Hanriot · France · first flew 1925 · fighter
The Hanriot H.31 was a single-engined, single-seat French biplane fighter built in 1925 to compete in a government programme. It was not successful and only one prototype was completed.
Recognition (WEFT)
| W — Wings | Mid-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | Close-cowled Salmson 18Cm engine with an Andre radiator under the fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Single-bay biplane with straight-edged parallel-chord wings
- Single wide-chord airfoil-section interplane strut on each side
- Close-cowled Salmson 18Cm engine with an Andre radiator under the fuselage
The wings have slight sweep and essentially no stagger, with a slightly smaller lower wing. The H.31 also has a forward full-chord slot between the upper wings.
Specifications
- The Hanriot H.31 has a length of 7.58 m (25 ft).
- It has a wingspan of 12 m (39 ft).
- Its maximum speed is 260 km/h (162 mph).
- Typical crew: 1.

History
It was designed for the C1 fighter competition, which specified 300-370 kW (400-500 hp) engines. Hanriot chose a 370 kW Salmson 18Cm 18-cylinder double-row water-cooled radial.
Variants
Only one prototype was completed, in 1925.
Where you'll see it
The type was not successful and only the one prototype was completed. The 1923 call attracted an unusually large number of competing designs.
