Question

The engines are considered "high bypass turbofans", which makes them extremely efficient. Approximately what percent of air is actually being bypassed around the core?

Answer 1

In high bypass turbofan engines, around 85-90% of air is actually being bypassed around the core.

Step-by-step explanation:

In high bypass turbofan engines, a significant amount of air is bypassed around the core. This bypassed air helps in improving the engine's efficiency. The exact percentage of air being bypassed depends on the design of the engine, but typically it can be around 85-90%.
