Hermes Quicklink and Swivel Analysis: Hermes Quicklinks & Swivels
Separation Type
Single Separation & Dual Deployment
- Dohttps://wiki.rit.edu/pages/viewpage.action?pageId=229713880ne on Hermes, Staging Demo Sustainer and Phoenix Sustainer
- Combined drogue & main bay takes up less space in mpt
- 1 separation system isn't as heavy
- Would have to use TDs or cable cutters
- TDs may not work at high altitude (issues w/ heat transfer and combustion in low pressure)
- May be good to test TDs in vacuum chamber at lower pressure
- Use a cable cutter?
- https://aeroconsystems.com/cart/launch-recovery/cable-cutter-by-archetype-rocketry/
- Still uses bp so might not work at high altitude but could have better pressure seal
Dual Separation & Dual Deployment
- Heavier (two separation systems vs one) and takes up more space
- No reliance on TDs
- Don't have to worry about main tangling while drogue is deployed

Failure Modes
- Webbing failure modes: Hermes Webbing Failure
- LINE TANGLING!!!!
- TD failures
- e-match shorting
- wet black powder or TD isn't pressure sealed so black powder can't combust
