Profile study of the CW-21. The CW-21B was a development of the original aircraft incorporating the flush fitting, inward retracting landing gear used on the CW-23, and other refinements. Curtiss sold twenty-four CW-21Bs to the Netherlands East Indies (N.E.I.) Air Force and also made sales of the CW-22 to the N.E.I. and other customers. II.

The CW-21 was a fighter interceptor based on the CW-19. Intended to be a high altitude fighter with good climb rate and good armament, it caught the interest of the Chinese government. China received 3 fully built CW-21s and 27 kits to be armed.

Designated CW-21, the fighter had a Wright R-1820-G5 Cyclone nine-cylinder radial engine rated at 1,000hp for take-off and 850hp at 1830m, and an allmetal stressed-skin structure with a semi-monocoque fuselage.

The CW-21 Demon was an attempt to develop a lightweight Interceptor from the CW-19R general purpose aircraft. The project started in 1938 with the first prototype flying in January of 1939 and carrying the civil registration NX19431.

Budget-conscious China showed early interest in the CW-21 and delivered a prototype for testing. The Chinese liked what they saw and pushed for a procurement contract with Curtis-Wright. During this period, the prototype was actually used against the Japanese army, with good results reported when the aircraft successfully shot down enemy bombers.

ww2dbase Curtiss-Wright Model 21 light fighters were originally developed by George A. Page and Willis Wells of Saint Louis Airplane Division of Curtiss-Wright in 1938, who intended on developing a small and nimble fighter whose sole purpose was to quickly climb to altitude to harrass enemy bombers, sacrificing dogfight capabilities (ie. the ...

The wing outer panels housed a further fuel tank of 14 gallons each – resulting in a total fuel capacity of 96 gallons. All-metal flaps were placed in the wing centre section and ...

The CW-21 was designed during the late 1930s. It combined light weight construction with a powerful engine, which resulted in an excellent rate of climb and manoeuvrability, allowing the fighter to quickly reach the height of attacking enemy aircraft, and attack them.
