, 2014 The aim pursued by this project is to show the design of a complete turbofan. Because this design process is very complex and large groups of engineers for their development typically need the scope thereof in a final project is very limited. However, attempts to give an overview of what this design process and show the way forward from the work done ...

Gaseous exhaust emissions from a JT8D-109 turbofan engine at simulated cruise flight conditions [PDF]
Gaseous emissions from a JT8D-109 turbofan engine were measured in an altitude facility at four simulated cruise flight conditions: Mach 0.8 at altitudes of 9.1, 10, 7, and 12.2 km and Mach 0.9 at 10.7 km.
