Pmedic548 Posted November 26, 2020 Posted November 26, 2020 The shutdown sounds with the F14 update is awesome. I'd like to see the sounds of the 1st stage fan blades "clicking" during shutdown added to the F-16. It's a sound I'm well familiar with having been on the -16 flightline for 20 years.
ED Team btd Posted November 26, 2020 ED Team Posted November 26, 2020 The shutdown sounds with the F14 update is awesome. I'd like to see the sounds of the 1st stage fan blades "clicking" during shutdown added to the F-16. It's a sound I'm well familiar with having been on the -16 flightline for 20 years. Do you mean that "ratchet" sound that we implemented in L-39? If yes, and if you have worked near F16 for a long time, could you help us? because we do not have a single shutdown video from close range (and this sound cannot be heard from a long distance) So if yes, please answer is it like in my video for L-39? The sound should last the same amount of time? so long? 1 Best regards, Kanstantsin Kuzniatsou (btd) https://soundcloud.com/btd
Pmedic548 Posted November 29, 2020 Author Posted November 29, 2020 I can see if I can get you the sound. We no longer have F-16s but we are a repair center for the F110 engine and I can capture the sound of an engine spooling down in the Hush House. And it sounds pretty much the same as the L-39 spool down. And I'd say it's about the right amount of time.

Also, if possible, I ask you to record the startup, without a distortion and preferably with a minimum or without extraneous noise :) Best regards, Kanstantsin Kuzniatsou (btd) https://soundcloud.com/btd
Pmedic548 Posted December 1, 2020 Author Posted December 1, 2020 We are installing a F110 in the house for running tomorrow so I'll see about capturing some audio. Now since it's being run in the house there are no JFS sounds. To start the engine they will use bleed air from a -60 that is running outside. But the sounds should be clear. Not only does the house suppress the sound inside from being extreme outside, it blocks all the sound from the outside.
ED Team btd Posted December 1, 2020 ED Team Posted December 1, 2020 Nice. So far I made a test variant: As for FA18, pilots said: "Hornet doesn't have that noise, neither does the super hornet, only the T-45 does" 1 Best regards, Kanstantsin Kuzniatsou (btd) https://soundcloud.com/btd
Pmedic548 Posted December 2, 2020 Author Posted December 2, 2020 you will hear the sound stronger at the intake. The 1st stage fan blades on the F110 fit "loosely" and the blades have halfway up "wings" the midspan shroud. So when the engine spools down to where there isn't enough centrifugal force to keep them in place, that's when the rattle starts from the midspan's clicking together. Tomorrow morning I'll be at the hush house for the start up and shut down of an engine. I'll also see about showing you a pic of the fan, I think there is an uninstalled fan on the floor. I don't think I've ever really heard the "rattle" on the aft side of the aircraft. It's a long way down the intake to the engine (I've hopped down quite a few intakes, it's a long ways down.
ED Team btd Posted December 2, 2020 ED Team Posted December 2, 2020 Thank you very much for this interesting information. I used to think differently. I will fix the sound cone. If it's not difficult for you, send me the recorded sound by mail, please btd@eagle.ru Best regards, Kanstantsin Kuzniatsou (btd) https://soundcloud.com/btd
Pmedic548 Posted December 3, 2020 Author Posted December 3, 2020 I just sent you several files, and I was mistaken you can hear the rattle from the back. It's been a few years since I actually worked the jet its self.

We just need to edit the engine so that the rpm does not drop to zero so quickly. 3 Best regards, Kanstantsin Kuzniatsou (btd) https://soundcloud.com/btd
Pmedic548 Posted December 11, 2020 Author Posted December 11, 2020 I can't wait for the next update. Thanks for letting me provide you the sounds 1
JetCat Posted May 28, 2021 Posted May 28, 2021 Isn`t this the sound the mounting device for the individual turbine fan blades make when turning very slowly because there is a millimeter of space between the individual blade mounts? I have watched a documentation about turbines some time ago and the Cessna Citation turbines make the same rattling sound when turning very slow or when turning the N1 stage fan by hand.
