Was 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.
Who designed the J58 engine?
Pratt & Whitney
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.
What plane has the most thrust?
The GE90-115B is powerful enough to fly GE’s Boeing 747-100 testbed with the other engines at idle, an attribute demonstrated during a flight test. According to the Guinness Book of Records, at 127,900 lbf (569 kN), the engine holds the record for the highest thrust (although rated at 115,300 lbf (513 kN)).
How does the Pratt and Whitney J58 work?
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.
What was unique about the afterburner on the SR-71?
The SR is the only airplane I know that required the use of afterburner to stay on the boom,” Brian Shul, former SR-71 Pilot. To allow it to stay connected and receive all 80,000 lbs of fuel, the pilot had to light one afterburner, the asymmetric thrust of which made the plane fly slightly sideways.
What plane has the highest power to weight?
The most powerful commercial airline jets with four engines, the Boeing 747–8 and Airbus A380 have a thrust-to-weight ratio much less than 1:1. The 747–8, with a total of (4 x 72,300 pounds of thrust) 289,200 pounds of thrust, has a maximum takeoff weight of 975,000 pounds.
Why are Rolls Royce engines named Trent?
In keeping with Rolls-Royce’s tradition of naming its jet engines after rivers, this engine is named after the River Trent in the Midlands of England.
