# What is This?

Here's a brief explanation as to what this simulation is, what it does, what it can do, and what it can't do. As mentioned in the repo's 

description this is a model rocket simulation that is written in python. Just like the original RocketSim, this code takes custom inputs for almost every parameter of the rocket but is not visual like 

OpenRocket. Fortunately, that's where the similarity to the original ends, this code is not made as a python version of OpenRocket. This serves a completely different purpose, simulating rockets controlled via thrust-vectoring. Using this software, you can define your rocket's general design and control perameters to simulate it's response to various flight scenarios. For the moment, I have not tested the code to see how close its output is to a true flight and it's likely safe to say that the accuracy is a bit iffy, especially since it makes a few _possibly_ erroneous assumptions. Mainly, it assumes a that the rocket has throttle control, does not account for drag or the distance from the CG to CP, and likely makes several other bad assumptions which may or may not be a deal-breaker. Fortunately, I have plans in place to implement the changes necessary to mitigate these issue and improve the overall accuracy of the outputs.
