The old Shanghai man, who is not tall, is full of wind and frost, and tells his life: he was bitter in his childhood, and he had no money for him to study at home. At the age of 14, he gave the capitalist a work in a factory in Shenyang; in 1952, In a factory in Shenyang, he was engaged in polishing work; in 1954, he was transferred to Dawn Factory for surface treatment and polishing; on May 1, 1956, he was awarded the national model worker, and he was interviewed by Mao Zedong and other central leaders in Beijing; The call of the third line came to Guizhou to participate in the establishment of Xinyi Machinery Factory and worked until 1977.
In the early 1950s, China at that time was poor and white, devastated, without an industrial base, without modern new technologies, and lacking professionals in aviation manufacturing. It is easier to find the first fighter jet on a piece of rubble in the new China that is going to be alive. It is harder than going to heaven. However, it was in this situation that Yang Lan and his colleagues made the impossible possible and sent the plane to success.
Because most of the engine blades at that time were “fat heads and large earsâ€, the machining allowance was large, and the blade profile polishing was a key process in the blade production line with high technical requirements and strong production. When machining can't be done, there is no other way, only grinding it on the grinder by hand polishing, grinding it bit by bit. A 1 kg multi-blank blade, the finished product only needs half of its weight, and 42 qualified blanks are in one batch. From 1 kilogram of blank to 0.5 kilogram of finished product, 42 blanks must be manually thrown away by 21 kilograms. Labor intensity and workload can be imagined.
In the face of difficulties, in the words of Yang Lan, "only a heart is left, and it is necessary to throw it out when it is dead." There is no simple processing method, no advanced technology, no labor-saving processing methods, and no extra time. Yang Lan knows clearly what the mission is, what to do, and how to do it. Faced with the backward working conditions of large dust and incomplete ventilation facilities, Yang Lan is hard to plung into the workshop, strictly controlling the quality of key parts, important parts, quality control of key processes, etc., sitting in front of the polishing machine every day. More than 20 hours, in the process of the process of groping and accumulating experience. For the problems of blade scratching, blade tolerance, blade rework, etc., focus on the combing before the start of the process, find out the uncontrolled and unstable factors in the blade processing, and timely improve and eliminate. Through continuous enhancement of detail management, he finally succeeded in completing the first blade of the first engine of China's first jet fighter. At the scene, the discerning foreign expert carefully identified and raised a thumb at Yang Lanpu, praising him well. The whole section, the whole workshop, and the whole plant boiled. Everyone knows that this will mean that the successful manufacture of the first jet fighter in China is just around the corner. Under the encouragement of this spirit, engineers and first-line production workers are doing research and expanding their results. It takes more than two hours to initially throw a blade, and gradually shortens to 40 minutes, and finally reaches 28 minutes. One piece.
On the morning of July 19, 1956, an aircraft flew for the first time. Marshal Nie Rongzhen rushed to Shenyang to personally cut the ribbon. Along with the roar of the engine, a silver fighter with the red "China 0101" printed on the front of the fuselage vacated, all the people on the scene were extremely excited, and many people left tears of happiness. The flight test was successful, but Yang Lan fell ill. The doctor told everyone that he had a silicosis, and the doctor took out the metal dust from his lungs, which was the result of long-term polishing work. When Yang Lan heard that the plane was going to heaven, his eyes were full of tears. He said that being able to realize this dream is the happiest thing in his life.
The ordinary post is written to be loyal, and Yang Lan’s deeds vividly interpret the spirit of the older generation of aviation people. This spirit is still particularly valuable today, because it is the spirit that is integrated into life and the spirit that is integrated into history and responsibility.
