Model Rocketry Parachute Size Calculator

For a given rocket mass give the required parachute size needed to achieve a specifed ground impact speed

      Drag Coefficient of the chute  Cd =  .

      Desired Speed of impact v =  m/s

      Mass of rocket M =  kg

      Acceleration of gravity g = 9.8 m/s/s

      Density of Air p = 1.22 kg/m3

      Diameter of parachute D = 0.00m or 0.00cm or 0.00 inches. 

  

Requried Parachute Diameter is: 0.00 m or 0.00cm or 0.00 inches.
