  • Connecting loops (3)
  • Black Powder
  • Gloves
  • Popsicle sticks and weigh boats
  • Goggles
  • Paper funnel

Procedures

  1. Attach integrated piston to payload bulkhead with ¼-28 bolts, ensuring the bolts are very tight! The clocking matters, clocking mark to be added

  2. Attach the integrated AV tower to payload bulkhead with 6-32 bolts. The elbow/ tee fitting assembly must be turned slightly inward in order to fit the AV Tower on top.

  3. Wire piston to AV tower

  4. Attach recovery guard to piston using ¼-28 bolts and washers 

     

  5. Integrate soft goods and tender descenders 

    1. The TD loops have 2 distinct sides:

      1. longer side has 5 things:
        1. main loop 1
        2. locking loop
        3. main loop 2
        4. load bearing riser
        5. the QL to main riser
      2. shorter side has 1 thing
        1. QL to eyebolt *attach the TD retention loops to the QL

    2. Another QL at end of MP Riser to Motor Section Riser (wide Black) and Main Riser (Blue Spectra)

    3. Main Bag Bridles and load-bearing riser to QL to black Drogue Swivel to drogue riser

    4. Drogue riser to QL to drogue lines

    5. Connect bottom of drogue bag to Motor Riser inside swivel

    6. Connect Motor Riser to loop to swivel to loop to eyebolt

    7. For tender descenders from Main Bag TD loops to eyebolt:

      1. Wear goggles and gloves to measure appropriate black powder using weigh boats, scale, and popsicle sticks

      2. Hold TD loops in place, pushing towards center to ensure the loops don't get caught. Check that the loops slide freely.

      3. Use funnel to fill TD with black powder

      4. Push the two pieces of TD together

      5. Repeat with second one

      6. Connect TDs to Main bag: TD loop through 2 main loops, load bearing riser, and locking loop (check it is through all 4!)

      7. Connect white 1500lb swivel, TD loops, and TD restraining loops (thin yellow) to QL. Attach QL to eyebolt.


  6. Tighten all quick links with a wrench

  7. Screw antirotation rod into diaphragm with locknut. Screw on skinny god nut all the way down and add a washer. Place diaphragm on. 

  8. Next, hold the god nut with small pliers and screw the eye nut tight. Insert cotter pin. Fold down legs and stick gaff tape over the spikey bits of the cotterpin!

  9. Pull up on diaphragm and use wrench to tighten nut upwards until fully tightened.

  10. Set up integration stands. Stand piston-diaphragm assembly and cup close to each other.Thread main bag with lines and tender descenders through cup, so tender descenders are close to the diaphragm. Pull tender descender wires through half-moon shaped hole and attach tender descenders to eye nut.

  11. Push cup (with main bag, TDs and lines) onto diaphragm and secure with 10-32 grub screws. To line up, use higher holes on diaphragm and clocking mark on cup.

  12. Attach swivel (on motor riser) to quick link on top of main bag

  13. Quick link drogue to drogue riser

  14. Slide mission package tube over all components

  15. Push in shear pins and cover with tabs of gaff tape

  16. Screw in nosecone coupler to the MP tube and payload bulkhead with 10-32 flatheads with a 100 degree chamfer. Don't screw in bolts all the way until all 3 of them are in.

  17. Attach nosecone and nosecone tip
