Technology Bigshot

Since Alphabet completed its "ice-breaking journey" and successfully returned to the Greater China market, 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 earlier, and many news have reported them. Especially in the past three days, cmsx's space base has been moving frequently on the runway, and it can't be hidden from the satellites in the sky.

And today, the latest pictures released by Google satellites show that a snow-white aerospace transport plane appeared on the runway and the crowd like ants around it is a sign that cmsx will have new actions today.

For this test flight, "China Matrix CMSX" did not make any official announcements, but for a while, the aerospace and astronomy fields paid close attention to this matter, especially European Space Agency, SpaceX, Amazon and NASA. Large space agencies or space exploration companies.

Matrix Technology brought cmsx into the field of space exploration and was regarded by all peers as one of the most powerful competitors.

"The launch enters the final ten-second countdown, nine...eight...seven..."

The voice broadcast resounded in the working hall of the control center of the transmission tower. Dozens of staff members performed their duties, staring intently at a series of data information. Everything was in order.

Ren Hong and Liu Yuliang stood side by side, and they watched the track from the separation window, without saying a word.

On the runway, the snow-white "Arc Eagle No. 1" looks like a huge Mitsubishi cone. The edges have been smoothed, showing a striking streamlined body. Streamlined, the largest at the end, the edges and corners are relatively sharp towards the rear, and the four large engine jets at the rear are arranged in a tight "ten" shape, and the four jets are like a square rotated at an angle of 45 degrees.

"Arc Eagle No. 1" not only carried the "dual test flight" mission of the aircraft and the launch tower, but also carried a total of 41 tons of supplies inside, which will be lifted off together. The 41 tons of supplies will be sent to The "Tianzhou" at an altitude of 478 kilometers.

Obviously, this is an expression of cmsx's confidence in "Arc Eagle One", which also gives great confidence to the two astronauts on board. The 41 tons of cargo and expensive supplies worth US$6.7 billion mean that this test flight is only Xu success does not allow failure, it can be said that confidence and pressure go hand in hand.

In the cockpit, the two astronauts were silent, sweeping the densely arranged instrument buttons in an orderly manner, and after quickly finishing everything, one of the astronauts put his right hand on the side of his thigh to propel stem.

At the same time, the four nozzles of the main propulsion engine at the end of the body simultaneously shrunk by one-third in diameter.

"Three...two...one fire!!!"

Hearing the sound, the astronaut in the cockpit pushed the propulsion valve handle held tightly by his right hand forward without the slightest hesitation, and went straight to the bottom. The co-pilot was concentrating on locking the data displayed by the instrument on the pilot, 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 core energy supply system inside the "Arc Eagle No. 1" was activated, and the high-energy storage "Amethyst Crystal" with a high amount of energy stored in it crazily output high-purity energy through the energy matrix, and then transformed into The thrust of an aerospace transport aircraft.

Four jets of blue and white flames spewed out from the four jets at the end, and the three to four meter long tail flame was extremely gorgeous.

The bottom pulley of the aerospace transport aircraft is fixed to the three parallel ejection rails. In fact, when the "Arc Eagle One" was still on the ground, the main propulsion engine was still increasing its propulsion energy output. At this time, the ejection rails will carry Greater thrust than the main propeller provides acceleration for the aerospace transport aircraft.

I saw that on the runway, at the moment of ignition, when the four jets of the propulsion engine emitted blue and white tail flames,

The three parallel ejection rails intersecting with the body emit the surging sound of the air valve, and the volume of nearly 88 decibels or more is generated on the runway instantly, which can easily cause severe deafness to an adult.

The stationary "Arc Eagle No. 1" aerospace transport aircraft was instantly pulled by the ejection track and "carried" towards the direction of the launch tower. The paths of the three ejection tracks left three straight lines of white fog after the transport aircraft passed by. Under the influence of the tail propeller, the three sections of white mist merged into one section.

"Arc Eagle No. 1" has entered the curved ejection orbit of the launch tower from the ejection orbit on the horizontal runway, and the sound of the sonic boom resounded suddenly, which means that the transport plane has exceeded the speed of sound.

Under normal circumstances, professionally trained astronauts can withstand an acceleration of up to 7 to 10 g, while "Arc Eagle One" needs to complete an acceleration of 3 g from the start of take-off to the ninth second, plus this In the first process, it is necessary to complete the 90-degree tilt steering, from the horizontal plane to the relatively vertical high altitude, which has huge requirements on the physical fitness of the astronauts.

The impact of acceleration on the body is experienced by ordinary people in their daily lives. The most intuitive thing is that the elevator ascends. During this period, it will cause top lightness and heaviness. The faster the acceleration, the more obvious it is, especially for the blood circulation system of the human body. In other words, when the acceleration reaches a certain level, it will cause local severe hyperemia in the human body function, and severe ischemia in the other part. Mild impact will lead to inflexible movements, and severe cases will make limbs stiff. The high-risk level may even It will cause capillary damage and endanger life safety.

The acceleration of 3 g is not a problem for astronauts, but don’t underestimate the acceleration of 3 g. Ordinary people will have severe dizziness and nausea symptoms under the acceleration of 3 g, and the acceleration of 5 g will cause cerebral blood vessels. Severely damaged and life-threatening. Fortunately, for ordinary people, professional astronauts or pilots with excellent physical fitness and professional advanced escort suits can withstand greater acceleration.

It is worth mentioning that in today's aerospace activities, there are very few manned aircraft with 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 aircraft is not as good as before, but that today's technology is more advanced. In the past, rocket boosters or manned aircraft had to reach a certain limit to safely send astronauts into space, but today's technology is more advanced. The facilities are more comprehensive, and it is counterproductive to make the astronauts suffer a lot.

When the nose of the "Fox Eagle No. 1" turned to the sky along the launch tower, and the moment the body and the ejection track separated at the top, the acceleration of two gs had already been completed, and then the acceleration would reach three gs in the ninth second. g, and finally will accelerate to 4.3 g and then keep a steady speed and sail towards the outer space.

Going back and forth between space and the ground, or between acceleration and deceleration, are the most painful moments for astronauts. Fortunately, such pain lasts for a short time.
