configuration but unsatisfactory for the swept-wing configuration.
Subsequent to completion of this investigation, information supplied by
the contractor indicated that the XF1OF-1 airplane was to be equipped
with full-span slats, and, inasmuch as analysis indicated a possible
favorable effect of slats for the XF10OF-1 design, supplementary model
tests were performed for the swept-wing version to evaluate their effect.
