Explained Turbojet Thrust Equation

Let's derive the thrust equation for a turbojet engine! In this video I'll show you how to derive the thrust equation for a single-inlet, single-outlet air breathing engine (turbojet is kind of just a buzzword here, because the engine doesn't necessarily need to only be a turbojet). • Yes, this video is heavy on the math, but I'm planning on starting a video series called 'In a Nutshell', which will take some of my math-heavy videos and break them down in to shorter, more easily understandable videos that focus on the big picture. Stay tuned for those. • ===== RELEVANT VIDEOS/LINKS===== • → Mass Conservation Derivation • https://goo.gl/Qx7PZ6 • → 1D Mass Conservation • https://goo.gl/hM46LU • → Momentum Conservation Derivation • https://goo.gl/DuYHcG • → 1D Momentum Conservation • https://goo.gl/8uo6VM • → Surface Area Blog Post • https://goo.gl/1s2z2X • → Turbofan Thrust Equation Derivation • http://www.joshtheengineer.com/2017/0... • ===== EXTRA LINKS ===== • ► This is the Wikipedia page for Turbojets, and while I don't tend to like Wiki pages for math, take a look at the 'Net Thrust' section. • https://en.wikipedia.org/wiki/Turbojet • ===== ASSUMPTIONS ===== • 1) Flow is reversible external to the engine • 2) Steady state • 3) No viscous forces • 4) No heat addition • 5) No body forces • 6) Velocity only has X-direction component • 7) Momentum from fuel flow rate is negligible • ===== THUMBNAIL PICTURE ATTRIBUTION ===== • By Jeff Dahl [GFDL (http://www.gnu.org/copyleft/fdl.html) or CC BY-SA 4.0-3.0-2.5-2.0-1.0 (http://creativecommons.org/licenses/b...)], via Wikimedia Commons • Modified slightly by me
