In traditional GMAW and modifications, the current melting the wire is the same as the current heating the base metal. To maintain a minimally acceptable productivity, the base metal heat input is typically much greater than the required to control the distortion at an acceptable or desirable level. In the modified GMAW proposed, a bypass torch is added to an existing GMAW system to bypass part of ...

Research is proposed for the development and implementation of state of the art, reduced order nonlinear aeroelastic models for multidisciplinary/multi-fidelity optimization problems. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution met ...

This SBIR aims at developing a high-fidelity, yet efficient and easy-to-use, composite rotor blade and wing section design environment to facilitate rapid and confident aeromechanics assessment during conceptual design stages. A well-known technical barrier for composite rotor blade and wing section design is the lack of a user friendly, efficient and high-fidelity design tool to realistically rep ...

One of the challenges of helicopter cargo missions is dealing with external slung loads. During flight, these loads often move in complex ways driven by forces generated by atmospheric effects and the helicopter’s downwash. A low-cost, accurate and airworthy system for measuring the load’s motion could allow for direct slung load stabilization by providing feedback to a human pilot, flight com ...

The AEgis Technologies Group Inc. proposes to investigate high energy laser and high power microwave instrumentation for ground and airborne targets. The experienced team will identify candidate instrumentation systems; evaluate them against customer-defined requirements and features; and recommend potential systems for further study, development, and implementation in Phase II. We will coordinate ...

The technology, theory and fabrication of artificial materials and metamaterials have seen impressive progress in the last few years, and various applied fields have benefited of the great flexibility of electromagnetic response that metamaterials may provide at microwaves, infrared (IR) and/or optical frequencies. Negative-refractive and zero-permittivity metamaterials have indeed been proposed f ...

The objective of this Phase II proposal is to build a solid-state all-electronic beam steering system designed for laser radar (LADAR) beam steering. The system will employ two primary components: 1) a high performance electro-optic (EO) device to steer a laser beam and 2) a passive “superprism” that amplifies the EO steering angle. The superprism is a breakthrough technology that uses a phot ...

Radio systems play an increasing role in our military and civilian infrastructure, and many of these systems are vulnerable to accidental and malevolent electromagnetic attack. Malevolent EMI attacks on aircraft are not a new threat, and will probably increase in our society due to wide spread availability of electronic hardware and the increasing use of wireless devices. Protection from laser thr ...

Surface plasmons (SPs) have been studied by a wide spectrum of scientists, ranging from physicists, chemists and materials scientists to biologists. Plasmonics represents an opportunity to develop a new class of photonic devices by concentrating and channeling light using subwavelength structures. Such circuits would first convert light into SPs, which would then propagate and be processed by lo ...
