Evaluation of Levinsky's method for the calculation of the lift distribution on a wing in propulsive jets

Based on comparison with results from special experiments, an evaluation has been performed of the method of Levinsky, Thommen, Yager and Holland, which is intended to calcxilate the spanwise lift distribution on wings immersed in propulsive jets. Various modifications of the original method have been investigated. It was found that the method,...

Evaluation of a method for the prediction of jet-airframe interference

A brief description is given of a method, developed at NLR for the prediction of interference effects between (propulsion) jets and parts of airframes. The jet flow region is described by a model for a jet in a nonuniform mainflow, accounting for the presence of the airframe. The potential flow field around the airframe-jet combination is...
