After the jujube entered the menu of the sailors' crew, those who suffered from a cold were cured the next day, and there were no more cases of cold and fever.

Three days later, the unprotected survival was successful, and everyone on the other 5 warships finally put their minds at ease and took off the filter suit on their bodies, touched the air of this planet with all their hearts, took a deep breath, and spit out a breath of turbid air after half a minute.

According to one study, animals tend to become gigantic if the oxygen content of the air is too high, such as the Earth's dinosaur age, when the Earth's oxygen content was close to 25%.

Blue Mercury has nearly 40% more oxygen than the Earth, and it is not uncommon for whales to appear hundreds of meters long. When the earthlings arrived on this planet, they had to reduce their breathing rate to 2/3 of the previous one in order to adapt.

……

After the high-altitude airship was taken out, under the control of two controllers and lifted by air buoyancy, the giant airship with a length of more than 50 meters continued to rise, and finally the suspension height was fixed at an altitude of 15,000 meters.

"The planet's atmosphere is 1.5 times thicker than Earth's, and if you put hydrogen in an air bag, the airship can rise to an altitude of 30,000 meters, so you can see every move within a radius of more than 500 kilometers." The expert who controls the airship.

"It's still not as good as satellites, if you have a complete satellite navigation system, you can see any corner of the planet clearly." Liu Haiyang sighed.

Tianming looked up at the sky and looked at the huge white airship, which was so conspicuous! If this airship can see others, then others can see it at a glance - Blue Mercury has no air pollution, 10,000 meters in the air, and the air is so pure that it can sometimes see fleets hundreds of kilometers away. Of course, this is in the absence of clouds.

"That strange thing flies so high." The people of Blue Star talked a lot, and from time to time they looked up at the white airship in the sky, and their curiosity was aroused.

Liu Haiyang said to Tianming: "Commander, it's been five days since I came to this planet. Give us some assignments. ”

Tianming said: "Mission? There are no tasks yet, just send drones to patrol the vicinity a few times. ”

The six warships brought a total of more than a dozen unmanned aerial vehicles of various types, with a maximum range of more than 800 kilometers, and there was no problem in conducting reconnaissance patrols within a radius of 400 kilometers of the fleet under the radar guidance of high-altitude airships.

"Drones can only observe the situation on the sea surface, and the terrain below the sea surface is very complex and needs to be detected, which allows us to avoid reefs and dangerous currents, and determine a safe and correct route." A staff officer gave Tianming some common sense about sailing at sea. The importance of the route was reiterated.

Tianming nodded: "Okay then, how many warships should be sent out?" ”

"Let's go out together, run around the fleet anchorage twice, and spend three days to survey the waters within a radius of a hundred nautical miles, and not go far."

"Good! Send a 052D and a 054C out and don't go too far in case of a storm. Be right back! ”

"Yes, Commander!" Li Tianpei stood up and saluted.

"Woo~woo~" After a few whistles, the Yuxin and Huangzhou took anchor and broke away from the fleet group. Conducted his first patrol mission since coming to Blue Mercury.

……

Wu Ke and the others had just settled down, and after a day of excitement, they immediately put their equipment up and continued their ship design work.

The living boat is almost already designed. Based on the drawings they provided, Tianming built a model of the ability of a living ship in the ability space.

The purpose of building a living ship. Not for the earthlings, but for the blue stars.

Although the hoist ship is relatively stable, its speed is too slow and fragile, which is a complete drag on the fleet envisioned by Tianming.

"Boss, the core structure of a gas turbine is actually similar to that of an airplane's turbofan engine, after the fuel is burned in the cylinder, it drives the steam lobe to rotate at high speed, so that the impeller and shaft rotate, and then, through the gear rod device at the end of the shaft, drives the propeller, and finally pushes the ship forward...... If, as you said, it is not particularly difficult to simplify the structure of the steam turbine to a level that can be operated by one or two people, as long as part of the fly-by-wire operating system is removed, and a lighter and a fuel valve adjustment device are left, then it is not impossible for one person to operate. The gas turbine engineer said to Tianming.

Tianming looked at the design drawings on the computer, nodded and said, "The structure is simplified, will the power of the engine decrease?" ”

"Nope! Boss, your ability is too powerful, a lot of parts put together, you only need to form it at one time, the sealing and stability are far stronger than the average gas turbine, according to my estimates, although the structure is simplified to the extreme, but the road is simple, not only will the power not be small, but there will be a large increase! ”

"Oh, that's good."

The engineer's words gave Tianming a lot of confidence, but he also had worries: "Boss, if hydrogen is used as fuel, it may be difficult for the engine to be used for a long time in a high-temperature environment, and the materials cannot withstand such a harsh working environment. ”

Tianming said confidently: "You don't have to worry about this, let me build the steam turbine first." ”

The important weapon of the country, power first. Whether it is a car, a ship or an airplane, the power system is always the first, if the power system problem is not solved first, even if the other problems are solved well, it is only zero.

In the next three days, Tianming built a 16-ton gas turbine with silver steel materials according to the design model given by the gas turbine engineer.

The appearance of the gas turbine is a bit like a horn with a thin middle and thick ends, but inside the horn, there are 8 layers of wheel blades, relying on these blades, 30%-38% of the heat generated during fuel combustion can be absorbed and converted into the working power of the gas turbine.

