Engineering

Just finished this textbook (Introduction to Flight, also wrote compressible flow), took about a ~month or two. Skimmed it (obviously) but solid. Good refresher overall. Glad I did it. 

Some thoughts:
- Ch.1~6 was a lot of basic aerodynamics, airfoils, etc
- Ch.7 was just control systems review
- Ch.8 astronautics 
- Ch.9 Propulsion, started to get interesting: I'd actually never heard of arc-jet thrusters before, turbojet, turbofan, ramjet, scarmjet, electric propulsion options
- Ch.10 Hypersonics: compressible flow, need to learn more about compressible flow

Good. Took notes but I probably won't read them. Ok, onto the next.

wow that sounds super exciting especially discovering new propulsion methods like arc-jet thrusters and hypersonics
