During the first flight test of the "Arc Eagle No. 1" air and space transport aircraft of the "China Matrix CMSX", many pictures taken by Google satellites were circulated on the Internet earlier, and many news reports were made. Especially in the past three days, CMSX's space base runway has been moving frequently, and it is impossible to hide the satellites in the sky.

And today, the latest pictures released by Google Satellite show that a snow-white air and space transport plane appeared on the runway and the ant-like crowd around it is a sign that CMSX has a new move today.

There was no official announcement from the "China Matrix CMSX" for this test flight, but for a while, the aerospace field and the astronomy field have maintained a focus on this matter, especially large space agencies or space exploration companies such as ESA, SpaceX, Amazon and NASA.

Matrix Technology's entry into the field of space exploration with CMSX is regarded as one of the strongest competitors by all peers.

"The launch goes into the last ten seconds countdown, nine ...... Eight...... Seven ......"

The voice broadcast resounded in the work hall of the transmission tower control center, and 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 the two of them were at the window separation and watched the runway without saying a word.

On the runway, the snow-white "Arc Eagle No. 1" is like a huge Mitsubishi cone-like outline, the edges are smoothed, showing a striking streamlined body, the cross-section of the head of the conical body is the smallest in the form of a bullet, the end is the largest, the edges and corners are relatively distinct the further back, the tail of the four huge engine jets present a tight "ten" shape arrangement, the four jets are like a square that rotates at an angle of 45 degrees.

This time, the "Arc Eagle No. 1" not only carried the "double flight test" mission of the aircraft and the launch tower, but also carried a total mass of 41 tons of supply materials into the air together, and the 41 tons of supply cargo will be sent to the "Tianzhou" at an altitude of 478 kilometers.

Obviously, this is a sign of CMSX's confidence in the Archawk 1, which also gives great confidence to the two astronauts on board, and the 41-ton cargo of up to $6.7 billion in expensive supplies means that the test flight can only succeed and not fail, which can be described as confidence and pressure.

In the cockpit, the two astronauts were silent, orderly sweeping on the densely packed instrument buttons, and after quickly getting everything done, 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 nozzles of the main propulsion engine at the end of the fuselage were simultaneously reduced by a third of the caliber.

"Three...... Two...... A little fire!! ”

The astronaut in the cockpit heard the sound, and without the slightest hesitation, he pushed the thrust valve handle held in his right hand forward, directly to the bottom, and the co-pilot was engrossed in 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 "Amethyspar" with high energy storage in it was frantically outputting high-purity energy through the energy matrix, and then converted into the thrust of the aerospace transport aircraft.

The four jets at the tail suddenly erupted four blue-white tongues of fire, and the tail flames that were three or four meters long were incomparably gorgeous.

In fact, when the "Arc Eagle No. 1" is still on the ground, the main propulsion engine is still frantically increasing the propulsion energy output power, at this time, the ejection track will carry more thrust than the main thrust to provide acceleration for the aerospace transport aircraft.

I saw that on the runway, at the moment of ignition, while the blue-white tail flames came out from the four jets of the propulsion engine, the three parallel ejection tracks that intersected with the body emitted the surging sound of the air valve, and the volume on the runway was instantly as high as nearly 88 decibels, which can easily cause severe deafness in an adult.

The stationary "Archawk No. 1" air-space transport plane was instantly pulled by the ejection track and "supported" in the direction of the launch tower, and the path of the three ejection tracks left three straight white fog after the transport plane skimmed, and under the influence of the tail thruster, the three white fogs then merged into one section.

The "Archawk 1" has already entered the curved ejection track of the launch tower from the ejection track on the horizontal runway field, and the sonic boom suddenly resounds, which means that the transport aircraft has exceeded the speed of sound.

Under normal circumstances, professionally trained astronauts can withstand acceleration of up to 7 to 10 g, and the "Arc Eagle 1" has to complete an acceleration of 3 g from takeoff to the ninth second, plus this process needs to complete a 90-degree inclination turn, from horizontal to relatively vertical altitude, which has huge requirements for the physical fitness of astronauts.

The impact of acceleration on the body is experienced even by ordinary people in life, the most intuitive is the elevator rise, during which it will produce lightheadedness, the faster the acceleration is more obvious, especially for the human body's blood circulation system, when the acceleration is fast to a certain extent, it will make the human body function produce local severe congestion, the other is severe ischemia, the mild impact will lead to inflexible movements, severe cases will make the limbs stiff, and the high risk will even make 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 under the acceleration condition of 3g, and the acceleration of 5g will produce serious damage to the cerebrovascular blood vessels and affect life.

It is worth mentioning that in today's aerospace activities, few manned vehicles have accelerated beyond 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, and in the past, rocket boosters or manned vehicles had to reach a certain limit to send astronauts safely into space, but today's technology is more advanced and the facilities are more comprehensive, and it is counterproductive to make astronauts suffer greatly.

When the nose of the "Fox Eagle 1" turns to the sky along the launch tower, the moment the body and the ejection track are separated at the top, it has completed the acceleration of two G, and then the acceleration will reach 3 G in the ninth second, and finally it will accelerate to 4.3 G and then maintain a stable speed and sail towards outer space.

Traveling between space and the ground, or between acceleration and deceleration, is the most painful moment for astronauts, but fortunately, the pain lasts for a short time.
