No way!!! I have spoken with you about 2~3 ago, regarding lean angle for bikes, I even sent you some material to check out, now I ended up watching this video because I have an interview in a company that deals with hydrogen.. You’re very good at this! Keep up🫡
Best explination I have found. Would be interesting for you to do the Engine start and explain the parts of it next. The order of start and the things to avoid to prevent ruining the engine.
I find it amazing that in the 501, about 75% of the thrust comes from the fan via the bypass shroud. In fact, the plane was first known as the "Fanjet 500" during the prototype stage, probably to emphasize the quieter and more efficient performance of the high-bypass turbofan compared to competitors like Learjet.
@@FlyWithNoam Sorry, misread that. Makes sense. Edit: But the fan is also feeding the high pressure compressor, so that air feed would go down with altitude as well. I was just reading that bypass ratio doesn't actually change with altitude.
@@FlyWithNoam It's one thing to see a static photo in a book, but much better to see it explained this way. Especially how the low pressure turbine drives the fan with a shaft going through a hollow N2 shaft. That wasn't obvious to me before.
Good job explaining the very basics of jet propulsion. Except that the fan in a turbofan is *_not_* a propeller, it’s a compressor. It works just like the compressor of a pure turbojet engine except it’s much bigger and compresses the bypass air along with the air that enters the turbojet. The compressed bypass air expands and accelerates out the back of the fan’s should to produce thrust. All of the fan’s energy goes into compressing the bypass flow so there’s no energy left over for it to produce any thrust of its own. Ducted propellers are still a real thing, except they’re used on blimps. Though when it comes to turbofans, ironically it’s actually the low-bypass engines of modern day fighter jets whose fans (fighter engines typically have three fans) produce thrust like a propeller! But don’t take my word for it, I’m only relaying to you what various aerospace engineers and aerodynamic physicists that I’ve encountered have told me.
@@FlyWithNoam You're certainly welcome! Unfortunately, many people interpret the propeller analogy way to literally and think that turbofans are identical to turboprops excluding the shroud that encases the fan. But yeah, the main reason why turbofans are so efficient is because most of the air entering the engine bypasses the core and produces jet thrust without getting mixed with fuel and burned unlike in a turbojet.
@@FlyWithNoam Yes, I know. Pilots are actually taught dumbed down versions like that one because they mainly need to know how to fly the plane including what the engines do instead of learning how the engines do it. I'd also like to thank you for being open-minded. Other aviation enthusiasts often lose their temper because I don't believe oversimplified explanations and they refuse to update themselves when I tell them that aeronautical engineering is more complicated.
@@FlyWithNoam Yep... as one of my favorite songs goes: "All lies and jests, still a man hears what he wants to hear and disregards the rest." - Simon & Garfunkel (The Boxer)
Hard to understand how the fan (“propeller”) doesn’t limit the aircraft speed to under ~500mph. Even with the N-1 thrust, wouldn’t the fan become a huge drag at high speed? Thinking how the XF-84 top speed was 520mph, fastest WWII prop fighters well under 500mph.
Excellent infographic! Give this video some time, the algorithm will eventually spread it to other aviation video enthusiasts...

You’re very good at this! Keep up🫡
This was a great explanation - could never understand the compressor part of the engine but you explained perfectly! Thanks
Incredibly clear explanation, Noam! Well done!
That was a great tutorial. Thank you. Now back to the ACS... ugh.
I appreciate you making these videos. Easy to understand and very informative.

The order of start and the things to avoid to prevent ruining the engine.
Short sweet and concise, best explanation ... newcomer to the channel, will stay indefinitely. Fly safe my friend.
Fantastic explanation !
What a great voice 🙌

@@FlyWithNoam I don't recall if they mentioned an altitude. But yes, could well have been at cruise at 410.

great Turbo fan video
That was excellent, thank you.
Thank u so much.....

I love your OnlyFans content. Lots of great info about the fans.

@@FlyWithNoam so many abled corp jets out there that need new panels. this is a game changer
