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.

[@hcrawford]

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!

[@LSF315]

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

[@tnekkc]

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.

[@allmonkeysallthetime]

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.

Good stuff. I was a crew chief on 16's. I was stationed at JBA. Fighters are a little different but I would have loved to have been on heavys.

[@ruirodtube]

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.

[@wampaku2]

ruirodtube that may be true with other aircraft, but this particular airplane does not rely on motive flow and the fuel pumps never shut off.

[@ruirodtube]

Joe Brown that's interesting. I wonder why the manufacturer would rely on mechanical boost pumps rather than passive jet pumps. I would think pumps would increase maintenance costs a lot. The boost pumps being located in the wing tanks must be expensive to replace periodically because they are critical to the operation of the engine on this model. Strange. Do you know when they are energised and when they shut down?

[@wampaku2]

Yes. The fuel pumps in the 145 are turned on when the airplane is turned on. They are only turned off during fuel cross feed, or when you turn the airplane off. They are very reliable pumps. I probably have close to 10,000 hours in the 145 and can count on one hand the number of times I've seen a fuel pump fail. Fuel pump MELs are fairly rare too. I think I've only seen one in the last 5 years. Maintenance costs can't be that high.

[@cmans79tr7]

I noticed that stevo1kinevo does not relax when he starts his turboprop, he occasionally mentions he doesn't want a "hot start" can i impose upon you to explain a "hot start and why that is dreaded so much? Great explanations here. I'm glad I clicked on this suggested video.

[@dougcerveny8446]

Basically a hot start is when the ITT (temperature inside the engine) becomes to high/hot and can damage the engine. It can be from a number of things, but if a hot start happens and the fuel is not taken away it can cause parts of the engine to fail or break. Your buddy doesn't want a hot start because it could potentially mean having to rebuild or buy a new engine.

[@bazil83]

This video was especially fascinating to me as I'm sure I was on a flight last week whose APU had failed so they had to start using the bleed air system, as outlined in this video. I suspected at the time, so searched just now and found this video. Basically, we were about an hour delayed for pushback, pilot said they had a number of system failures. I was sat right at the back (777, in the row with just two seats next to the window instead of three - best seat in economy after bulkhead seat - extra leg room), and during that hour delay, I kept periodically heard the sound of a turbine spinning up for a few seconds and then winding down. I figured this was the APU and that they were having issues with it (I knew as much as the APU isn't really needed during flight, so wasn't too fussed), after a while, I heard a few thuds and clicks from underneath the plane, shortly afterwards one engine fires up and then we push back. We sat on the tarmac for a while, before I once again heard the sound of a turbine spinning up and then shutting down. The engine that was lit then spun up quite high for about 45 seconds and then returned to idle, at which point I realised the second engine had started. At the time I didn't realise a bleed air start needed the other engine to be at highish thrust. Tl;dr - I was on a plane last week I'm pretty sure had to do a bleed air start.

[@Ponderforge]

Thank you. I think you're the only place on the internet to explain how they initially start spinning.

Great video - just a nitpick from someone in the industry though, your definition of "hot section" and "cold section" is a bit off. The cold section is comprised of both the fan and all of the compressor stages, everything upstream of the combustor. The hot section is the combustor along with the downstream turbine stages, nozzle, etc. Your diagram labels the entire core engine as the "hot section".

[@doug440]

Ok video- some of the terminology was off: The "Hot Section" usually refers to the combustion/turbine sections, and not the compressors. Bypass air isn't used for bleed air applications, since it has very little pressure and close to ambient temperature. "Bleed air", or customer bleed is the term for air pulled off the compressor section to supply low pressure or high pressure, warm air for airstart, cabin pressurization, airfoil or inlet anti-ice, etc.

[@wampaku2]

augustine22 safe? yes. easier to start with a cart? No. APU assist start is a lot easier.

[@knightdaleknights44]

Yes. The engines start using compressed air, supplied by the APU. If the APU is broken, you have to start the engine using an external air cart. It is much more of a hassle starting an aircraft using an air cart versus an APU though there are some types of jet aircraft that can only be started using an air cart.

[@meerkatandpug]

It's actually not safe, and this has caused crashes in the past but it's still permissable to fly with a broken APU otherwise it could cost the airline MONEY.

[@wampaku2]

It is safe. The APU is shutdown in the air, unless an engine driven generator is MEL'd necessitating the APU generator's use. If both an engine driven generator and the APU generator is MEL'd the aircraft would be grounded. There has never been a crash caused by an inoperative APU. It's function is primarily air for air-conditioning, and engine starting, and electricity on the ground until the engines can be started. Then you can use the electricity from the engine driven generators and bleed air from the engines to operate the air-conditioning.

