in January, 1956, the Central Committee of the CCP convention intellectual problem meeting, Secretariat of the Central Committee of the Communist Party of China Secretary Zhou Enlai has done "about Intellectual Problem Report", originating “marches to the science” the summons to the party and the whole nation. Afterward the nation has started “marches to the science” the upsurge. After national science program meeting, our country aircraft industry resolved that goes out mimics the Soviet aircraft's aspect simplex according to the Soviet blueprint, develops our country own Aircraft Design strength.
The aviation industry bureau resolved that establishes the first aircraft design office, the initial period by the Shenyang Aircraft plant substitute management, and adjusts four people from the air bureau: Aircraft technology Section Chief Xu Shun Shou, senior engineer then yellow will thousand, after as well as founding of the nation, from the university aviation is graduation Gu Songfen and the regulation often. The people facing the prosperous development the enterprise, had filled the undertaking great ambition at that time.
The new design's aircraft cannot be “follows a model” to the overseas aircraft the imitation, also makes some “the minor repair slightly modifies” the piece of work, but embarks from aircraft's mission demand, chooses the appropriate method from the world technical aeronautics main storehouse, crosses “the project to be comprehensive” forms own design. This is new China from designs the design path which the first aircraft starts to establish, is also the main design path which the world aviation development follows.
The first aircraft design office design's first aircraft to annihilate teaches 1, as soon as aircraft's population design drawing just completed, instantly enters the actual project approach. This time the factory just mimicked the successful Soviet Union's Mig - 17 jet fighter planes, comes the designers from the factory to be right “the Mig type aircraft” to be familiar. But, the first aircraft design office does not prepare which to let China independently design the aircraft becomes “the Mig computer” the replica. Xu Shun Shou proposed especially for this reason: “must be familiar with Tang poem 300”, namely should be familiar with each kind of different aircraft, then carries on the choices, does not want “only the Mig theory” absolutely, do not design one kind “the Mig computer” anomalous form.
Afterward annihilated teaches 1 to select the US English side mounted air ducts method, but was not the Soviet tradition nose air admission arrangement. Because in the long run, the nose section is suitable in installs antenna's best spot, but the radar in regard to the modern operational aircraft is extremely important. Even though the trainer aircraft does not need to install the complex radar, but controls this kind of side mounted air ducts the design technique to have the use very much in regard to the development high performance service airplane.
at the beginning of 1958, independently designed the manufacture after China to annihilate teaches 1 deployed, have not waited to fly the nose to fly, the first aircraft design office under the Soviet Yakovlev Designing bureau expert Mar article's help, the fermentation independently designed aircraft's next target, made great strides forward to the supersonic jet fighter plane.
in April, 1958, the aircraft design office proposed that the design east wind 104 fighter plane's tentative plans, aircraft's design value is for the maximum level speed Mach number 1.4, the ceiling 17000 meters, the climb rate is bigger than for 70 meters/seconds, the range 1000 kilometers, a cruise duration 1 hour 20 minute, aircraft's power unit uses a Soviet-made рд-9 б turbojet engine, has all-weather operational capability.
But in just the past in March, 1958, Air Force commander Liu Yalou required to design one kind to be able the attack plane which attacks to the place, this computer is called east wind 106, the schematic diagram often waits by the regulation the human to complete in Shenyang. Because later 112 factories must research the east wind 102, east wind 107, east winds 113, afterward must mimic Mig - 19S, therefore the east wind 106 transferred 320 factory research and developments, simultaneously in the Shenyang first aircraft design office qualifications old Engineer Lu Xiaopeng will adjust Nanchang to work.
in May and June, 1958 between, the design team started to inquire into improves the east wind 104 design speeds. on August 6~15, 1958, the aircraft industry technical meeting convened in Shenyang. This is after annihilating teaches 1 test flight success, plans an ideological mobilization and the population which independently designs to the Gauguin broad technical aeronautics field development disposed, simultaneously at the meeting proposed surpasses the world advanced level the design program, resolved that improves the east wind 104 design indices to the Mach number 1.8, the ceiling 20000 meters, the new model is called east wind 107.
The east wind 107 plans use 2 new research and developments the Red Flag 2 jet engines, in the entire distribution refer to American Chance Wort company's F-8 “the crusader” the ship-borne fighter, including F-8 to adapt the shipboard rise variable incidence wing.
] 958 year in August, the east wind 107 predesigns complete basically. The min first miny Mach build understood ha the war industry east wind 113 indices achieve “the pair 25” after situation, then leads aircraft industry Bureau Chief Wang Xiping, assistant commissioner the oil river, Xu Lu Yu, Li Zhaoxiang, Shenyang Aircraft plant Manager Niu Yinguan, Chief Engineer Gao Fangqi, aircraft design office Xu Shun Shou, the yellow will thousand, leaves honorable and so on to go to the Harbin Military engineering Institute to hold on-the-spot meeting. Carries on the visit to study. At on-the-spot meeting, ha the war industry did on the east wind 113 design proposals introduced in detail that comrades attending the forum has carried on the discussion. Finally, the min first miny Mach build said in the speech: The institute dares the spirit which wants to dare to do is good, but the realism has been short a point, a romanticism many point. And said that we must set up the opposite. Afterward in east wind 113 fighter planes “pair 25” under the high index influence, the east wind 107 maximum velocities improve to the Mach number 2.
