Hey Everyone!

Welcome to Part 3 of my rocket engine series. This video goes more deep into overexpanded and underexpanded flows and expains why it is preferred to have multiple smaller nozzles (seen on most rockets like the Falcon 9, Falcon Heavy and the Space Shuttle), over one large nozzle.

The concepts covered in this video include the following:

1) Thrust Equation
2) Area-Mach Relation
3) Overexpansion
4) Underexpansion
5) Importance of controlling the pressure inside a nozzle
6) Nozzle Side Loads

Thanks for watching!
