Abstract: A vortex suppressing flow eductor apparatus having a vortex filament producing flow eductor is provided with corresponding vortex destroying plates positioned and extending sufficiently downstream from a point within educted flow and deep enough into the vortex filament so as to essentially destroy the vortex filament. A particular embodiment provides a freestream sensor scoop, for use in an aircraft gas turbine engine inlet, having an eductor diffusing channel and a fairing surrounding a forward portion of the diffusing channel. A sensor supporting mast is provided for helping to measure freestream air characteristics. Vortex destroying plates are provided for suppressing vortex filaments generated by the channel, fairing, and mast.
