After continuous experiments, Li Yunfei finally decided to make a set of flight equipment, it was really because the speed of flying against the wind was too slow, in terms of the current growth rate of mental power, it was difficult to break through 250 kilometers, and it was really uncomfortable to be trapped at this speed and not be able to break through, especially when I saw that the flight data showed a speed of 250 per hour, which was a bit not fast

After the wind speed has increased to nearly 70 meters per second, it has not increased much for a long time, although it is far from the theoretical upper limit, but now the growth has indeed become very slow, so the speed of the wind flight is also stuck on 250, which is really uncomfortable, so I thought of the flight equipment with the help of ion thrusters, but from the high-power repulsion field aircraft system on the medical transport plane, I got inspiration, so I abandoned the ion thruster, A more efficient propulsion system was activated.

The treatment transport plane uses such an extremely efficient thruster, which is why it has such an amazing carrying capacity. Li Yunfei was also deeply inspired, and made a miniature thruster, of course, it is actually reduced countless times, this thing may take a long time for others to do experiments, and carry out special modification and verification, but Li Yunfei's subtle operation of thinking power and perception is not convenient, and it is completely easy to draw a gourd to make, so he quickly made a limit of the reduced version of the propeller experiment.

It was only after a few simple experiments that a complete data was obtained. The diameter is 3.3 cm, the thickness is 0.6 cm, and the weight is 40 grams. Only a sufficient current needs to be added to generate thrust, with a limit value of up to 50 kg.

In fact, the power consumption is not very large, a nuclear reactor used by a machine gunner can provide 10 thrusters to provide energy far from it, as for how long it can be provided, if it is newly added nuclear fuel, then it will be used for six or seven years.

However, that thing is really a bit big, dozens of kilograms big, and it always makes people feel that it is not very safe, so Li Yunfei still uses a superconducting energy storage device, which is small and lightweight, and it is also very safe, just a disc with a diameter of fifteen centimeters and a thickness of only three centimeters, and the mass is only 1.5 kilograms.

The thing is light, but the use time is much shorter, if all 10 thrusters are used, when the full power output, it will last for more than ten hours at most. Of course, Li Yunfei's storage space is so large that he can carry several standard batteries with him, so this superconducting battery is completely sufficient, and it is always unsettling to put a nuclear reactor on his back, even if it has been verified that it is safe, but Li Yunfei still doesn't want to use that thing.

Four thrusters are mounted on the feet, two on the palms of the hands, one on the left and right shoulders, and one on the front chest and back. Of course, the purpose of such scattered installation is to be able to adjust the attitude in the air, and the maneuverability is stronger, although he can maneuver against the wind, but when the speed is too fast, the maneuver against the wind is weak, this time Li Yunfei is trying to break through the sound barrier of supersonic flight.

So the defensive armor made has also been transformed, the previous set of 6 mm accurate spar armor, was easily penetrated by the machine gunner's gun, so it is also the opportunity to redo a set of important parts of the defense of more than 10 mm, can block the impact of two or three bullets fired by the machine gunner, as long as there is a time buffer, you can also instantly activate the self-repair function of the battle armor, with the help of the high-voltage current, flowing through the armor, quickly and quickly self-repair, so as long as the armor is not blown up on the spot, don't worry too much.

Thanks to some of the technology of the machine gunner's production line, the new armor can be made flawlessly, and the seams can be said to be unable to even get air. In fact, with the production line of the machine gunner's power armor, it was still possible to add some power assistance systems to the new armor, but considering that the energy consumption after adding the power system was greatly increased, and the sensitivity would also decrease a lot, Li Yunfei still canceled the power system.

The appearance looks a bit similar to Iron Man's suit, of course, the materials are different, and there are not as many weapon systems as Iron Man, or there is no rain weapon system at all, and there is no power assist system like Iron Man.

The reason why Li Yunfei did this, of course, is because the reaction speed of the power system can't keep up with his movements, so it's better not to use it, as his strength grows agile in the future, the speed will be faster, and the power system is not good, and it also adds a lot of energy consumption.

It was precisely because of the lack of the power assistance system and weapon system that Li Yunfei made this set of battle armor was extremely lightweight, with a total weight of only twenty-five kilograms.

Although it hasn't been tested yet, it should be no problem to surpass the steel suit in terms of flight speed alone, and the defense will be higher, mainly because the defense strength of the spar is too high, and it also has a very powerful self-repair function.

……

It has been a hundred and twenty days since I came to this world, and today the weather is sunny and the wind is beautiful, which is suitable for the first flight test of the flight armor, but this time it is preparing for supersonic flight, so I deliberately chose a day with excellent weather conditions to try. When the sun had just risen, Li Yunfei was equipped with the flight armor that had taken two days to build, and stood on the roof of the building that would only be in the command center.

"Sir, don't you really need me to help control the propulsion system?" Before the test flight, Xiao Wei, who was carried in the armor, asked again.

"No, you just have to record all kinds of data...... By the way, how did you change your name today? ”

"Because you are now, scientist, inventor!

"Well, I'll just think you're complimenting me."

"Yes, I'm just complimenting sir!"

"Okay, then, let's start experimenting!"

Everything is ready, Li Yunfei finally activated the thrusters, the first drive is the four thrusters under his feet, the peak output is only 200 kg of thrust, for Li Yunfei, who is used to flying, he has no feeling at all, and the acceleration of 2 G, for Li Yunfei there is no feeling at all, so the two thrusters in his hand are also activated at the same time, and the acceleration has increased to 3G, although the overload does not seem to be large, but as time goes by, the speed of flight is getting faster and faster, Because the acceleration is always close to 30 meters per second.

It only lasted for more than ten seconds, and the speed had reached subsonic speed, which was still an upward flying attitude, which showed that this thrust was indeed powerful and efficient.

Of course, it's time to change the attitude of the flight, always rising vertically, maybe rushing out of the atmosphere, now it's electromagnetic propulsion, not fuel propulsion, flying out of the atmosphere is not so fun, at least now is not the time to play.

The attitude had just been adjusted to a near-horizontal direction, and the flight acceleration had increased by a quarter, flying towards the western prairie, and the speed was getting faster and faster, and after just three or four seconds, the entire battle armor shook.

Successfully breaking through the sound barrier can be said to be easy, reaching a speed that was impossible to hit no matter what you did before. After breaking through the sound barrier, Li Yunfei did not mean to stop, but continued to increase his speed, the battle armor only made a slight vibration, the entire structure was as stable as Mount Tai, and the energy system and propulsion system also appeared to be very stable, without any overload.
