Hanriot H.180
The Hanriot H.170, H.180, and H.190 were a family of light utility aircraft produced in France in the 1930s. All introduced in 1934, they appeared side by side at the Paris Air Show that year, the model numbers distinguishing between versions powered by Salmson, Renault, and Régnier engines respectively. Design and development In basic construction, the different variants were otherwise almost identical, as largely conventional monoplanes with high, strut-braced wings and fixed, tailskid undercarriage. The pilot and one or two passengers sat in an extensively-glazed, enclosed cabin. Although usually described as a monoplane, this family of aircraft all featured small, stub wings at the bottom of the fuselage. These carried the fuel tanks and served as a mounting point for the wing struts and undercarriage. An interesting feature was that the upper portion of the rear fuselage was a removable module, allowing it to be replaced with alternative modules for different roles, for example to carry a stretcher, or a second, open cockpit for pilot or gunnery training. Operational history The H.182 was the major production version, accounting for 346 out of the total of 392 aircraft built. Most of these were produced as part of a government order for
