4 January 17, 2013 ACME Schedule 4

5 January 17, 2013 ACME Status Project Manager: Mark Hickman  Status  Variances ZIN costing is low per Phasing Plan; early impact of low staffing ripples through schedule; purchasing lead time longer due to new ZIN processes; efforts underway to bring schedule to left. CostScheduleTechnicalMgmt. Jan 2013YGGG Oct 2012YGGG WBS Key Issue/ConcernPotential ImpactAction PlanResolution Date Data transfer rates from IPSU to IOP too slow for data files May reduce obtainable science or extend on-orbit time to years Request FCF Sustaining Engineering to investigate methods of improving data transfer rates Request made to FCF Mgr. for inclusion in DO-101 Sustaining Engineering SOW; full resolution likely in FY11. Ops changes by FCF have improved average transfer rates from 0.9 MB/s to 1.15 MB/s, a 20% improvement. Improvement to 1.80 MB/sec not realized as IOP-HP upgrade implementation results in rack lock-up. Sustaining Engineering looking into possibility of replacing IPSUs. Getting BRE up to speed quickly enough that the design is not negatively impacted May have to do some redesign to ACME Working with BRE PS to get requirements in as early as possible. RDR/PDR (Go/No Go Gate), March

9 January 17, 2013 Project Manager’s Top Challenges 1.Integration of BRE into ACME (BRE SCR indicates that integration is highly feasible) 2.Insufficient on-orbit transfer rates to quickly telemeter data to ground (performed telemetry analysis to determine data volume and rates—rates still determined to be insufficient; IPSU replacement now DO-101 task) 3.Large number of Test Points to accomplish over mission life—approximately 250 primary test points for 5 experiments; however, PI’s would like more than 50 test points each 4.ZIN Vendor/subcontractor delivery process slower than expected; ZIN to address through their company WBS Prosilica Camera, Color Camera Package (outside Chamber) Hitachi Analog Camera, Operations Imaging (inside Chamber) ACME E-Field Grid System

10 January 17, 2013 ACME Risk Assessment (Top 5 Risks) CriticalityL x C Trend High  Increasing (Worsening)  Decreasing (Improving)  Unchanged ( ★ ) New since last month Med Low Approaches: Mitigate, Watch, Accept, Research Last update 09/18/12 Next update 10/16/12 WBS Risk IDRisk TitleRisk StatementLCApproach ACME 021 Mroczka 04/2012 Inability to disassemble Mass Flow Controllers for Conformal Coat / Ruggedizing Given that the Mass Flow Controllers cannot be fully taken apart to perform conformal coating and staking on the electronic boards; then there may be an incompatibility with elements of the chamber atmosphere including fuels, oxygen and diluent mixtures causing CIA electronics to fail. 44 Mitigate: This risk will be re- assessed after reviewing the results of the analysis scheduled to take place by September [ZIN M&P assessing.] Close: Oct 2012 ACME 014 Rogers 12/2010 IPSU to IOP image transfer rate Given that the current data transfer rates from the IPSU to the IOP is severely limited, transfer of ACME data may take an unacceptable amount of time and may reduce obtainable science for the allotted operational time on-board ISS. 53 Mitigate: FCF Sustaining Engineering will investigate methods of improving data transfer rates. ACME requires 10 MB/s. Close: Dec 2013 ACME 010 Mroczka 06/2010 CIA electronics and fuel mixture compatibility Given that the CIA electronics are exposed to chamber atmosphere; then there may be incompatibility with elements of the chamber atmosphere including fuels, oxygen and diluent mixtures causing the cube to fail. 35 Mitigate: Develop a test plan to determine what components and what surface treatments would mitigate this risk. This risk will be re-assessed after reviewing the results of the analysis scheduled to take place by September [ZIN M&P assessing.] Close: Dec 2012 ACME 008 Gobeli 12/2009 E-field emission exceedences Given that there might be emission exceedences; then there is the possibility that the EMI requirement will not be met and ACME hardware would be adversely effected causing diminished science to occur. 23 Mitigate : Test integrated assembly for EMI interference..

12 January 17, ACME Science Report January 2013  Progress in last quarter (nominally Oct.-Dec. 2012) 1.BRE – 40 exploratory 2.2s drop tests with gaseous fuel (CH4 & C2H4) and cup burner. 2.BRE – prototype burner received from PI and preparations initiated for 5.2s testing. 3.E-FIELD Flames – determined that planned power supply is unacceptably slow and verified in 1g that the loaned alternate met response time req’ts, but loaner was +/-5 instead of +/-10kV. 4.E-FIELD Flames – 8 preliminary 2.2s drop tests with +/-5kV high-voltage amplifier. 5.General – entire 2.2s video system upgraded for ACME - but is a new facility capability. 6.General – initial evaluation of flight-like cameras in 2.2s testing (i.e., with 0g flames).  Plans for this quarter (Jan.-March 2013) 1.BRE – 5.2s drop tests with PI-provided prototype burner(s). 2.BRE – procure and evaluate smaller heat flux sensors, e.g., for use with 25-mm burner. 3.BRE – update science requirements in preparation for June RDR. 4.BRE – make initial arrangements for June RDR (e.g., science panel participation). 5.E-FIELD Flames – prepare for 2.2s evaluation of alternate +/-10kV amplifier. 6.General – 2.2s drop test evaluation of flight-like GigE camera for pyrometry. 7.General – 2.2s drop test evaluation of flight-like radiometers and/or PMT modules. 8.General – implement hardware to enable GigE camera evaluation in 5.2s drop tests.  Issues and Concerns (upcoming milestones) 1.BRE - weak/unstable flames observed in some 2.2s drop tests. 2.BRE - potential need for thermal control of burner’s heat flux transducers. 3.BRE - RDR, including go/no-go decision, in June. 4.E-FIELD Flames - unacceptable response time for planned high-voltage power supply. 5.General - science loss for BRE and Flame Design if testing is restricted to 30% oxygen in the chamber.

13 January 17, ACME Grant Status January 2013  All FY13 payments for PI funding have been made FY13 is a skip year for PI funding, where the only PI funding is for Quintiere (U. Maryland). With the exception of Quintiere, all ACME PIs were forward funded since the project’s inception as a unified program (2006), e.g., with FY12 dollars for FY13 work.  PI funding will next be added at the beginning of FY14.  PI funding currently totals $0.5M /year for 5 experiments, i.e., $100k/year/experiment.
