Webbing lengths must be selected carefully to satisfy several constraints such that parachutes enter the airstream (and do not remain confined within the vehicle). For Project Hermes, the webbing constraints and resulting calculations are summarized below:
For the Hermes Pathfinder vehicle, the relevant dimensions are:
| Section | Length (in inches) | Description |
|---|---|---|
| hmp | 51.3 | Total height of mission package |
| lmp | ||
