Investigations into JP-10 combustion chemistry thus far can be characterized as preliminary. The detailed chemical kinetic mechanisms that have been published are limited in their ability to reproduce experimental data. The combustion chemistry of JP-10 is highly complex, involving hundreds if not thousands of species and thousands of chemical reactions. A detailed kinetic model capable of predict ...

This Small Business Technology Transfer Research (STTR) Phase II proposal from Materials and Systems Research, Inc. (MSRI) and University of Utah (research institution) seeks to fabricate single-phase, polycrystalline tungstate ceramics with densities greater than 99.95% and a mean grain size of less than 1 um. These ceramics have been chosen because of their low thermal expansion and low elastic ...

Catastrophic failures in aircraft electrical power systems can compromise the readiness, safety, and capabilities of the war-fighter. In this effort, a multi-physics suite of tools will be developed based upon the successful Phase I research to provide a comprehensive prognostics and health management system (PHM) for aircraft generators and associated electrical systems. The PHM will be based upo ...

Although numerical analysis applications have proven to be effective and reasonably accurate, the effort required to develop the associated analysis models remains a challenging and time consuming task. While many meshing tools are currently available, decomposing and manipulating the design geometry and enhancing the topology for mesh construction are manual processes and place the heaviest dema ...

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 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 ...

This Small Business Technology Transfer (STTR) Phase II project aims to develop a manufacturing process to synthesize metal oxide, sulfide and other nanoparticles. The subject method simply involves mixing of common dry chemical starting materials and heating the resulting precursor material to a modest temperature. The objective is to demonstrate feasibility and scalability of this low-cost man ...
