The wing of the Fairchild Republic A-10A twin-jet close-support airplane is opproximately rectongular with a wingspan (the length perpendicular to the flow direction) of

17.5m

and a chord (the length parallel to the flow direction) of

3m

. The airplane is flying at standerd sea level with a velocity of

240(m)/(s)

. If the flow is considered to be completely laminer, calculate the boundary layer thickness at the trailing edge and the total skin friction drag. Assume the wing is approximated by a flat plate. Assume incompressible flow.

The airplane is flying at standard sea level with a velocity of 240m/s. If the flow is considered to be completely laminar, calculate the boundary layer thickness ot the trailing edge and the total skin friction drag. Assume the wing is approximated by a flat plate. Assume incompressible flow. The boundary layer thickness ot the trailing edge is The total skin friction drag is cm. N
