737 MAX-8 engine start on a hot afternoon

[@Gamerguy-501]

That is definitely music to my ears!! Those engines are monsters!

[@andow21]

As RSE with ⚪️💙 I love I mean love saying “clear to strrrarrrrttt engines!” On push back and hearing the max hummmmmmm it always brings chills down my spine and happiness!

[@adl320]

Reminds me of the “extended dry crank” on the IAE V2500s. The start times are not always the same and depends on multiple variables, environment being but one that the FADEC considers.

[@theblacklexluthor11]

The 767 would do the dry extended crank from time to time but I'm curious to know is it the engine you referring to?

[@theblacklexluthor11]

Reminds me of the 767-300 and 300 ER start up!!

"United Together" except for that one Asian doctor.

Unfortunately that dr case didn’t have much to do with the airline the cops are the one that drug him off plane but normal people only see the name on side of plane Most the general public don’t understand that just cause you buy a ticket doesn’t really entitle you to anything… it’s still a privilege and a privately owned airplane that is federally regulated… very unfortunate situation

[@starpawsy]

If you look at the central spiral, it never actually spins very fast. It only SOUNDS fast because there are a lot of blades.

[@monkeybusiness1.21Gwh]

At MTO power the fan (N1) turns at roughly 4.6k give or take some hp N2 at roughly 20k LP N2 4500

[@starpawsy]

@@monkeybusiness1.21Gwh I accept your figures. My point exactly. This is not MTO power, this is only idling.

[@F16jetnyeow]

perfect music for sleep

[@Maxumized]

On a few of the MAX-8, DEEZ-2NUTZ have been observed

Those CFM56-LEAP1A'S are sick

[@broddsaviation5471]

It’s the Leap-1B’s that are mounted on the Boeing 737 MAX’s, Leap-1A’s are on the Airbus A320Neo’s and Leap-1C on the Comac C919 :)

[@broddsaviation5471]

@@onebadthe4749 the A220’s have the PW1500’s as standard, hence the howling sound during takeoff

[@roberts9095]

This is a LEAP-1B, but I agree the -1A is superior 😉

[@roberts9095]

​@onebadthe4749 currently, the PW1500G geared turbofan is the sole propulsion option for the A220. Airbus has however announced intentions to integrate a second engine option, most likely the CFM LEAP.

[@Johnny64ism]

sure took a long time 2 light off

[@monkeybusiness1.21Gwh]

It goes through several self evaluation Sequences and self diagnosis and will only start in certain stages if everything is perfect to keep from damage the engine that’s pretty much the short of it

[@Johnny64ism]

@@monkeybusiness1.21Gwh aaaah okay makes sense. All jet engines should do that..Would greatly cut down on inflight Engine failure's

[@monkeybusiness1.21Gwh]

@@Johnny64ism yes correct but the technology in this engine it starts in stages Good call on noticing the time it takes to come to full ground idol …the kind of comments I’m looking for 👍🏻😎

[@TheN747]

@@monkeybusiness1.21Gwh My friend who is a Max pilot was telling me a part of the long start time too is that because the central drive shaft to the fan is so heavy, it actually saggs a fraction of a millimeter when not running, so the as the engine spools up they have to give it time to warm up and straighten out before kicking it into high speed with the introduction of fuel. That’s pretty cool!

[@jefferyjin5551]

It takes 3 times longer to start than it’s predecessor CFM56

[@monkeybusiness1.21Gwh]

Yup there is a lot going on there if after a 7 hour cool down up to 90 seconds if before 7 hour cool down up to 120 seconds, it’s called a bowed rotor start 15 million dollar masterpiece

That engine is amazing lots of new technology

[@isaiahshultz4296]

Why does it sound like an fa 18 super hornet starting up

[@monkeybusiness1.21Gwh]

Cause they are both equally bad ass 🤘🏻

[@Star-bp5jj]

Both 737 and F18 Hornet are made by Boeing... Im assuming some similar designs in Start up. Just a guess.

[@TheGreatPapyrus458]

What engines does that max use?

[@monkeybusiness1.21Gwh]

It is a GE LEAP1B an amazing engine goes through several self test during start up to keep from hurting its self like oil pressure ,hot start make sure computer IE FADEC is all working properly before continuing the start process
