Establishment of Lift on an Aerofoil with a Jet Flap: A Theoretical Note Relating to a Wing with Trailing Edge Jet with Extension to Cover Wings of Finite Span Available to Purchase

IN the two‐dimensional case the configuration shows a wake which forms a discontinuity in the flow, being bounded by contact vortices δγi1 and δγi2 which have as resultant a vortex δγi (FIG. 12). For there to be lift: δγi2<0, δγi1>0, δγi<0. There corresponds to each vortex δγi a vortex on the aerofoil δΓi of the same sign, and in addition a vortex Γ corresponding to the free stream potential, without jet.
