Parachute-Sizing

Application to calculate the parachute diameter required for a given mass and descent velocity, considering varying air densities at different altitudes.

Requirements

• Python
• Numpy
• Matplotlib
• Tkinter (for interface)

Usage

1. Run the script:

   python interface.py

2. Input Parameters:

   • Minimum Mass (kg): Lower bound of the rocket mass range.
   • Maximum Mass (kg): Upper bound of the rocket mass range.
   • Descent Velocity (m/s): Target descent velocity.
   • Drag Coefficient: Coefficient of drag for the parachute.
   • Altitude (km): Altitude at which target descent velocity should be reached (air density is calculated here).

3. Update Plot:

   • Click the Update Plot button to calculate and display the results.

4. Plot Description:

   • Blue Curve: Required parachute diameter for the specified mass range.
   • Dashed Black Lines: Standard Rocketman parachute sizes with labels in inches.
