Japanese Fighter Jets Ww2 - Nakajima Kikka (中島 橘花, "Orange Blossom") was Japan's first airplane. It was developed at the end of World War II and the first prototype only flew once before the conflict. It is also called Kōkoku Nigō Heiki (皇国二号兵器, "Emperor's Weapon Number 2").
The Imperial Japanese Navy commissioned Nakajima to develop a similar aircraft for use as a fast attack bomber. Design specifications include being able to be built mainly by unskilled labor and the wings must be foldable. This last feature allowed the aircraft to hide in Japanese caves and tunnels while the navy began to prepare for the defense of the home islands. Designers Kazuo Ohno and Kichi Matsumura Nakajima created an aircraft that resembled the Me 262 but was shallower.

The Kikka was designed in preliminary form to use the Tsu-11, a common turbojet-style jet engine that is essentially a tube fan. Subsequent designs were planned around the Ne-10 (TR-10) and Ne-12 triple-flow turbojets, which added a four-stage axial compressor to the front of the Ne-10. Tests of this power plant soon showed that it would not produce the power needed to propel the aircraft, and the project was temporarily halted. The result was the decision to produce a new axial turbojet, based on the German BMW 003.
Zero Or Hero? The Main Fighter Of The Japanese Fleet
The development of the engine was problematic, and based on photos and single drawings of BMW 003, a suitable unit, the Ishikawajima Ne-20, was finally built in 1945. By mid-1945, the Kikka project was in place. once again making progress and at this stage, due to the worsening war situation, the Army may consider using the Kikka as a kamikaze weapon, although this prospect is questioned due to the high cost and complexity associated with the manufacture of contemporary turbojet engines. . Other, more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb the aging stock of Japanese engines), the Kawanishi Baika with pulse jets and the more popular Yokosuka Ohka, are underway or already in mass production. . .
Compared to the Me 262, the Kikka airship was smaller and of a more conventional design, with a straight wing (lacking the light sweepback of the Me 262) and a tapered tail.
The characteristic triangular fuselage of the German design is less prominent due to the smaller fuel tank. The Kikka's main landing gear was taken from the A6M Zero and the nose wheel from the tail of the Yokosuka P1Y bomber.
Kikka is often identified as Nakajima J9N1 or occasionally J9Y, which is incorrect according to researchers at the National Air and Space Museum.

The official name of the aircraft is 橘花 "Kikka". Like other Japanese aircraft intended for suicide missions, it received only one name. Imperial Japanese Navy aircraft were named after US naval aircraft at the time. The first letter indicates the role / type of aircraft, separated by a number indicating where the aircraft resides in the series of aircraft with the same role, followed by the second letter indicating the design and manufacturing company, and finally the second number. doting plane subtype. The first three characters remain constant for all sub-variants in which the aircraft can be built.
The first prototype made ground tests at the Nakajima factory on June 30, 1945. The following month it was disassembled and shipped 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 Hiroshima atomic bomb), under the command of Lieutenant Commander Susumu Takaoka. The aircraft performed well during the 20-minute flight test, with the only concern being the length of the takeoff. For the second test flight, four days later (4 days before the Japanese surrender), a rocket assisted take-off unit (RATO) was installed on the aircraft. The pilot was concerned about the angle at which the rocket tube was set, but without time to correct it he decided to reduce the rocket's thrust from 800 kg to only 400 kg. The RATO activated four seconds after takeoff, immediately clipping the aircraft to the tail, leaving the pilot without effective tail control. After the RATO burn time of nine seconds, the nose dropped and the nose wheel made contact with the runway, causing a sudden deceleration, but both engines were operating normally. At this point the pilot decided to cancel the takeoff, but the struggle to brake the plane and make a ground loop only risked it running to another facility. Finally, the plane passed through the drainage ditch holding the landing rickshaw, the plane continued to slide forward and came to rest just near the water's edge.
At this time, the second prototype was almost finished, and about 23 aircraft were under construction.
One of them is a two-seater coach. Other proposed versions include reconnaissance aircraft and fighter aircraft armed with two Type 5 30 mm cannons with 50 rounds per cannon.

This is expected to be supported by further development of the Ne-20, known as Ne-20-Kai 5.59 kN (570 kgf) or Ne-130 8,826 kN (900 kgf) or Ne-230 8,679 kN (885 kgf). The Ne-330 13,043 kN (1330 kgf), is projected to have 15% to 140% better thrust than the Ne-20.
After the war, planes 3, 4 and 5 (and possibly other partial planes) were brought to the US for analysis. Today, two examples survive at the National Air and Space Museum: The first is Kikka, which was flown to Patuxt River Naval Air Station in Maryland for study. This plane is not very complete and is believed to be a patchwork of various semi-completed planes. Shown in black and white photo in bare metal with two Ne-20 engines mounted under the wing. It is still in storage at the Paul E. Garber Conservation, Restoration and Storage facility in Silver Hill, Maryland. The second Kikka is on display at the NASM Udvar-Hazy Cter in the Mary Baker g Restoration Hangar. Correspondence with Japanese propulsion specialist Kazuhiko Ishizawa in 2001 suggested that Nakajima built the Kikka Museum aircraft for payload testing, not flight testing. This may explain why the engine nacelles of the Kikka Museum aircraft are too small to cover the Ne-20 engine.
Two Ne-20 jet engines were brought to the US and in 1946 to the Chrysler Corporation for study. This was only revealed in 2005 by W. I. Chapman, who was in charge of the project at the time. Engines working on parts of two Ne-20s were assembled and tested in 11 hours and 46 minutes. A report was published on April 7, 1947 entitled "Japanese NE-20 Turbo Jet Engine. Construction and Performance." The document is currently on display at the National Science Museum in Tokyo.
There is also a modified version of the design to be launched from a 200m catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker". It has a total weight of 4,080 kg and a maximum speed of 687 km/h at 6,000 m.

Kikka's second prototype of the Ne-20 engine is on display at the Stev F. Udvar-Hazy Cter in Chantilly, Virginia.

Published translations are inconsistent and simplified, especially for plants where the Japanese refer to a specific variety and the general translation only refers to a broader type. The Japanese military has world-class fighter planes. How wrong they are. Aircraft - known as "Zeke" or "Zero" - dominated the skies in the early stages of World War II. The single, low-wing monoplane proved to be the most capable aircraft-based fighter in service at the time, giving the Japanese navy almost guaranteed air superiority.
The A6M, designed by Jiro Horikoshi, is also noted for being the first carrier-based fighter capable of attacking ground-based opponents. However, from 1943, the tide turned against the Zero with the introduction of more powerful Allied fighters.

The A6M was manufactured by Mitsubishi Heavy Industries and was powered by a Nakajima Sakae 1,020 horsepower 14-cylinder (seven in-line staggered) air-cooled radial engine. It is hardly a powerful machine, but the designers did everything they could to reduce the weight.
However, the effort to make it fast and light means that it has very little armor and is vulnerable to even the lightest enemy weapons. This was not a problem when the speed and agility of the aircraft allowed it to dominate the skies, but when the superior air power of the Allies left.
