Responsible Engineers: Emily, Hermanus, Jacky, Cruz, Julianne H.
Previous Research:
Phoenix:Sustainer - Avionics Bay Structures, Booster - Avionics Bay Structures
Hermes III: November 24, 2019 Shake Test, Hermes III Avionics Tower Force Testing, Hermes 3 Reaction Wheel Proposal, Hermes III Payload Bulkhead
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.
- L=\frac{4V}{\pi D^{2}}
- 𝐿=4𝑉/𝜋𝐷^2
(1) V = \frac{w_{parachute}}{\rho_{packing}} - 𝑉=𝑃𝑎𝑟𝑎𝑐ℎ𝑢𝑡𝑒 𝑤𝑒𝑖𝑔ℎ𝑡/𝑃𝑎𝑐𝑘𝑖𝑛𝑔 𝑑𝑒𝑛𝑠𝑖𝑡𝑦
Dual Separation & Dual Deployment
- Approximate diagram of the system with avionics system (not a schematic)
- Switchband system:
- *CO2 canister would be in place of a charge well. CO
- Pomona Liquid Rocket Lab (pg 117+)
- Reinforced, system has a lot of rasberry pis since its for LP, ours will likely be smaller
- Similar to above switchband
- Nosecone bay kits, do we want or need one for GPS?
