Compared to a rocket motivation ability model, 8 rocket motivations made of silver and steel were successfully manufactured.

After installing the motive in the stern of the "Richidong", a huge problem immediately arose.

The thrust of the rocket motor is relatively large, but the fuel drunk is not less than the turbofan engine, and it is even more terrifying!

You know, a 6,7oo ton heavy launch vehicle, most of which is filled with fuel. Especially after the rocket is launched, the 3,4oo tons of fuel in the first stage rocket can be "drunk" by several rocket motives in more than 2oo seconds, and it is not an exaggeration to describe the rocket motive as "oil drinking monster".

The 8 engines installed in the tail of the "Lidong", assuming that one ton of hydrogen and oxygen are "drunk" every second, and if 1ooo tons of water are decomposed at a time in the morning, the consciousness of 3oo magazines will be consumed, and it can only maintain less than 2o minutes of operation, which is really a bit inefficient.

Moreover, in contrast to the 8 rocket motives, there are 8 huge fuel tanks, and each time the fuel is refilled, the 8 tanks have to be filled repeatedly, which is really troublesome.

In order to save these troubles, Tianming thought of a better solution.

That is, to have 8 rocket engines share the same combustion chamber.

The operation method is also very simple, first made a large hydrogen and oxygen tank, with a volume of 12oo cubic meters! It can be filled with 8oo cubic meters of liquid hydrogen and 4oo cubic meters of liquid oxygen, and through a valve device to control two pipelines, hydrogen and oxygen in a ratio of 2:1 will enter a 1o cubic meter large combustion furnace along the two pipelines, mixed combustion.

The high-temperature and high-pressure air flow in the combustion furnace will pass through eight silver-steel pipes and eject from the eight rocket motors connected to the pipes, generating a back-impulse that pushes the "Lidong" forward.

A giant hydroxide tank, a valve. With one burning furnace and 8 engines, Tianming has simplified the power plant of the Lidong to the extreme!

After a major overhaul of the stern, 12oo tons of fresh water was also broken down into hydrogen and oxygen fuel by Tianming, and the new power unit was ignited and tested.

"Boom! Rumble! Rumble! ”

Eight rocket engines erupted a 5o meter-long pencil cone of flames, and the hull of the ship shook violently, and the blue stars on the ship appeared in surprise. The ship seemed to move, faster and faster, faster and faster, as if flying, so fast that they opened their mouths wide and were utterly shocked.

In fact, this is not the first time they have been shocked, when the power plant of the Lidong was still 2oo strings of sugar gourds, they also felt this feeling of speed. But this time it was obviously a little stronger than the last time, especially when they saw the 8 blue pillars of light at the stern of the boat, many blue star people even knelt on the ground and shouted miracles.

"Voyage 28 knots, the rocket lasts for 15 minutes, the total thrust of the 8 rocket engines is about 2ooo tons, and the total horsepower is 27ooo horsepower, which is about equal to the power of 14o mini motors. Except for the exaggerated degree of fuel drinking, there seems to be no problem. Tianming muttered to himself.

At this time, there was a commotion in the cabins of the second, third, and fourth floors of the ship.

In a panicked scream, countless Blue Star people crowded the entrance of the building, rushed up from the lower cabin, and when they ran to the deck, they were already sweating profusely, as if they had been fished out of the water.

"It's hot. It's hot to death! ”

"Master, is the ship on fire, it's so hot down there!"

"Almost, almost I died of heat down there!"

"What's going on?" Tianming was taken aback, and ran to the lower cabin to take a look, a heat wave rushed towards him, and the temperature was conservatively estimated to be more than 8o degrees. Flashing into the ability space, and then probing into the power room near the stern motor, I was immediately startled, and the temperature exceeded 5oo degrees.

"Not good! Hydrogen-oxygen tanks and combustion furnaces are placed between the second and third decks of the stern. After the fuel in the combustion furnace burned violently, all the excess heat remained in the power compartment, the shell of the power compartment was made of black iron material, the heat insulation was poor, the temperature in the cabin rose sharply, and the terrifying heat generated by 12oo tons of fuel, the ship did not immediately catch fire and burn, which was really a kind of luck. ”

After taking emergency measures to lower the temperature in the power compartment, Tianming thought of several methods, and finally thought of a way to solve the problem of high temperature generated by the combustion furnace.

The first is temperature insulation, Tianming covered the inner wall of the power compartment including the hydrogen and oxygen tank and the combustion furnace with a thick layer of insulation material, and then, outside the combustion furnace, added a cooling device - a large water tank, which Tianming connected with the water storage tank in the first fresh water tank of the Lidong.

In this way, under the cooling of more than 13oo tons of fresh water, most of the heat generated by the combustion furnace during the combustion process will be absorbed by this cold water.

This brings a benefit: the Blue Star people on the ship will be able to use hot water in the future! You can drink hot water and take a hot bath, which can greatly improve the quality of life.

This time, Tianming did not adjust the fuel flow control valve of the hydrogen and oxygen tank to the maximum, but adjusted it to one-tenth of the size, so that a tank of fuel can be used for more than 2 hours.

