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,...

Experimental investigation of the aerodynamic characteristics of a wing propulsion jets

With the intent to test the qualities of the theoretical models used in two different calculation methods, pressure distributions have been measured on a simple half model wing-in-jet combination. The position of the jets relative to the wing was varied, mainly in a plane perpendicular to the span. Jet velocities of 1, 2 and 3 times the tunnel...
