Accudyne proposes a SBIR program, endorsed by Sikorsky, Cytec Engineered Materials, and NASA-LaRC, to develop a cost-effective thermoplastic automated tow placement (ATP) process and demonstrate it by fabricating and testing a complex contoured skin (Phase 1) and a CH-53K rotorcraft lower cabin or ramp skin (Phase 2). The process employs in situ consolidation, avoiding the autoclave. The targete ...

This proposal will supply to NAVAIR and to rotorcraft manufacturing companies the emerging solution to their fabrication needs as it relates to the production of Rotor Blade Spars. The process and machine concept developed in Phase I will provide NAVAIR and the rotocraft manufacturing companies an automated solution to spar manufacturing. This will enable: • Low part manufacturing cost • High ...

This SBIR Phase I project is to prove the feasibility of an innovative weld monitoring technology. This innovative technology is characterized by (1) an innovative non-transferred arc sensor which responds to both surface conductivity and sensor-to-joint distance and can be used to monitor the joint geometry and possible surface contamination such as paint, oil, sand, etc. and (2) an innovative me ...

Gas Metal Arc Welding (GMAW) is the most widely used welding process. It is also the major process used in shipbuilding. In traditional GMAW and all its modifications, the current which melts the wire is the same as the current which heats the base metal. The base metal heat input is thus proportional to the heat which melts the wire. To maintain a minimally acceptable productivity as measured by ...

Orbital pipe welding systems are not true emulation of skilled welders who adjust welding parameters based on observation on the weld pool. This SBIR Phase II project aims at the development of commercial prototype systems which can adaptively adjust welding parameters based on an observation on the weld pool surface like a skilled welder but does not require the torch to be moved smoothly/evenly. ...

The objective of the proposed research aims to develop Reduced Order Models (ROMs) (i.e. POD, HB, combined POD and HB) based upon flight data to better predict the aircraft aeroelastic response at next flight condition, e.g. higher Mach number. By incorporating flight test data and using the highest fidelity computational models in reduced order form we will obtain computational solutions that a ...

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 an efficient, user friendly, high-fidelity design tool to realistically repre ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

ANP Technologies proposes to integrate a commercially available air sample concentrator from ICx MesoSystems with our automated detection instrument that uses the NIDS® multiplexed assays and NIDS® Auto-Reader (AR) device. A trigger device may also be incorporated into the final system, which might better enable the system to serve as a remote monitor of air streams. The proposed effort will b ...
