- Calculating yield strength in a thread/maximum load on a thread & cases with screw on forward closures - Alex My name jeff
- Screwed on forward closure done for small rockets
- Pretty viable
- Big tap/chonky threads
- Work with Cruz to figure out 3d experience - Aimee
- No emails yet
- Grabcad for now
- How thick does case need to be to reach pressure - Elizabeth
- Did calculations on case thickness
- Borderline on thin vs thick case so using both equations
- Choose the one that gives thicker case
- Around 2 inches OD
- Reach out to Kelly - Elizabeth
- Found yellow tubes on Mcmaster
- Need to find one that fits with the casting tube
- Find casting tube that fits in liner
- Integrated forward closure case design - Justin
- Used liner type that is same size as Kelly
- has been updated to remove steel ring
- Can do no forward closure design with tube machined in
- Bolt calcs
- Liner needs to be cut to size
- installation disk on one side
- End burner w/cylinder propellant for constant burn rate
- Air could get compressed
- Have steel bolt on bottom for venting
- Used liner type that is same size as Kelly
- Test stand - Aimee & Tamara
- Three prts
- Base plate
- weld to ring holding motor
- use aluminum plate to be able to weld
- Motor case
- Thick ring to hold motor
- hole in bottom
- Machine out half an inch to make a nub and thread it to screw on
- radial bolts that interface w motor
- if bottom fails what happens to top?
- have another ring on top that surround motor case
- top layer holding onto top of case
- hole in the center
- keep in place w/ eye bolts and ratchet straps
- Base plate
- Three prts
- Other
- 3 propellant formulas
- Boron
- 10 characterization fires
- 3 propellant formulas
- New Assignments
