began to explore space, among which the United States and the Soviet Union were the first. In order to catch up with the gap between the two countries, China launched relevant explorations in the 1960s. In addition, the "Long March 1" carrier rocket was successfully launched, and the "Dongfanghong 1" satellite was successfully lifted off and entered orbit. Today, my country has 4 generations of 19 rocket models, such as Long March 1, Long March 2, Long March 2 E, Long March 3, Long March 4, and so on. According to relevant statistics, my country's Long March series rockets have been successfully launched about 350 times. And it is almost "zero mistakes", so many countries around the world feel bad.
You must know that both the United States and Russia are not as powerful as China in the field of satellite launches. After all, the American "Apollo" spacecraft crash has been unforgettable. So why can China achieve such high achievements? Many unknown scientists and construction teams are inseparable from behind. Gao Fenglin is a household name in my country's Long March rocket project. As a leader in the welding industry in my country, Gao Fenglin participated in the assembly welding project of the Long March II. It is reported that the supporting beam of the rocket shaker needs to be welded at that time, but the difficulty is very high. At this time, Gao Fenglin proposed the method of multi-layer rapid continuous surfacing plus mechanical heat conduction to successfully solve this problem.
In addition, Gao Fenglin was also involved in the assembly projects of Long Three A, B, and C. As these rockets adopted new technologies at that time, they caused a lot of trouble to the welders. Especially the large and small end welding of the engine nozzle, the process of the butt of the ultra-thick material and the ultra-thin material often emits leakage events, and finally Gao Fenglin decided to use the high-strength pulse welding method for welding. And this person has also participated in antimatter detector assembly projects in 16 countries around the world, but due to the difficulty of welding, NASA had to turn to Gao Fenglin for help. At that time, this person could be said to be a technology leader, put forward his own plan, and finally won the affirmation of NASA, and even praised him.
used to offer millions of annual salaries to many foreign companies and wanted to "dig a wall" to let Gao Fenglin work for him, but all were rejected without exception. And Gao Fenglin's reasons were very consistent, "I am very proud to serve the country, but this honor can't be exchanged for much money." However, since entering the Ministry of Aviation Industry in 1982, Gao Fenglin has never thought of leaving this post for many years. He has always contributed his strength in the field of welding and is regarded as a leader in the welding industry in China.
In fact, Gao Fenglin has been in the industry for many years, and often likes to do it himself, even facing some small welding spaces, Gao Fenglin is the first person to rush. After each welding, the clothes are basically drenched with sweat, but there have never been any complaints. It is precisely because of such a group of people that today's China can be so strong, and this is the true "national treasure" of our country.
