PS: I miscalculated in the previous chapter, the "Penglai-class" frigate, when fully charged, can run at a cruising speed of 20 knots for thirty hours, a whole day and a night, or three and a half hours at a top speed of 37 knots.

........................................................................

On January 11, 2765 (1924), Chengfei was born.

On the "Little Singles' Day" in 1923, Wen Desi came to the Chengdu Aircraft Company to inspect the development of new aircraft. At this time, he was visiting a new aircraft, accompanied by Chengfei's senior management.

This is an airplane with an earthy yellow paint, and Wen Desi remembers that in the original time and space of the Datu Dynasty, the paint of the weapon was known for being ugly and ugly, and it was often spit out by the military fans as full of dirt and turtle, thinking that it was better to outsource the paint design to an advertising company. Military fans unanimously agree that "the paint design of the big picture" and the "appearance design of the British" are the two ugliest things in the world, and the two go hand in hand, in no particular order.

Because in addition to fighting, weapons also have a very important function, which is used to display B. Weapons with beautiful appearance, outstanding appearance, and gorgeous paint are very compelling, which is very helpful to the morale of the people, and even has a positive impact on the morale of officers and soldiers. Just like the British Nelson-class battleship, in good conscience, its performance is quite good, but because the shape is too ugly and the appearance is too low, many officers and men of the Royal Navy would rather serve on the old warships than on the Nelson-class. They claimed: to serve in the Nelson class is like driving a cargo ship, and there is no feeling of driving a battleship at all.

In fact, China's weapons are not as big as opium cows because their brains are not as big as opium cows, so their appearance and appearance are not too bad, but the painting is too frustrating, and this is the easiest to change. Therefore, China in this plane is very concerned about the painting, and all the weapon painting is designed by professional artists.

The color of earthy yellow is very compelling, and as long as you put earthy yellow on any weapon, it feels immediately taller. However, the most compelling is the gray-black paint, some people have used several aircraft of the Tu Dynasty to PS, under the kind of sassy paint, even the oldest strong five suddenly have the "Great East Asia decisive battle weapon" fan.

The aircraft was a single-engine fighter with engines housed in the fuselage immediately behind the pilot. The air intakes are located in the fuselage, immediately at the front end of the wing root, and exhaust gases are exhausted from the very rear of the fuselage. Fitted to the side of the fuselage there are air deflectors that prevent air from separating inside the air intakes. There is also a "dive-recovery" aileron on the lower surface of the leading edge of the wing, and the split trailing edge of the wing is used to provide lift at low speeds.

The aircraft looks somewhat similar to an earlier model of the original F-80 fighter jet, with a line written underneath its cockpit: "1022 Project Verification Aircraft No. 5". That's right, this is the No. 5 machine, and the first few planes were used for static experiments, body strength experiments and other experiments.

“...... Its cockpit is pressurized and air-conditioned, and it is also equipped with ejection seats. Mr. Wen, we are now using the fourth-generation iron dragon battery, oh, it should be called the copper dragon battery now......" Liu Xingyuan, general manager of Chengfei, introduced to Wen Desi next to him: "Since the copper dragon battery, the technical problems of the microwave combustion system have now been solved, and the progress of our new aviation engine has been accelerated a lot." With the microwave combustion system, the power of the new aviation engine can be increased by 15%, and the fuel consumption can be reduced by 20%......"

Now China's high-energy batteries have developed to the fourth generation, and the performance of all aspects has increased significantly, and the highest first-class product is an energy density of 3000 watt-hours/kg, a power density of 6 kilowatts/kg, 3500 times of charge and discharge, and a production ratio of 35%. The second-class intermediate grade is an energy density of 2400 Wh/kg, a power density of 4 kW/kg, 2800 times of charge and discharge, and a production ratio of 45%. The low-grade third-class products are energy density of 1800 watt-hours/kg, power density of 3 kW/kg, 2000 times of charge and discharge, and 20% of the output.

So Mr. Wen waved his pen and named it the copper dragon battery.

"What kind of hair does it use?" asked Wen Dehei.

"It is a WP-Z-02 axial turbojet engine with a thrust of 2,000 kilograms and a service life of 300 hours......," Liu Xingyuan replied.

