A note on the potential contribution of wing-body interference drag to the total drag of an aircraft
Published online by Cambridge University Press: 04 July 2016
Summary
The implications of a rise in the pressure drag of a wing near its junction with a fuselage are examined. Based on some data measured for a swept-wing-plate junction, in which the wing was of NACA 0015-profile normal to its leading edge and swept back at 20°, it is found that there is a potential penalty of order 1% of the total aircraft drag in the cruise condition.
