On November 23, the long March 3B carrier rocket developed by the first Academy of China Aerospace Science and Technology Group Co., Ltd., together with the upper stage of Expedition 1, successfully put the two Beidou 3 satellites into the intended orbit in the form of "one arrow and two stars." The launch is the 107th launch of the long March 3A series of carrier rockets and the 11th launch of the series of carrier rockets this year.

In the 12 years since the launch of the first Beidou II navigation test satellite in 2007, 51 Beidou navigation satellites have been put into orbit with 37 successful launches. If you take into account the Beidou navigation test satellite launched earlier, then the long triple A series of rockets have been 41 times, escorting 55 Beidou satellites into orbit.

"double shooting in January": the Big "Labor Model" of the long March Rocket Family

Following the launch of the Beidou 3 navigation satellite on 5 November, on the morning of 23 November, the long March 3B rocket once again put two Beidou 3 navigation satellites into orbit and completed the "January double launch" at a high frequency of two launches in 18 days. Prior to this, the long three series of rockets have completed such a "feat" twice.

Because of its high orbit accuracy, many orbit choices and strong adaptability, long Sanjia series rockets have become the "exclusive train" for launching Beidou navigation satellite. Jin Zhiqiang, commander-in-chief of the long March 3A series rockets, said that the long triple A rockets have high precision in orbit, and can be launched not only by "one arrow and one star", but also by "one arrow and multiple stars". It can be used not only for the launch of standard geosynchronous transfer orbit, but also for hyper-synchronous transfer orbit or low inclination synchronous transfer orbit. During flight, the rocket can realize lateral maneuvering orbit change, multiple take-off, racemization, orientation and so on. To meet the different orbit requirements of the satellite.

As a big "model worker" in the long March rocket family, the long three Series Rockets are also the only series of rockets in China that have entered the "100 launch Club" at present, holding a number of records: in 2015, The long triple A series of rockets set a high-density launch record of seven launches in 109 days. In 2018, the long triple A series rockets successfully completed 14 launch missions, creating an annual launch record; In April 2019, the long March 3 Yiyao 59 rocket put the Beidou navigation satellite into its intended orbit, making the long triple A series the first single series of rockets to be launched more than 100 times.

"efficient Unification": there is a "knack" behind Lien Chan Lianjie

For a long time, the pace of success in the long three series of rockets has never slowed down. In the face of the situation that the development, production and launch of models with high density have become the norm, in order to make the management process more precise, the experience summed up in the model work has been effectively solidified, transmitted and applied. The model has made great efforts in the construction of fine process management system.

As a complex system engineering, space model development requires not only the close cooperation of each participating unit, but also the cooperation and smooth connection of each link and each personnel. Only in this way can we ensure that every work can be completed correctly, regularly and efficiently, and that the launch is foolproof.

"Fine process management is a set of management theories and methods formed by the integration of fine management, process reengineering, knowledge management and space practice. Its greatest advantage is that it provides a scientific and effective way. The rocket development work has been organically and efficiently unified with all links and posts. " Li Minghua, secretary of the Party Committee of the first Academy of China Aerospace Science and Technology Group, said.

"in order to better optimize and improve the on-site work flow, the model has put forward clear requirements in the aspects of process carding, data analysis, work 'double thinking', etc., and the 'one net' should be used to filter the on-site engineering process items. Use the magnifying glass to find hidden problems and hidden dangers, and do a good job of anticipating and remembering with the way of showing movies. " Chen Minkang, chief designer of the long March Series 3A rocket, said.

"Gold Rocket": the other side of success is "sweat"

With the performance of high reliability and high success rate, the long three series rockets enjoy the reputation of "gold medal rocket". Behind the successful launch, a vibrant and effective development team silently supports the growth of this type of gold medal rocket.

In order to meet the needs of the construction of the Beidou Project, the Chang San Jia series rocket development team has carried out a lot of innovative work. It breaks through dozens of key technologies represented by multi-orbital surface design technology, take-off and roll orientation, two-way high-altitude wind compensation, cold helium supercharging system redundancy and so on, and the flight reliability is improved to the level of 0.94.

The long March 3B rocket carrying out this mission continues to improve its reliability and safety: the on-arrow measurement system adds protection devices and protection means to improve the reliability of data acquisition; The safety of ground equipment is further strengthened and the safety of use is improved by upgrading and optimization of ground equipment.

In recent years, the high-density launch of the long Sanjia series rockets has gradually become the norm. Although the process optimization and rocket launch preparation time have been greatly shortened, the development team still travels at the launch site for a long time. Key team members, who travel an average of more than 200 days a year, often joke that returning to Beijing is called a "business trip" and that the launch base is their "second home".

Zhu Pingping, who serves as the conventional power command of the rocket, suddenly felt unwell during a conventional propellant filling process. In order not to affect the progress of his work, he stuck to his command post in pain and kept an eye on the amount of data on the display screen. After the injection, he found that the amount of injection was a little lower than the required value, and his nerves suddenly tightened. He quickly interpreted and analyzed the data, recalculated the amount of attention, and accurately completed a series of crisis handling actions. Only a few drops of painful sweat that accidentally fell from his forehead told of the suffering he was going through.

After intense discussions it was considered that the results of the increase would meet the needs of the mandate and would not affect the follow-up work. Later, the rocket was launched on time and accurately into orbit, but Zhu Pingping was admitted to the hospital because of acute intestinal obstruction.

"We pursue not only the perfection of the results, but also the perfection of the process." Jin Zhiqiang, commander-in-chief of the long March 3A series of rockets, said it was this persistence that supported the team's progress towards a higher goal.
