| Originally
designed by Pratt & Whitney to power a projected Navy aircraft,
the J58 eventually powered the SR-71 Blackbird. This
engine was a turbo-ramjet, with the turbine being largely bypassed
at high speed.
The J58 is also known as the JT11B.
The earliest flight I can find is on a A-12 in 1962. |
