Zhang Hao heard Nangong Zhi¡¯s inquiry, but did not look back. Mainly you didn't ask me directly.
The target of Nangong Zhi¡¯s inquiry is the commentator arranged by Dayang Group. These are actually postgraduate students in their internship period.
The commentator simply explained: ¡°Actually, the Star Cannon weapon system is already accumulating energy.
On the other hand, because the Star Cannon is powerful, its recoil is also large. The effects of force are reciprocal, and the star cannon and the projectile at rest bear the same force.
Therefore, during the launch process, the starry sky cannon body will retreat; and this will undoubtedly result in the power of the cannonball being unable to reach its maximum.
Once the cannon body retreats, it will lose a considerable part of its energy; in addition, the retreat of the cannon body will shorten the actual effective length of the barrel, lead to insufficient acceleration time of the cannonball, and will also reduce the firing accuracy.
Under such circumstances, accelerating in advance allows the cannon body to have a certain speed and energy, which will offset the reaction force when launched, allowing the star cannon to maximize its power.
In addition, if fired in a stationary state, the cannon body will retreat due to recoil, which will cause its orbiting speed to be lower than the minimum orbital speed and be pulled back to the ground by the gravity of the planet.
The starry sky cannon is heavy and requires a long acceleration time. Therefore, in order to prevent uncontrollable situations from happening, we can only accelerate in advance. "
Everyone nodded after hearing this. Even Nangong Zhi had to nod. Although these things feel very simple when pointed out, their importance cannot be ignored. Sometimes it is just a small oversight that leads to the failure of the entire campaign.
When the rail gun accelerated for about 17 minutes, the voice of the person in charge at the front, Huang Mingshan, came from the observation room: "The energy is 100%, ready to launch!"
The next moment, everyone saw that the rail gun that was accelerating in space and gradually trying to escape the gravity of Tianyuan Star suddenly stopped. The originally beautiful light blue plasma engine tail flame at the rear suddenly trembled and became chaotic.
As for the front of the giant cannon, nothing can be seen. There is no gushing flame like when the artillery is fired.
It was so quiet, there was not even a sound in the space. If it hadn't been for the sudden stop of the cannon, no one would have known that the starry sky cannon had just fired for the first time.
? 160 small high-power nuclear islands can be stored in one launch in 17 minutes. Everyone is eager to see how powerful it is. It's a pity that this rail gun wants to fly out of the star system. As long as the Ocean Group has some normal brains with such powerful cannonballs, they will not use them to attack planets in the galaxy casually.
A special rail gun shell weighing 50 kilograms has a designed flight speed of 500 kilometers per second!
To understand the speed of 500 kilometers per second, you can follow several astronomical figures of the current Dayang Group:
The first cosmic speed, which is the speed of gravity surrounding Tianyuan Star, is 25.3 kilometers per second;
The second cosmic speed, which is the speed of getting rid of Tianyuan Star, is about 36 kilometers per second;
The revolution speed of Tianyuan Star is 30 kilometers per second;
??The third cosmic speed, the ¡®minimum speed¡¯ of the aircraft launched from the orbit of Tianyuan Star reaches 16.7 kilometers per second. It should be noted that the so-called minimum speed is added to the revolution speed of Tianyuan Star itself. In other words, its absolute speed is ¡®30+16.7=46.7¡¯ kilometers per second.
This is still within the orbit of Tianyuan Star. If it were near Venus or even the sun, the speed would be even higher.
Then there is the revolution speed of the sun, which is 250 kilometers per second.
Now it is the fourth cosmic speed, with a minimum of 120 kilometers; including the speed of the sun itself, it is 370 kilometers per second.
In other words, rail gun shells with a speed of 500 kilometers per second can theoretically fly out of large galaxies! As long as it is launched, it should not be contrary to the revolution speed of the sun.
With a speed of 500 kilometers, it already has preliminary interstellar strike capabilities. Of course, the starry sky is vast, and at a speed of 500 kilometers per second, it would take six hundred years to cross a distance of one light-year, which is the diameter of the gravitational influence of the star system!
Six hundred years later, the target has already disappeared.
" However, if it is to attack targets such as planets, it is completely feasible. The rules of motion of the planet can be calculated.
However, no matter how powerful this rail gun is, its firing effect is indeed invisible. Even the eyes of Dongxu masters cannot capture small items traveling at 500 kilometers per second.
Soon Huang Mingshan reported to Zhang Hao: the launch was successful. Next, a brief inspection will be carried out, and nine consecutive launches will be carried out; after nine rounds, a major overhaul will be carried out. The maintenance process is expected to take a month.
&nThe airplane is not a space shuttle. Kong refers to aviation; Tian refers to aerospace. An aerospace plane can fly in the atmosphere and fight in space. This is amphibious technology!
The aerospace plane is more flexible and can take off from the ground and rush directly into space. If you take off from the ground, you only need a runway and no launch tower.
The transmission tower is technically complex, expensive, cumbersome to maintain, inefficient, and has weak carrying capacity.
In contrast, aerospace aircraft only need a runway; and the maintenance of the runway is simple. And when the aerospace plane takes off, it can use the buoyancy of the air, and its carrying capacity is beyond imagination.
If there is a space plane and the technology is mature, the cost of space transportation will be reduced from 4 yuan per gram to 4 yuan per kilogram, or even lower! The technical staff of Dayang Group have repeatedly demonstrated this.
Therefore, Zhang Hao pays special attention to aerospace aircraft.
At this time, the first aerospace plane is about to be assembled. (Remember the website address: www.hlnovel.com - Didn't finish reading?
