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 ...

The objective of this proposed Small Business Technology Transfer (STTR) effort is to develop an experimentally-validated, highly detailed chemical kinetic reference model of surface chemistry for C-SiC-SiO2 rubber composite materials exposed to high temperature, high pressure, oxidizing environments. This reference model will then be reduced into simplified reduced-order models that could be easi ...

Aerodyne Research, Inc. (ARI) and MIT are collaborating to extend their successful Phase I effort to fully develop and validate a comprehensive JP-10 combustion mechanism, using a novel automatic reaction mechanism generation tool (RMG) developed at MIT. JP-10 is a very attractive, but complex fuel whose combustion chemistry is poorly understood. In Phase I, the ARI/MIT team successfully developed ...

Leveraging on our extensive production experience in fiber optical components and fiber lasers, AGILTRON proposes to realize a new high pulse energy tunable blue laser with doped ZBLAN fiber. Based on enhanced blue upconversion by properly selected co-dopant materials, the proposed blue fiber laser will be able to generate high power. Furthermore, using beam combing technology, we will combine mul ...

different modes, while using different combinations of subsystems. This presents a challenge for the personnel validating the system during design and development; the number of combinations of environments, modes, and subsystems is exponential. They cannot all be tested, so an optimal subset of tests must be run. We propose to develop VERITAS: Validation and Evaluation of Remote, Interactive Tea ...

Vertical short takeoff and landing (VSTOL) operators face numerous challenges, particularly during takeoff, hover, and landing operations. Threats take the form of power lines, structures, and—in the case of combat—enemy fire. Often, these threats are obscured when visibility is compromised by dust, sand, or snow. Maintaining awareness of the surrounding environment becomes almost impossible. ...

Advances in modeling and simulation, networking, and computer graphics technology have made it possible to conduct large-scale, distributed live, virtual, and constructive (LVC) training events, such as the Navy’s Fleet Synthetic Training (FST) exercises, on a regular basis. However, FST exercises are not without room for improvement. Instructors and exercise controllers often confront difficult ...