[@dashamanstevo5326]

Combined gas laws, increase the pressure of a gas while keeping volume constant, the temperature will increase. By stage 14 (I think they said) pressure is high with volume being constant, therefore by the time the air reaches the diffuser to the combustion chambers, the temperature will have increased significantly.

[@oscarb9139]

@@dashamanstevo5326 The hot section starts at the combustion chamber.

[@mikelewis3382]

I built over a thousand hot sections as well as complete engine assemblies at Curtiss -Wright on Pratt & Whitney j-57 and other manufacturers' engines and the hot section is built as a seperate assembly and I can assure you it starts with the HPC turbine and is capped off with the high speed turbine, after the diffuser, fuel manifoild, combustion chambers / cans. You lift that up and marry it to the cold section / low pressure turbine, and tie it all together with the ass end low speed turbine long shaft that threads into the cold section frone end turbine. In the factory that high speed turbine is built by one guy and is brought to the hot section assembly area in a dolly. The hot section IS that part that is all tied together by the high speed short shaft turbine. Look at the drawings. It's a whole seperate assembly.

Designandrew Based on the same logic so you're not far off there.

[@indyjons321]

0:53 *WRONG!* It goes "Air, Money, Noise"

[@GeoffreyEngelbrecht]

Not completely accurate. I design ground based gas turbines for power plants. Fuel will burn in the combustor at atmospheric pressure. It doesn’t need pressure to burn. That isn’t the reason you need to supply compressed air to the GT to start it. The reason a GT needs compressed air is to pre-spin the rotor. This is done because the GT generates power from the principal that more work is extracted expanding hot gas than compressing cold gas. If the GT isn’t pre-spun the combustor will be at atmospheric pressure and the hot gases from the combustor will not generate any power in the turbine since there is no pressure difference for those gases to expand with. Thus the turbine will not drive the compressor. If only a small amount of pressure is generated in the compressor then the turbine will generate some power but at low pressure ratios this is not enough to overcome the friction losses in the turbine and the GT will deccelerate. So the GT needs to be spun up to a critical speed over which it is able to generate more power in the turbine than the compressor and friction losses consume and then the GT is able to accelerate on its own from there.

[@tommykebschull9439]

Geoffrey Engelbrecht very well explained thank you

[@abbasali3100]

Yes but GT at the power station has huge turbine since you need kinetic energy. But with jet turbine it's so small since you need the energy to drive the compressor remaining is required for building thrust.

I started Military Jets many times as a jet engine mechanic. The most fun you can have is doing an ops check on a newly installed engine. Trouble shooting is fun as well and can be a challenge. Suck, Squeeze, Bang and Blow gets giggles from the ladies. We used MA1A start carts to feed air to the engines for engine starts. The #2 engines were started first to allow the generator to supply power to the gauges since the #1 engine would not have electrical power to the gauges until after the #2 was running. The switch over of air was also performed on the #1 engine during start with the air cart. Our #2 engines didn't bleed air to the #1...it is just the way they were by design.

He did at 6:17. Great! I was looking for that.

[@HighCountryRambler]

Thanks for the great video, answered many questions sitting on a ramp wondering...

[@briankelly3931]

This was very cool and very self-explanatory and very understanding LOL even for me. Awesome

[@2006mct42]

3:29 Half a gallon each minute? Really. It got to be half a gallon each second

[@derpderpyface5246]

Half a gallon per minute is still a lot of fuel. Keep in mind a car can run for 10+ hours on one 16 gal tank. This (small) turbofan is chewing through 16 gal in 8 minutes.

[@MrNoah11992]

Wouldn’t it be 8 gal in 8 mins ?

[@MrNoah11992]

With two turbofans

[@derpderpyface5246]

lol, it would be, I royally fucked up my maths,

[@Jacksonkellyfreak]

@@derpderpyface5246 8 gallons in 16 min guys. one gallon every 2 minutes, and I work on these. They burn way more kerosene than that

“This happens more often that you might think” WHAAAAAATTT?!

[@jimfowler5930]

Very nice teaching/refresher video! Thank you.

[@davejohnsen8540]

Best explanation I've ever seen.

[@jamesscheidt4278]

Excellent explanation. I pretty much understood what takes place after start but I always wondered how it got to that stage. Thanks
