Nakajima Kotobuki
The Nakajima Ha1 Kotobuki (寿, "Longevity") was an aero-engine developed by Nakajima. It was a radial piston developed under licence from the Bristol Jupiter. Design and development In 1917, Chikuhei Nakajima set up the "Airplane Institute" at Ojima Town in Gunma Prefecture. In 1918 they built their first airplane; the "Nakajima Type 1" with a U.S.A. made engine.Engine development at Nakajima 1923 - 1945 In 1920 the company sent Kimihei Nakajima to France to study European advances, and in 1922 started their own engine factory in Tokyo. This led to production of engines based on the Lawrance A-3 two-cylinder air-cooled horizontally opposed engine. At the time the Lawrence was an oddity. Most air-cooled engines at that time were rotary engines using cylinders that rotated together with the propeller, but Kimihei overheard that an engine with good cooling capability with fixed cylinders was being developed in England. He observed the English Gloster Gamecock fighter with its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nakajima E4N
The Nakajima E4N was a Japanese shipboard reconnaissance aircraft of the 1930s. It was a two-seat, single-engine, equal-span biplane seaplane used primarily by the Imperial Japanese Navy. Development The first prototype of the Type 90-2 Reconnaissance Seaplane, or E4N1, flew in 1930. This was fitted with twin floats and had no cowling for the engine. This prototype was rejected. The type was completely redesigned as the Type 90-2-2 or E4N2, with a single main-float and twin, wing-mounted outriggers and introduced a cowled engine. This entered production for the Navy in 1931. A landplane version of the Type 90-2-2 was developed as the E4N2-C with a tailwheel undercarriage Operational history The E4N2 was employed as a shipboard reconnaissance seaplane launched by catapult. In 1933, nine E4N2-C airframes were converted to P1 mail planes. Single-seat landplanes with an enclosed cockpit, these were employed on night-mail services between the Japanese Home Islands.

Nakajima Ki-27
The was the main fighter aircraft used by the Imperial Japanese Army Air Service up until 1940. Its Allied nickname was "Nate", although it was called "Abdul" in the "China Burma India" (CBI) theater by many post war sources; Allied Intelligence had reserved that name for the nonexistent Mitsubishi Navy Type 97 fighter, expected to be the successor to the carrier-borne Type 96 (Mitsubishi A5M) with retractable landing gear and an enclosed cockpit. Design and development In 1935, the Imperial Japanese Army held a competition between Nakajima, Mitsubishi, and Kawasaki to design a low-wing monoplane to replace the Kawasaki Ki-10 (Army Type 95 Fighter) biplane. The new fighter was to have also a better performance than the experimental Mitsubishi Ki-18. The results were the Nakajima Ki-27, the Kawasaki Ki-28, and the Mitsubishi Ki-33 (a modification of the Mitsubishi A5M carrier-based fighter). The Nakajima design was based on its earlier Ki-11 monoplane fighter which lost to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nakajima Ki-8
The was an unsuccessful attempt by the Nakajima Aircraft Company to interest the Imperial Japanese Army Air Force in a two-seat modern monoplane fighter. Design & Development Development of the Ki-8, (a.k.a. Nakajima DF), began in 1933, based on an all-metal two-seat aircraft, featuring low inverted gull wings, with fixed and spatted landing gear, powered by a single Nakajima Kotobuki Ha-1-3 radial engine. Proposed armament consisted of twin 7.7 mm (.303 in) machine guns firing from between the engine cylinders and a third 7.7 mm (.303 in) machine gun on a flexible mount on the back of the rear cockpit. In initial testing, the aircraft proved unpopular with test pilots, who raised concerns about the design's aerodynamic stability . The initial prototypes were also plagued with a variety of manufacturing defects and malfunctions. Though corrections were made to improve initial design and stability problems, the performance of the aircraft was considered ...

