To give a sense of scale, each GEnx-2B67 engine on the Boeing 747-8 is capable of producing up to 66,500 pounds of thrust. This figure might vary slightly based on specific conditions like altitude, temperature, and the engine’s overall health. When you multiply this by the four engines on a 747, the total thrust available to the aircraft is a staggering 266,000 pounds. This immense power is necessary to lift the aircraft, which has a maximum takeoff weight of nearly 1 million pounds for the latest models.
The Boeing 747, affectionately known as the “Queen of the Skies,” has been a marvel of aviation engineering since its first flight in 1969. Central to its awe-inspiring capabilities is the power generated by its engines. For an aircraft of its size, understanding the torque produced by one of its engines involves delving into the complexities of jet engine mechanics and the remarkable engineering behind this iconic aircraft.
First, it’s essential to clarify that jet engines like those on the Boeing 747 are typically measured in terms of thrust, not torque. Torque is a concept more commonly applied to propeller-driven aircraft, where the engine’s rotational force is directly related to the propeller’s performance. In jet engines, however, the primary measurement is thrust, which is the force that propels the aircraft forward.
Each Boeing 747 is equipped with four engines. Over its various models, the 747 has been fitted with engines from three major manufacturers: Pratt & Whitney, Rolls-Royce, and General Electric. The most recent model, the 747-8, uses the GEnx-2B67 engine from General Electric. These engines are colossal in both size and power, capable of delivering an incredible amount of thrust.

This immense power is necessary to lift the aircraft, which has a maximum takeoff weight of nearly 1 million pounds for the latest models.
The design of these engines is a marvel of modern engineering. Jet engines work by drawing air in at the front with a fan, compressing it, mixing it with fuel igniting it, and then blasting it out the back. This process generates the thrust that propels the aircraft forward. The efficiency and power of these engines are what enable the 747 to achieve its long-range flights, such as the 15-hour non-stop journey from Sydney to Dallas.
In summary, while the concept of torque doesn’t directly apply to the jet engines of a Boeing 747, the thrust produced by these engines is a testament to the incredible advancements in aerospace engineering. Each engine on a 747 generates enough thrust to support the immense size and weight of this aircraft, enabling it to carry hundreds of passengers across vast distances with reliability and efficiency that have been refined over decades. The Boeing 747 remains a symbol of human ingenuity in conquering the skies, with its engines playing a central role in this remarkable feat.
