Recovery System Calculator

Size your rocket parachute for a safe descent rate. Calculates canopy diameter, area, landing energy, and drift distance using aerodynamic drag equations.

Inputs

Rocket mass (kg)

Target descent rate (m/s)

Launch site altitude (m MSL)

Parachute type (1-3)

Tab to move between fields

Results

Parachute diameter (cm)

52.1

Parachute diameter (in)20.5

Canopy area (m²)0.21

Landing kinetic energy (J)6.25

Descent time (s)0

Wind drift estimate (m)0

How to Use This Calculator

Enter Rocket mass (kg), Target descent rate (m/s), and Launch site altitude (m MSL).
Set Parachute type (1-3).
Review the Parachute diameter (cm) result.
Use Parachute diameter (in) and Canopy area (m²) to inform your decision.
