What type of engine is the J58?
Turbojet Engine
Pratt & Whitney J58 (JT11D-20) Turbojet Engine. Pratt & Whitney designed this engine for continuous operation at high Mach number flight with compressor inlet temperatures above 400 degrees C (750 degrees F). Development began about 1958, and production began in 1964.
Who made the J58 engine?
Pratt & Whitney
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….Pratt & Whitney J58.

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.
What is the most powerful aircraft engine?
GE90-115B
GE90-115B – 115,300lbf GE90-115B, a high-thrust variant of GE90 from GE Aviation, generates up to 115,300lb thrust at sea level making it the world’s most powerful commercial jet engine. The GE90 was developed specifically for the Boeing 777 series and over 1,000 engines are in service with Boeing.
What is the fastest airplane?
Lockheed SR-71 Blackbird
The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner.
How much thrust does a J58 have?
The J58 generated a maximum thrust of 32,500 pounds — more than 160,000 shaft horsepower — and was the most powerful air-breathing aircraft engine yet devised.
What engines do the 777 use?
The GE90 engine family powers all Boeing 777 models. It is the exclusive powerplant on the Boeing 777-300ER, -200LR, and Freighter. The engine has accumulated nearly 100 million flight hours and 14 million cycles since entering service.
How powerful is a 777 engine?
A Single Boeing 777 Engine Delivers Twice the Horsepower of All the Titanic’s. The RMS Titanic weighed almost 50,000 tons and could carry 3,500 people. Before it sunk, it was world-famous as the massive titan of the sea. Its multiple engines, powered by 159 coal furnaces, were designed to deliver 46,000 horsepower.
Which is the fastest vehicle on earth?
Fastest Cars In The World
- Hennessey Venom F5: 301 MPH. The Venom F5 boasts an exciting claimed a top speed of 301 mph, which knocks the previous top-speed figure by more than a school zone speed limit.
- Koenigsegg Agera RS: 278 MPH.
- Hennessey Venom GT: 270MPH.
- Bugatti Chiron: 261 MPH.
- Bugatti Veyron Super Sport: 268 MPH.
What was the maximum thrust of the J58 engine?
The J58 generated a maximum thrust of 32,500 pounds — more than 160,000 shaft horsepower — and was the most powerful air-breathing aircraft engine yet devised. Taken at Beale Air Force Base (AFB) in 1986, the impressive video in this post features the test of SR-71 J58 engine at max afterburner power.
When did the Pratt and Whitney J58 engine come out?
The J58 (also JT11D-20A but NOT J-58) engine was developed in the 1950s by Pratt and Whitney Aircraft Division of United Aircraft Corporation to meet a U.S. Navy requirement. The engine was designed to operate for extended speeds of Mach 3+ and at altitudes of more than 80,000 ft.
How did the J58 engine change to a ramjet?
The recover bleed solution extended the capability of the original J58 to M3+ converting the engine into a partial ramjet. Turboramjet engines have a transition from turbojet mode to ramjet mode as thrust-producing flow is transferred from the high pressure inner part to the low pressure outer part. [12]
Where was the SR-71 Blackbird J58 engine tested?
Taken at Beale Air Force Base (AFB) in 1986, the impressive video in this post features the test of SR-71 J58 engine at max afterburner power. This engine run was performed by MSgt John Wiltison.
