NASA LANGLEY RESEARCH CENTER WILL BE PARTICIPATING IN UP COMING PROJECTS THAT WILL REQUIRE THE 8-FT HIGH TEMPERATURE TUNNEL TO TEST LARGE SCALE PROPULSION GROUND TEST ARTICLES AND FLIGHT VEHICLES. IN PREPARATION FOR THESE PROJECTS THE FACILITY NEEDS TO DETERMINE THE FEASIBILITY OF ACCOMMODATING LARGE SCALE TEST ARTICLES, INTEGRATION AND FACILITY OPERATIONS/INTERACTIONS, AT CONDITIONS THAT ARE CURRENTLY OUT OF THE FACILITIES CAPABILITIES. THE OBJECTIVES OF THIS TASK ORDER ARE TO RESOLVE GROUND TESTING ISSUES RELATED TO THESE LARGE SCALE TEST ARTICLES USING A BLOCKAGE MODEL AND DEVELOP TEST CAPABILITIES REQUIRED TO MEET PROGRAM REQUIREMENTS. IN ORDER TO ACHIEVE THE TEST CAPABILITIES THE FACILITY WILL REQUIRE A NEW MACH 4 AND MACH 6 NOZZLE. THESE NEW NOZZLES WILL BE AN INTERAGRAL PART OF THE 8-FT HTT AT NASA LANGLEY RESEARCH CENTER. THE NEW NOZZLES WILL PROVIDE THE EXISTING FACILITY EXPANDED CAPABILITY REQUIRED TO MEET THE TESTING GOALS OF TEST PROGRAMS PRESENT AND FUTURE. LARGE SCALE TEST ARTICLES POSE ISSUES WITH ACCURATELY DETERMINING BLOCKAGE EFFECTS DUE TO THEIR COMPLEX SHAPES AND THE RESULTING COMPLEX FLOW INTERACTIONS BETWEEN THE LARGE SCALE TEST ARTICLE AND THE FACILITY. A BLOCKAGE MODEL WILL HELP RESOLVE MOST OF THESE ISSUES IN PREPARATION FOR GROUND TESTING LARGE SCALE TEST ARTICLES. THE PURPOSE OF THIS TASK ORDER IS TO OBTAIN THE DESIGNS, ANALYSIS, MANUFACTURING SCHEDULES AND ESTIMATES OF LONG LEAD ITEMS FOR A NEW MACH 4 AND NEW MACH 6 NOZZLES AS WELL A TRADE STUDY FOR A LARGE SCALE BLOCKAGE MODEL. THIS TASK ORDER IS BROKEN UP INTO 3 MAIN SECTIONS: MACH 4 NOZZLE (DESIGN & ANALYSIS), MACH 6 NOZZLE (DESIGN & ANALYSIS) AND A BLOCKAGE MODEL (TRADE STUDY). EACH HAVE SPECIFIC REQUIREMENTS AND HAVE SPECIFIC DUE DATES.
