The Nieuport-Delage NiD 48 was a French single-engine parasol wing light fighter aircraft, designed and built in the 1920s. Its performance was not markedly better than that of the much heavier Nieuport-Delage NiD 62 then going into production, so only two were flown.
The Nieuport NiD 48 was designed for a French 1926 light fighter competition. Unlike many Nieuport designs of the period it was not a sesquiplane but a monoplane, its wing mounted like those of the sesquiplanes over the fuselage in parasol wing configuration. It looked much like a NiD 42 with its ancillary wing removed but had smaller dimensions and only was half the loaded weight. It had a straight-edged, constant chord wing with blunt tips, full span ailerons with a slightly curved trailing edges and a small cutout over the cockpit for better pilot visibility. As on the NiD 42, the wing was braced with Y-form struts from the undercarriage axle support structure, assisted by a cabane of two transverse inverted Vs from the fuselage in front of the cockpit. [1]
Both NiD 48s built used Hispano-Suiza upright V-12 water-cooled engines, with a 298 kW (400 hp) 12Jb in the first prototype and a 373 kW (500 hp) 12Hb in the second, the NiD 48bis. Behind the engine the fuselage had a circular cross-section, with the single-seat open cockpit under the wing trailing edge, tapering to the tail. The cantilever tailplane was mounted at mid-fuselage height and was elliptical in plan with unbalanced elevators. The fin was almost triangular but carried a round edged rudder, also unbalanced, which ended above the fuselage. The NiD 48 had a fixed conventional undercarriage, the mainwheels on a faired axle supported by a pair of rearward leaning V-struts which also carried rectangular radiators for engine cooling. There was a tail skid. [1]
The first airframe was completed in October 1926 and used for static load testing. The first to fly began its official tests in May 1927, with the NiD 48bis following that September. Although lighter than the similarly powered NiD 62, in trials conducted in March 1928 the NiD 48bis bettered it significantly only in rate of climb. but since the NiD 62 was already in production it was decided not to proceed with the NiD 48. [1]
In July 1929 one of the prototypes went to Etampes as a trainer. [1] In the summer of 1930 the NiD 48bis was re-engined with a 179 kW (240 hp), nine cylinder radial Lorraine Algol Junior, as the NiD 481, and used as an aerobatic aircraft, registered F-AJTC; it was withdrawn from use in 1935.

Nieuport, later Nieuport-Delage, was a French aeroplane company that primarily built racing aircraft before World War I and fighter aircraft during World War I and between the wars.
The Nieuport-Delage NiD 52 was a French fighter aircraft of the 1920s. A single-engined sesquiplane, it served with the Spanish Air Force, being operated by both sides of the Spanish Civil War.
The Nieuport-Delage NiD.62 was a French sesquiplane fighter from the early 1930s. This machine was a descendant of a long line of Nieuport-Delage fighters that were designed and built during the years immediately after World War I. The NiD.62 was built in 1931 as a fighter for the Armée de l'Air. It served until the late 1930s, when it was replaced by more modern monoplane fighters. By the time of the outbreak of World War II in September 1939, all of the NiD.62s had been withdrawn from front-line fighter escadrilles but were used as trainers in French flight schools. A few aircraft were employed as target tugs. After the French German Armistice and German occupation of North and West part of France in June 1940, the German Luftwaffe had no interest in the NiD.62s and they were scrapped. None survived the war.
The Nieuport-Delage NiD 42 was a fighter aircraft built in France in the early 1920s, the first in a family of designs that would form the backbone of the French fighter force over the next decade.
The Nieuport-Delage NiD 120 series was a series of French single-seat parasol monoplane fighter aircraft of the 1930s. It was built in a number of versions, fitted with various types of engines, with six aircraft designated NiD 123 being sold to Peru.
The Hispano Suiza E-30, later renamed Hispano E-30, was designed in Spain in 1930 as a multi-purpose intermediate trainer. It was a single engine, parasol wing monoplane. About 25 served with the Spanish armed forces until 1945.
The Nieuport Nie 31 or Nieuport 31 was a single-engine, single-seat monoplane or sesquiplane fighter aircraft designed and built in France in 1919.
The Nieuport-Delage NiD 37 was a single-engine, single-seat monoplane fighter aircraft and racer designed and built in France in the early 1920s. It had a small foreplane to bring the centre of pressure forward. Heavy, slower than expected and with turbo-supercharger problems, development ended without any entering service.
The Nieuport-Delage NiD 43 was a single engine, two seat biplane fighter aircraft designed and built for shipboard use in France in 1924.
The Wibault Wib 1, Wib C1 or, later, Wib 1 C1 was a French World War I single seat, single engine fighter aircraft prototype. Flown near the end of the war, it was not selected for production.
The Wibault 8 or Wib 8 Simoun (Simoon) was a tandem seat, parasol wing fighter aircraft designed and built in France to a 1925 specification which was later withdrawn; only one Wib 8 was completed.
The Wibault 9 or Wib 9 was a single seat, parasol wing fighter aircraft designed and built in France in the 1920s. It was a re-engined version of the relatively successful Wib 7, but failed to reach production.
The Wibault 13C.1 Trombe (Whirlwind), later known as the Wib 130C.1 Trombe was a single seat, parasol wing lightweight fighter aircraft designed and built in France in the 1920s. It was developed into the more powerful Wib 170C.1 Tornade (Tornado) but government interest in lightweight fighters soon waned.
The Letov Š-7 was a single-seat, single-engine biplane fighter aircraft designed and built in Czechoslovakia in the early 1920s. It was designed for a single-seat fighter competition but did not reach production.
The Letov Š-22 was a single-seat, single-engine aircraft designed and built in Czechoslovakia in the mid-1920s. A parasol-wing Dewoitine-style fighter, it was not successful, and only one was built.
The Dewoitine D.15 was a single-engine, single-seat biplane fighter aircraft built in France in the 1920s. Intended to offer structural simplifications when compared with monoplanes, it had a disappointing performance and was soon abandoned.
The Hanriot H.26 was a French single seat fighter aircraft prototype completed in 1923. Only one was built.
The Levy Biche LB.2 was a single seat French sesquiplane fighter aircraft designed to be used from aircraft carriers. With a watertight fuselage, jettisonable wheeled undercarriage and small under-wing floats, it could survive emergency sea touchdowns; it could also be fitted with seaplane type floats.
The Nieuport-Delage NiD 580 R.2 was a contender for a French government contract for a long range, two seat reconnaissance aircraft, issued in 1928. There were eight prototypes in the 1931-2 contest and the NiD 580 was not selected for production.
The SECM-Amiot 130 R.2 was a contender for a French government contract for a long range, two seat reconnaissance aircraft, issued in 1928. There were eight prototypes in the 1931–32 contest and the Amiot 130 was not selected for production.
