Nieuport-Delage NiD 29 explained

The Nieuport-Delage NiD.29 was a French single-seat biplane fighter (C.I category)[1] designed and built by Nieuport-Delage for the French Air Force.

Design and development

The prototype NiD.29 was an equal-span biplane with ailerons on both upper and lower wings. It had a fixed tailskid landing gear, a nose-mounted engine and a single open cockpit for the pilot. The prototype NiD 29 was evaluated by the French Service Aeronautique de l'Armee in July 1918 and a pre-production batch was ordered on 21 August 1918. It was powered by a Hispano-Suiza 8Fb piston engine, it performed well in test but could not achieve the required ceiling. The second prototype was modified with an increased wingspan and on exceeding the required ceiling it was ordered into production in 1920, becoming the fastest service fighter in the world at that time. Production aircraft did not have ailerons on the upper wing and the lower wing ailerons were increased in span, but reduced in chord.

The first mass production deliveries were made in 1922 to the French Air Force and the type was popular although it did have a tendency to enter a flat spin. The French military bought 250 aircraft which were built by Nieuport and seven other companies. The NiD 29 was to become an important fighter in the 1920s with purchases of 30 by Spain (including 10 Spanish licence built aircraft), 108 by Belgium (87 licensed built by SABCA). The Italian Regia Aeronautica bought 175 aircraft including 95 built by Macchi as the Macchi-Nieuport 29 and 80 built by Caproni. Sweden bought nine aircraft and designated them J 2. The Japanese company Nakajima bought a pattern aircraft and built 608 for the Imperial Japanese Army as the Ko-4.

Racing versions of the aircraft were developed and they gained eight world speed records and won the 1920 Gordon Bennett Trophy and the 1922 Coupe Deutsch de la Meurthe competition.[2]

Operational history

Three NiD 29s were modified for reserve Captain Joseph Sadi-Lecointe in November 1925 and used on seventy sorties against insurgents in Morocco using bomb racks with six 10 kg bombs.[3] Spanish aircraft were also involved in similar operations in North Africa.

Variants

Nieuport Ni.29:Prototype for series, powered by a 320abbr=onNaNabbr=on Hispano-Suiza 8Fb engine.
  • NiD.29 C.1
  • Production aircraft, powered by 320abbr=onNaNabbr=on Hispano-Suiza 8Fb engines.
    NiD.29 B.1
  • Small number of conversions as an experimental assault version to carry six 10abbr=onNaNabbr=on bombs.
    NiD.29bis
  • Prototype only with reduced wing area and steerable tailskid, powered by a 320abbr=onNaNabbr=on Hispano-Suiza 8Fb engine.
    NiD.29G
  • Prototypes fitted with a Gnome Monosoupape 9N rotary engine, two later converted to take a Hispano engine and fitted with twin floats and an auxiliary tail float for the Grand Prix de Monaco in 1923.
    NiD.29M
  • Single prototype for Aeronavale (M for Marine) similar to 29G but with 180abbr=onNaNabbr=on Le Rhone 9R, further converted into 32Rh.
    NiD.29D
  • Conversion with an engine driven supercharger for an attempt on the altitude record, reached 7000m (23,000feet).
    NiD.29 ET.1
  • Trainer variant with a 134kW Hispano-Suiza 8Ab engine and a single synchronised Vickers machine-gun, three built.
    NiD.29 SHV
  • Seaplane for the 1919 Schneider Trophy contest with reduced wingspan and military equipment removed, two aircraft built and one was also entered in the 1921 event but neither aircraft flew in the races. Powered by a 300abbr=onNaNabbr=on Hispano-Suiza 8Fb engine
    NiD.29V
  • Lightweight racer developed in 1919 with a wingspan reduced to 6.00m (19ft 8¼in), powered by a 320abbr=onNaNabbr=on Hispano-Suiza 8Fb engine, three built.
    NiD.29Vbis
  • One-off conversion with an enclosed cockpit to gain more speed, the pilot had small teardrop windows on each side with little forward visibility. Powered by a Hispano-Suiza 8Fb engine boosted to give 330abbr=onNaNabbr=on. On 12 December 1920, Sadi-Lecointe flew the NiD-29Vbis to a new world speed record of 313.043abbr=onNaNabbr=on. The aircraft was lost in a landing accident in 1921.

    Nakajima 甲 4 (Ko 4)
  • Japanese licence-built NiD.29, 608 built.

    Operators

    Manchukuo Air Force operated a single ex-Manchurian and ex-Japanese Ko 4 when formed in 1937.[11] [6]