Incidentally, most of the engines studied in China's turbojet engine program are axial-flow, and radial (centrifugal) engines have not been the focus from the beginning, but only as a technical reserve. Although the latter is relatively simple and easy to implement, since the former is the mainstream, and now that World War I has just been fought, it is impossible for a large-scale war to occur in a short period of time.

"What about weapon systems?"

"2 x 20 mm guns and 4 x 12 mm machine guns ......"

Wen Deji circled around the plane and said to everyone: "So, now it's time to start the first flight......

"Mr. Wen, we have done a pre-flight inspection and can ......take off at any time."

........................................................................

When they walked into the control tower, the test pilot also sat in the cockpit. Ten minutes later, the engine of the No. 5 engine started, it slowly accelerated on the runway, the tail jet spewed orange-red flames, the plane got faster and faster, when it slid to a distance of about 600 meters, the speed had reached 300 kilometers, at this time it spread its aileron and flaps, and as soon as the nose was warped, it roared into the sky.

On another runway, an accompanying piston plane also took off.

"This piston plane is the Type 1011 fighter you're working on now, right?" asked Wen Desi.

"Yes, Mr. Wen. This is a Type 1011 fighter, which has been tested several times and has been very successful. The engine power is 1,800 kilowatts, and the maximum speed reaches more than 680 kilometers per hour...... Liu Xingyuan explained with a smile: "However, we don't count what we said, and we have to go through the army's acceptance." Its competitors are new fighters from the Efei and Guangfei. ”

Jet planes are still in the verification stage, and even if the test flight is successful, it will have to wait at least several years for the troops to be formally equipped, after all, there is no war pressure now, and with the consistent style of the CSS, there will be no large-scale equipment without a mature model. So during this period, piston fighters are also needed for the transition.

At present, China's piston engines, whether liquid-cooled or air-cooled, reach more than 1,800 kilowatts (2,413 horsepower). Moreover, China's current aircraft design has learned "historical lessons", and it is all about the engine as the core of aircraft design, rather than the reverse way around, first design the aircraft, and then design the engine. This saves a lot of hassle, increases the versatility of the engine, and reduces logistical pressure. So now although there are many types of aircraft in China, there are only a few kinds of engines.

"It's like a big baby bottle with wings...... Wen Deji looked at the round, chubby Type 1011 fighter jet, and couldn't help but think of the baby bottle that his children used when they were young, and couldn't help but smile and say.

Liu Xingyuan's face turned red, and he hurriedly explained: "Mr. Wen, although it looks like five big and three thick, it is very bulky. However, due to its new air-cooled engine and special turbocharging system, engine water injection and other technologies, it not only has strong firepower, but also high-altitude maneuverability and dive performance are more prominent. On top of that, its fuselage is sturdy, with armor protection for the cockpit, engines, and fuel tanks, making it extremely survivable. We did destructive tests, and after dozens of 12mm machine gun bullets, even if one of the wings was knocked off, it could still return safely, which is something that no fighter in service can do......"

Mr. Liu couldn't help but sweat, now the three airlines of Chengfei, Efei and Guangfei are competing for the next main fighter, which is to use their strength to eat, and the competition is very fierce. Because the three are using the same level of engine, and the design level of everyone is about the same, the performance of the two aircraft of Efei and Guangfei is not bad at all. Although Wen Deji generally does not interfere in the selection of weapons in the army, if he says something, it is impossible for the army not to listen.

Fortunately, Wen Deji just smiled now and didn't continue to say "Bottle Fighter".

At this time, the experimental jet, accompanied by the "big bottle", circled the airfield several times, and then it began to accelerate towards the north.

At first, the "big bottle" could still follow behind, but ten minutes later, it was left far behind by the jet and eaten in ashes. Even if it turns up to its maximum speed, it's out of reach.

Speed radar quickly measured its speed. "The maximum speed is 950 kilometers per hour...... in fact, the speed of the "big bottle" that looks stupid and cute is not slow at all, and the maximum speed has reached 690 kilometers per hour, which is already very powerful in a piston aircraft. But unfortunately it is compared, compared with the jet next to it, it is not good at this speed.

