The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds. Because of the wide speed range of the aircraft, the engine needed two modes of operation to take it from stationary on the ground to 2,000 mph (3,200 km/h) at altitude. It was a conventional afterburning turbojet for take-off and acceleration to Mach 2 and then used permanent compressor bleed to the afterburner above Mach 2. The way the engine worked at cruise led it to be described as "acting like a turboramjet". It has also been described as a turboramjet based on incorrect statements describing

  • Pratt & Whitney J58 (firemní označení JT11) byl americký proudový motor používaný na letounu Lockheed A-12 a následně na letounech YF-12 a SR-71. J58 byl jednohřídelový proudový motor vybavený přídavným spalováním určený pro činnost v extrémních podmínkách, rychlostech a letových hladinách. (cs)
  • Das Pratt & Whitney J58 (zivile Bezeichnung Pratt & Whitney JT11) ist ein Turbostrahltriebwerk des US-amerikanischen Herstellers Pratt & Whitney. Es wurde speziell für den Antrieb der Lockheed A-12 und deren Nachfolger Lockheed SR-71 für eine Geschwindigkeit bis Mach 3,2 entwickelt. Neben dem Turbostrahlbetrieb arbeitet es bei hohen Geschwindigkeiten auch als Staustrahltriebwerk, da über sechs Rohre, die ein einzigartiges Erkennungsmerkmal darstellen, Luft um die Turbojet-Stufe herumgeführt wird und direkt in den Nachbrenner gelangt.

  • El Pratt & Whitney J58 (designado por la empresa como JT11D) fue un motor de reacción utilizado en los aviones Lockheed A-12, y posteriormente en el YF-12 y SR-71 Blackbird. El J58 era un motor de ciclo variable que funcionó como un turborreactor y un sangrado para asistir al estatorreactor. El J58 era un motor turborreactor de un solo eje (single-spool) y una cámara de postcombustión.​ (es)
  • Pratt & Whitney J58-P4 (penunjukan perusahaan: JT11D) - adalah sebuah mesin turbojet siklus variabel, yang digunakan pada Lockheed A-12, dan kemudian pada YF-12 dan SR-71 Blackbird. Mesin ini pada dasarnya adalah hibrida dari turbojet dan mesin ramjet. (in)
  • Le Pratt & Whitney J58 (ou JT11) est un moteur à réaction conçu pour propulser les avions à hautes performances Lockheed A-12 Oxcart et Lockheed SR-71 Blackbird. C'est le premier réacteur au monde capable de maintenir la postcombustion pendant de longues durées, et le premier réacteur américain qualifié pour une vitesse supérieure à Mach 3. (fr)
  • プラット&ホイットニー J58(JT11Dとしても知られる)はロッキードYF-12とSR-71、A-12に搭載されたジェットエンジンである。本質的には可変バイパス比のアフターバーナーを備えたターボジェットエンジンである。 (ja)
  • Il Pratt & Whitney JT11D (o J58 secondo la nomenclatura delle United States Armed Forces) era un motore aeronautico a ciclo variabile sviluppato dalla Pratt & Whitney ed utilizzato sui Lockheed A-12, SR-71 e YF-12. Si trattava di un autoturboreattore, sorta di ibrido tra un motore a turbogetto ed uno statoreattore. (it)
  • Pratt & Whitney J58-P4 (обозначение компании JT11D) — турбореактивный двигатель изменяемого цикла, который использовался на военных самолётах-разведчиках Lockheed A-12, и, впоследствии, на и на SR-71 Blackbird. Является гибридом турбореактивного двигателя и прямоточного воздушно-реактивного двигателя. (ru)
