When functioning normally, the shock waves stay inside the inlet. If something disrupts this process, the engines lose their smooth airflow. The result of this means the jet can kick like a mule – or ...

Aerospace startup Hermeus announced it has started testing the Pratt & Whitney F100 engine that will power the Quarterhorse Mk 3 aircraft to Mach 5 ...

Back in 1976, at the height of the Cold War, one of America's most secretive planes, the SR-71 Blackbird, managed to achieve a tremendous feat: it traveled at a speed of Mach 3, which is 2,193.2 ...

The Lockheed D-21, a high-speed, high-altitude drone, was an unmanned variant of the illustrious SR-71 Blackbird. The ...

The infamous stealh jet, the SR-71 Blackbird needed powerful engines to stay off the radar and outrun anything. The J58 fit the bill perfectly.

Lockheed ’s SR-71, known informally as the Blackbird, first took flight in the mid-1960s. Powered by Pratt & Whitney J58 engines, it regularly soared above 80,000 feet.

The solution was to inject triethyl borane (TEB) into the SR-71’s engines—a complex and expensive procedure that boosted the complexity and the expenses of the overall project.

The original SR-71 could fly past Mach 3.0 thanks to its Pratt & Whitney turbojet engine. The J58 was uniquely designed to operate for longer periods of time using its afterburner.

The SR-71 used the same J58 engines as the A-12. The first flight of the SR-71 was in December 1964, and a total of thirty-two aircraft were built, with twelve lost to accidents and none to enemy ...