Half an hour later, the two planes landed one after another, and before the planes could stop steadily, enthusiastic cheers rang out from inside the airport.

At the summary meeting afterwards, Wen Desi said: "This aircraft is still very good, but the life of the engine is still a little shorter, if it is a wartime, this life is acceptable, but if it is peacetime, 300 hours is a bit low." ”

In the case of rapid attrition in wartime, the fighter will be lost after a long time, and the average life is very short, for example, in the original time and space of World War II, at the most intense time, not to mention less than 300 hours, the average life of the fighter will not even exceed 100 hours, so the engine and airframe life can be allowed to be lowered to reduce costs. However, in normal times, such an aircraft with frequent engine changes would be too expensive to operate, not to mention that jet engines are much more expensive than piston engines.

The leader of the engine company next to him was anxious, and hurriedly said: "Mr. Wen, this engine is just a test model, the next generation of jet engines we are developing will use single crystal blades, and the service life can definitely reach more than 1000 hours......"

........................................................................

After the inspection was completed, Wen Desi boarded his special airship for the head of state and flew to Xinjiang to inspect the progress of those key black technologies. On the way, there was a squadron of fighter escorts, and two other airships were accompanying them.

As the number one air force power, the airship dedicated to General Wen is naturally a luxury helium airship at the level of the "Air Palace", but the Air Palace is a 200-ton giant airship, which is mainly used to show off abroad, because it is too big, and it is not a special airship field that cannot be stopped at all. So in China, he mainly uses a smaller airship, which is small, but it is also relatively speaking, this is also a 40-ton large airship.

This airship is a new type of soft airship that will not have the problem of structural damage caused by storms. This airship is also luxuriously decorated and functional, and is spacious, smooth and quiet, and it is completely different from an airplane. Although the carrying capacity is only 40 tons, there is no problem with the luxury airship used for VIP rides, and the safety is much higher than that of an airplane. In fact, it is precisely because of its stability, quietness and safety that Mr. Wen generally takes this airship and rarely takes planes.

Now their purpose is near Lop Nur in Xinjiang. That's right, the nuclear physics research base of the republic.

That night, they successfully reached the base of Lop Nur. China currently has two major nuclear research bases, the earliest being Helan Mountain, built in 1911, and then the current Lop Nur base, which was built in 1918. The main tasks of the Helan Mountain base are nuclear power plants and the extraction of nuclear materials, as well as basic research in nuclear physics. The main task of the Lop Nur base is all kinds of nuclear weapons.

Thanks to the many materials available in later generations, the objectives of China's nuclear program are very clear, and the ways and main ways have been determined. The various technology trees and roadmaps are also very scientific and reasonable, and they are all optimized routes, without any detours. After 13 years of rapid development, China has made great breakthroughs in nuclear technology.

First of all, nuclear power plants, the use of nuclear energy is the main purpose of China's nuclear program, and nuclear weapons are only by-products of it, which is also completely different from those nuclear programs in the original time and space. China's nuclear power plants skip the first and second generation reactors of the original time and space, and go directly to the third generation. However, even the third-generation reactor is only experimental in the eyes of Mr. Wen, and it still cannot be used for commercial operation.

After several years of development, China's nuclear reactors have developed to the fourth generation, and now China has built six fourth-generation reactors, which are used for six types of reactor research. At present, the most desirable performance is the gas-cooled fast breeder reactor, which is located at the Lop Nur site.

Thanks to the "enthusiastic assistance" of many "volunteers" over the years, the safety of China's nuclear reactors is very perfect, and accidents aside, at least there is no problem of radiation contamination to personnel during normal operations.

In the central control room of the nuclear power plant, a scientist said to Wen Desi: "Mr. Wen, this is our gas-cooled fast breeder reactor, which is unique in the world. ”

This scientist's name is Li Tianye, who has just turned 30 this year, and is a genius nuclear physicist who stands out among the indigenous scientists of this plane. He has no study abroad experience, and is a "pure suvenir" who graduated from Southwest University of Technology. Li Tianye, who is extremely talented in nuclear physics, is now an important figure in the nuclear physics project, and is currently the chief engineer of the nuclear power plant.
