Translations:Rocket Parachute Size Calculator/5/en

The desired descent rate depends on your needs. As a rule of thumb, the main parachute should slow the rocket to approximately $$6.1\,m/s\,(20\,f/s)$$ while the drone should allow the parachute to descend much faster $$18.3\,m/s\,(60\,f/s)$$ - $$21.3\,m/s\,(70\,f/s)$$. The editor has presets for these, with the value for the drogue being in the middle of the range. You can set a custom descent rate to suit your needs.
