Hi. I hope yall having a great day. I'm looking for a book or online website (including solutions if possible) that deals with solving various problems of rocketry, for example, its control sensors, parameters such as impulse, propulsion efficiency, altitude calculator etcetera using C programming language? Need this to smoothen my C skills when it comes to rocketry plus I want independence when it comes to using sensors. Don't wanna spend money buying them. And also I can play around a lot with the rockets that I build.
