Shhh...quiet please

I have been searching for a nice decent picture of the chevrons on the engine exhaust ducts for the Boeing Quiet Technology Demonstrator (QTD) 2. I finally found it at the 777-200LR Flight Test Journal.

The Boeing Flight Test team talks about their involvement in the program together with General Electric, Goodrich, ANA and NASA. In this article, they will be focusing on the testing methodology used.
