Description
In 1933, Avions Hanriot company designed the prototype of figher plane to compete in the STAé (Service Technique de l'Aéronautique or Technical Section of Aeronautics) C1 (single seat Chasseur of fighter) programme. The plane began flight testing in April 1933. Tested against its smaller and lighter competitors, it proved slower and less manoeuvrable and was returned to designer company for modification. It flew in April 1934 as the H.115, with its engine uprated, a new four-blade propeller with variable-pitch and a revised nacelle, shortened forward of the cockpit. With its new engine and propeller the H.115 was quicker than the earlier version, with a top speed of 390 km/h. After more modifications over the winter of 1934-5 it returned to Villacoublay in June 1935 and was officially flight tested until mid August, but failed to attract a contract because of its obsolescence.
