Sub-assemblies

  1. Motor


  2. Piston


    Materials

     

    • 1/4 in torque wrench

    • Integrated Firebolt
    • Multimeter
    • Teflon tape
    • 1/4 NPT plug 
    • Safety goggles
    • Gloves
    • Scale
    • Weigh boats 
    • Popsicle sticks
    • Elbow joint
    • Tee fitting
    • Adjustable wrench
    • Vice grip/pliers
    • Plug

    Procedures

    1. Using a 1/4 inch torque wrench, ensure that the bolts holding the piston together are very very tight. If the bolts are loose, the piston will lose pressure as it extends.

    2. Use multimeter to check continuity of Firebolt (should be about 1.0-1.4 ohms) and twist the wires to short it. Two people should visually confirm that it is shorted. Wrap the Firebolt with five wraps of Teflon tape. Use pliers to screw firebolt into the NPT plug.

    3. Everyone put on safety glasses. From now on, everyone within the vicinity of the pyrotechnics must wear safety glasses.

    4. Measure out the appropriate amount of black powder into a weigh boat (will vary over testing matrix) and pour it into the other side of the tee fitting, holding over a weigh boat. Seal the opening by wrapping over the head and opening three times with Teflon tape.

    5. Compress the piston completely!

    6. Screw an elbow joint into a side female end of the tee.

    7. Wrench the elbow and tee assembly into the inlet hole of the piston with 5 wraps of Teflon tape until extremely tight and turned upright.

    8. Screw a 1/4 NPT plug into a female end of a 1/4 NPT tee adapter.

    9. Seal the open female end of the tee fitting with another plug (filled with appropriate black powder).

       


  3. Payload - NC


  4. AV Tower

  5. Soft Goods


  6. Mystery Box


  7. MP Assembly

    Hermes II Mission Package Assemblage Procedures

Integration Order

Ideally, the piston, AV tower, and payload stack can be assembled in parallel and then each attached to the payload bulkhead. In parallel to this assemblage, the nosecone and mystery box can be integrated. Then the two groups would be integrated together with the soft goods and the fin can.
