Okay, to rephrase the question
1.) What is the L/D ratio of a DC-8 wing, and what percentage of the flow is laminar?
2.) What kind of percentage of the flow is laminar, theoretically speaking, on a plane that used small holes on the wing (including leading edges) with pumps to suck away the turbulent flow and artificially establish laminar flow at:
- Mach 0.8
- Mach 0.9
- Mach 2.0
- Mach 3.0
3.) What kind of percentage of the flow, hypothetically is laminar on a laminar-flow airfoil (one that does not use suction and small holes) designed for:
- Mach 0.8
- Mach 0.9
- Mach 2.0
- Mach 3.0
