These included Émile Dewoitine, Kurt Tank and Reimar Horten, the latter best known with his brother for their interest in tailless aircraft.

Clen Antú means Sun Ray in Mapudungun,[2] a language spoken in some areas of Argentina and Chile.

According to one source, the Clen Antú was intended as an aerodynamic model of a four-engined flying wing transport,[1] the I.Ae 38 Naranjero.

Broad chord tabbed control surfaces filled the trailing edge from the tip to about half-span and airbrakes were fitted.

The accommodation pod was narrow but tall, providing fully instrumented tandem dual control positions.

Aft of the cockpits the plywood pod ended in a flat oval shape which provided some yaw stability.

The pod continued below the wing containing a tandem pair of wheels with brakes at the rear and skids below the nose.
