 Abstract

A scheme is described by means of which the 12-inch fan-in-wing model in the Engine Laboratory was separated from a mechanically connected effluxremoving duct. The modifications that were introduced included a slotted bellmouth inlet, which served as a catch-flow entrance below the air gap, and a diffuser at the exit of the ducting system, which corrected the static pressure level in the duct for transmission of the full efflux flow. The modifications were intended to facilitate mechanical isolation of the model so that direct lift measurements could be made while the efflux air was removed with essentially zero ground effect.
