Run the Script Maple.m to generate all the Plots and Dynamics Equations for the Autorotating Maple Seed Payload.

The Script Produces:

• Shape of the Maple Seed Payload
• Twist Angle for 3D Modelling
• Angle of Attack of the Propellor
• Lift Coefficient vs the Distance from Center of Mass
• Accelaration wrt time
• Descent Velocity wrt time
• Displacement wrt time
• Angular Velocity wrt time

• For Design we have used the following functions :
  • find_chord.m : This function calculates the Chord length for each segment of the Maple seed at a distance 'R' from the Centre of Mass.
  • find_theta.m : This function calculates the angle between the chord of each segment and the horizontal i.e. Angle of Twist.

• For Dynamics we have used the following functions
  • find_alpha_cl.m : This function calculates the effective angle between the chord of each segment and the horizontal i.e. including the Angle of Twist and the Angle between the Vertical and tangential velocity.
  • find_surface_area.m : This function calculates the effective surface area that provides the Lift.
  • Maple.m : This script contains the equations to calculate Lift, Drag, distance, velocity, acceleration, angular velocity and angular acceleration using the above functions.

• Dowload and unzip all the MATLAB codes(.m files) into the same folder.
• Then run the MATLAB script Maple.m to generate the plots
  • chord length v/s R
  • Twist angle v/s R
  • Angle of attack v/s R
  • Coefficient of Lift v/s R
  • acceleration v/s time
  • velocity v/s time
  • distance v/s time
  • Angular velocity v/s time
• The values of initial velocity and mass can be changed within the MATLAB script Maple.m
