"The Dragon! We still have the Dragon!! In the originally empty and silent flight control hall, Yuan Limin suddenly shouted happily: "The Shenlong can fly up and dock with Tiangong No. 1, and then leave the impact area with Tiangong No. 1!" ”

Everyone was suddenly pleasantly surprised, but then their brains began to run at high speed, thinking about the possibilities, and in the decision-making area, one of the staff members said: "Shenlong is an aerospace aircraft, if it wants to fly to that distance, it must use a rocket to boost, we don't have a special booster rocket for Shenlong." ”

"We have already produced four prototypes of the special booster rocket for Shenlong, and they were originally planned to be tested at high altitudes, and now they are just being used." Yuan Limin said while calculating the specific flight parameters: "The technology of the rocket engine is very mature, so we don't have to worry about the problem of booster rockets, although the Shenlong has not actually used the booster rocket to fly, but I think it can be tried, I believe that the Shenlong can complete this task." ”

Looking at Yuan Limin, who was still doing calculations quickly, Cao Yanhua's expression was very strict, Yuan Limin's plan was very crazy, for the Shenlong as an aerospace aircraft, this was already a bit beyond its current design scope, but this seemed to be the only way now, it was better than everyone sitting helpless and waiting to die, Cao Yanhua asked in a deep voice: "Are you sure that there is no problem with the Shenlong?" ”

"Shenlong has already had flight tests in space, and you know it can do it." Yuan Limin looked at Cao Yanhua and said solemnly: "I believe in the performance of the Shenlong, and I also believe in Xia Yu's ability." And the most important thing is that we can't just give up Liu Hongliang and Yang Yi. ”

Just a little silent for a while, Cao Yanhua looked at Yuan Limin, who had a serious face, and said, "You are the person in charge of the Shenlong Project, I trust your judgment." From now on, the command center is under your sole responsibility. ”

"Understood!" Yuan Limin's answer was resolute and decisive, and because of this, the Shenlong was suddenly suspended before taking off, and Xia Yu and others saw the staff push out the booster rocket that should not have been used.

At one end of the runway at the base, two fuel-filled booster rockets have been mounted under the wings on both sides of the Shenlong, and in the cockpit, everyone is completing the inspection procedures required for take-off as quickly as possible, Xia Yu has already informed others of all the content of the mission, there is nothing to hide, for the upcoming challenges, no one here will choose to back down.

Especially Wu Degao, Du Junbao and Wu Min, they have been training with the three astronauts in Tiangong-1 for at least five years, and they are so familiar with each other, and now, Xie Dong is no longer there, leaving Liu Hongliang and Yang Yi on it, what kind of loneliness will they feel?

Wu Degao didn't know, but like Wu Degao's thoughts, Du Junbao and Wu Min, and even Wang Pengyu and Xia Yu, all the members of the Shenlong test flight team decided that they would not let the two of them go alone again.

"Command center, this is the Divine Dragon." After performing the final inspection, Wang Pengyu began to contact the flight control center: "We have completed preparations and requested liftoff. ”

"Command center received, Shenlong, you can take off at any time."

"The Dragon understands."

As Wang Pengyu's words fell, Xia Yu immediately pushed the throttle control lever, and the three turbofan engines began to roar hard, pushing the Shenlong to glide on the runway, faster and faster, faster and faster.

"Take-off speed." Wang Pengyu's reminder.

Xia Yu pulled up the elevator, and the nose of the Shenlong began to rise, and then pierced into the sky like a divine dragon under the expectant gaze of the ground personnel.

"The track information has been received and is being set." Wang Pengyu input the flight information transmitted from the flight control center into the computer, and then after Xia Yu agreed, he pressed the button of autopilot.

Shenlong automatically began to turn around and prepare to enter the scheduled orbital flight.

The Earth's rotation and revolution around the Sun itself means movement, and without careful calculation, even if your eyes look at a straight line, you will not fly to the end of that line.

In order to fly to the position of Tiangong-1 in the shortest time, Yuan Limin and other technicians in the flight control center must calculate the route that can reach the position of Tiangong-1 in the shortest time according to the position and speed of Tiangong-1 in space and the influence of the earth's rotation.

"The airspeed is Mach 6, and the thirty-second countdown is activated in the super-combustion mode." Wang Pengyu prompted. At this time, Shenlong had been flying at an altitude of 30 kilometers at this speed for 1 minute and 45 seconds, in order to wait for Shenlong to fly to the predetermined acceleration orbit.

"Scramble mode activation." As Wang Pengyu's voice fell, the autopilot Shenlong did not need Xia Yu's operation, and the tail nozzle suddenly erupted into a more huge flame than before, and the altitude and speed of the plane soared sharply. At the leading edge of the Shenlong's fuselage, the air burned due to the violent friction, wrapped in an orange-red firelight, and the Shenlong flew higher and higher with a trail of smoke that could not be seen in sight.

"The altitude is 83 kilometers, the speed is Mach 18.5, and the booster rocket starts with a three-minute countdown." Despite being pressed to his seat by the intense acceleration, Wang Pengyu still had to carry out his task, and he had to report the information on his display in real time.

After the booster rocket is activated, they will fly to Tiangong-1 according to the established trajectory. Then you can take Tiangong-1 to leave the impact area of space debris, save your colleagues and comrades-in-arms, and preserve the country's research achievements over the past few decades, no one doubts that they will not be able to complete the task, Xia Yu and others will not question the ability of the Shenlong, now they only need to wait for a while, waiting for the booster rocket to accelerate the Shenlong again.

However, just when Xia Yu and the others were confidently preparing to withstand the acceleration of the rocket, the contact from the flight control center suddenly came: "Shenlong, this is the command center, please close the rocket launch program immediately and abandon the mission." Repeat, please immediately close the rocket launch program and abandon the mission. ”
