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.
Armament
ASSUMED:
2 x 7.7mm Vickers Machine Guns in fixed, forward-facing mountings over the nose synchronized to fire through the spinning propeller blades.
