The 747 is a quadjet aircraft that was first powered by Pratt & Whitney JT9D turbofan engines, which were later replaced by General Electric CF6 and Rolls-Royce RB211 engines for the first generation of 747 aircraft. It can generally carry 366 passengers in three different travel classes because to its ten-abreast economy seats.

Do all 747s have 4 engines?
Currently, the Boeing 747 is the only commercial airplane with four engines that is still in production. Other four-engine aircraft that may be seen are the Airbus A340 and the Airbus A380, which is a double-decker version of the A340. Because of their inefficiency, the number of these planes in service is expected to continue to drop over the next ten years.
Does a 747 have 5 engines?
Despite the fact that it was constructed several decades ago, it has kept up with the changes and helped to develop contemporary aviation. The Boeing 747 is distinguished by its capacity to fly with five engines, which is a first for commercial aircraft.
Why does a 747 have 5 engines?
The second engine increases the amount of drag on one side of the plane. As a result, pilots must make adjustments to the power on the other side in order to compensate. Because of the particular load, the aircraft was heavier than usual and had to make additional stops.
How powerful is a Boeing 747 engine?
In terms of horsepower per engine, the 747 and the Super Constellation are estimated to have 14 984 horsepower and 1646 horsepower, respectively, for their respective aircraft. The Wright 3350 turbocompound engines that drove the Lockheed aircraft are among the most powerful reciprocating engines ever designed for aviation usage, and they were used to power the Lockheed aircraft.
Can a 747 take off with 2 engines?
A 747 has only two engines, one on each side of the plane. A 757 is available for travel. A 747 cannot take off with just two engines because of the amount of time it would take to build up enough speed to do so. However, once in the air, it will continue to fly at its current speed.
Can a Boeing 747 fly on one engine?
Because only one of the B747’s engines can be utilized for takeoff, it would need two engines to convert the plane into a two-engine aircraft. One of the certification criteria for a multi-engine airplane is that it must be able to take off safely even if one of its engines fails.
Can a 747 fly on 3 engines?
The 747 has been certified to fly with three engines in order to reduce fuel consumption.
How much does a 747 engine cost?
The 747 aircraft’s engine, which costs roughly $12 million depending on the manufacturer, is the most expensive component. An airline will not be able to acquire an engine as long as there are less than two engines available for purchase. What is the price of a Boeing 737 jet engine?
|Aircraft model||Engine||New Price|
|Boeing 747-400||Pratt & Whitney, GE, ROLLS-ROYCE||$240M|
Do Boeing 747 still fly?
Fortunately, the 747 has always been a popular freighter, with both dedicated freighters and converted passenger aircraft remaining in service in considerable numbers. Aerostan and Kyrgyzstan Airlines are among the airlines that operate cargo variants of the 747.
How much does a decommissioned 747 cost?
Once a plane has been completely dismantled and stripped of all useable components, its metal frame is sold for scrap. The scrap value of a 747 might be as high as $55,000 in some cases.
Who makes the engines for Boeing 747?

What is the most powerful jet engine?
When tested, the GE9X engine for the Boeing 777X achieved a thrust of 134,300 lbs, earning it a place in the Guinness Book of World Records as the world’s most powerful commercial aircraft jet engine (test performance).
How much does a Boeing 747 cost to fuel?
A 747 can accommodate 380 to 560 passengers, depending on how the aircraft is configured by the operator. A fully stocked one is a moneymaker for the company. However, if an airline is unable to fill all of its seats, it must distribute the cost of 63,000 gallons of jet fuel — approximately $200,000 — among a smaller number of customers.
How heavy is a full 747?
To summarize, depending on the model, an empty Boeing 747 airplane weighs anything between 337,100 pounds (152.9 tons) and 485,300 pounds (220.1 tons) in terms of its operational weight when not loaded with passengers. Furthermore, its maximum take-off weight ranges between 700,000 pounds (320.0 tons) and 987,000 pounds (987,000 tons) (447.7 tons).
