There are all kinds of sciences. Try to take as many as you can so you can get a taste of what it is about. Thanks for explaining about nacelles and combustors and turbines. Different HSCT designs produce different levels of sonic boom. It is a function of the fuselage and wing shapes, and the speed they fly at.
Nacelles are engine pods that normally sit under the wing.
The inlet is the part ahead of the engine that captures the air. The nozzle is the part behind the engine that re-directs the hot air to give you thrust. Mina thank you for your time and answers you are explanations were easy to understand. But I have to go so bye. Yes, I like leaving in California and miss my family very much.
