HISTORY



Detailing the development and operational history of the Hanriot HD.8 Single-Seat, Single-Engine Fighter Prototype.  Entry last updated on 1/29/2019. Authored by Staff Writer. Content ©www.MilitaryFactory.com.
The HD.8 was a single-seat, single-engine biplane fighter prototype drawn up by the Hanriot concern of France during the World War 1 period (1914-1918). It was used in conjunction with the new Le Rhone 9R series 9-cylinder, air-cooled rotary engine of 180 horsepower which resulted in only a single example of this aircraft being completed largely due to issues with the experimental powerplant. Flight testing of the completed form was had from March to April of 1918 - 1918 being the last year of the war. However, the troublesome engine never proved itself satisfactory which, in turn, resulted in an official end of the program.

As completed (and flown), the aircraft borrowed established biplane fighter qualities of pervious Hanriot designs that began with the HD.1 of June 1916 and evolved through the capable HD.3 of June 1917. A biplane wing configuration was used with the sole pilot positioned under and aft of the upper wing member. The engine drove a two-bladed propeller unit at the nose in typical fashion and a traditional tail-dragger undercarriage configuration was used for ground-running. Dimensions included an overall length of 20.1 feet and wingspan of 31.5 feet. Empty weight was 1,060lb against an MTOW of 1,520lb.

With its Le Rhone engine, the aircraft was tested at speeds reaching 125 miles-per-hour and could stay aloft for some two hours on internal fuel.
