This recent photo of ZM400 shows it fitted with a scabbed-on airflow deflector in front of the rear paratroop exit door.

Is this a new fitment on trial ??

I thought that the inner and outer props rotating in opposite directions was supposed to provide a benign airflow for paradropping ??

Maybe the airflow isn't as smooth as was expected ???

All I can say is that I have seen this since a long time. I am not sure but it might have been added before the reception test. But not all aircrafts might have been fitted with this in the same time.

I don't believe the deflector is related to the propwash.

One needs to break the fuselage laminar flow to prevent a jarring transition for jumpers. Best that they exit straight into turbulent air.

I'm sure a parachutist could provide some insight.

On a side note, what a fantastic picture of the almost biological wing and appendages on this aircraft!
