abstract There is a valid scientific data paradigm where no loss of data can be tolerated. However, transmission of raw data requires unacceptable bandwidth and storage resources such that the net data received is uncomfortably low. Lossless data compression can be used to preserve all data with no information loss and also help meet bandwidth and storage constraints. The current Universal Sou ...

Internal combustion engines with power-to-weight ratios significantly higher than 1 Hp/lb which operate on low flash point fuels are enabling for powering Unmanned Aerial Vehicles (UAVs). Conventional Otto, Diesel and Wankel cycle engines even if constructed in advanced light-weight materials cannot meet the required power-to-weight and volume ratios and have high cost. A breakthrough in engine de ...

High strength copper alloys are preferred as the base rails for railguns due to their combination of strength and electrical and thermal conductivity, but suffer damage due to high current densities, arcing, gouging, and exposure to molten aluminum armatures. A refractory metal/alloy coating on the copper base alloy is an attractive approach for increasing rail life if the refractory metal coating ...

The Team of M-DOT Aerospace and University of Texas, Arlington propose to analyze, construct and test a 40 mm foil thrust bearing featuring a unique bump foil concept and top-foil profile designed by Dr. Daejong Kim. The design is simple, affording low production cost in high quantity. The design can be adapted for use on small gas turbines, small turbochargers and any small rotating machine that ...

We propose an all-fiber approach to heat removal from devices such as high-power RF amplifiers. In our approach, the cooling fiber segment, the pump fiber laser, and the optical fiber used for photon waste removal are all integrated into a single fiber configuration. NP Photonics' high efficiency thulium-doped fiber lasers are used to pump high purity thulium-doped glass fibers, which provide the ...
