HOLY CHIT! That thing is glowing RED HOT! Beautiful pic. Thanks guys for the conversation! I love this forum.
Not the only one that glowed red hot in operation. Here's a shot of a GE4 in a test cell. It was supposed to push the Boeing SST at Mach 2.7 cruise and it produced 70,000lbs thrust on the test stand. To this day the most powerful afterburning engine built. |

It was 5 feet in diameter and 25 feet long so probably not.  |

| Well, GE90s produce over 80k...course 80% of that comes from the fan. |

The -115 produces over 123k But then it's a LOT bigger in diameter than the GE4. Biggest afterburning engine I ever heard of was a notional one designed for a NASA flyback booster at 105,000lbs thrust. I wonder how powerful of an engine they could produce if they made an afterburning engine based on the GE90 core? Back to the GE4 for a moment though, to put it in perspective the engines on the Blackjack only put out 55k by comparison. |

Wouldn't work with the current design. The amount of back-pressure caused by the augmentor would most likely cause that huge fan to stall. If it didn't stall, the turbine would be very overworked, and the Core of the engine may not even make enough power to drive it.... IMO
The fuel consumption would be astronomical too. There would be so much fresh air flow in the augmentor the fuel flow would need to be equally proportioned.

| For those interested inBlackbird facts / info, see SR71webmaster site. Put together by Leland Haynes, former Crew Chief. Excellent for info, stories,lots of links. I was Crew Chief on the "C" model,#981 from '69- 73. |

Would that be "The Bastard" up at Hill AFB? Someone told me they heard someone left a wrench in the fuel tank that was never removed. Any idea if that's BS? |

| sferrin, 'yep thats her @ Hill AFB. She laid out in the dirt in pieces for a long time. Good to see her intact again. I stopped to see her a while back. Never heard the story about the wrench / fuel tank 'tho. Interesting story on how she came to be at all. |

Hi guys, for those in the UK, this is happening at Duxford on 8th March...
On 8 March come and meet under the wing of the Blackbird to hear a talk by Colonel Richard H Graham, US Air Force SR-71 squadron commander and former SR-71 pilot.
The 45-minute talk on the highest-flying and fastest jet aeroplane will include a short film, Kelly Johnson building the SR-71. It will then be followed by question-and-answer session and visitors will have the opportunity to purchase signed copies of Colonel Graham's new book, Flying the SR-71 Blackbird.
Also available for purchase on the day are Colonel Graham other publications, SR-71: The Secret Missions and SR-71 Revealed: The Inside Story.
The event will take place at 2.00pm at the American Air Museum, under the wing of the Blackbird SR-71.

| The more I think about the SR-71, the more it seems like something that would have been cancelled for being too ambitious or expensive. And yet it's real. Amazingly real. What other production aircraft can take off under its own power, cruise at over Mach 3.2 at over 80,000 feet without killing the engines, and land in one piece? The plane is quite a dragon. |

Well the A-12 program was dropped, and the YF-12 only saw 3 prototypes, shall we mention the M-21/D-21 combination that was abandoned? 
Of the 4 versions of the "Blackbird" produced, only one survived, entered service in numbers, and had a long career.
