New Features that Contributors can Implement

Feature Name	Description	Programing Difficulty	Theoretical Knowledge Required	Current stage
Rail Buttons	Finish rail buttons implementation, allowing for the calculation of loads they carry during launch.	Easy	Basic Dynamics	Not started
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	Not started
Custom JSON weather files	Add option to import weather conditions as JOSN files such as those used by Windy.tv	Easy	JSON	Almost finished
Airfoil profiles	Currently, the Rocket class supports only flat fins, although the fins in real life can have more sophisticated aerodynamic profiles. To start solving this problem, we could allow the user to change the CLalpha of the fins before simulating.	Easy	None	Finished by @brunosorban
Geodesic models	Make RocketPy capable of converting impact coordinates to useful lat / lon coordinates, based on different models of cartographic representation, such as WGS84 or NAD83 data.	Easy	None	Almost finished
Recovery Class	Create a new class regarding all parachute calculations and analysis.	Easy	Bascic OOP	Not started
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	Not started
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	Not started
Parachute initial force	Calculate the Parachute deployment impact forces	Medium	Rocketry Parachute literature	Not started
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	Not started
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	Almost finished
Elevation profile data	Since the Earth is not flat, we can implement some functions that allow us to more accurately determine the impact coordinates by researching the point at which the rocket crosses the Earth's relief. Good candidates for this job are SRTM data.	Medium	None	Started by @Gui-FernandesBR
Export pressures	Improve the exportation of pressure values to facilitate the simulation of the apoggee detection algorithm. It currently supports the "noisy" pressure output only after parachutes have been defined.	Medium	None	Not started
PyRX + RocketPy	Integrate the GUI telemetry software PyRX with RocketPy	Medium	None	Not started
Maximum distance	Calculate the maximum distance between the rocket and the Telemetry base station. The objective is to improve the choosing and testing of the antennas.	Medium	None	Not started
Optimize apogee detection algorithm	Optimize the detection filter coeffitients for the specific launch.	Hard	Adaptive Digital Filtering and C++	Started by @guilhermebene and @Lucas-KB
Plane Motion Flight Phase	Modified dynamics equations.	Hard	Advanced Dynamics	Not started
Hybrid/Liquid Motor	Derive the equations of motion for non-constant propellant center of mass.	Hard	Advanced Dynamics.	Started by @lucasfourier
Integration with Fusion360 (or similar)	Make RocketPy able to read a 3D geometry file that contains the entire Rocket description. This could save us a few minutes, as we would no longer need to measure multiple distances in our CAD software.	Hard	Autodesk Fusion 360 API	Not started
Parachute oscillations	Analysis of all Parachute stability	Hard	Rocketry Parachute literature	Not started
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	Not started
Deployable Payload simulation	Allow RocketPy to simulate the trajectory of objects deployed during flight	Hard	Dynamics	Not started
