LOUD

Today, though, what looked like an F-18 flew over. Wow. I haven't
seen too many fighters in my life (still have yet to see a "real" air
show).

Duluth is only 150 mile straight up the freeway from MSP (Mpls/St. Paul)

We want to get up there for the Air Show.

Read recently (in an article I cannot now find) about an
airplane designed and built in the '60s or '70s that had a turbojet
engine in the tail and a huge turboprop in the nose. Supposed to be a
fighter or fighter-bomber. Only two were built, and after one flight
the test pilots didn't want to fly them any more. They were LOUD in
the cockpit or anywhere else. It hurt bad. Very few test flights were
carried out. I imagine they were designed to defeat the enemy through
intimidation alone. Apparently most of the noise came from the prop
tips, which were running supersonic or transonic, even in static
runups.
One of the pilots lived ten miles from the airbase, and he could
hear the techs running it up, on the ground, all the way from his
home. That has to be pretty bad.
Anyone here remember what it was?

You may have read about it in "Air and Space Magazine", if I remember
correctly. Not exactly sure if this is the aircraft in question but would
almost bet money on it. According to a senior curator I met at the Air
Force Museum when it was tested there it was painful to be anywhere near.

That's the one. Thanks!

ISTR it was nicknamed "Thunderscreech" because of its awful noise, and
caused pain and severe nausea to ground personnel in the vicinity when
the prop was turning.

I'd put an F-106 at takeoff up against almost anything. It was pretty
loud in general, but there were some godawful high harmonics in there
that made you feel like someone was ripping giant sheets of canvas *in*
your chest. When I worked F-4s, we had an ANG F-106 alert unit sitting
at the end of one runway, and when they took off, we'd go into the EOR
shack and hide for extra protection - after standing 100 feet away from
multiple F-4 launches on full afterburner all day...

"Pushme-pullyou" comes to mind. :-)

If you do a search for turboprop noise in the NASA archives you will
find the info - the surprising thing to me was that the noise levels
were about equal clear out to the sixth harmonic. Yes, the XF84H was
loud. But the Saturn 5 was mucho louder, but you couldn't get closer
than about 8,000 yards. OTH, standing about 3 feet to one side from
the nozzle of a J79-17 at max power is verrry interesting.

I'll second that motion.

While not a J79, the engine on the F-16 is quite impressive up close.
Did a job shadow with an F-16 crew chief and did final checks with him.
One involved lying under the aircraft and checking something just
forward of the afterburned turkey feathers. The noise was punishing.

You want loud? Or annoying?

UH-1H doing a nice slow deceleration at low tq settings will produce a
popping sound that is easily heard for more than a mile. And it last a long
time.

I was flying a CH-47D at 165 knots and the folks on the airfield said they
heard us coming for at least five minutes before they saw us. Man she was a
good ole bird.

Don't you all just love the sounds of freedom.

I reside about 6 miles off the departure end of MSP runway 12, so I'm
used to hearing a lot of jet traffic. I've only lived here for 6
months but I quickly adjusted to the noise. It's acutally not that
bad, excepting the venerable DC-9.

Today, though, what looked like an F-18 flew over. Wow. I haven't
seen too many fighters in my life (still have yet to see a "real" air
show). That thing peeled off to the southeast with a thunder that
even the DC-9 in full song can't match.

She was probably climbing through 3 or 4 thousand when I looked up.
Are afterburners used during departure? If not, I can't imagine what
_that_ sounds like.

B-47 taking off with RATO on!

Loud, yes, but WORTH IT! :

Harriers taking off from a short field a quarter of a mile from your squad
bay.

I live under the final for PDX. Every morning the F-15s come over (or roar
out overhead.) I'm exactly under the point where they lower their landing
gear, which means I'm exactly downrange when they throttle up to compensate.
Rattles my windows every freakin' morning. I'd take it as a free airshow
("the sound of freedom") but it sets the neighbor's terrier off for the next
half an hour or so.

I think B-1s are the loudest things I've ever heard personally.
