Requirements
The following are relevant propulsion requirements defined by the Spaceport America Cup DTEG. Team-defined requirements for specific components may be found on their respective pages.
| Requirement | Description |
|---|---|
| 5.3 | Launch vehicles entered in the SA Cup shall use non-toxic propellants. Ammonium perchlorate composite propellant (APCP) is considered non-toxic |
| 5.5 | Metallic cases and forward closures shall be made of non-ferrous ductile metals such as 6061 aluminum alloy |
| 5.7.1 | All teams shall use either of the following for launch: Two (2) independent motor igniter devices OR One (1) pre-wired igniter containing two (2) ignitor heads |
| 5.17.5.1 | SRAD propulsion systems shall successfully complete an instrumented (chamber pressure and thrust), full scale (including system working time) static hot-fire test prior to the SA Cup |
| 5.18.2 | The minimum thrust-to-weight ratio for all competition launches shall be 5:1 |
| 6.19.4.1 | All SRAD and modified COTS pressure vessels constructed entirely from isotropic materials (e.g., metals) shall be designed to a burst pressure no less than 2x the maximum expected operating pressure |
| 6.19.6.1 | All SRAD pressure vessels shall be proof pressure tested successfully to 1.5x the maximum expected operating pressure for no less than twice the maximum expected system working time |
| 10.2.1 | A rail departure velocity of at least 100 ft/s is required |
