Pratt & Whitney J58

Above Mach 2.2, some of the airflow is bled from the fourth stage of the compressor and dumped into the augmentor inlet through six bleed-bypass tubes, circumventing the core of the engine and transitioning the propulsive cycle from a pure turbojet to a turbo-ramjet. At Mach 3.2 cruise the inlet system itself actually provided 80 percent of the thrust and the engine only 20 percent, making the J58 in reality a turbo-ramjet engine.

Теперь еще раз глядим на картинку, смотрим на "стравливающе-обводные трубы" - и вроде понятно.

Все предельно понятно, только где они тут прямоточный двигатель увидели, это мне не понятно.
