The Icarus Rocket Simulator is a realistic, 3D, Rocket simulator designed to model a wide variety of variables and factors influencing the design and flight of a large Rocket.

Many "Rocket Simulators" that I have found on the internet are either designed for small "Model Rockets" only, or are specific to a particular rocket, for example the Space Shuttle. I was not able to find a realistic simulator that allows a user to model a completely unique, large, space rocket of their own design.

The Simulator uses real-world rocket equations for Delta-V, Specific Impulse, Exhaust Velocity, and many others. It models values such as Heat Capacity Index, Chamber Pressure, and exhaust pressure, as well as allowing users to choose a variety of fuel and oxidiser types. It also features a  realistic  Gravity, Drag, and Orbital Mechanics system as well.

I intend to eventually model the entire solar system, as well as allow rockets to leave the solar system after escaping the Sun's gravity. I intend to include multiple modelling and simulation tools, including rocket engine calculators and modelling to design the most efficient engine based on size, fuel flow rate, fuel and oxidiser type, etc, and of course, a rocket modeller, allowing the user to build their own single or multistage rocket, using liquid and/or solid fuelled engines, as well as their choice of fuel tanks, payload weights, stage seperation options, etc etc.

The current state of the project is relatively close to a concept release. I have modelled the Sun, the Moon, and the Earth, and I have added orbital mechanics and a simulation of the Rocket's Flight. The Gui's and modelling tools still need to be done, but most of the code work is at an advanced stage.

The Starfield, Earth Texture, and Moon Texture are all high resolution images released into the public domain by NASA.
