April 8, 2005 ANITA Collaboration Meeting/UCI/Marc Rosen 1 GONDOLA DESIGN & ANALYSIS OFFENDING OVERHANG/UNDERHANG CORRECTED ALL ANTENNAS NOW PLACED IN EITHER ONE OF TWO PHI POSITIONS FRAME DESIGN AT A COMPONENT LEVEL IS IN PROGRESS (CAD MODEL) GONDOLA DESIGN & ANALYSIS REPORT NEED TO BE SUBMITTED ~60 DAYS PRIOR TO EM FLIGHT FOR CERTIFICATION ROSEN AND MACNEAL HAVE COMMUNICATED ON THIS, RECOMMEND OVERSIGHT BY LIEWER (JPL TO SUBMIT REPORT) SOLAR POWER NEEDS ATTENTION, BUT IS NOT RQD FOR EM FLIGHT WHAT ARE WE GOING TO FLY ON THE EM FLIGHT???????????

April 8, 2005 ANITA Collaboration Meeting/UCI/Marc Rosen 2 GONDOLA DESIGN & ANALYSIS THE FIX TO THIS IS TO MAKE THE BOTTOM OCTAGONAL PROFILE OF THE TOP RING IDENTICAL TO THE TOP OCTAGONAL PROFILE OF THE LOWER RING. THIS DISTRIBUTES THE UPPER AND LOWER CORNER OBSTRUCTION EQUALLY BETWEEN THESE TWO RINGS. NEW GEOMETRY WILL BE DEMONSTRATED IN CAD. IT HAS DIRECT IMPACT ON THE LAUNCH ENVELOPE POSITION, AND MOST IMPORTANTLY THE PV ARRAY.

April 8, 2005 ANITA Collaboration Meeting/UCI/Marc Rosen 3 GONDOLA DESIGN & ANALYSIS PHI ALIGNMENT: ALL ANTENNAS ALIGN WITH EITHER A FLAT OR A VERTEX OF OUR OCTAGANAL COLUMN (16 HORN RING WAS FORMERLY MISALIGNED BY 11.25deg)

April 8, 2005 ANITA Collaboration Meeting/UCI/Marc Rosen 11 GONDOLA DESIGN & ANALYSIS BRIEF SUMMARY OF PHOTOVOLTAIC ISSUES NEW SUNPOWER CELL REPLACES OLD SHELL CELL (~13 -> 20% EFFICIENCY) PSL IS ADAPTING CHARGE CONTROLLER TO NEW CELLS WASH U IS WORKING WITH SAME CC AS PSL ANITA PLANS TO DEVELOP CARBON FIBER PV PANEL FRAMES I EXPECT TO LEARN MORE NEXT WEEK IN PALESTINE

April 8, 2005 ANITA Collaboration Meeting/UCI/Marc Rosen 12 GONDOLA DESIGN & ANALYSIS THE EM FLIGHT NEED TO MOVE FORWARD WITH AGGRESSIVE SCHEDULE FRAME = BEST EFFORT, BUT NOT NECESSARILY PERFECT BE PREPARED FOR UNIQUE ASSEMBLY (MATCH DRILL IF NEEDED) WE WILL LEARN A LOT FROM THIS FIRST EXERCISE EM FLIGHT IS PRIMARILY TO DEMONSTRATE LAUNCHABILITY AND STRUCTURAL INTEGRITY WHAT ARE WE GOING TO FLY???????????
