Measurements of Aerodynamic Derivatives on a Wing with a Series of Tip Bodies

摘要

Oscillatory aerodynamic lift and pitching-moment derivatives have been measured in a wind tunnel at low subsonic speeds on the following wing and wing-body combinations:n(i) tapered wing of aspect ratio 1.3, mid-chord line unswept, with a sharp leading edge, (ii) above wing fitted with a nacelle in three chordwise positions at the tip,n(iii) wing at (i) fitted with a tip body representing a tank or store, and tested with and without a fin at the rear of the body.
