Sound of turbojets and rockets

[chornedsnorkack]

How does the sound of a Concorde - 4 turbojets with reheat generating something like 70 tons thrust in total - compare with the sound of a shuttle - 5 rockets lifting a 2000 ton assembly vertically?

And what are the other loudest planes?

Boeing 707?

DC-8?

B-52?

Valkyrie?

Backfire?

Does this answer your question?  8-) The loudest aircraft I've ever seen is The Rockwell B-1b.

The shuttle is audible 60 miles away .... and when they do engine tests they clear a 6 mile radius round the test site.

Yup, VC10 gets my vote. When ever we get one through EDLP, it is the only aircraft that sounds like it is trying to rip the hanger out of it's foundations.

The space shuttle is louder than anything.
This guy got closer than the 5 or 6 mile radious http://www.youtube.com/watch?v=Gn5odETw3Yc

45 seconds to the sound barrier (from lift off not video start), somehow I expected it to be quicker under the circumstances. I suppose it would have to be that "slow" to take account of the denser air at a lower altitude and it's subsequent resistance.

Well, at least VC-10 does have bypass. Vulcan has Olympus turbojets, but is much smaller than Concorde, or Tu-144 for the matter.

Just!

Having done deep strip on Conway's, it is only just a bypass engine The amount of noise that it makes you would think that it was either stuck in permanent reheat or it was trying to be a turbojet.

They test the shuttle engines in south Mississippi.

They test the shuttle engines in south Mississippi.  The test site is surrounded by a 10 mile buffer zone where no building is permitted and no one lives.  My parents live about 20 miles from the site, and it rattles their windows every test.

Cheers for that ........ I knew there was a large radius around the test site ....... larger than I thought.

Which is louder - VC-10 or B707-420?

Having heard both at the same time (in a previous life on a very desolate and isolated part of Scotland many moons ago), I would put my money on the VC10. Or to put it another way, does the 707 make your ears bleed  :o

The loudest thing I have ever heard in my life was an EE Lightning chained down on a test pad at RAE Farnborough back in the 1950's. I had just arrived for services day on the Thursday & was making my way to the spectator area. They were running both engines flat out & then started the Scorpion rocket motor mounted between them. My ears are still ringing.

I swear this is true although I've never seen it mentioned anywhere or seen a single photo of it.
