Overview
This parachute is deployed near apogee to enable a rapid, controlled descent in compliance with section 3.1.1 of the DTEG.
Analysis
- The black, dark blue, and blue sets of lines represent the different vehicle weights (157, 167, and 177 lbs)
- The different lines within those sets represent the different launch angles
- These sets of lines follow the ascent and descent without parachute
- The light blue steady state descent lines represent descent with parachute
