Sounds like a sawing noise like a circular saw. Maybe grinding inside the engine, however there doesn't seen to be any lose of power. You guys gained 10,000 no problem. Maybe a compressor pump?
There aren't any issues with the engine. The "buzz-saw" noise is common on many aircraft and is generally understood to be from the outer tips of the fan blades going supersonic.
I don't remember hearing that same buzzz saw noice from domestic flights early this year and an international flight overseas. Since May 2024 are some airlines going to this design characteristic? I did fly on a Southwest flight to LAX in May, sat in almost the same row and I didn't hear that same noise.
@@josephwright108 It's not an airline specific thing per se. Some airplanes have different engine options. For example, the 757 could be ordered with either Rolls Royce or Pratt & Whitney engines. A320NEO's can be ordered with either LEAP1A's (very similar to the LEAP1B's on the SWA MAX8 in this video) or P&W engines. So engine sound may vary from one airline to another depending which engine option they selected. But 737's, either NG's or MAX's, don't offer engine manufacturer options. The NG's have CFM56's and the MAX's have LEAP1Bs, so no matter which airline your ride on, the engines will be the same. Keep in mind that we calculate Takeoff thrust settings for every departure, and since conditions are always different, the thrust settings are always different. Calculated thrust values can be affected by things like weight, runway length, weather, runway condition codes, terrain or obstacle clearance requirements, and a bunch of other factors. So it's not uncommon for the engine sounds to vary from one takeoff to the next, even in the exact same airplane.
The beautiful sound of a LEAP engine!
Nice video. One nitpick, I believe the nomenclature is 737-8, MAX8, or sometimes -8M. The Max isn’t referred to as the 800 series.
B38M is how it would be displayed in FlightTracker.
Why not going on old Boeing 737
It changed.
@@southwest0092 ok

That's how LEAP1B's sound.
