If you look at all of the pictures at the link provided it's definitely not a hovercraft. It has a round leading edge and a sharp, relatively speaking, trailing edge. It hasan airfoil shape in cross section and has the fences on the leading edge in order to prevent span wise flow. It also doesn't have anyway to blow air under it and it doesn't have a skirt.Arjen said:That looks very much like a hovercraft.
The outer wing panels look to be removable or foldable (for trailer carriage?) so putting the main landing gear in the panels would make life more difficult. Plus you do save some in weight and cost (if you consider cost as an independent variable). The large number of fences on the leading edge would indicate that there were some spanwise airflow problems - I had always wondered why Zimmerman chose a straight leading edge for the V-173 and XF5U - this might be a hint why!Sundog said:What I don't understand is the choice of the bicycle under carriage. In an aircraft like this it isn't going to save you much in weight and lower the drag much for what you're going to sacrifice in ground handling and take-off and landing characteristics.
