WebIt is well known that the main purpose of the by-pass principle is to improve the propulsive efficiency of a simple jet engine by removing some of the energy left in the jet gases and … WebAug 16, 2024 · 1. Over most of the engine length, the bypass air travels at the same speed but is much faster than the core air entering the combustor. Let's assume a typical fan engine like the CFM56 pictured below. It starts with an intake which helps to equal flow … WebThis is because the power the engine produces is P = F v. So at high speed, larger part of the power output is the useful work moving the aircraft. In high-bypass engine the maximum power output of the fan is limited though (similar to propeller), so compared to a turbojet the difference in efficiency is higher at low speed.
