Since Alphabet completed its "icebreaking 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 trial of the "Arc Eagle-1" aerospace transport aircraft, many pictures taken from G satellites were circulated on the Internet earlier, and many news reports were reported. Especially in the past three days, the cmsx's space base has been frequently moved on the runway, and it is impossible to hide the satellites in the sky.

Today, the latest pictures released by G Satellite show that a snow-white aerospace transport plane appeared on the runway and the crowds of ants around her indicate that cmsx has a new action today.

During this test flight, "China Matrix cmsx" did not release any official announcement, but for a while, the aerospace and astronomy fields maintained a focus on this matter, especially large space agencies or space exploration companies such as ESA, Spaex, Amazon and NASA Nasa.

Matrix Technology has entered the field of space exploration with cmsx and is regarded by all its peers as one of its strongest competitors.

"The launch enters the countdown to the last ten seconds, nine...eight...seven..."

The voice broadcast resounded in the work hall of the tower control center. Dozens of staff performed their duties, staring at a series of data and information in a row, everything was in order.

Ren Hong and Liu Yuliang stood side by side, and the two were at the isolation entrance of the window and looked at the runway without saying a word.

On the runway, the snow-white "Arc Eagle One" is like a huge Mitsubishi cone with its outline, with its edges flattened to present a conspicuous streamline. The cross-section of the head end of the conical body is the smallest in the form of a bullet-shaped streamlined shape, with the largest end. The edges and angles are relatively clear as the rearward edges and angles are relatively clear. The four large engine jet ports at the tail are arranged in a tight "cross" shape, and the four jet ports are like a square rotating at an angle of 45 degrees.

This time, "Arc Eagle One" not only carries the "double trial flight" mission of the aircraft and the launch tower, but also carries supply materials with a total mass of 41 tons inside and will be launched together. These 41 tons of supply cargo will be delivered to the "Tianzhou" at a height of 478 kilometers.

Obviously, this is a manifestation of cmsx's full confidence in "Arc Eagle One", which also gives the two astronauts on board great confidence. The expensive supply materials of 41 tons of cargo of up to US$6.7 billion means that this test flight is only successful and not failure. It can be said that confidence and pressure are in line.

In the cockpit, two astronauts kept silent and swept the instrument buttons arranged in a orderly manner. After quickly finishing everything, one of the astronauts placed his right hand on the propulsion valve handle on the flank of his thigh.

At the same time, the four injection ports of the main propulsion engine at the end of the body were reduced by one-third of the diameter.

"Three...two...a little bit of fire!!!"

Hearing the sound, the astronaut in the cockpit pushed the thrust valve handle with his right hand tightly without any hesitation, directly to the bottom. The co-pilot was concentrating on locking the data displayed by the instrument on the driving, and said in a deep voice: "The core engine has been activated, the propulsion power has been steadily increasing, and the energy output ratio is normal..."

At that moment, the core energy supply system inside "Arc Eagle One" was activated, and the high-energy storage "Purple Source Crystal" with high energy was stored inside, and it was frantically outputting high-purity energy through the energy matrix, which was then converted into the thrust of the aerospace transport aircraft.

Four blue and white flames were sprayed out from the four ejectors at the tail end, and the tail flames as long as three or four meters were extremely gorgeous.

The bottom pulley of the aerospace transport aircraft is fixed with three parallel ejection tracks. In fact, when the "Arc Eagle One" is still on the ground, the main propulsion engine is still increasing the propulsion energy output power wildly. At this time, the ejection track will carry greater thrust than the main propulsion to provide acceleration to the aerospace transport aircraft.

I saw that at the moment of ignition on the runway, blue and white tail flames emerged from the four ejection ports of the propulsion engine, the three parallel ejection tracks that intersected with the body emitted a surging sound of air valves. The runway instantly produced a volume of nearly 88 decibels, which could easily cause severe deafness to an adult.

The stationary "Arc Eagle One" aerospace transport aircraft was instantly pulled by the ejection track and "supported" towards the direction of the launch tower. After the transport plane passed by, three straight white mists were left. Under the influence of the tail thruster, the three white mists then merged into a section.

"Arc Eagle One" has entered the curved catapult track of the launch tower from the catapult track on the horizontal runway, and the sound explosion suddenly resounded, which means that the transport plane had exceeded the speed of sound.

Normally, astronauts who have been trained can withstand accelerations of up to 7 to 10 g, while "Arc Eagle One" must complete accelerations of 3 g from takeoff to the ninth second. In addition, this process requires a 90-degree inclination steering, from horizontal to relatively vertical altitude, which has huge requirements for the astronaut's physical fitness.

Even ordinary people have some understanding of the impact of acceleration on the body. The most intuitive thing is that the elevator rises, during which time it will cause a light head and heavy feet. The faster the acceleration, the more obvious it will be. Especially for the human blood circulation system, when the acceleration reaches a certain level, it will cause serious local congestion in the human body. Another part is severe ischemia, and mild impact will lead to inconvenience in movements. Severe situations will cause the limbs to be stiff, and the high-risk level will even 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 these 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 serious damage to the cerebral blood vessels and affect life threats. Fortunately, it is just for ordinary people, professional astronauts or pilots with excellent physical fitness can withstand greater acceleration after being supported by professional advanced escort suits.

It is worth mentioning that in today's aerospace activities, few manned aircraft have accelerated more than 7 g like in the last century, and usually only maintain an acceleration of 3 to 5 g.

This does not mean that today's manned aircraft are not as good as before, but that today's technology is more advanced. In the past, rocket boosters or manned aircraft must reach a certain limit to send astronauts to space safely. However, today's technology is more advanced and the facilities are more comprehensive, and allowing astronauts to suffer huge pain is counterproductive.

When the nose of the Fox Eagle One turned to the sky along the launch tower, the moment the body and the ejection track separated at the top, the acceleration of two g had been completed. Then, the acceleration will reach 3 g in the ninth second, and finally it will accelerate to 3 g and maintain a stable speed and drive towards outer space.

Between traveling between space and the ground, or between acceleration and deceleration, are the most painful moments for astronauts. Fortunately, such pain lasts very short.
