THE EFFICIENCY OF THE SCRUBBER ON THE HF HIGH ENERGY LASER WILL BE MEASURED UTILIZING FOURIER TRANSFORM INFRARED SPECTROSCOPY (FTIR). CONCENTRATIONS OF HF AND FLOWS WILL BE MEASURED BEFORE AND AFTER THE SCRUBBER, AND RECOMMENDATIONS MADE TO IMPROVE SCRUBBER EFFICIENCY, IF NECESSARY. AMBIENT AIR SAMPLING USING EITHER FTIR OR OTHER WET CHEMICAL METHOD WILL BE PERFORMED TO VALIDATE THE MODEL PREDICTI ...

Based on multiple technology platforms and theoretical analyses, in the Phase I program we have demonstrated the feasibility that RF polymers with desirable high frequency properties can be achieved. Following Edison¡¯s model of product and process development for technology innovations, Phase-II will pursue further incremental improvement in material properties upon the concept-proving materi ...

Both the Deep Skirt and Advanced Skirt System material used on Landing Craft Air Cushion (LCAC) experience significant wear during normal operations, which require expensive, time-consuming maintenance repairs. The US Navy is looking for innovative new material and manufacturing method for skirt systems to improve it durability and reduces Total Ownership Cost (TOC). Rubber skirts experience two m ...

Blisks are important in the design of modern aircraft engines. They offer attractive performance benefits, but due to their expense they require robust repair schemes, in order to avoid costly replacement during overhaul. The Laser Engineered Net Shaping (LENS) process has demonstrated repair of blisks without compromising mechanical integrity. LENS is an additive manufacturing technique, where ...

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 ...

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 ...

The Army is frequently forced to operate in hostile climates. Heavy fog, rain, snow, and dust storms can inhibit the performance of tracking technologies such as mid-wave infrared cameras. In such conditions, Army early warning systems are blinded and put personnel and assets at risk. There is a specific need for a degraded visual environment (DVE) penetrative target tracking solution. Radio fre ...

A TEST INSTRUMENTATION SYSTEM IS PROPOSED FOR THE DETECTION AND ISOLATION OF UPSET FAULTS PRODUCED BY TRANSIENT RADIATION IN VHSIC CLASS ASICS AND GENERAL PURPOSE MICROCIRCUITS. THE PROPOSED SYSTEM IS COMPOSED OF A HIGH SPEED WORK STATION, A PORTABLETESTER, AND A SEPARABLE TEST HEAD CONTAINING THE DEVICE UNDER TEST TO BE PLACED IN THE RADIATIONN BEAM. THE WORK STATION ACTS AS A CONTROLLER FOR THE ...

In this SBIR effort we will develop broadband, low V, high linearity, thin-film lithium niobate on insulator (LNOI) modulators that are fully compatible with silicon photonic integrated circuits (PIC) foundry processes. Developing such devices as well a

Continuous fiber reinforced ceramic matrix composites (CMCs) are desired for aerospace applications due to the strength and toughness imparted by incorporation of embedded long fibers of carbon or silicon carbide into a ceramic matrix. Oxidative degradation at high temperature is the predominant factor limiting the use of CMCs in jet engine applications. The components can swell when heated in ai ...
