What planes used the J58 engine?

For extreme high-altitude and high-speed environment operation, the engine required special fuel and oil. Two J58 engines powered each Lockheed A-12 and YF-12 interceptor, and the SR-71 Blackbird reconnaissance and SR-71B trainer aircraft.

Is the J58 a ramjet?

The J58 was a one-of-a-kind engine. Its unique trick involved the ability to transition from turbojet engine to turbo-ramjet engine in flight, sucking in vast amounts of oxygen-rich air and burning it to drastically increase engine output. The J58 made the SR-71 the fastest air-breathing plane ever.

How reliable are modern jet engines?

Despite the tremendous engineering and tight tolerances involved in the design, a turbine/jet engine is very reliable. Turbines do not break down easily, and if they do, it is usually a supporting system that fails. A broken pump and a clogged pipe are much more likely than the turbine to malfunction.

What planes have Pratt and Whitney engines?

P&W engines can be found on the A220, the A320 family, A330, 747-400s, 767, and Embraer E-jets. In recent years, the manufacturer has seen its narrowbody aircraft engines do well and has been focusing on those.

What plane replaced the SR-71?

What type of engine is the Pratt & Whitney J58?

turbojet engine
The Pratt & Whitney J58 (company designation JT11D-20) was 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.

Has anything replaced the SR-71?

The high-speed SR-72 plane will replace the SR-71 Blackbird. The SR-72 aircraft will have the capability to perform high speed intelligence, surveillance and reconnaissance operations. Image courtesy of Lockheed Martin. First flight of the SR-72 demonstrator is anticipated in 2023.

What is the lifespan of a jet engine?

Older and smaller jet engines typically have TBOs of 5,000 hours at the most. More modern engines have about 6,000 hours or more.

Does Pratt and Whitney still make engines?

Today, over 7,000 Pratt & Whitney military engines are in service with 34 armed forces worldwide, setting new standards for performance and dependability. Pratt & Whitney is a world leader in the design and manufacture of next generation propulsion technology supporting both domestic and international partners.
