  1. TRANSITION STUDY GROUP • A PROPOSAL TO RE-FORMULATE THE GROUP AS A WORKING GROUP OF THE AIAA FLUID DYNAMICS TC AIAA FLUID DYNAMICS TC

  2. TSG HISTORY • BASIC REFERENCE: • Eli Reshotko, AIAA J. Vol. 13, No. 3, pp 261-265 (1975). • HISTORY • INITIATED IN 1970 AS THE NASA TRANSITION STUDY GROUP a.k.a. U.S. TRANSITION STUDY GROUP • CONTINUOUSLY CHAIRED BY ELI RESHOTKO 1970-2000 • SUPPORTED OFF-AND-ON BY NASA AND AFOSR • MET INFORMALLY 1994-2000 AIAA FLUID DYNAMICS TC

  3. ORIGINAL OBJECTIVES • “DEVELOP AND IMPLEMENT A PROGRAM THAT WOULD DO SOMETHING CONSTRUCTIVE TOWARD RESOLVING THE MANY OBSERVED ANOMALIES IN BOUNDARY-LAYER TRANSITION DATA …” • FORMULATE SPECIFIC EXPERIMENTAL PROGRAMS • CAREFUL AND REDUNDANT MEASUREMENTS • DOCUMENTATION OF ENVIRONMENT • ELIMINATE FACILITY INDUCED TRANSITION AIAA FLUID DYNAMICS TC

  4. CURRENT MISSION STATEMENT • DISCUSS AND EXCHANGE INFORMATION ON BOUNDARY-LAYER STABILITY AND TRANSITION RESEARCH. • DEVELOP NEW AREAS OF RESEARCH AND DEVELOPMENT. • ASSESS THE COORDINATION AND FOCUS OF SPONSORED RESEARCH EFFORTS. • PLAN AND IMPLEMENT COOPERATIVE ACTIVITIES TO RESOLVE ANOMALIES IN DATA AND BETWEEN DIFFERENT COMPUTATIONS. AIAA FLUID DYNAMICS TC

  5. ORGANIZATION • INITIALLY, THE SCOPE WILL BE LIMITED TO SUPERSONIC AND HYPERSONIC FLOWS SINCE THESE ARE THE PRIMARY PROGRAMS THAT ARE FUNDED IN THE U.S. • MEET TWICE A YEAR: JANUARY (AIAA, RENO) AND JUNE (AIAA FLUID DYNAMICS CONFERENCE). AIAA FLUID DYNAMICS TC

  6. ORGANIZATION CONTINUED 11 MEMBERS WILL SERVE TERMS OF 3 YEARS WITH OTHERS ROTATING IN ON A REGULAR BASIS. THIS GROUP WILL SCHEDULE AGENDA ITEMS, SOLICIT INPUT FROM THE TRANSITION COMMUNITY, WRITE POSITION PAPERS, AND IN GENERAL, CARRY OUT THE MISSION STATEMENT. • THERE ALWAYS WILL BE A SESSION OPEN TO ALL INTERESTED PEOPLE TO DISCUSS PROBLEMS OF TRANSITION AND TO GIVE BRIEF REPORTS ON CURRENT WORK. AIAA FLUID DYNAMICS TC
