Chapter 521: : Launch into the sky】

Since Alphabet completed its "ice-breaking journey" and successfully returned to the Greater China market again, many things have become more free.
Just as the "China Matrix cmsx" is about to conduct the first test flight of the "Arc Eagle One" aerospace transport aircraft, many pictures from Google satellites have been circulated on the Internet and many news have been reported. Especially in the past three days, cmsx's space base has moved frequently on the runway field, which is impossible to hide from the satellites in the sky.
Today, the latest pictures released by the Google satellite show that a snow-white aerospace transport aircraft appears on the runway and the ant-like crowds around it indicates that cmsx has new actions today.
During the test flight, the "China Matrix cmsx" did not issue any official announcements, but for a while, the aerospace and astronomy fields kept focusing on this matter, especially ESA, spacex, Amazon, and NASA. Large space agency or space exploration company.
Matrix Technology brings cmsx into the field of space exploration and is regarded as one of the strongest competitors by all colleagues.
"The launch counts down to the last ten seconds, nine... eight... seven..."
The voice announcement resounded in the work hall of the transmission tower control center, and dozens of staff members performed their duties, staring at a series of data messages, everything was in order.
Ren Hong and Liu Yuliang stood side by side. The two of them watched the runway at the isolated window, and said nothing.
On the runway, the snow-white "Arc Eagle One" is like a huge Mitsubishi cone-like outline, the edges are flattened, showing a striking streamlined body, the cross section of the cone-shaped body is the smallest in the shape of a bullet. It has a streamlined shape with the largest end, and the rearward angles are relatively sharp. The four large engine nozzles at the rear are arranged in a tight "cross" shape. The four nozzles are like a square rotated by 45 degrees.
This time, "Arc Eagle One" not only carried the "dual test flight" mission of the aircraft and the launch tower, but also carried the supply materials with a total mass of 41 tons. The 41 tons of supply goods will be sent to the sky. The "Tianzhou" at an altitude of 478 kilometers.
Obviously, this is cmsx's full confidence in the "Arc Eagle One", which also gave the two astronauts on board great confidence. The 41 tons of expensive supplies worth 6.7 billion US dollars meant that the test flight only To be successful and not to fail is to walk with confidence and pressure.
In the cockpit, the two astronauts were silent, sweeping on the densely arranged instrument buttons in an orderly manner. After everything was done quickly, one of the astronauts put his right hand on the thigh flanks and pushed forward. Valve handle.
At the same time, the four injection ports of the main propulsion engine at the end of the fuselage were reduced by one-third at the same time.
"Three...two...single fire!!!"
The astronaut in the cockpit heard the sound, and without any hesitation, pushed the propulsion valve handle held tightly with his right hand forward, directly to the bottom. The co-pilot was concentrating on locking the data displayed by the driving instrument, and said in a deep voice: "The core engine has been activated, the propulsion power is steadily increasing, and the energy output ratio is normal..."
At that moment, the internal core energy supply system of "Arc Eagle One" was activated, and the high energy storage "purple spar" with high energy reserves inside it crazy output high-purity energy through the energy matrix, and then transformed it into The thrust of the aerospace transport aircraft.
The four jets at the end of the jet suddenly ejected four blue and white flames, and the tail flames of three or four meters long were extremely gorgeous.
The bottom pulley of the aerospace transport plane is fixed to the three parallel ejection tracks. In fact, when the Arc Eagle 1 is still on the ground, the main propulsion engine is still increasing its propulsion energy output power wildly. At this time, the ejection track will carry More thrust than the main thruster provides acceleration to the aerospace transport aircraft.
I saw on the runway, at the moment of ignition, while the four jet nozzles of the propulsion engine emitted a blue-and-white tail flame, the three parallel ejection trajectories that intersected with the fuselage made the surging sound of the air valve. Nearly 88 decibels or more, this can easily cause severe deafness in an adult.
The stationary "Arc Eagle One" aerospace transport was instantly pulled by the ejection track and "held" toward the launch tower. The path of the three ejection tracks left three straight white fog after the transport plane passed by. Under the influence of the tail thruster, the three sections of white mist merged into one section.
"Arc Eagle One" has entered the curved ejection orbit of the launch tower from the ejection orbit on the horizontal runway, and the sonic boom suddenly resounded, which means that the transport plane has exceeded the speed of sound.
Under normal circumstances, professionally trained astronauts can withstand accelerations of up to 7 to 10 g, and "Arc Eagle One" needs to complete an acceleration of 3 g from the start of take-off to the ninth second, plus this In one process, a 90-degree tilt angle steering must be completed, from the horizontal to the relatively vertical high altitude, which has huge requirements for the physical fitness of the astronauts.
The impact of acceleration on the body is experienced by ordinary people in life. The most intuitive thing is that the elevator rises. During this period, it will produce top-light and heavy feet~EbookFREE.me~ The faster the acceleration, the more obvious, especially As far as the blood circulation system of the human body is concerned, when the acceleration reaches a certain level, it will cause severe local congestion in human body functions. The other is severe ischemia. Mild effects will cause inconvenience. The limbs are stiff, and the high-risk level may even damage the capillaries and endanger life.
An acceleration of 3 g is not a problem for astronauts, but don’t underestimate the acceleration of these 3 g. Normal people will have severe dizziness and nausea under the condition of an acceleration of 3 g, and an acceleration of 5 g will produce cerebral blood vessels. Severe damage and threat to life, but for ordinary people, professional astronauts or pilots with excellent physical fitness can withstand greater acceleration after being protected by professional advanced suits.
It is worth mentioning that in today's aerospace activities, few manned aircraft have an acceleration of more than 7 g as in the last century, and usually only maintain an acceleration of 3 to 5 g.
This is not to say that today’s manned vehicles are not as good as before, but that today’s technology is more advanced. In the past, rocket boosters or manned vehicles had to reach a certain limit to safely send astronauts to space, but today’s technology is more advanced. With more comprehensive facilities, it would be counterproductive for the astronauts to endure tremendous pain.
When the nose of the "Fox Eagle One" turned to the sky along the launch tower, and the body separated from the ejection track at the top, the acceleration of two g had been completed, and then the acceleration of the ninth second would reach three. g, it will accelerate to 4.3 g and then maintain a steady speed and drive into outer space.
Traveling between space and the ground, or between acceleration and deceleration, is the most painful time for astronauts. Fortunately, such pain lasts for a short time.
