*Bypass ratio is used only to estimate engine acceleration time. The effect of bypass ratio on engine efficiency is already included in the TSFC value. Feel free to set this parameter (even for turbojets) to whatever value gives a desired spool-up rate. Default value is 0. | *Bypass ratio is used only to estimate engine acceleration time.
