To build a stiff F18 you need to lower class weight. To build a stiff F16 you need to increase class weight.
Sure, I'm gullible.
No, you just struggle to understand the written word sometimes
To make it simple for you:-
F18 costs can come down with lower weight F16 costs can come down with higher weight
Whilst the above statements seem contradictory, it all makes sense when you apply logic, it doesn't take a degree in composite engineering to understand that there are weight/cost/stiffness implications if you are too far skewed with one of the three factors above.
