The 747 is a four-engined jet aircraft, initially powered by Pratt & Whitney JT9D turbofan engines, then General Electric CF6 and Rolls-Royce RB211 engines for the original variants. With a ten-abreast economy seating, it typically accommodates 366 passengers in three travel classes.

The JT9D-3, the earliest certified version of the engine, weighed 8,470 lb (3,840 kg) and produced 43,500 lbf (193 kN) thrust. [7] Pratt & Whitney faced difficulties with the JT9D design during the Boeing 747 test program.

Oct 14, 2023 · The sheer size and weight of the B747 meant that even with its four engines and combined thrust of 192,000 lbs it could only take off and land at airports that had plenty of runway.

Nov 15, 2023 · However, on average, a typical 747 engine generates around 60,000 to 70,000 pounds of thrust per engine. It’s important to note that a Boeing 747 has four engines, meaning that the total combined thrust for the entire aircraft can range from 240,000 to 280,000 pounds.

The Boeing 747-400 is a development of the Boeing 747-300 with a slightly increased wing span and winglets, with more powerful engines and a two man crew cockpit. The engine options are: Pratt and Whitney PW4000, General Electric CF6-80C2B1F/B5F or Rolls-Royce RB211-524G2-19/G3-19/H2-19/G2-T-19/G3-T-19/H2-T-19. Mmo (max. Mach) max. Takeoff Weight.

Cockpit crew: 3 (captain, first officer, flight engineer). (...)

May 20, 2024 · A Boeing 747 typically produces around 63,300 pounds of thrust per engine, with four engines on the aircraft. Therefore, the total thrust produced by a Boeing 747 is approximately 253,200...

Engine thrust has grown from 43,500 pounds (19,730 kg) per engine on the early 747s to as much as 63,300 pounds (28,710 kg) on the current model. The diameter of the 747 engine cowling is 8 feet 6 inches (2.6 m).

Boeing used a new method of spotting potential hazards known as "fault tree analysis," where engineers could easily see the impact of a failure of one part or system on other parts. The 747 became the first airplane to use this accurate method of forecasting possible trouble.

There are three engine options for the 747-400: the CF6-80C2B1F rated at 56,700lbs thrust; the PW4056 rated at 56,000lbs thrust; and the RB211-524G/H and -524G/H-T rated at 58,000lbs and 60,600lbs thrust respectively.