The test bench of the gas turbine is a temporary test ship cast by Tianming from 8,000 tons of black iron ore - the structure of this ship is like a piece of bread, to be exact, like a sealed coffin floating on the sea, in order to save time, Tianming only took 2 hours to make this "black coffin".

"Activate!"

At the sound of an order, the engineer opened the fuel valve of the hydrogen tank and ignited it! The hydrogen gas burned violently in the cylinder with a loud bang. The wheels and shafts began to rotate, driving the two underwater propellers to rotate at high speed, stirring up a large white splash, and the test boat slowly started and accelerated, and after 5 minutes, the speed reached the limit.

One of the engineers standing at the bow of the ship shouted: "22 knots, the speed of the ship is 22 knots!" ”

Tianming frowned slightly: "Why is the speed so slow?" Can't even get to 30 knots? ”

With a boom, the engineer shouted, "Boss, at a speed of 22 knots." The single power of this gas turbine has reached 38,000KW, which is equivalent to 50,000 horsepower, which is 50% larger than that of ordinary gas turbines, and can run at an ultra-high speed of 45 knots if installed on a 3,000-ton ship! The 10,000-ton warship is equipped with 2 units, and it can also run at a speed of more than 30 knots very easily! This steam turbine is too powerful. ”

"50,000 horsepower?"

Tianming was a little staggering, the Lidong had a steam turbine and eight rocket vents, and the fastest way to run was 38 knots, and it was a fuel-consuming monster.

And this gas turbine. Although the structure is a little more complicated and it took me another 3 days, the effect is very good, only 16 tons. It has played most of the effects that all the power systems of the Lidong can achieve combined.

"I can't stand it, it's hot, it's hot!"

Steering the rudder at the stern and the engineer ran to the bow of the boat, fanned his sweat with his sleeve, and said to Tianming: "Boss." The engine is too hot and I can't stay there. ”

Tianming quickly turned off the fuel valve, and the rumbling stopped abruptly.

After pouring hundreds of tons of seawater to cool the engine. Looking at the remaining fuel in the fuel tank, more than a third of the twenty cubic meters of liquid hydrogen remained. The liquefied hydrogen gas that was consumed burned for half an hour.

"At this rate of fuel consumption, under the condition of extreme speed, it consumes about 800 cubic meters of liquid hydrogen a day, which is equivalent to one-sixtieth of the Lidong......"

Tianming shook his head and smiled bitterly: Science can really improve efficiency.

After solving the most difficult gas turbine problem, Tianming first built 20 gas turbines, and then began to build ships frantically.

The living ship for the Blue Star people is expected to have a displacement of about 5,000 tons, and the overall frame and hull are all silver and steel. Because of the low density, high strength and good toughness of silver steel, when Tianming was building a ship, in addition to the keel being slightly stronger and stronger, the thickness of the hull was only half a centimeter thick, so it was said that it was to build a ship with a displacement of 5,000 tons, but the silver steel used was only more than 2,000 tons.

The internal structure of the living ship is similar to that of the Lidong, with all the facilities: kitchen, warehouse, fresh water cabin, and rest room, but it has also been simplified to a certain extent, such as a bathing room and toilet, and there is only one on each ship, which is very large, and the bathhouse can accommodate 200 people at a time to take a bath at the same time, and there are also 200 squatting places in the toilet.

Because to solve the problem of overheating of the engine, each living ship, the fresh water tank also has a set of cooling devices connected to the power room. The large amount of heat generated during the use of the gas turbine is enough to heat all 1,600 tons of fresh water in the fresh water tank to a high temperature state in three hours.

The most humane point: in order to increase the light transmission of the interior of the living ship, Tianming opened a 2-foot square window in each crew cabin and installed a high-strength transparent glass, so that during the day, the people in the cabin did not continue to light the fish oil lamp - the light shining into the cabin from the glass window, coupled with the reflection of the white silver steel wall, was enough to make the interior of the cabin as bright as day.

A living ship can accommodate 3,000 people, and in the case of high density, it can accommodate 5,000 people, except that the hull is slightly smaller than the Lidong, so to speak, the living conditions are not much worse than the Lidong, and the hoist ship is far better.

Because water pipes, diesel pumps, batteries, generators, searchlights, etc., which are also installed on the ship, must be purchased from outside.

The installation of many internal systems, such as power systems, pumping systems, and ventilation systems, was carried out by 1,000 engineers from the base to assist in the installation. Therefore, Tianming built 8 living boats, a total of 15 days.

In 15 days, all eight living ships with power, ventilation, drainage, small-area power supply, lighting and other systems were built, this speed stunned everyone, the people of Blue Star thought it was a miracle, and the people of the earth felt that this was a demon, a demon-like person, a demon-like shipbuilding speed!

After learning that Tianming's next plan was to build a warship, Liu Haiyang shook his head at the other officers and smiled bitterly: "I began to believe that he has the strength to conquer Blue Mercury, maybe after a while, we will be redundant." ”

"Nope! Instead, I think that we are not redundant, but more important. Li Tianpei's eyes were blazing, and there was a divine way.

"That'...... Just wait and see. ”

……

On the other side, the Blue Star people, who had been living in the hoist boat and several silver and steel boats without power units for more than a month, happily carried large bags and small bags and stepped on the boarding board of the living boat......
