Worked for Lockheed in the Skunkworks for 12 years, two of those on the SR-71. Great plane but hard to work on. Rest of the time on the U-2 so I have worked on the fastest and the highest aircraft. Also worked for a time on the space shuttle and B1-B and B-2.
There used to a Blackbird in the Cosmosphere in Hutchinson, KS. You could actually touch it.
The PW J58 engine itself is a marvel.
I saw one up close, and one of the old hands I was with worked on them when they were operational.
He said they leaked fuel like a sieve sitting on the ground, but once they got hot and were burning in the thin air, they tightened up and became super efficient.
When we (I work for P&W) were still running J58 engines on our test cells in Florida I would sometimes go watch, awesome at night since the entire engine glows. Once stood between test cells running a J58 at full afterburner and a cell running a F100-PW-229 at full afterburner. The noise and sensation throughout my body was unbelievable.
The story about the fuel leaks is true except that it was the airframe holding the fuel, not the engines. At altitude the titanium skin would expand and seal the leaks.[/QUOTE]
I had a buddy that was flight line fireman at the blackbird base in the UK. He said they had to "mist" the plane for awhile when it landed as the skin was so hot the pilots couldn't leave the aircraft until they did.
I didn't put a lot of stock in this story, but with what you guys are saying, maybe that was the truth?
