I would have to do a test bench experiment to see if the thrust generating flow would come down the sides of the top section of an Airport shell without detaching. Flow director fins might have to be added to convert spiral flow to downward flow, or maybe they could be hidden in the propulsion shroud mounted topside. I have no such flow test equipment or know-how....yet! [
