21CT and CUBRC propose CEDAR (Complex Event Discovery, Analysis, and Ranking), a robust framework to detect and analyze indicators of complex activities, such as an insurgent ambush observable via myriad of simple events in multiple sensor streams. CEDAR will provide a mapping from complex behavior, such as conducting an insurgent ambush or rebuilding trust in local communities, to simple event in ...

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 ...

APS has assembled a world class team to address problems associated with rail gun launcher operation. APS has combined its unique processing experience with IAT's railgun design, testing and characterization experience to develop materials to improve rail gun performance. Phase I will be devoted to fabrication and testing of various samples in rail gun conditions. Phase II will focus on the manufa ...

The U.S. Navy has initiated a program to develop the next-generation Joint Counter Radio Controlled Improvised Explosive Device Electronic Warfare (JCREW) 3.3 system to detect and jam enemy improvised explosive devices (IEDs). The objective of this proposed effort is to develop the manufacturing processes and antenna designs needed to integrate a wideband metamaterial antenna within the ballistic ...

The promise of printed electronics can not be realized without high-speed manufacturing processes to drive the cost down for wide spread distribution. This proposal will outline the key points for rapid manufacturing of new electronic devices and systems and make recommendations for making them a reality. There are two main focus areas that encompass all the limitations to printed integrated circu ...

The purpose of this STTR is to develop comprehensive detailed kinetics for oxidation of C-SiC-SiO2-rubber in extreme oxidizing environment. This material is used as a coating on the outer surface of Navy weapon systems. In order to predict the fate of this material under extreme conditions and mitigate the degradation of the coating, a comprehensive oxidation mechanism is required. In Phase I, CFD ...

The objective of this proposed effort is to leverage state-of-the-art modeling and simulation tools to predict and assess the performance of a novel layered material system as protection for high-value missiles when deployed in launchers and canisters. The physics-based computational tools developed and used by Corvid allow for complex material interactions to be captured to provide an understandi ...
