Hanriot H.D.1

Hanriot H.D.1 - 1916
Hanriot H.D.1

This was one of the aircraft flown by Sous Lieutenant Willy Coppens of the 9e Escadrille circa May 1918. The aircraft is finished in a French five-color camouflage pattern. The upper surface of the tailplane was in dark blue and white stripes. All undersurfaces were aluminum doped. The thistle emblem of the 9e Escadrille was in white.

The Hanriot HD.1 was a French World War I single seat fighter. Rejected for service with French squadrons in favor of the SPAD S.7, the type was supplied to the Belgians and the Italians with whom it proved highly successful. 831 of a total production of about 1200 were in fact produced by Italian companies under licence.

The Hanriot company produced a series of pioneering monoplanes pre-war, but had settled down as a licence manufacturer, notably of Sopwith 1½ strutters, when the HD.1 was produced in 1916.

Hanriot HD-2

Hanriot HD-2, a U.S. Navy version on floats.

The Hanriot HD.2 was a fighter aircraft produced in France during the First World War. The design was based on that of the HD.1, but the HD.2 was a purpose-built floatplane. It made use of enlarged tail surfaces and shorter wingspans with greater area. Like its predecessor, though, it was a conventional single-bay biplane with staggered wings of unequal span. The prototype had a twin pontoon undercarriage, with a small third pontoon under the tail. The third pontoon was later discarded on production machines, though.

The HD.2 was developed specifically as an interceptor to defend flying boat bases, but soon was used as an escort fighter to protect French reconnaissance flying boats. The United States Navy also bought 10 examples with wheeled undercarriages, designated HD.2C.

Hanriot HD.3

Hanriot HD-3 - 1917
Hanriot HD.3

The Hanriot HD.3 was a two-seat fighter aircraft produced in France during World War One. Similar in appearance to a scaled-up HD.1, it was a conventional, single-bay biplane with staggered wings of equal span. The pilot and gunner sat in tandem, open cockpits and the main units of the fixed tailskid undercarriage were linked by a cross-axle. Short struts braced the fuselage sides to the lower wing.

Design development of a compact, well-proportioned two-seat fighter was initiated as the HD.3 in the autumn of 1917, and a prototype flew before the end of the year. Powered by the excellent new 260hp Salmson (Canton-Unne) 9Za radial, the HD.3 had an armament of two fixed synchronised 7.7mm Vickers guns and two 7.7mm Lewis guns on a flexible mounting for the aftfacing gunner. A preliminary order was placed on behalf of the Aviation miiitaire for 120 HD.3s in April 1918, the total subsequently being raised to 300 when it was also ordered for the Aviation maritime. Few HD.3s had been delivered, in fact, by the time of the Armistice, but at least 75 were completed for the Aviation miiitaire and a rather smaller quantity for the naval service. One example of the HD.3 was fitted with twin floats as the prototype of the HD.4, series production of which was frustrated by the Armistice, and a night fighter version was tested as the HD.3bis. This latter had mainplanes of thicker section, enlarged ailerons and a revised rudder.

Hanriot HD.6

Hanriot HD-6 - 1918
Hanriot HD-6 - 1918

Evolved in parallel with the HD.5 and of generally similar configuration, but larger and more powerful, the HD.6 two-seat fighter was powered by a 530hp Salmson 18Z two-row radial water-cooled engine. This was essentially two Salmson 9Z engines on a common crankcase and flight testing was delayed by difficulties with this experimental power plant, eventually commencing in the spring of 1919. Armament consisted of two synchronised 7.7mm Vickers guns for the pilot and three 7.7mm Lewis guns for the gunner, two on a rotating mount and one firing through a trap in the fuselage floor. The pilot, seated beneath a cut-out in the upper wing, was offered a singularly poor field of vision. Performance did not show a significant improvement over that of the more compact and simpler HD.3, and development was discontinued by the late summer of 1919.

Varients

HD.6.C 2: Enlarged two-seat fighter protoype, powered by a 530-hp (395-kW) Salmson 18Z radial piston engine. Only one was ever built, not demonstrating significantly better performance than the HD.3.

Hanriot HD-7 - 1918

The Hanriot HD.7 was a French single-seat fighter prototype based largely on the Hanriot HD.3, using the wings and tail surfaces from the earlier model.

The aircraft was designed to replace the SPAD S.XIII fighter. However, after its first flight in 1918, it was found to be of good performance, but inferior to its main competitor, the Nieuport-Delage NiD 29, which then entered service production for the Aéronautique Militaire in 1918. No further production occurred.

Hanriot HD-9.Ap 1 - 1918

A single-seat reconnaissance fighter derived from the two-seat HD.3, the HD.9 was placed in the broad category of Avions de Corps d'Armee (thus being the HD.9 Apl) and its armament consisted of a single synchronised 7.7mm Vickers machine gun. The airframe was basically that of the HD.3 and the installation of the 260hp Salmson 9Z radial engine was identical, but fuel capacity was considerably increased. The first example of the HD.9 was completed in November 1918 as the initial aircraft built against an order for 10 machines. However, its career was cut short by the Armistice and there is no evidence that all nine remaining aircraft were completed.
