New Features that Contributors can Implement

Feature Name	Description	Programing Difficulty	Theoretical Knowledge Required
Rail Buttons	Finish rail buttons implementation, allowing for the calculation of loads they carry during launch.	Easy	Basic Dynamics
Plane Motion Flight Phase	Modified dynamics equations.	Hard	Advanced Dynamics
Custom Aerodynamic Surfaces	Create a new method in the Rocket Class that allows for custom aerodynamic coefficients such as Drag, Lift and Moment.	Easy	Basic Dynamics and Aerodynamics
Multibody Dynamics Parachute Flight Phase	Currently, descent under parachute is simulated as a 3 degree of freedom (DOF) system. However, parachutes can and should be modeled separately from the rocket, creating a 6 (DOF) system, 2 for the parachute (spherical constrain) and 3 for the rocket. This can greatly enhance the prediction of the landing point.	Hard	Dynamics
Graphical User Interface	Desktop or Web graphical interface that can be used to run RocketPy in a more user friendly way, possibly also writing the code so the user can learn how to used RocketPy as a module as well.	Medium	None
3D Rocket Attitude Animation	Create a 3D animation of the rocket's attitude during flight, allowing the engineer to better visualize the behavior of the rocket. Can also me used for marketing purposes.	Medium	Quaternions
Custom JSON weather files	Add option to import weather conditions as JOSN files such as those used by Windy.tv .	Easy	JSON
Rocket Add Discrete Controller Method	Add a method to the Rocket Class that allows the user to set a time-discrete, closed-loop, control function to be simulated during the flight.	Easy	Basic Dynamics and Basic Control
Rocket Add Continuous Controller Method	Add a method to the Rocket Class that allows the user to set a time-continuous, closed-loop, control function to be simulated during the flight.	Easy	Basic Dynamics and Basic Control
