Hanriot H.41

Summary

The Hanriot H.41 was a military trainer aircraft produced in France in the 1920s. It was a further development in the family of aircraft that had commenced with the HD.14 in 1920, and incorporated a number of design features that had been developed for other members of that family. Like those other aircraft, however, it was a conventional, two-bay biplane with unstaggered wings of equal span.

H.41
Role Trainer
National origin France
Manufacturer Hanriot
First flight 1925

The H.41 used the modern engine and mixed construction developed for the HD.40 air ambulance and used them in a new design for a military trainer. The design did not prove a success, however, and only eleven were built, with three different engine types. A floatplane variant based on the HD.17 was slightly more successful, with twelve examples exported to Greece and Portugal.