This time, the length of the tail flame sprayed by the tail of the Lidong motive was obviously much shorter than just now, only 15 meters long.

Because the resistance of the water is very small, the resistance of the 15,000-ton ship in the water is only about 15o tons, and the thrust of the rocket is more than 2oo tons, which is enough to propel the Lidong forward, but the degree is slightly slow, about 4 or 5 knots, which is slightly faster than the degree of human walking.

"It's still too slow, but if it's fast, the fuel won't burn for long, so what can I do?"

4o minutes after the rocket engine was started, Tianming measured the water temperature in the fresh water tank, and it reached 9o degrees, and all 13oo tons of water were heated to 9o degrees! This is really too exaggerated, if it continues to boil, in less than an hour, won't all this water have to boil?

"I can't do it like this! It seems that if we still have to install a steam turbine on this ship, and use the heat generated by the combustion furnace, I don't believe that this ship can't run fast for a long time! ”

There was no way, Tianming could only open up another fresh water tank opposite the fresh water tank, and fill it with 1ooo tons of fresh water, this fresh water tank is a cold water tank. Connected to the furnace is naturally a hot water tank. Of course, the cold water tank and the hot water tank are still connected by water pipes, and the hot water in the hot water tank can also enter the cold water tank, but the degree of access is limited. Not enough to heat cold water to the point where it is as hot as hot water, the water temperature in the cold water chamber will not exceed 55 degrees Celsius.

……

Because I have been busy with messy things in the past few days, I didn't have time to deal with many things on the ship, and it took 4 or 5 days for Tianming to finally complete everything.

First of all, the cleaning system of the Lidong was brought out.

Tianming connected the water pipes to all the places that needed to be connected in the cabin on the fourth floor of the Lidong, including 32 public toilets, 8 bathing rooms, and 8 laundry rooms. composition of the water supply system. It can supply both hot and cold fresh water at the same time, as long as the switch is turned left and right, which is very convenient.

Countless brain cells died, and Tianming also made a sewage collection system, a thick sewage pipe to produce domestic sewage from the people on board. All of them are concentrated in a large cesspool at the bottom of the warehouse. At the bottom of the cesspool, there are three suction pumps, which are connected to the three diesel pumps located in the diesel engine room on the first floor, and if they work at the same time, in 3 hours, 2ooo tons of domestic sewage can be passed through two large holes on both sides of the guò hull. It's all pumped into the sea......

After the cleaning system was made, Tianming immediately issued an order: it is forbidden to defecate openly on the deck, and violators will be given thirty lashes!

……

After dinner, Poch, a member of the fishing team, planned to go to the side of the boat in the middle of the deck to take a dip.

This is a fixed toilet spot, which is convenient for many people, and even Mi Ma has put a few buckets of water here in order to wait for them to go to the toilet. Wash the feces out into the sea and wash your butt and hands again.

Pochi comes here once a day.

The ship was strange, there were no special toilets, and there were no manure pots, which made Pochi, who had been a sailor for a while, very uncomfortable.

Of course, the ship was clean. Especially in the cabin where he lived, every time he walked in, he would wipe the soles of his feet so that the floor would not be stained by some sweaty footboards.

Floors with a special friction feel. It feels very comfortable to step on. The living conditions of this ship were far better than all the ships that Poch had been on before, especially the steel frame bed that belonged to him, and he was particularly satisfied...... In an environment like this, only the captain is qualified to live in it, right? Pochi said to himself.

Just as he was about to take off his pants, a team of law enforcement officers arrived and stopped him.

"No open defecation on deck!" The law enforcement officer said to him with a dark face.

"Why don't you let me be on deck? I'm going to. ”

"to 'cesuo' lira, you can't on the deck, and if there is a random puller, whip 3o times!" The law enforcement officer flicked the whip in front of him.

"Where's 'cesuo'?" What is cusuo'? ”

The captain of the law enforcement team gestured to a soldier next to him, and soon Pochi was taken to a bathroom on the second floor of the cabin with the word "toilet" written on it, and was ordered to take off his pants and squat on a toilet.

"Hurry up and pull, remember to flush when you're done."

"How does this pull? I can't pull it out, what does it mean to flush? Pochi said with a look of embarrassment.

"How you usually pull, how you pull now! You'd better hurry up, there are a lot of people who want to learn to use 'cesuo', and if you can't pull it out after a while, I'll have to arrange for someone else to learn. The soldier said.

"I pulled it out, I made it!" At this moment, a cheer came from the side.

"No, don't, the hole in this bucket is too small, I'll die if I squeeze it in." There was another frightened voice next to him.

"Your chance is gone, next!" A cold, impatient voice rang out.

Puff~! After holding it for a while, the purple and blue Pochi with a suffocating face finally pulled the stool out, and an unprecedented feeling came up: I did it! I did it! I got on 'netbsp; Soon, Pochi, who overcame his fear, pulled out all the inventory, and today's task was completed.

Whoa, whoa, whoa! Pulling a rope, the water in the toilet tank flushes the feces without a trace, much to Boqi's amazement, he had never seen anything so magical.

Something like this has been happening these days, and this kind of thing of open defecation on the deck, after the law enforcement team whipped dozens of people, has never happened again.