Nakajima A1N
The Nakajima A1N, or Navy Type 3 Carrier Fighter, was a Japanese carrier-based fighter of the late-1920s and early-1930s. It was a licensed copy of the British Gloster Gambet fighter, built by the Nakajima Aircraft Company for the Imperial Japanese Navy. Approximately 150 were built in two versions, the A1N1 and A1N2. Development By 1926, the Imperial Japanese Navy's Mitsubishi 1MF fighters (also known as Type 10 Carrier Fighters) were in need of replacement and so it asked three of the leading Japanese aircraft manufacturers, Nakajima, Mitsubishi and Aichi for proposals for a new carrier-based fighter. Nakajima purchased a licence from the British Gloster Aircraft Company for production of the Gloster Gambet. It was a private venture design for a carrier-based derivative of their earlier Gloster Gamecock fighter. The prototype Gambet was built by Gloster and first flew on 12 December 1927. The prototype Gambet was shipped to Japan early in 1928. After modifications were made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi Ki-18
The was an unsuccessful and unsolicited attempt by Mitsubishi to meet a 1934 requirement issued by the Japanese Army for a modern single-seat monoplane fighter suitable to the needs of the Imperial Japanese Army Air Force. During this competition, Nakajima entered the Nakajima Ki-11 (which was somewhat similar to the Boeing P-26 Peashooter), and Kawasaki entered the more maneuverable Kawasaki Ki-10 biplane. The competition was won by Kawasaki, but the new fighter was not accepted by the IJAAF with much enthusiasm. Design and development In 1934, Mitsubishi had developed the Ka-14 9-Shi fighter prototype specifically for an Imperial Japanese Navy requirement. The design exhibited outstanding performance, and with the Navy's consent, the Army placed a contract with Mitsubishi for a modified version for evaluation, which was designated the Ki-18. The Ki-18 was a low-wing monoplane of all-metal construction with fabric-covered control surfaces. It was powered by a Nakajima Koto ...

Nakajima Ha-5
The Nakajima Ha5 is a twin row, 14 cylinder air-cooled radial aircraft engine built by the Japanese Nakajima Aircraft Company. The engine was a development of earlier single-row Japanese engines, the Kotobuki and Hikari, which had combined features of the Bristol Jupiter and Pratt & Whitney R-1340 Wasp designs. First introduced in a 1,000 PS prototype in 1933, about 7,000 civilian and 5,500 military Ha-5's were built during World War II. The Ha-5 had separate cam-discs for the front and rear rows of cylinders like American designs, rather than using a single, front-mounted cam-disc with long and short pushrods to operate both rows of cylinder valves. The Ha-5 was a twin-row development of the Nakajima Hikari, which was itself a development of the Nakajima Kotobuki. It spawned several improved variants, namely the Ha-41, with a single stage supercharger, and the Ha-109, which featured a two-speed, single stage supercharger. The later Ha-219 was based on the same cylinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yokosuka B4Y
The Yokosuka B4Y, (Navy Type 96 Carrier Attack Bomber), carrier-borne torpedo bomber was used by the Imperial Japanese Navy Air Service from 1936 to 1943. The B4Y replaced the Mitsubishi B2M2 and was the last biplane bomber used operationally by the Imperial Japanese Navy. The Allied reporting name was "Jean". Design and development In 1932, the Imperial Japanese Navy issued a requirement for a new carrier-borne attack aircraft. Aichi, Mitsubishi and Nakajima responded to this requirement and each built a prototype. None of these aircraft were deemed satisfactory, and the service thus issued in 1934 a new requirement, 9-''Shi'', for a more capable aircraft to replace the obsolescent Yokosuka B3Y. The B4Y was designed by Sanae Kawasaki at the First Naval Air Technical Arsenal at Yokosuka. Regarded only as an interim type, the Navy wanted a torpedo bomber offering performance comparable to the Mitsubishi A5M monoplane fighter. The result was a biplane with fixed landing ge ...

Nakajima C3N
The Nakajima C3N-1 (also designated Type 97 Carrier Reconnaissance Aircraft) was a prototype Japanese carrier-based reconnaissance aircraft of the 1930s. A single-engine monoplane with a fixed undercarriage, although only two examples were built, they were both used operationally, carrying out land-based reconnaissance missions during the Second Sino-Japanese War. Development In 1935, the Nakajima Aircraft Company submitted a design to meet an Imperial Japanese Navy Air Service requirement for a carrier based-reconnaissance aircraft. The design, designated Type S by Nakajima, had a great deal in common with the Nakajima B5N torpedo-bomber that was being developed in parallel. The Type S was a low-winged single-engined monoplane of all metal construction, with upward folding wings for ease of stowage aboard carriers. Unlike the B5N its undercarriage was of fixed tailwheel type with spatted main wheels. Power was by the same Nakajima Hikari radial engine used by early B5Ns. A ...
