Why Are Aircraft Engines Getting Larger?

The size of aircraft engines is increasing day by day. Before small and large number of engines While there were, nowadays we can encounter huge ones.

The reason, of course, is for the benefit of airplanes. Why airplane engines are getting bigger and bigger Read on to find out!

For a certain fuel consumption, thrust power significantly determines the efficiency of the aircraft engine.

An engine’s bypass ratio is the amount of air passing through the engine’s core versus the amount of air circulating around the engine’s core and pushed out from the back of the engine by the large fan at the front. is the amount of air. After the production of jet engines, manufacturers tried to increase the bypass ratio.

In the core of the engine igniting compressed air with fuel Jet engines rotate the fan blades at the front of the engine with the energy obtained from this combustion. Some of the exhaust is also expelled to produce thrust. The faster and more efficiently the rotating parts at the front of the engine, which produce most of the thrust, spin, the more power it produces.

Larger engines can accommodate higher bypass ratios.

Aeronautical engineers, engines while keeping the combustion core smaller increased the size of the engines for larger fan blades and higher bypass ratios. This allowed more air to pass through the engine’s large fan blades before the fuel ignited.

Since there is less air in the core of the engine and the fuel will mix less, a significant amount of fuel savings is achieved. In short, more airflow was achieved from larger fan blades without the need to burn more fuel. Currently, the engine with the highest bypass ratio is Prat&Whitney 1000G’nin.
