Abstract
An arrangement to mask direct view of the discharge end of a turbine through an exhaust duct extending downstream from the turbine. The turbine has an annular outlet. Two annular rows of fixed vanes are mounted in the outlet, one immediately upstream of the other. The two sets of vanes are reversely cambered so that the overall turning effect is insignificant and they are so located that each set of vanes blocks sight of the turbine through the gaps between the vanes of the other set.
