Greatest single engineering achievement in non-spacing faring, aviation history.
The love the fact that in THEORY, the SR71 had no speed limit. According to Kelly Johnson. |

The engines alone can cost $10,000 to $15,000 (each) and require regular manufacturer overhauls.
Speed is easily in excess of 200 mph. Shit happens fast at those speeds. |

IIRC, the speed limit was based on the engines melting (or at least overheating). The cones that regulate flow into the engine, even when fully closed at high speeds, could bleed through more air then the engines could handle. The airframe itself was probably nowhere near its limits. |

According to Kelly Johnson. if it works in theory, it works in practice, in theory. In practice, there was the one Blackbird (I can't recall if it was a A-12 or and SR-71)that had undergone maintenance and the blow-in doors on the rear of the engines were disabled in the CLOSED position. In flight a massive amount of air that would have normally been vented out those doors went out the exhaust, becoming part of the afterburner flow. Plus there was a massive reduction in drag due to no airflow disruption from the airflow coming out of the doors if they'd been allowed to open.. The pilot reported that the aircraft accelerated "like a scalded dog" compared to regular Blackbirds he'd flown. That resulted in the aircraft accelerating to a speed beyond the thermal rating of the Blackbird, which damaged a lot of systems on the aircraft. Lockheed said the pilot was lucky to be able to catch the situation before so much damage occurred that the airframe failed. After analyzing the event Kelly Johnson said he'd never realized how much faster he could have made the Blackbird by eliminating the blow in doors, but the thermal issues might have never been solvable with technology of the day. But I wonder if there weren't some tests down towards the end of the SR's career to see what could have been obtained. The quickly hushed-up story in the LA Times back in the 1980s about Lockheed flying a manned aircraft at 3,000mph had to come from somewhere. |

I think of all modern jets this is one of my favorites. It was amazing as far as capabilities go for something built in the 60's. |

Remember reading about them doing some closing rate tests. Like firing a 30.06 at each end of the range and timing it to get the bullets to pass close by in the middle of the range.
At 2100 mph (~ mach3) that's 3000 feet per second. |

From what I've read, the materials used in the SR71 still stand today as extraordinarily advanced in terms of thermal capabilities. We're talking nominal temperatures nearing a thousand degrees. Now, at higher altitudes the heating becomes less and less of a problem, but there's also less air to breathe. |

Now, at higher altitudes the heating becomes less and less of a problem, but there's also less air to breathe. The issues were more to do with non-structural portions of the aircraft getting too hot and starting to melt. A titanium airframe full of wiring with burning insulation, melting hydraulic system components and fuel used for thermal cooling that is ready to explode from excessive heat is not a good situation. That's what was the case with the overspeeded Blackbird. |

They weren't turbofan, they weren't turbojet. They were turboramjet.
