Nieuport-Delage Ni-D.29
The Nieuport - Delage Ni -D 29 was a single-seat fighter aircraft. The biplane was used mainly during the 1920s.
History of development
The prototype of the single-seat fighter aircraft (Category C.1) Nieuport - Delage Ni -D 29, a biplane with the same span and ailerons on the upper and lower wing, made his first official test flight on 21 August 1918. The model provided a good performance until the planned summit level, which did not reach it. The second prototype also had a Hispano- Suiza engine and 8Fb the slender trunk with a round cross-section of his predecessor; the range was expanded somewhat. After the prescribed maximum altitude was reached, the Ni -D 29 was the beginning of 1920 in series.
The series machines were improved in detail; the most striking difference was the lack of ailerons on the upper wing and the enlargement of the lower wing. First deliveries to the French Aviation Militaire in 1922 were carried out; the guy went to the Escadrilles SPA 37, 81 and 91 (later 101, 102 and 103 renamed), who were stationed in Germany. The Ni -D 29 were popular, although the pilots complained about the tendency of the machine to spin. Approximately 250 units were built by Nieuport and seven other companies for the French military. 1922-1924, a total of 18 orders.
The Ni -D 29 was soon the most important fighter aircraft of the '20s. Among the French Ni -D 29, which were used against Rif insurgents in Morocco, also a few specimens that had been brought up to standard B.1 and could accommodate small bombs were. The Spanish Nieuport also took part in the fight against the North African insurgents.
Variants

Experimental attack version of the fighter aircraft with six 10 kg bombs; the famous pilot Sadi Lecointe earned with a Ni -D 29 B.1 three honorable mentions and his promotion; only a small number of machines has been converted to this configuration.
Ni -D 29 bis
The Ni -D 29 bis was issued during the Paris Air Show of 1922; they indicated a reduction in wing area and a controllable tail skid, it was built just a prototype.
Ni -D 29G
In parallel with the prototype with Hispano engines built version with Gnome 9N rotary engine; the first of the two copies was later modified for the Hispano motor and provided with two main floats and a rear auxiliary float; the machine then took part in the Seeflugzeugtreffen for the Grand Prix de Monaco 1920; the second specimen was tested as a possible carrier-based fighter aircraft with the Gnome engine, and then rebuilt in 1920 as Ni -D 32RH with a 180 hp ( 134 kW) Le Rhone 9R.
Ni -D 29D

Ni -D 29V
1929 by the designer Mary developed together with the company engineer Gustave Delage lightweight racing aircraft with a wingspan of only 6.00 and a 320 hp ( 239 kW) HS brought 8FB motor; the maximum take-off weight was only 936 kg; the three built racing aircraft were modified several times and have been successful in various events.

Ni -D 29V to
The Ni d to 29V was a rebuilt engine, which should reach by omitting the open cockpit with its windscreen and headrest a higher speed; The pilot sat in the hull and could see the outside only through tiny windows; the destruction of the machine at a landing accident in April 1921 was not a surprise.
