- After the CoDR, it was decided that a physical connection must not be present between both stages.
- The guide will stop the sustainer from rotating unnecessarily and removes the need for shear pins to connect both stages which reduces spring constant requirements.
- A tight tolerance with low friction is required.
Final Design - V1:
- Use Nichrome in tension instead of Dyneema.
- Only a single piece of Nichrome is used to hold the springs in compression. From initial calculations, 2 mm gauge Nichrome was enough due to the high tensile strength of Nichrome.
- Nichrome can be wrapped around the bushing at the top of the interior of the staging cone below the screw for attaching the shock cord.
