Loudest aircraft you have ever heard

[Cliff_Chambliss]

Loud but not the loudest but one of the most impressive.   Used to watch these as a kid. 

Six Turnin and Four Burnin

Wow what a howl that jet has.  Any jet is a good sounding one.  That is until they have the economy freaks come in and make the jets less smokey and loud

What were they chasing that B-36 with to film that? 
.. wonder if they'd ever do something like that again?


Quite a machine, but retired pretty quickly.. metal issues, no refueling ability limiting it's range ..

[bosshawk]

Not really limited in range: Castle AFB, Ca to North Africa and return without refueling???  Had a friend who was a flight engineer on B-36s out of Castle and he told me of flights like that.

The B-36 had some pretty long legs. It was slower then crap but it had range.
SAC did some pretty drastic things like eliminate all but the nose and tail guns and the gunners to try to get the weight down and to gain some speed.
Even with the jets, the B-36D was still a sitting duck against something like a MiG-15.

[bosshawk]

When I was in college, the school apparently was on one of the B-36 routes and a couple of times a week, while walking to class, I would hear one passing over at FL Infinity.  It took that plane forever to go from horizon to horizon.  Yep, slow!!!!  Now, the B-47 didn't have that problem.  There were very few fighters that could keep up with it, particularly at altitude.

What is the loudest aircraft you have ever heard in your life?

SR-71 demo at the NAS Point Mugu air show / "space fair" in the early '80's.  That was the first time I saw shock diamonds in jet exhaust.  That, combined with the noise and sheer SR-71 awesomeness left one heck of an impression.

Any Russkie first or second-generation commercial jet - an Ilyushin-62 is unbelievably loud at full power, rivaling a Concorde lighting off all four afterburners!

[planenut767]

Strangely enough the loudest aircraft I've heard was the Fokker F27 Friendship. I worked on an airport ramp where the FedEx feeders would come in. They'd usually have to power up a bit since the ramp area was inclined and to maneuver into their parking spots. The first time they powered up on me left my ears ringing and that was with noise mufflers on my ears. They also shook our break room (trailer) the way no 727 could ever do. Very surprising since I've been around a lot of jets over the years, but I guess a first generation turbo prop will do that.

OK, my vote is for the old B25Ds heavy weight takeoff. 8 J57 jet engines burning JP4 and water which lasted about 2 minutes. Well over 160DB. Of course this was way back when men thought you could burn water.

Didn't know the TWO Radial Engines on the B-25 were that loud...

Oh, you were talking about the B-52D with the 8 Pratt and Whitney J57-43WB turbojets? 
The D Model Buff carried about 1500 gallons of demineralized water for takeoff power. The water ran out at just about exactly 2 minutes.
This resulted in a 40% reduction in thrust. So you best be airborne with the gear and flaps up or it will be a rather short flight!

When water is heated past its boiling point, the expansion is about 1200 times its liquid volume. You don't need to burn it to make thrust.

I have been under a bunch of B-52H and they are kind of quite.

Kind of QUITE or QUIET?

[stillamarine]

Was at Kadena when they still had SR-71s when I was a kid. Always thought they were crazy loud. Harriers off the deck of the ship I was in in the Med used to wake me up every morning. But by far the loudest sound I ever experienced that was produced by an aircraft came from an AC-130 on a mountainside in Afghan. Talk about rocked my world!

The B-52H has TF-33 Turbofan engines. They are much, much quieter then the J57's. Put out a lot more thrust too.

My sources say that the max thrust levels are about equal, depending on dash numbers.

The TF33-P-9 engine puts out 21,000 lbs of thrust at the Maximum Continous Thrust setting.

The J57-43WB used on the B-52D puts out 13,850 lbs of thrust with water injection and 8,750 lbs without water.

Yeah, just a bit more thrust. And the TF33 burns a lot less fuel too.
But thats just because turbofans are always more fuel efficent then turbojets.

But what do I know. I just have about 25 years of experience flying on or maintaining aircraft with J57 and TF33 engines.

Oops. My bad I saw J79 when I read it. And you don't need to be so snarky.
