The project is the first try to program a mathematical model describing the trajectory and other properties of space vehicle during the re-entry into the Earth's atmosphere.

Simulation.Backend - a working folder of programmed maths models wrapped up in ASP.NET Core Web API app.

Simulation.Frontend - the frontend project in python written using StreamLit

Many thanks to other guys working on the project: Mattie Lousada Blaazer and Will Cliffe. Materials and ideas used in the project can be seen on the Miro Board

Simulation.Backend/Core shouldn't terrify you with its structure. We have kept it as simple as possible but scalable at the same time: SpaceVehicle is inherited by Shuttle and Capsule (2 types of vehicles you can generally have in rocket science 🙃 ) SpaceVehicle contains general equations to calculate different properties and derivations used in further calculations.

Shuttle and Capsule override CalculateBallisticCoeff() and CalculateLdCoeff() which are used to calculate Ballistic and Lift-to-Drag coefficients correspondingly as these properties are calculated different for each type of a space vehicle.

During the runtime, after set period of time, the state of a space vehicle is captured and recorded into the TimeFrame instance. When the space vehicle reach the minimum height, the simulation is stopped and the list of TimeFrame objects is returned.

No extra libraries are required for c# project. So, just make sure you have got dotnet 3.1 on your machine.

So, the code can simply be run by:

cd Simulation.Backend
dotnet restore
dotnet run #runs the web api app
dotnet test #runs tests in Simulation.Tests

Having set up the backend, you are ready to run the frontend which is dead easy:

cd Simulation.Frontend
pip install streamlit
streamlit run GUI.py
