Every now and then a question or idea hits me. Unless you just hang a EDF (Electric Ducted Fan) unit off the wings of your plane, even making what appears to be a modern commercial Bypass Jet, most EDF's are inside after a long tube mounted at the aft of the plane. In this way your basic EDF air chamber looks like a mini-wind tunnel.
Other than the EDF air chamber NOT having a TEST SECTION, I've never seen anyone put a HONEYCOMB-SCREEN-AIR STRAIGHTENER inside the PLENUM of an EDF system. Wouldn't using some type of AIR STRAIGHTENER, even scrunching a bunch of plastic straws inside the throat of the AIR CHAMBER just past the INLET allow the EDF unit to operate more efficiently working with NON-TURBULENT AIR? Or would the AIR-STRAIGHTENER cause too much drag?
