It is found that the entrainment effect of a thin jet emerging from the leading
edge of a delta wing is sufficient to remove the secondary separation. The minimum
jet momentum required is small, but increases with incidence. Tests made without
blowing, and with minimal blowing, include balance measurements, pressure plotting
and tuft studies, over the range of incidence α = 0[degrees] - 20[degrees] . It is concluded that the
presence of the secondary separation does not affect the lift or the vortex height
appreciably, but is at least partly responsible for the large discrepancy between
theory and experiment with regard to the spanwise position of the vortex. |
