Title: Hurel-Dubois HD32

The Hurel-Dubois HD.32 was an unusual French aircraft produced during the 1950’s to exploit Maurice Hurel’s ideas on extremely high aspect ratio wings. The French government sponsored the construction of two aircraft initially, one HD.31 with Wright engines and one HD.32 with Pratt & Whitney engines. The first example flew in December 1953, initially with twin tail fins. These were changed for a single fin, then both aircraft were converted to HD.321 configuration with different Wright engines.

A small production run of 8 survey aircraft known as the HD.34 was built for the French Institut Geographique Nationale and operated from Criel airfield North of Paris for 20 years until the late 1970’s. One example is still operated in France as an historic aircraft.
