The Hurel-Dubois HD.10 was a French research aircraft first flown in 1948 to investigate Maurice Hurel's ideas about high aspect ratio wings. It was a single-seat monoplane with retractable tricycle undercarriage and twin tails, featuring a very high aspect-ratio wing of 32.5:1. This was mounted above the aircraft's enclosed cockpit and braced with struts. Construction was of metal throughout. Between 1948 and 1954, this aircraft accumulated some 218 hours 27 minutes of flight time and is now preserved in the Musée de l'Air et de l'Espace in Paris.
