Skin-friction measurements have been made on a half-model slender wing of 24 ft root chord at low subsonic speeds. The maximum root-chord Reynolds number was 30 x 10power6. The measurements were made using surface pitot-tubes ...

Equations have been derived for the velocities induced in an incompressible flow by distributions of infinite source and vortex lines representing wings of infinite span and constant chord having both sweep and dihedral. ...
