Hurel-Dubois HD.10
Hurel-Dubois · France · first flew 1948 · light aircraft
The Hurel-Dubois HD.10 was a French research aircraft built to investigate Maurice Hurel's ideas about high aspect ratio wings. It was a single-seat monoplane of metal construction.
Recognition (WEFT)
| W — Wings | High-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | 5.15 m fuselage |
| T — Tail | Twin fin |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Very high aspect-ratio wing of 32.5:1 mounted above the cockpit and braced by single lift struts
- Twin tail
- Retractable tricycle undercarriage
The metal wing carried Fowler flaps, and the fuselage was fabric-covered steel tube with the pilot in an enclosed cockpit under the wing trailing edge.
Specifications
- The Hurel-Dubois HD.10 has a length of 5.15 m (17 ft).
- It has a wingspan of 12 m (39 ft).
- Its maximum speed is 250 km/h (155 mph).
- Typical crew: 1.

History
Hurel set up the Société des Avions Hurel-Dubois with Léon-Joseph Dubois in November 1947, and designed the HD.10 as a prototype to demonstrate the practicality of his ideas. It made its first flight on 25 August 1948 with Hurel at the controls.
Variants
Only one was built. It was first powered by a 40 hp Mathis engine, which proved underpowered, and was re-engined with a 75 hp Praga D.
Where you'll see it
Testing at the Centre d'Essais en Vol led to enlarged vertical tail surfaces. The HD.10 made its final flight on 20 June 1954 after more than 218 flight hours and is preserved in the Musée de l'Air at Paris-Le Bourget.
