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 ...

Recent advances in THz-source stability, power and practicality have opened the door for active THz imaging in both commercial and military settings. AEgis is teaming with U Buffalo to develop a THz detection device that utilizes classical rectification effects in semiconductor point contacts (SPCs) to achieve response in the 1 to 10 THz range and is capable of operating at temperatures over 150 K ...

The mission of this proposed research is to develop ultracapacitors (also known as electrochemical or supercapacitors) to address an array of military applications. These applications include pulsed power for directed-energy and kinetic-energy weapons, sensors, and power supplies and control systems for aircraft and spacecraft. The proposed innovation employs carbon nanotubes (CNTs) coated with p ...

AEDC personnel have developed and demonstrated the effectiveness of coupling a control volume model with a wind tunnel control system. The performance of the model was hampered because parameters of the model were assumed to be constant, when they are likely variables. A method for using facility data to determine functional relationships defining these parameters would allow them to vary during ...

Our objective is to develop advanced mediator architectures for efficient electron transfer in enzymatic fuel cells (EFCs) for low power systems. The proposed EFC will leverage ongoing research at both CFDRC and Michigan State University to provide a fully-integrated lightweight, low-cost, manufacturable, and renewable power supply, for various military and civilian applications. EFC systems offer ...

Higher efficiency solar cells are needed to reduce mass, volume, and cost of DoD space missions. However, to achieve higher efficiency and radiation hardness of the best to date multi-junction photovoltaic (PV) devices, several challenges must be addressed. This project aims to develop: 1) Quantum Well (QW)-based multi-junction cell that exhibits enhanced efficiency, and 2) Radiation-hardened PV c ...

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 ...
