Introduction to Rocket Science and Engineering

Here's an answer that might satisfy you: Aerodynamics Introduction to Rocket Science and Engineering Fundamentals of Astrodynamics The simple answer to your question is "no".When it comes to military jets, it's "designed by people with PhDs, built by people with masters degrees, operated by people with bachelors degrees, and maintained by people with high school diplomas." (Note where you are) Not a perfect explanation, but it gets the point across. Given ten years, you might be able to make a dent in rocket science, but you will not master it. The answer that might annoy you but be the most viable is:Master mathematics on Khan Academy (especially the basics. Do as much of it without a calculator as possible, and study model rocketry resources. Start with that Model Rocketry Study Guide. Also maybe try to familiarize yourself with Python. Inevitably, you will need undergraduate-level studies. Take linear algebra before multivariable calculus. You'll thank me later. Statics would also be good to take before multivariable calculus and would dovetail nicely with linear algebra. I would prescribe something like: Calc I Programming in Python some sort of engineering fundamentals Calc II Microeconomics (everything requires a budget) maybe some more programming; pick up an Arduino or something Linear Algebra Statics Physics I Calc III Dynamics Physics II Diff Eq Mechanics of Materials Physics III Fluid Mechanics That's about 2½ years of university there. Anything beyond that will take a more qualified person to answer. All you get at that point is a solid foundation in mathematics, physics, and engineering. The more solid you can be on these things, the easier your life will be. You have to ask yourself whether you want to struggle with your courses or enjoy your courses. Enjoying your physics courses takes a great deal of mathematical maturity.

I highly recommend this book: Introduction to Rocket Science and Engineering https://a.co/d/bIeTRA8 It has really great content. The math for rocketry is going to be out of your league for 14 years old. That's going to be true no matter what. The cool thing about the book above is that even after you skip the math, there is tons of content left to understand the challenges of rocketry. Differences in propulsion systems, how multi-staging works, how orbital maneuvers works... EDIT: I don't meant to sound insensitive when I say "math is out of your league". I'm basing this on typical education path where many of the mathematic tools used for rocketry aren't taught until later. Also - it's not all about math!! Depending on your area of interest, you can be successful in rocketry without too much math. I worked as a software engineer at SpaceX and then a smallsat company for almost 6 years and did plenty of cool stuff (including work on propulsion systems) and I never had to use any of the math from this book or any other. What I used however was all of that other knowledge from these books outside of the maths.