When convention east wind 113 fighter plane plan examining committee, management's representative proposed that with its dispersion energy, was inferior the east wind 113 and the east wind 107 merges, researches one kind of l.8 a Mach fighter plane. This has evoked the intense discussion at the meeting, finally makes two project both on the conclusion. After the meeting, Chen Geng opposes this matter, thought that “two both do, also does inadequately. Can do one advanced only, cannot do backwardness”. This opinion is accepted by Peng Dehuai, therefore has cancelled the original meeting conclusion. Therefore in October, 1958 reported in the central report to mention the east wind only 113. However, the east wind 107 plans already started and have made certain progress, if 113 suspended as a result of the east wind, rather was a pity. Although therefore holds the examining committee once more which manages by air force Commander Liu Yalou, at the meeting has the argument, but the conclusion is agreed east wind 107 continues the trial production, and authorizes by the national aviation trial production group's name.
This resolution caused at that time the east wind 107 design teams to dance with joy, as a result of its preparatory work development early, as soon as therefore by the higher command to authorize, the experimental work comprehensively unfolded, the very quick blueprint comprehensively originating and starts the experimental work.
in December, 1958, the Shenyang aircraft design office completed the east wind 107 working drawing designs basically. Afterward acts according to the protocol which, Soviet decided that on February 27, 1959, led by aviation industry bureau Assistant Commissioner Xu Changyu, the leaf honorable and so on designers brought the east wind 107 blueprint informations to go to Soviet to consult. At the same time, also escorts to the east wind 107 models Soviet Union to catch a chill. The original east wind 107 takes one kind of our country the new fighter plane which researches, not only the measures of performance are high, and has used many new technologies, therefore should strictly encryption to the Soviet, avoids Soviet Union knowing our country's this new model. However 107 compares the east wind 113 indices with the east wind to be higher, therefore the east wind 107 pieces can attain Soviet Union to catch a chill. The east wind 107 technical advisory works carry on about 8 times, to in September finished in the same year. In the consultation detected that the design proposal has the significant technical question, is mainly the velocity cannot achieve, the drag estimated has been small, this was because the angle of attack variable wing intensity reduced causes, the aircraft performance could not meet the predetermined requirements. Moreover more importantly Soviet Union continually side mounted air ducts this already in annihilated teaches on 1 to succeed the utilization air admission topological design also to deny, Soviet Union is called the length is smaller than 20 meters aircrafts is not suitable for with the side mounted air ducts. The basically east wind 107 to changes from the side mounted air ducts the angle of attack wing by the Soviet total repudiation. However corresponds with it was enlarges the design in PД-9Б the engine foundation the Red Flag 2 engines to obtain Soviet's affirmation.
This situation after in June report aviation industry bureau, in August, authorizes by min first miny Mach build minister, the aviation industry bureau resolves the stop trial production east wind 107, but the design modification work still continued to carry on. Engine's experimental work also continues to carry on.
after in January, 1959 sent the east wind 107 trial production blueprints, in February ~ in May, the aircraft design office modified to the blueprint examination, in the same year in May, originating after has modified blueprint east wind 107 A, new east wind 107A has cancelled changes the angle of attack wing design, changed the stationary triangle high wing, but preserved side mounted air ducts this design. After the modification aircraft needs to carry on the blowing, however at that time our country only then the HK-2 transonic wind tunnel which imported from Democratic Germany. However to catch up with in October 1, 1959 offers a gift, the aircraft hurried caught a chill. Because afterward the expectation use's Red Flag 2 engines complete with difficulty according to the plan, the aircraft design office also modification designs east wind 107S (power to change to the Soviet PД-9Б engine). In September, has designed in the same year the east wind 107Z tactic reconnaissance aircraft according to the factory party committee's resolution, simultaneously as 107A testing machine. Later has designed transition plans and so on east wind 107J ground attack trainer aircraft, has not put into the trial production.
But takes uses the side mounted air ducts topology similarly the east wind 106, after changing to 320 factories, renamed eagle 302, Lu Xiaopeng has made the improvement to the initial design, like used the area law the aircraft body, lengthened computer the nose cone, after using, operated the type cockpit cover and so on, caused this computer development famous 5 attack planes.
As for has the future to spread the wings very much originally the blue sky east wind 107, has made the full size wooden model, after merely then stopped the development. However the essential road must walk, in east wind 107 triturating, although the road is rough, but gained in the substantial experiences. Afterward our country's designers are having a thorough understanding in thoroughly the Mig - 21 aircraft foundations, the success researched advanced has annihilated the 8II upper air superfighter.
It looks you guys has known all of Chinese secret project... ;D
