BIOCIDAL POLYMERS FOR DENTAL WATER CONTAMINATION CONTROL

Not Available The typical mission requirements of supersonic and hypersonic flight impose complex aerodynamic and thermal loads on the airframe structure These multidisciplinary problems currently require inefficient interfacing between analysis groups to solve. This proposed effort will ascertain the feasibility of coupling the aerodynamic and thrill load calculation analysis codes with structural response codes, tailored toward high speed flight. To minimize cost, current and past efforts of the Army, Air Force, Navy, and NASA will be thoroughly considered, since the software developed under their efforts is generally freely available to US government and industry users. A number of existing flowfield and heat transfer analysis codes will be evaluated. The evaluation process will assure accurate and robust prediction methods for a variety of systems. Among the physics to be included in the chosen codes are real gas effects, free molecular and transition regime flow, enhanced heating near aerodynamic control surfaces, weather effects, and ablation. An integration routine will be created to transfer the analysis results to the ABAQUS structural response code. The result is an integrated package that can be used to quickly solve multidisciplinary problems at low cost. BENEFITS: Utilization of the product proposed will reduce the time and cost to develop high-speed missile airframes.
