Japanese Jet Fighter Ww2 - Nakajima Kikka (中島 橘花, "Orange Blossom") was Japan's first jet aircraft. It was developed at the end of World War II and the first prototype flew only once before the end of the conflict. It was also known as Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Arms No. 2").
The Imperial Japanese Navy issued a request to Nakajima to develop a vessel to be used as a fast attack bomber. Among the design specifications, the requirements were that it should be able to be built by largely unskilled workers, and that the wings should be foldable. This last feature was to hide the aircraft in caves and tunnels around Japan while the Navy prepared to defend the home islands. Nakajima designers Kazuo Ohno and Kichi Matsumura produced an aircraft that bore a strong but superficial resemblance to the Mon 262.

The Kikka was originally designed to use the Tsu-11, a motor-jet style jet generator that was basically a ducted fan with an afterburner. It was then planned to build the cryfugal flow turbo-jet Ne-10 (TR-10), and the Ne-12, which added a four-stage axial compressor ahead of the Ne-10. Tests of this power plant soon showed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily shelved. It was decided to create a new axial flow turbojet based on the German BMW 003.

Gene's development relationship, based on little more than photographs and a separate drawing of the BMW 003, produced a suitable unit, the Ishikawajima Ne-20, which was finally built in 1945. By mid-1945, the Keka project was Continued redevelopment and at this stage, due to the worsening war situation, the Navy may have considered using the Keka as a kamikaze weapon, although this possibility was doubtful due to the high cost and complexity of manufacturing current turbojet generators. There were other more economical designs designed specifically for kamikaze attacks, such as the simple Nakajima Toka (a Japanese tank designed to absorb damaged genes), the pulse-powered Kawanishi Byaka, and the already famous Yokosuka Ohka. . In ongoing or mass production. .
Compared to the Me 262, the Kaka airframe was shorter and more conventional in design, with straight wings (lacking the short sweep of the Me 262) and tail surfaces.
The characteristic triangular fuselage cross-section was less pronounced, due to the small fuel tanks of German design. The Keka's main landing gear was taken from the A6M Zero and the nose wheel was taken from the tail of the Yokosuka P1Y bomber.
The Kika is often identified as Nakajima J9N1, or sometimes J9Y, which a researcher at the National Air and Space Museum says is incorrect.

The aircraft was officially named 橘花 "Kikka." Like other Japanese aircraft to be used in suicide missions, it received only the name. Imperial Japanese Navy ships were named to resemble US Navy ships of the time frame. The first letter, denoting the character/type of the aircraft, is separated by a number indicating where the aircraft falls within the series of aircraft of the same character, followed by the second letter, indicating the design and manufacture. Indicates the firm, and finally, the second number. Configuring aircraft subtypes. The first three characters remain the same through all substrates for which the aircraft can be designed.
The first prototype began ground testing at the Nakajima factory on June 30, 1945. The following month it was dismantled and flown to Kisarazu Naval Airfield where it was reassembled and prepared for flight testing. The first flight took place on August 7, 1945 (the day after the atomic bomb was dropped on Hiroshima) and was piloted by Lieutenant Commander Susumu Takaka. The aircraft performed well during the 20-minute test flight, the only concern being that the take-off run was slow. For the second test flight, four days later (4 days before the announcement of Japan's surrender), the rocket take-off unit (RATO) was installed in the aircraft. The pilot was unhappy with the angle at which the rocket tubes were set, but because he did not have time to correct them, he decided to reduce the thrust of the rocket from 800 kg to only 400 kg. RATO was initiated four seconds into takeoff, which immediately put the aircraft back on its tail, with the pilot having no effective tail control. After RATO's 9-second burn time had elapsed the nose descended and the nose wheel contacted the runway, causing a sudden deceleration, but both engines were still operating normally. At this point the pilot chose to abort takeoff, but struggled to stop the aircraft and make a ground loop, putting him at risk of moving into second gear. The plane actually went over a puddle of water that caught the landing gear of the tricycle, the plane continued to move forward and did not stop at the water's edge.
At this point, the second prototype was nearing completion, and approximately 23 more airframes were under construction.
One of them was a two-seater trainer. Other proposed follow-on versions included a spy plane, and a fighter armed with two Type 5 30mm guns with 50 rounds per gun.

They are expected to be powered by more advanced developments of the Ne-20, the Ne-20-Kai 5.59 kN (570 kgf) or the Ne-130 8.826 kN (900 kgf) or the Ne-230 8.679 kN (885 kgf) Or called Ne. -330 13.043 kN (1330 kgf), aimed at 15% to 140% better than Ne-20.
After the war, airframes 3, 4, and 5 (and possibly other partial airframes) were brought to the United States for study. Today, two examples survive at the National Air and Space Museum: the first is a kayak that was taken to Patuxet River Naval Air Base, Maryland for analysis. This aircraft is very incomplete and is believed to have been assembled from a range of semi-finished airframes. It appears in the black and white photo in bare metal with two Ne-20 engines mounted under the wings. It remains in storage at the Paul A. Garber Conservation, Restoration and Storage Facility in Silver Hill, Maryland. Cter Udvar-Hazy NASM has another kayak on display in the Mary Baker Restoration Hangar. One theory from a 2001 correspondence with Japanese propulsion expert Kazuhiko Ishizawa is that Nakajima built the museum's Kaika airframe for load testing, not flight testing. This may explain why the nacelles on the museum's Kaka airframe are too small to hold the Ne-20 nacelles.
Two Ne-20 jet engines were brought to the Chrysler Corporation for analysis in the United States in 1946. W. I. Chapman, who was in charge of the project at the time, only revealed this in 2005. A working engine was assembled with parts. Of the two Ne-20s, and was tested for 11 hours and 46 minutes. A report was issued on April 7, 1947, entitled "Japanese NE-20 Turbojet Generator." Construction and Performance”. The document is now on display at the Tokyo National Museum of Art.
A modified version of the design was also launched from a 200 meter long catapult, the "Nakajima Kaika-kai Prototype Turbojet Special Attacker". It has a weight of 4,080 kg and a maximum speed of 687 km/h at a distance of 6,000 m.

Published translations do not agree, and most are simplified, especially for plants, where the Japanese refer to a specific variety and the translations are general except for a broad variety. The Mitsubishi A6M "Zero" is a long-range fighter aircraft carrier, based on the earlier design. Built by the Mitsubishi Aircraft Company, part of Mitsubishi Heavy Industries, and operated by the Imperial Japanese Navy from 1940 to 1945. The A6M is known as the Mitsubishi Navy Type 0 Carrier Fighter (零式艦戦, 零式艦戦, 旦式艦戦旦-旦式艦戦旦式艦戦, ) or Mitsubishi A6M Rei-s. A6M pilots commonly refer to it as Reis (零戦, zero fighter), the last digit being "0" for Imperial Year 2600 (1940) when it entered service with the Imperial Navy. The official Allied reporting name was "Zac", although the name "Zero" (from Type 0) was also used.
The Zero was considered the most capable carrier-based fighter in the world when it was introduced at the beginning of World War II, with excellent maneuverability and a very long range.

But by mid-1942 a combination of new tactics and the introduction of better-equipped pilots brought the Zero to parity.
By 1943, the Zero was less effective against new Allied fighters due to design limitations. It lacked hydraulic reinforcement for its ailerons and rudder, which made maneuvering at high speeds extremely difficult. By 1944, Allied fighters were approaching the A6M's level of capability and durability.
