On the evening of December 27, the Long March 5 Yaosan rocket flew into the sky with a thundering roar. Two years later, the Chang 5 rocket took off again, focusing the world's attention.
During the long journey of Long March 5 from Tianjin to Wenchang, the rocket needed to be transported all the way to Qinglan Port and then transferred to the launch site. Behind the transfer of Fat 5, thanks to a group of "courier guys" like Yu Jinwei ".
Come "fully loaded" and return "empty"
To transport a big rocket, you have to rely on a "big truck". There are a number of specially equipped vehicles at the Wenchang launch site in Hainan. They have different shapes and different uses, but they are responsible for important tasks such as receiving rockets, towing satellites, and transporting low-temperature fuel. Behind the
behemoth, there is a dark face. Henan driver Yu Jinwei and his colleagues drove the rocket from Qinglan Port to the launch site in a specially equipped vehicle. The rocket transport vehicle that transports the Long March 5 rocket is nearly 50 meters long, more than 6 meters wide and nearly 8 meters high.
When the Long March 5 rocket was placed on the specially loaded truck with a hook and the rearview mirror was blocked by the container, Yu Jinwei's inner battle began. Without being able to see the rear of the vehicle and having to cooperate with the observer through commands, it is a protracted battle of endurance and driving skills to successfully pass the launch site road and successfully reverse the vehicle to remove the rocket body in one go.
Only when Yu Jinwei went to the launch site with a "full load" and returned to the depot with an "empty load" was he able to win the battle in his heart.
html After 2019’s aerospace career and 19 years of driving experience, Yu Jinwei has become the master of driving a “huge vehicle” and smoothly returning the rocket body to the launch site when there is less than 0.4 meters left on both sides of the road. Magical power"."What can be installed on the car is our country's important equipment, so what if you can't bear it." In Yu Jinwei's view, driving a specially equipped car not only tests the driving skills, but also tests the driver's endurance. The more nervous you are, the more important it is. Be meticulous at all times.
After picking up the rocket "home", he rarely picked up his children from school.
The bigger the car, the harder it is to drive exponentially. Before becoming "Master Yu" who was trusted by young special-purpose truck drivers, Yu Jinwei walked a thorny road.
In 2014, more than a dozen new specially-equipped vehicles arrived at the Wenchang launch site. Yu Jinwei was overjoyed when he learned that he would be responsible for driving the first vehicle to pick up the Changqi rocket. No matter how big or small it is in the world, it seems that the first one is always the best, and "the first car" means great honor. But "everything is difficult at the beginning". After the assembly of the rocket-body road transport vehicle was completed, Yu Jinwei immediately woke up and felt the heavy responsibility on his shoulders when he saw the unimaginable huge vehicle body.
"Facing new cars and new equipment, I feel very unsure." Yu Jinwei said that in order to overcome the driving difficulties, he devoted all his energy. Every time he performed turning and reversing exercises, he had to get out of the car to check the position of the wheels, and then Return to the car to adjust.
The sun was blazing outside the car, and the air conditioner inside the car was blowing air. After going back and forth between the two places, my work clothes were dyed dark by sweat in less than half a day. In 2016, the Long March 7 rocket was successfully transported back to the launch site from Qinglan Port. While everyone was cheering and welcoming on both sides of the road, Yu Jinwei was covered in sweat while sitting in the cab.
Every time he practices thereafter, he not only requires technical proficiency, but also finds other training blind spots. In order to be able to grasp the direction in rain and fog, he put forward suggestions for modifying the routes of transport rockets and spacecrafts based on the turning characteristics of liquid hydrogen transport vehicles, which were adopted by superiors. From 150 minutes to more than 90 minutes, this is the distance that Yu Jinwei can help the Rockets.
"I didn't catch up with the birth of my eldest son." Yu Jinwei still can't let go. When his eldest son Yu Chengyao was born in 2008, he was on a space mission deep in Daliang Mountain 2,000 kilometers away. He was unable to witness the birth of his child. One of the regrets.
"The reason why dad rarely goes to school to pick you up is because there are more important guests waiting for him." After Yu Chengyao became wise, Yu Jinwei's wife Xia Xiaoyan explained to him. Now 11 years old, he often tells his younger brother stories about his father, special vehicles, rockets and space.
Behind every great achievement in the aerospace industry are ordinary people like us who have persisted in their posts for many years and completed their work meticulously and conscientiously. "I will continue to carry out future transportation tasks." Car, take the lead." Yu Jinwei said without hesitation that the Yu family's aerospace story will continue to be told.
