Ada Rocket Simulations

This project is an Ada port of the core physics and component hierarchies of OpenRocket, an open-source model rocket simulation software. It provides a highly reliable, strongly typed 6-DOF simulation engine driven by the Ada programming language.

Project Structure

The codebase is built using Test-Driven Development (TDD) and is structured iteratively into sprints:

• Core Math: 3D Vectors, Operations, Cross Products, and Scalar Multiplication.
• Components: Composite tree hierarchy of rocket components with recursive Mass and CG accumulation.
• Aerodynamics: Barrowman Equations implementation for calculating Normal Force Coefficient (CN) and Center of Pressure (CP), plus Stability Margin.
• Motors: Motor subsystem with thrust curves and dynamic mass reduction.
• Simulation: Full flight loop using Euler numerical integration for time, velocity, and position given thrust, drag, and gravity, with CSV data output.

Prerequisites

To compile and run this project, you need the Alire package manager.

1. Install Alire.
2. A compatible GNAT native compiler (Alire will download this automatically upon the first build).

How to Run

1. Clone the repository and navigate into the root directory:

   cd ada-rocket-simulations

2. Run the executable. It supports three modes:

   • TDD Test Runner (default):

     alr run -- --test

   • Load Rocket & Simulate (from XML):

     alr run -- --rocket test_rocket.xml

   • Load Rocket & Output Custom CSV:

     alr run -- --rocket test_rocket.xml --output flight_data.csv

   Note: On the very first run, Alire will fetch and set up the GNAT toolchain, which may take some time depending on your connection.
