RockOn! Canister Integration RockOn! 2009

2 Overview: -Now that your payload has been built, tested, and mounted to a structural plate, it is time to assemble a stack of plates and integrate them into the RockSat canister configuration. -This procedure has changed a bit from last year -Not all pictures have been updated

RockOn! What Are We Building? RockOn! 2009

4 Final Product 1: Above: 5 plate stacked configuration. Below: Stacked configuration in can. (Minus lid)

RockOn! Final Product 2: SolidWorks model and actual picture of structural RockSat canister. 5 Plate Stack Stand-offs attached to Top Lid. Barrel Section attached to Top Lid (8 Places) Assembled can with payload ~20 pounds

RockOn! Groups and Hardware RockOn! 2009

7 Group Formation: To Begin: - Examine your plate for a serial number. The leading number indicates which can your team flies in, and the last two digits indicate plate number. Can Number Plate Number

RockOn! Group Formation 2: -Find the other four (4) groups that have the same can number and sit together. (5 Plates total) -The assistants will come around and pass out the hardware that each team will need to build the RockSat can structure.

RockOn! An Update RockOn! 2009

14 Update Note: -Some AVR boards were too close to a support stand-off during fit checks.

RockOn! Update Note: -To help alleviate the issue, a small chunk was nipped from the edge of the board. -This should resolve the issue. -If at any time you are unsure if you may be doing damage to your board while installing stand-offs, please raise your hand.

RockOn! Crowd Control RockOn! 2009

17 Crowd Control: -Listen to your integration table leaders -Don’t crowd the table -Respect the payloads above and below your payload -Take your time because there is no time fix your mistakes -Watch out for wires and the handling of the wires -DO NOT WORK AHEAD -Pay attention to overall announcements -Listen to your integration table leaders, they are responsible for your successful integration

RockOn! Bottom Bulkhead 1: -Carefully turn the stack upside down. -Place the bottom bulkhead (with the outer bolt circle) on the bottom of the stack -Make sure the notch aligns with the set of blue RBF wires as shown.

RockOn! Bottom Bulkhead 2: -Take one (1) 1/2” bolt and locking washer and hand screw it into the center stand-off as shown.

RockOn! Bottom Bulkhead 2: -Lightly tighten the 1/2” bolt and lock washer with the hex key. -Important: Don’t not over tighten the bolt. After all bolts are in, they will be torqued to 30 in*lbs.

RockOn! Bottom Bulkhead 3: -Insert and tighten the remaining four (4) 1/2” bolts and washers on the bottom bulkhead. -Note: Add the bolts in an alternating fashion (like tire lug nuts) as indicated above. Tighten until bolts are flush with the plate

RockOn! Outer Skin 1: -Ensure that the blue wires all pass down the channel with the LEDs. -Also check that no wires or objects are on the edge of any of the plate. -Place the outer skin onto the bottom bulkhead.

RockOn! Outer Skin 2: -Align the outer skin to allow the skin and bulkhead holes to line up. -By hand, screw in all eight (8) 3/8” bolts through the skin to attach it to the bottom bulkhead. Good Alignment -Important: Do not over tighten the bolts. The bolts will be torqued to 30 in*lbs 8 Total

RockOn! Outer Skin 3: -Use the hex key to lightly tighten all eight (8) 3/8 bolts -Note: Use an alternating pattern (like tire lug nuts). -Caution: Do not over tighten the bolts. The bolts will be torqued to 30 in*lbs once all structural bolts are installed.

RockOn! Outer Skin 4: -Your structure should now resemble the picture to the left.

RockOn! Outer Skin 5: -Place the top bulkhead on the stack as shown to the left. -Make sure that the notch aligns with the wire path way.

RockOn! Outer Skin 6: -Align the outer skin to allow the skin and bulkhead holes to align. -By hand, screw in all eight (8) 3/8” bolts into the skin to attach it to the top bulkhead. Good Alignment 8 Total

RockOn! Outer Skin 7: -Use the hex key to lightly tighten all eight (8) 3/8 bolts -Note: Use an alternating pattern (like tire lug nuts). -Caution: Do not over tighten the bolts. The bolts will be torqued to 30 in*lbs once all structural bolts are installed.

RockOn! Outer Skin 8: -Your structure should now resemble the picture to the left.

RockOn! Top Bulk Head 1: -You might find that your top bulkhead bolts don’t align perfectly. -If this is the case, reach in through a window and apply a small amount of force to achieve alignment.

RockOn! Top Bulkhead 2: -Once alignment is achieved, insert one (1) 5/8” bolt and lock washer into the center hole. -Lightly tighten the bolt with the hex key. -Important: Leave this bolt loose enough to make slight adjustments to the other four (4) bolts.

RockOn! Top Bulkhead 3: -By hand, lightly screw in the other four (4) 5/8” bolts and lock washers.

RockOn! Top Bulkhead 4: -Use your hex key to tighten all five (5) 5/8” bolts and lock washers on the top of the bulkhead.

RockOn! Top Bulkhead 5: -Your structure should look like this, but with more wires coming down the pass-through. -Note: All LEDs and connectors should be visible in the wire way.

RockOn! Final Product: Congratulations! You have completed integration of your payload with the RockSat can. We will now walk through a shorting plug test, pull the RDY LED, and get all structural bolts torqued and ready for the hand-off to Wallops engineers!
