How A Jet Engine Starts

What's it take to get a jet engine up and running? There are a few ways to do it, and we'll show each one.

I`m 46yrs old and planning on going back to school for aircraft maintenance. I hope I learn this. It`s a career change for me, I love planes and finally doing something about it.

For the Eclipse jet, I designed a circuit that takes and analog of the engine speed in, and outputs an analog of starter torque.
This was to match the profile that Pratt Whitney in Canada engine manufacturer specified. The new engine still flooded sometimes. I was working for General Dynamics that supplied the starter/generator.

No stupid music, just clear concise information - well done.

So I'm at work and "Suck Squeeze Burn Blow" comes up as a coworker walks past my desk.

Guess it's time to update my resume.

Excellent, high quality and professional video. Very informative. Thanks!

I've talked to countless pilots and aeronautical engineers about how a turbine engine works. This is the first video that put it all together in an understandable format. Thanks!

These RJ pilots have been working on their “cool dude” voices for awhile...

Fascinating! I always wondered how they start a jet engine. My big learning point was that it's the bypass air that mostly provides the thrust. I always thought it was the hot exhaust air that did it.

[ShannonSmithu]

agreed, really well done, explained nicely without talking down to us, cool to understand now, thank you

Another day of where quarantine got me ....

I've been searching all morning for a clear and concise explanation of a jet engine. This is it. Thank you

Hello ExpressJet ERJ Pilots! I'm an ExpressJet ERJ mechanic! Glad to keep you guys in the air!

Thanks for the video! Used to be in M1A1 Abrams and loved how magic happens and how resilient the turbine engine was (they are turbine and not piston tank engines). Unlike aircraft, they have a simple button for starting and gauges that are designed to let you know when there is trouble and unless master warning or caution comes on, no need to take your eyes off the battlefield. Abrams (I would say tanks, but it is the only one) and helicopter electric starter motors are big, but nothing like starting a thrust driven plane. Still cool how a vintage '80s turbine control system can control a ~70 ton turbine driven tank reliably.

@0:50 "They run off a suck squeeze burn blow principal." Sounds just like my ex. 🤣

Great video. I worked the ramp for Skywest quite a few years ago so it's cool to see how things worked for the ERJ. We handled mostly CRJ-200 and 700's with some brasilias and Dash-8's for fun. I remember starting up the CRJ's with our enormous huffers. I'm not completely positive but I think we started both engines using the huffer before push. Always fun playing around with the big toys.

Modern engines rely on automation to sequence the start events precisely. We don't see it on the video but a lot more happens in the background such as boost pumps in the wing tanks automatically start feeding fuel to the engine and automatically stop once motive flow is established and ignitors momentarily glowing hot in the combustion chambre until the flame is self-sustaining and then shutting down. If it wasn't for automation the pilots wouldn't be so relaxed during the start up. You may catch a glimpse of the workflow on videos showing a PT6 Turbine starting.

Hey Guys - My son and I love watching your video series. The top notch content and production is appreciated.

[antityier]

No matter how much of this I already know, I always find myself watching these videos. This was most definitely an enjoyable video to watch.

[jamiereed]

Very well put together! I finally have a better grasp of how these work, thank you!

[jimbarrofficial]

This was very informative and easy to follow. Thanks for posting.
