Significant Progress!
•
Open Door Flights have been highly successful
– 100% Open Door Flight completed; December 18, 2009
• The Upper Rigid Door (URD) was opened incrementally to 100% of the
Aperture opening, exposing the Cavity to the atmosphere for initial internal
airflow and acoustics characterization tests
• Initial observations of the characteristics of the aircraft with the URD open
up to 100% were benign, with no acoustics or aircraft handling issues
•
Two Door Closed flights completed; January 14-15, 2010
– TA Activation flights successfully completed
– Aircraft Functional Check Flight (FCF), clean-up flight
•
Envelope Expansion flight series started with the 23o (lowest) Aperture position on
January 29, 2010 and completed Feb 11
– 10%, 40%, 70% and 100% Door Open flight envelope expansion at low
altitudes / low speeds nearly completed
(Watch Flight Test Video)
•
Landing with door open at 40% completed!

Challenges
•
Actual Schedules have taken longer than planned
– Analyzing actual data to adjust plans
• Recent schedule performance has taken about 1.4 times longer than 70% JCL
– Flight test objectives have been successful, but taking longer than anticipated
• Weather
• Additional flights
• Cavity Door Drive (CDDS) anomaly
•
Dryden evaluating ideas to shorten path to ISF
– Addition of staff needed to shorten Mission Systems installations and checkout
– More co-location at the DAOF along with key test assets
– Parallelizing appropriate serial tasks
– Scrubbing flight test matrix / approach
•
Program working mitigation approaches for longer-term schedule
– Established a separate Segment 3 planning and schedule development team
– Evaluating several shorter downtimes vs. 1 extended downtime in Segment 3

SOFIA Science/New Instrument Workshop
–
–
Scheduled June 6-8, 2010, Asilomar Conference Center, Pacific Grove, CA
11 invited speakers (confirmed) who are theorists and/or observational astronomers. Instrumentation presentations
to be given by poster only to provide for a level playing field during the proposal evaluations.
–
Electronic registration form has gone live as of today.
Pipeline status:
–
–
Coordinating site visits to some of the major NASA observatory science centers to discuss “best practices and
lessons learned” with the associated pipeline managers.
These discussions should aid in developing the SOFIA pipeline process.

Near-term Program Challenges
• Simultaneously conduct flight testing, SI integration and test, and
accomplish re-baseline activity
– Schedule
• Establish a realize-able risk-adjusted schedule
– Center near-term recovery effort
– More timely and accurate schedule planning
– Implementing EVM and re-running JCL
• IMS re-structuring
• Update threat integration
• Update resources
– Conducting flights in a safe and efficient manner
21
Program Summary
•
Program completed 10% door open flight and 100% door open flight prior to end of 2009
calendar year
– Highly successful with no acoustic or aircraft handling issues
– Mission Systems operating well
•
Program accomplished the TA activation and started Open Door Envelope Expansion flights
– Successfully completed door open at 40% landing
•
FORCAST arrived at the DAOF, February 8, 2010
•
Program is working with Dryden Center Management to achieve longer-term schedule
commitments to Initiation of Science (ISF)
•
Program considering adding a JCL threat that accounts for the schedule continually being
under-planned and increasing the maximum schedule impact of the flight test threat
•
Program is in close coordination / contact with DLR and monitoring FIFI-LS funding situation
•
Expecting EVM / JCL runs with re-structured IMS in early-March to support the SRB and the
Agency re-baseline
•
Program considering changing Limited operating capability (LOC) milestone to Initial
Operating Capability (IOC)
