SR-71 Blackbird

[JMF]

Finally saw an SR-71 Blackbird today at the Duxford Imperial War Museum here in England, always been my favorite plane, the thing is so mean when you see it in the flesh

   they have an SR-71 in the lobby of the cosmosphere in hutchinson ks.  we went and saw it last year during charger fever

No nothing about planes, but I know and love the SR-71

[mikepmcs]

I love all aircraft as well. Thanks for sharing.

Here's some SR-71 info for ya. Well, what's posted anyway.

I am about 3 blocks from that plane!

awesome aircraft    don't they leak fuel when  parked 

Yes. Once the plane is up to speed and heats up (and stretches) the leaks seal but on the ground the stuff just pours out. That's why they need to refuel almost immediately after takeoff. Very cool planes.

A few more fuel details...

Fuel

SR-71 development began using a coal slurry powerplant, but it was determined that the coal particles damaged engine components. Then began research into a liquid hydrogen powerplant, but the tanks required to store cryogenic hydrogen did not suit the Blackbird's form factor.

The focus then became somewhat more conventional, though still specialized in many ways. The result was JP-7 jet fuel, which had a relatively high flash point (140 °F, 60 °C) to cope with the heat. In fact, the fuel was used as a coolant and hydraulic fluid in the aircraft before being burned. The fuel also contained fluorocarbons to increase its lubricity, an oxidizing agent to enable it to burn in the engines, and even a cesium compound, A-50, which disguised the exhaust's radar signature.

JP-7 is very slippery and extremely difficult to light in any conventional way. The slipperiness was a disadvantage on the ground, because the aircraft leaked fuel when not flying, but at least JP-7 was not a fire hazard. When the engines of the aircraft were started, puffs of triethylborane (TEB), which ignites on contact with air, were injected into the engines to produce temperatures high enough to ignite the JP-7 initially. The TEB produced a characteristic puff of greenish flame that could often be seen as the engines were ignited. TEB was also used to ignite the afterburners. The aircraft had only 20 fluid ounce (600 ml) of TEB on board for each engine, enough for at least 16 injections (a counter advised the pilot of the number of TEB injections remaining), but this was more than enough for the requirements of any missions it was likely to carry out.

 I don't think Kelly Johnson ever got his due,.. we shoud have a Natl. Holiday for the Man if ya' ask me... 

[mikepmcs]

Almost as impressive is the fact that he earned his Masters in AE in a year after Lockheed turned him down in 32'.  He was definitely one for the ages.

SR-71's are awesome.  Not many technological devices still inspire awe from new generations 40 years after their introduction.  (Muscle-era Dodge Chargers are also on that short list.)




I saw one of those MoFos on display in Tuscon last year. 

Even sitting in a hanger full of other important planes, there's an unreal quality about it.  You stand there walking around it . . . it feels more like some giant plywood sci-fi movie prop.  Your mind tries to argue with you that this object in front of you can't really do all those things it's so famous for.  Vehicles that look like this are supposed to be purely whimsical artistic creations with fictional performance numbers. 

It's like standing in front of a Batmobile prop car on display, and trying to convince yourself that this thing is ACTUALLY bomb-proof and capable of cruising at 200mph like the sign in front of it claims.

Duxfold ROCKS! I could spend a week there looking at planes

Only bad thing is they used a Buick engine to start the plane...they should have used a MOPAR engine

I used to guard two SRs when I was in Mildenhall England 87 & 88 (and NEACP) and occasionally got to speak with the pilots. Very interesting people. They commonly stored the pair in a C-141 hanger.
They were decommissioned shortly after that. What a shame.

It rained underneath them when they fueled them before talk off.  
Back in the day people smoked around them during and after they were refueled.
Awesome aircraft.

Loved sitting at the end of the runway and watch them take off at night.

Shortly before it was retired it made a run from LA to NY in 45 minutes.
To this day I don't think anyone knows its true top speed, even the pilots that flew it.

  thanks for the infomation guys ..good read & intresting facts

[Ghoste]

Leak when parked huh; kind of like old Harleys and big block Mopars then?

Here are some more classic military photos for ya'll.  Enjoy.

I saw the one in Huntsville, AL a few years back.  Very cool.

first model i ever did was a blackbird

[Silver R/T]

Interesting planes, pretty cool

We've got one here in Oregon, under the wing of the Spruce Goose (or was the last time I saw it): http://www.dodgecharger.com/forum/index.php/topic,3586.0.html

Last time I was there, the Strategic Air Command (SAC) Museum in Omaha has one suspended from the ceiling right at the entrance.

Love those planes.  Satellites were what did her in.

Hey, I used to live there.  My Father was stationed at NEACP and flew with the Blue Eagle team(Nightwatch E-4B).  Graduated from Bellevue West High School in 1984.

Can't attach picture since there's too many of them.

Back in 75 (I think; an F-15 Eagle prototype was there if that dates it...) I was at the Farnborough Air Show in England, when an SR-71 was due to visit from the USA. An announcement was made on the tannoy that it's arrival was imminent. Nothing happened for a couple of minutes, and then another announcement was made that it had missed England and and was turning round over Norway to come back. It arrived about five minutes later!
