Announcements

Subsystem Discussion

Picosat Launcher Engineering Model -- Jeff

• Order rect. and Belleville springs, latch cables -- waiting to hear back from Richard Anderson about possibility of his machinist producing the springs. (10-27 -- heard from Richard, he is unable to produce springs)

Jeff to order Belleville springs
Andy to purchase cables and suager
• Fabrication quote and production -- in purchasing now, should be processed by 10/28 and go to the shop.  Jeff to check with Carolyn to make sure, should have delivery date this week
• Dry lube application -- Eric to contact Dicronite people to find out what we need to do to get in.  Also look into use of teflon tapes
• Instrumentation -- we have everything needed for the EM instrumentation except a magnet to use witht the Hall effect sensor.  Instrumentation need to be put together before we get the EM back
• Actuators -- received actuators this week
• Launch sequence -- no update
• Test apparatus -- decided to place EM in OPAL structure to shake it
• Testing procedures -- will be integrated into OPAL structure shake test procedures
• Need to get list of  machining needs to Santiago -- we will need front stops, picosats, actuator brackets, cable guides, and hinge pins.  Put bored out hole in one picosat to mount actuators for testing
• Need to check on availability of pico teams' mass models

Launch Interface -- David

• Task list
• Actuator redesign and method of attaching OPAL -- Jin working on this
• Part fabrication -- Santiago has it assigned, but needs details on what is needed;  David to order cup/cones this week
• Shake interface with OPAL vertically 
• Structural analysis -- Eric to write this up this week for documentation
• Test apparatus -- David to check on specifics from LM  
• Production drawings -- Eric to start on production drawings for flight interface

Structure -- Santiago

• Machining coordination -- need details for machining
• Shake structure:
• Mass boxes -- almost finished
• Assemble shake structure
• Static loads test  -- need to start looking at how to go about doing this.  
• Flight structure:
• Parts to send to WSU for mass model

Testing -- David and Andy

• Interface and OPAL structure verification testing -- David to contact LM tomorrow for update on date availibility 
• Launcher EM testing -- to be combined with OPAL structure test
• Testing procedures -- integrate EM procedure into structure procedure, fax over to LM early next week after we get more specific load info from JAWSAT CDR this week

JAWSAT and Orbital Sciences Corp. -- Jeff

• Interface Control Document updates 
• JAWSAT CDR & PIWG Oct. 29 at Weber St. 
• OPAL mass model Nov. 30 -- need to find out more specific requirements for mass model at CDR
• Battery trickle charger through ASU -- Carlos GS taking this over for coordination with ASU
