Pulsating Wing to Drive Propless Plane

LACKING both propeller and tail assembly and driven only by a 10 H.P. motor, an Austrian plane is expected to take the air this summer. The motor drives a compressed air pump which expands and evacuates a large series of pneumatic air cells in the wings. It is planned that pulsations of these cells will furnish lift and driving power for the ship. By altering the stroke in the rear wing cells, which act as a propeller, the plane is expected to climb, bank, dive, hover and go forward or backward. The forward wing is used primarily for the higher speeds. The framework of the ship is constructed of welded steel tubing.

That's a nice and advanced idea.

The picture is a " fantasy " inspired by the the Raimund Nimführs " Swirrflüger " ( Austria) which was built in the thirties ,but was never finished .

Two pics from the excellent "Enzyklopädie Luftfahrtzeugbau in Österreich" by Reinhard Keimel-Aviatic Verlag 2003 :

Hi,


the Dr. Raimond Nimfyura made many patents for a variable geometry wing
aircraft,during the 1930s,he started to develop the Maholeta,it was a strange
ornithopter aircraft,powered by one 10 hp engine,but it was never completed.

It's Dr. Nimführ.

You must be very careful with documents from Russian or Ukrainian sources. These languages add suffixes to the names of people depending on their place in the sentence.

What an advanced design concept for the time! I really do like these unique design ideas that designers implemented and tested for some of their designs.
