- Notably, the chute used in the study (~15 feet diameter) is much larger than our expected drogue parachute (~4 feet diameter)
- Study chute had geometric porosity ~12.5%
- Fabric: 2.0 oz/yd2 dacron
- Shroud lines: 550-lb coreless braided dacron, 15 ft long
- 5.52 lb mass
For the purpose of a simplified analysis, we examined a range of possible main-deployment dynamic pressures (using the chart featured in the Hermes Disk Gap Band Design page as a basis for our analysis). This analysis also made use of a Standard Atmospheric Model Calculator Tool (without including a temperature offset):
Terminology
geometric porosity: the percent of the nominal canopy surface area that is removed due to vents and gaps
