Early jet engines had narrow inlets and were very noisy, but as the diameter of the fans at the front increased, the engines became quieter.
早期的喷气式发动机进气口狭窄且噪音巨大但是随着前部风扇直径的增大发动机变得越来越安静。

In a reversal of current design trends the MIT concept increases the bypass ratio by minimizing expansion of the overall diameter of the engine and shrinking the diameter of the jet exhaust instead.
