Based on comparison with results from experiments, an evaluation was performed of a method used to calculate the spanwise lift distribution on wings immersed in propulsive jets. Modifications of the original method were investigated. It is found that the method gives satisfactory results for an unflapped wing. However, even at a relatively small flap deflection the jet-induced effects are strongly underrated. The discrepancies can be reduced somewhat by adopting an improved wing model. It is concluded that this approach has a fundamental weakness, which must be input to the rigid jet model. The result is that basic features of the wing jet interaction, such as jet mixing and deformation, cannot be accounted for.
