Parachute design calculations
WebSep 4, 2004 · Cd= the coefficient of drag of the parachute – estimated to be 0.75 for a round canopy V = the descent velocity of the rocket, 11 to 14 ft/s (3.35 m/s to 4.26 m/s) being considered a safe descent speed. With this descent rate equation, and a good calculator, one can readily find the needed minimum parachute area for a particular model or mission. WebThis calculator is based on the original EMRR calculator by Jordan Hiller. Enter the weight of your rocket (don't forget to include the weight of the expended motor). Then enter the diameter (or maximum width) and choose the approximate shape of the parachute. Optionally, enter the altitude at which you expect the parachute to deploy.

WebFeb 3, 2024 · Shredding of the Drogue. We can probably do a small calculation to determine the approximate forces that the rocket will experience due to the deployment of the main parachute. F = ma. m = 8kg. a = Delta V/ Delta T. Delta V = 6 – 22 = -16ms-1. Delta T = 0.25 seconds (BIG GUESS) WebYou are a team of engineers who have been given the challenge to design a parachute out of everyday items. Your challenge is to design a parachute that will hang in the air the longest. (30 minutes) I. Planning Stage 1. Meet as a team and discuss the problem you need to solve. Then develop and agree on a design for your parachute.
