IGF::OT::IGF ADVANCED COMBUSTION VIA MICROGRAVITY EXPERIMENT (ACME) IS A CHAMBER INSERT ASSEMBLY (CIA) DESIGNED TO OPERATE AS A SUB-RACK PAYLOAD IN THE NASA INTERNATIONAL SPACE STATION (ISS) COMBUSTION INTEGRATED RACK (CIR) FROM SEPTEMBER 2017 (ISS INCREMENT 53) THROUGH JULY 2020 (ISS INCREMENT 64). THE INSERT WILL FUNCTION AS AN EXPERIMENT PLATFORM FOR 5 GASEOUS FLOW COMBUSTION EXPERIMENTS (CLD FLAME, E-FIELD FLAMES, BRE, S-FLAME, AND FLAME DESIGN). . THE PURPOSE OF THIS WORK EFFORT IS TO SUPPORT THE CIR OPERATIONS PLANNING AND PROCEDURE DEVELOPMENT FOR EACH OF THE 5 EXPERIMENTS AND TO OPERATE THE INSERT DURING TEST POINT OPERATIONS. THE EFFORT WILL INVOLVE PERIODIC MEETINGS WITH THE ACME SCIENCE TEAM IN ORDER TO UNDERSTAND NEAR TERM SCIENCE OBJECTIVES AND TO DEVELOP A PLAN FOR OPTIMIZING THE SYSTEM CONFIGURATION TO MEET THOSE OBJECTIVES. ADDITIONALLY, THIS EFFORT WILL BE RESPONSIBLE FOR ADVISING THE FACILITY TEAMS ON CONSUMABLES EXPENDITURES, GROUND DISPLAY NEEDS, AND NEEDED SPARES. THIS STATEMENT OF WORK (SOW) ALSO INCLUDES THE DELIVERY OF FLIGHT HARDWARE THAT HAS BEEN IDENTIFIED AS CRITICAL FLIGHT SPARES FOR SCIENCE. THE EFFORT INCLUDES BUILDING TWO (2) 14-MICRON THIN FIBER PYROMETRY ARRAYS AND TEN (10) IGNITER TIP ASSEMBLIES.
