Shenyang JJ-1

Descripción del producto

The 红专***3 Hong Zhuan "Red Special" or 歼教*1  Jian Jiao "Fighter Trainer" also know as the Shenyang JJ*1

红专***3 歼教*1 (战斗机 教练员 航空器*1)

The second kit of the International Resin Modellers Associationis Chinas first completely indigenous jet aircraft, the Shenyang JJ*1. Originally this jet was known as the 红专**3 Hong Zhuan "Red Special" because it was the premier jet plane perceived, designed and built in the Peoples Republic of China. Later the name was changed to 歼教*1 Jian Jiao "Fighter Trainer" or 沈阳 歼教*1 Shenyang JJ*1 because this aircraft was created by the Shenyang Aero Institute 沈阳飞机制造厂 (JJ*1 was the abbreviation for 战斗机 教练员 航空器*1 or fighter trainer aircraft*1). We have been lucky enough to have one of the actual designers, Dr. Bushi Cheng to help us!

When a divergent perspective on communism/socialism evolved between the Chinese and Soviets in the early****0s, the response of the Soviet Union was to break off relations with the Peoples Republic of China. This involved withdrawing all technical advisors, including aviation personnel, stopping all shipments of aircraft to China, including spare parts, and taking back or destroying any technical drawings, manufacturing procedures or jet plans for Chinese aviation.

This left China with only outdated aircraft with which to train its jet fighter pilots. The Peoples Liberation Army Air Force (PLAAF), also known as the People's Republic of China Air Force (PROCAF), felt that after student pilots had mastered propeller aircraft, they still needed a transition to jet aircraft but, not directly to full jet fighters. Thus the PLAAF approached the engineers of the Shenyang Aero Institute, including Professor Bushi Cheng, for a jet trainer.

The Shenyang Aircraft Development Office discussed the need with the Air Force to make sure the concept was clear. Next they sat down and began to design the jet based on what they knew and on the resources available. Upon acceptance by the committee, the technical drawings went to the manufacturing deparment to build the first prototype. The result was a very efficient and completely Chinese jet.

The JJ*1 was a straight-wing, un-swept tail-plane, aircraft built to be very friendly to the student pilot. It was also one of the first trainer jets designed specifically for its purpose and not an adaptation of an existing fighter design. The student sat in the front with the instructor in the back seat. One unusual feature was that the students canopy opened with a side hinge while the instructors canopy slid back.

The engine was a SADO (Shenyang Aircraft Development Office) PF*1A, a Chinese version of the Soviet Klimov RD***0, which was itself a copy of the British Rolls-Royce Derwent V centrifuge turbojet. Armament consisted of a single *3 mm canon. Another aspect for the JJ*1, discovered upon completion, was its capability as a close-support, ground-attack platform. It could fly slow enough to support troops in a close combat situation, yet speed away when necessary.

Three Shenyang JJ*1s were constructed with one being a static test airframe. For trials the finish was overall natural aluminum with only national markings. Later one of the aircraft would receive a numeral and become known as "**1 red" during the demonstration flights.

In one painting/illustration, a JJ*1 is depicted with tail stripes of red-white-red-white as used during the Chinese Revolution (known also as the Chinese Civil War) to commemorate the conflict, which soldiered on through the ***0s. These would be twelve in number based on the traditional Chinese day of *2 hours before the introduction of Western time. Initially this format was used by the Republic of China on almost all aircraft in blue-white-blue-white. The stripes were later used by the Chinese Communists, then the Peoples Republic of China in the red-white format, to differentiate Communist from Nationalist aircraft. There were also variations on the Communist side of 7 and 9 stripes with one Jian*2/MiG**5 even sporting *5 on its rudder.

One major influence on the JJ*1 was foreign aircraft. The PLAAF had taken note of the structure of top-performance jets from other nations. For this reason the air intakes were built on the sides of the JJ*1 in similar fashion to the Grumman F9F Panther of the U.S.A., the Hawker F.1 Sea Hawk of the U.K., the Sud Ouest SO****0 Espadon of France, Fiat G.*0 of Italy, Saab J**1R of Sweden and Avro CF***0 Canuck of Canada. This allowed for a radar placement in the nose of the aircraft.

Although the nose radar was an advantage over the Jian J*2/MiG**5 and Jian J*5/MiG**7 from the Soviet Union, the Soviets too had made this discovery in the late ***0s with the Lavochkin La***0 series of jets. Also Germany and Japan had planned to introduce side-intakes on designs such as the Messerschmitt P.***0 and Yokosuka R2Y*-II Keiun, respectively, had the war continued.

The first flight was performed on *6 July ***6 (or ***8?) by Comrade Yu Zhenwu of the PLAAF who put the aircraft through its paces. The JJ*1 performed quite well, especially in the role it was designed for.

In the end the JJ*1 was never put into production because the PLAAF concluded that it would be possible for pilots to make an immediate transition from propeller airplanes to jet aircraft. Also, propeller aircraft were concluded to provide sufficient ground-support. Thus Chinas second aircraft endeavor came to a quiet ending.

Never-the-less, the Hong Zhuan***3 or Shenyang JJ*1, gave China its first opportunity to prove to itself and others that a purely domestic Chinese jet aircraft was not only possible, but would become typical as the Chinese aviation industry gained experience and grew into one of the most prominent in the world.
