Armor Frenzy

Four consecutive sets of booster rockets were exhausted in less than twenty minutes, and after the feeling of pushing back completely disappeared, the battleship threw away the last set of booster engines, and the appearance was restored to its original shape. At this time, only the main engine was left to propel the battleship, and the acceleration effect was far less obvious than that of the rocket.

Huang Bowo breathed a long sigh of relief in the chair: "Okay, the attendant stays, the others are free to move around, Ye Han comes with me!"

After speaking, Huang Bo stood up and tilted his head at Ye Han with a smile.

There is no gravity in the universe, and with the existing technology of mankind, it is impossible to install any artificial gravity equipment on 024.

But the people in the battleship can't always float around, so the military thought a little way, all the floors in the battleship are magnetic materials, the cabin partitions and ceilings are non-magnetic materials, and then all the crew are equipped with magnetic Shoes, the crew can walk around in the battleship.

However, magnetic shoes are not gravity after all. Walking with this thing is awkward. Many people would rather float around in a battleship than wear this thing.

Ye Han just got on the ship, and he came in a hurry. He didn't have time to get the magnetic shoes. After unbuckling the seat belt, he immediately floated up. He immediately grabbed the chair and flew to the cabin door lightly.

Seeing this, Huang Bo laughed, and simply took off his magnetic shoes and floated off the bridge with Ye Han: "Time flies so fast, I still remember when I first met you, your kid was still a lieutenant, it's only been a few years. Time is on par with me."

"Do you still remember me?" Ye Han was very surprised.

"Why don't you remember?" Huang Bo looked back at Ye Han, "I was the one who wanted you into the fleet at that time."

"Yes, I always remember." Ye Han said, "If it weren't for you, I wouldn't be able to wear power armor."

"That has nothing to do with me. If you don't work hard, no one can help you." Huang Bo waved his hand, suddenly reached out and grabbed the handrail fixed on the bulkhead, parked outside the captain's room door, and pressed his thumb beside the door. , the hatch slid open silently.

Huang Bo floated into the captain's room: "Come in, you're welcome."

Ye Han tapped lightly and slowly floated into the captain's room.

In the weightless environment, there is no difference between sitting and not sitting. Huang Bo was not polite at all, and handed a document directly to Ye Han: "I came to you to talk about the Marine Corps."

Ye Han wondered: "Isn't the appointment already made?" The trial sailing of the battleship requires the presence of all members, and the Marine Corps is no exception.

Huang Bo sighed: "It's been made a long time ago, but he doesn't have this blessing."

"What's wrong?" Ye Han was secretly surprised.

"With space blindness, expedition missions are definitely not expected." Huang Bo said.

Ye Han twitched the corners of his mouth: "Too unexpected, I didn't prepare at all, I just came up with my wife... Captain, doesn't the expedition fleet have to be voluntary? I haven't applied for it at all, how can I be transferred to the fleet? "The grievances in his heart are like a surging river, endless.

The order has been issued, no matter how reluctant it is, there is no way to do it, but I can only bite the bullet, but the reason should always be asked clearly, right?

Huang Bo replied: "There are not many qualified marines, and even fewer have rich combat experience like you, so the above sent you here, and there is really no one to be found."

Ye Han secretly scolded fart, the marines were all trained by Lao Tzu, how could he not even be able to find a qualified one?

Huang Bo seemed to see that Ye Han's face was wrong, and explained again: "There are soldiers, but there are no suitable officers."

Speaking of this step, Ye Han could only sigh: "What else can I say? This walk is five or six years..."

Huang Bo's eyes widened, his face stunned: "Five or six years? Who told you?"

"Isn't it?" Ye Han was stunned. "That's what they said. I heard that it was said during the meeting above."

"It's a fart." Huang Bo said indifferently, "I know this, let me tell you this, the person who said this is a second knife who doesn't understand at all, and doesn't understand the current aerospace technology at all. It didn't count, just told the first brother that it took two and a half years, three and a half years, and he almost became a major general because of this."

Ye Han was so shocked that he couldn't close his mouth: "How long is five or six years? I heard that it took more than three months for a battleship to fly from Earth to Mars. According to this calculation, it really took more than two and a half years to fly to Jupiter!"

"That's your calculation wrong!" Huang Bo said unceremoniously, "You all came out of the crash course, and you only learned a little bit of fur, so you don't have the same calculation at all."

"How long does it take?" Ye Han asked eagerly.

He didn't care about the major general downgrading to the colonel, only the exact time it took for the fleet to go back and forth.

"It sounds complicated, I'll do the math for you." Huang Bo stretched out a hand and flexed a finger, "We didn't choose the time of our departure randomly, it was planned to start from the moon at this time and place. Yes, first of all, for Earth, the fleet comes with the speed bonus given by the moon, understand this?"

In order to increase the initial speed, the military has tried a lot. Even if he is a real captain in the sky, he has to be the same number to make it clear.

"Understood, the speed at which the moon revolves around the earth." Ye Han nodded ~www.readwn.com~ Yes, this is it, about a kilometer per second. "Huang Bo flexed his second finger," and then the booster rocket accelerated. I don't need to say this, right? "

Ye Han asked curiously, "What is this speed?"

Although the duration of the booster rocket is short, it can provide a higher initial speed for the warship, which shortens the acceleration time of the main engine. The higher the initial speed, the shorter the time required to fly to Jupiter.

"I can't say it right now, but I can tell you that with the rocket boost and the main engine propulsion, the fleet's speed when it reaches the earth is about twelve kilometers per second."

Ye Han nodded: "It's enough."

"Where is this enough?" Huang Bo flexed his third finger, "After flying close to the earth, the fleet has to use the gravitational slingshot effect to accelerate again."

"Can you use a gravitational slingshot from the moon?" Ye Han was surprised.

Before Ye Han was transferred to the training team, he knew about the gravitational slingshot, but he never understood what the gravitational slingshot meant.

Just think about it, the spaceship is pulled towards the planet by the planet's gravity, just like a stone falling to the ground. It is not difficult to understand that there is a speed bonus, but when leaving the planet, it is not the same as being pulled by the planet's gravity, and the speed that has been obtained is not changed. Back to the planet?

It was not until he came into contact with astronautics that he knew that what he thought was too simple.

If the planet is stationary, the spacecraft cannot use the planet's gravitational acceleration to accelerate, but one of the most basic definitions of physics is that absolute motion is relatively static, and the planet always revolves around the sun!

While the spaceship is approaching the planet, the planet is running continuously. The spaceship flies behind the planet. The planet's gravity is like an invisible rope pulling the spaceship. The spaceship is pulled by the planet to speed up. So the spaceship gets the speed bonus granted by the planet.
