Hermes III: November 24, 2019 Shake Test, Hermes III Avionics Tower Force Testing, Hermes 3 Reaction Wheel Proposal, Hermes III Payload Bulkhead
...
Notes (2/19/23):
Look into commercial vibrational testers - Claire
Screw terminal loose – was this the cause of avionics turning on? → Talk to avionics
Look into reviews of screw switches - Richard
https://www.rocketryforum.com/threads/the-avionics-bay-thread-post-your-photos.156649/
Talk to Avionics about required components for upper and lower avionics towers - Emily
Calculate space above AV tower needed to store parachute - Julianne
Look at and dimension Phoenix booster mission package tube
4 components: parachute area for 1st stage, AV bay, parachute area for 2nd, motor
Start CADing slider AV tower
Researc extra forces on AV tower from parachutes, potential buckling
Timeline:
1st meeting points:
How many avionics towers, what does the deployment look like (probably won't be decided) *Assigned
Approximate dimensioning, looking into what the mass would be for these systems assuming Phoenix Avionics systems weights and lengths *Assigned
Sustainer:
Weight:
Length:
Booster
Weight:
Length:
*Need an estimate of board size from avionics
Issue of the bay turning on in transit:
Did the vibration of the system cause the screw to move? If so, we may need better screw switches. This one was highly reviewed by rocketry forum: https://www.csrocketry.com/electronics/missleworks.html
*I need someone to come up with the test and give me commercial vibrational testers
- Incorporating a window for easy access
- *Calculations for bay sizing
- packing volume of the lines and prevent potential line entanglement issues.
