Why turbofan engine needs High bypass ratio? 點解要high bypass ratio?
Force = mass x acceleration [Ref Turbofan Engine | SKYbrary Aviation Safety] High bypass engines usually have a single stage fan which generates a high volume but relatively low speed air stream. The fan airflow, referred to as the cold air stream, is accelerated by the fan and passes through the engine remaining outside of
