This SBIR project aims at the development of an innovative technology that can be attached to existing submerged arc welding (SAW) systems to monitor and feedback control the depth of weld penetration. Existing SAW systems will be operated using existing welding procedures without modifications. In many applications skilled welders may adjust the welding parameters based on their observation of dy ...

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 ...

A novel method of fabricating carbon nanotube (CNT) reinforced polymer matrix composites is proposed. It includes growing super-aligned carbon nanotube arrays on a flat substrate, using NCSU proprietary shear pressing method to compress the grown arrays into a layer of densely packed, highly aligned CNTs inclined at an angle of several degrees to the substrate, separating the produced CNT sheet fr ...

This Phase 1 SBIR project will establish the technical and commercial benefits of using previous task executions to augment model-based route planning for military applications. On this project, we will integrate a prototype route planner using ``Implicit Semantic Knowledge'' (ISK) derived from previous executions, with an existing model-based route planner, called ``Ground Guidance.'' Model-bas ...

For Phase I, an ultra low power, high performance microprocessor core using a combination of double-gated and independent double-gated Flexfet™ SOI CMOS technology from American Semiconductor will be designed to address the requirements of military and space communication systems. High integration feasibility using Flexfet technologies followed by confirmation of the power and performance improv ...

A radiation hardened via-configurable analog array (RHVCAA) is proposed to provide a rapid prototyping mixed signal platform for implementing radiation hardened and high performance custom analog system designs. In phase I the feasibility of implementing RHVCAAs was investigated. Existing Triad semiconductor VCAA technology was assessed to determine modifications required to comply with radiation ...

The physical phenomena that dominates the use of submillimeter (SMM) spectra for the analysis of missile intercepts is the rapid cooling of the post-intercept gas and debris field and its impact on the SMM spectral signatures and post-impact chemistry. It is likely that the initial high temperatures and density will result in a molecular soup that is much more complex than the atomic mixtures tha ...
