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 ...

We propose to develop scaling relationships for reaction violence in the cook-off of energetic materials such as explosives or propellants. This will be accomplished by a coordinated effort consisting of data review and analysis. The anticipated results include key non-dimensional parameters that incorporate the thermo-physical, flow, thermodynamic, and kinetic properties of the material, the heat ...

The proposed Autonmous Reactive Ferrrying Drifter (ARF-D) provides wide measured swath, autonomously maintains a buffer distance from close-shore snags, and by utilizing river flow provides a very low power approach to obtaining cross-river surveying, providing greater coverage with minimal power penalty. By randomizing the cross-river transit paths multiple ARF-D units will naturally overcome the ...

The Navy is developing an electromagnetic (EM) launcher for long-range naval surface-fire-support. Severe operating conditions of the EM system place stringent requirements for materials, including high current and magnetic fields, high temperatures, contact with liquid metals, high stress/gouging from balloting contacts and high-speed-sliding electrical-contact with an Al armature. Engineered Coa ...

The objective of this Project is to explore and develop refractory coatings on high strength, high electrical conductivity copper alloy, to enable damage resistant electromagnetic launcher. An electromagnetic launcher consists of two parallel copper rails, and a moving armature. High electrical currents passing through the rails and armature result in strong magnetic fields, high temperatures, che ...

Impact Technologies, in collaboration with Penn State Applied Research Laboratory, proposes to develop an advanced Battery Monitoring and Management System (BMMS) for lithium-ion battery packs that ensures adequate, safe, and reliable operation. This system will focus on real time diagnostics, prediction of catastrophic failure, and risk assessment for individual cells in high power applications. ...

Impact Technologies, in cooperation with Dr. Mohammed Daqaq from Clemson University, propose to develop a magnetostrictive materials based device for harvesting energy from mechanical vibration. The energy harvesting device will harness power from ship-hull vibrations in order to power sensing devices. This technology will be a key enabler for improved structural and machinery health management. K ...
