OPAL Action Item Summary 

Testing 

• Need to define the standards that we are testing to, have written test plans, and give that info to OSSS (copy of mil-std 1540c provided as example)
• Their high fidelity shake is going to be 12/7 – we should get our mass model back by 1/1 barring any unforeseen delays
• Need to provide OSSS with evidence of 1) structural integrity, 2) mechanical reliability of sep system, 3) electrical compatibility through ICD
• Paul Wilke from CSA wants to come to shake tests and get data to verify their FEA
• OSC  -- vibe profile will be essentially the same as in rev. 2 of the user's manual, with the addition of an approximate 14.7g transient load at 1st stage ignition
• CSA will be running vibe tests on the softride system in March and will need our mass model again

• holes toleranced to 5 mils positional tolerance from side datums
• must use mechanically locking #10-32 UNF grade 8 or higher thru bolts (bolts through from payload side)
• JAWSAT side of DB-9 connector will be bolted parallel to face of JAWSAT frame – we need to pigtail to it
• OSC fourth stage will provide nominal 28V signals to us – we will have to condition it for our uses
• need to possibly use multiple bolts to bolt to isogrid – concern of tearing off isogrid
• OSC desires lowest possible separation velocity (other payloads ~.5 ft/s)
• separation confirmation switch should be  5V
• send separation specs (mass, sep velocity, impulse duration) to OSC by 11/15

• Need to rewrite schedule to include margin, post to ftp site, send to Buckley
• provide mass model by 11/30 – mass model needs to be at least first order (correct mass, cg, connection points)
• need to get FCC frequency allocation, send copy of FCC application to Buckley
• need to give list of those going to 12/2 PIWG at Vandenberg to Buckley for visitor passes
• if we want a turn-on contingency, we have to prove to OSSS and Buckley that we will do absolutely no harm to other payloads (including EMI, which will be a problem for MSFC payload)
• OPAL can not turn on until at 30 minutes after separation
• imperative that all payloads separate – endangers rest of mission if don't release (Buckley: “When we tell you to leave, get the hell out of Dodge.”)
• ASU to specify type of connectors for trickle charge

• need to specify OPAL handling constraints
• determine what kinds of checks to do after integration acceptance testing and shipping
• review ICD matrix, fill in blanks
• include interface info in ICD (sep velocity, time duration, OPAL mass)

• we can port to OPAL after integration test to verify operation
• modal sweep data and static stress analysis for JAWSAT in presentation handout 
• JAWSAT is thermal cycling from -20C to 60C
• ASU trickle charger will have a total cost of around $2000, split cost among all using it
