This is the second generation of the turbofan engine for aircraft, also known as the turbofan. This model includes the main body of the engine (the bypass and core) and the separately assembled tail nozzle. This work was made by a primary school student, please understand that the technical aspects may not be perfect. It is free to use, and you are welcome to modify and adapt it. The complex internal structure and fans are not included, only the engine outline. I know my work is much simpler compared to those made by professionals, but if you would like to, please click the download button. This would be a great help to me. Thank you again!
