ps: Some readers ask why Mr. Wen is not called the emperor? Here is a little answer, the reason is very simple, don't you think "Mr. Wen" is better than "emperor"?

Also, ask for tickets on the last day......

On September 29, 2758 (1917), Xi'an Aircraft Company.

Xi'an Aircraft Company is one of the 14 most powerful aviation companies in China, and these 14 aviation companies are also nicknamed "14 Flying Taibao".

These aviation companies are carefully planned, and their main projects are planned, and the basic principle is that there are at least two different companies in each category, which is to maintain the vitality of healthy competition.

Among them, Chengdu Aircraft Company (Chengfei), Hubei Aircraft Company (Efei), and Guangzhou Aircraft Company (Guangfei) are mainly fighters and attack aircraft. Xiangyin Aircraft Company (Xiangfei) and Bohai Aviation Equipment Company (Bohang, located in Longkou) are mainly seaplanes. The main products of light transport aircraft, liaison aircraft, training aircraft and special aircraft are Beijing Aviation Equipment Company (Beihang Airlines), Nanchang Aviation Equipment Company (China Southern Airlines) and Shenyang Aircraft Company (Shenfei). Xingke Aircraft Company (Xingfei) and Zhengzhou Aircraft Company (Zhengfei) are mainly large and medium-sized airships. The main products of Xi'an Aircraft Company (Xifei), Jinling Aircraft Company (Jinfei) and Shanghai Aircraft Corporation (Shangfei) are large and medium-sized aircraft such as bombers and transport aircraft.

The only exception is Changhe Aircraft Company (Changfei), which is mainly based on rotorcraft and helicopters, because it is a new product, so it is currently the only one. However, this kind of independent business will not last long, because the Harbin Aircraft Company, which also focuses on helicopters, will start production early next year at the latest.

Of course, there are not only these 14 aviation companies in China, they are only the 14 most powerful state-owned enterprises, in addition to them, there are dozens of private or joint-stock aviation enterprises. Compared with the "14th Flying Taibao", these enterprises are much weaker in terms of productivity and R&D strength, and most of them are light civil aircraft, light airships, gliders, paramotors, balloons and other low-tech complete aircraft, as well as aircraft parts and components subcontracted by the "Flying Taibao".

Among the three enterprises dominated by large and medium-sized bombers and transport aircraft, Xifei is the oldest and the most powerful. The H-2 "Egret" heavy bomber and the H-3 "Warship Bird" torpedo bomber are their masterpieces.

We have to admit that war is the strongest catalyst for science and technology, and after the outbreak of the European war, aviation technology in all countries of the world has been advancing by leaps and bounds. In addition, with the reference of various Chinese products, the aviation technology of the original plane far exceeds the level of the original space-time, at least equivalent to the level of the 20s of the original space-time, and some sub-projects have even reached the level of the 30s.

In such an environment, China, which is considered to be the number one air force, will naturally not relax the development of new technologies, let alone sit back and wait for everyone to catch up. Although China did not participate in the war, its investment in aviation technology was no worse than that of those participating countries. In the past few years, China's aviation enterprises have completed the trial production and test flight of dozens of new models, although there are not many officially finalized products, but also accumulated a lot of valuable experience.

At this time, there are two large aircraft parked at the test airport of Xifei, judging from their shapes, they are the latest models that have not been available before, and they are obviously new product prototypes that have just been completed.

Both aircraft were unprecedentedly large aircraft, and the smaller one on the left was a two-wing, four-engine aircraft. The one on the right is a behemoth, but it's a large plane with six engines on its wings.

Lieutenant General Li Mishi, deputy commander-in-chief of the Air Force, was observing the two planes at zero distance, surrounded by a group of officers and high-ranking officials of the West Flying Force. Li Mishi stood under the plane and tilted his head, looking at the six-engine heavy plane with a happy face. This kind of plane is as tall as a three-story building, and he is 1. 75 meters tall is about the same height as the wheels of an airplane.

"It's really big, I'm afraid this is the largest plane in the world!" Li Mishi patted the large wheel next to him. As a senior aircraft party, Li Mishi really likes airplanes, probably because he has been fighting against Lin Shenhe's "airship control" for a long time, and he prefers large aircraft. For Deputy Commander-in-Chief Leba, the bigger the plane, of course, the better. But an airplane is an airplane after all, and it is impossible to compare the size with an airship. Deputy Commander-in-Chief Cheng Dù Li is already very satisfied, so take your time.

Mr. Li, this is by far the largest aircraft ever built in the world. The Y-3 has an overall length of 30 meters, a wingspan of 55 meters, and an overall height of 9. 8 meters, 25 tons of empty weight, maximum take-off weight of 47 tons, can carry 14 tons of cargo, deservedly the largest aircraft ......," Song, general manager of Xifei, introduced next to him.

"Well, that's good...... Li Mishi looked at the plane again and asked, "I heard that it uses a lot of non-metallic materials, is that so?"

General Manager Song replied: "Yes, Mr. Li." In order to reduce weight and cost, and reduce the use of aluminum alloy, the machine uses a large number of wood, plywood and canvas. Most of its wing structure is made of plywood and cloth skin, the fuselage is made of metal tubes and wooden beams, the outer sides are covered with painted skin, and the interior of the cabin is covered with thick cables to carry the load. Even the earliest designs and even the propellers were wooden, only to be replaced later by three-bladed all-metal variable-pitch propellers. ”

"It's unbelievable! I don't think anyone who sees it can imagine that it's an airplane made mostly of glue, wood and canvas. Li Mishi sighed.

"This is also a miracle in China's chemical industry, if they do not provide qualified plywood and special glue, we have to use aluminum to build aircraft, so that the cost will be at least three to four times......" General Manager Song is very modest, by the way to the chemical mouth of the friends to praise.

Li Mishi nodded: "You are doing the right thing, our military spending is limited, so cost performance is very important." Besides, weapons are consumables, and the army will not need too many weapons that are too expensive. Oh, I've heard that the wood used to make airplanes is very particular......"

"Yes, there are many requirements for the wood used to make the aircraft, and we have tested many types of wood and found that Siberian cedar is the most desirable material, followed by other boreal conifers. Generally speaking, high-latitude timber is the best, and tropical timber is basically not usable...... General Manager Song said with a smile: "At present, most of the timber we use to make aircraft is imported from Russia. Although timber from Canada and the Nordic countries is also good, because of the long distance, the transportation cost cannot be reduced, and it is still not as cost-effective as Russia. ”

"Siberia, I see......" Li Mishi nodded thoughtfully.

This Y-3 large transport aircraft is the latest achievement of Xifei, it looks a bit like the German Messerschmitt ME323 aircraft, but the body is more streamlined, not the bus style of the ME323, because the power is sufficient, and there is no need for liquid take-off and landing booster rockets. It has many design ideas of later transport aircraft, such as a cargo compartment with a large volume and a low floor, an openable nose door and a multi-wheel landing gear, etc.

Its powertrain is six "HHY-05" piston liquid-cooled engines, each with a power of 1,000 kW (1,341 hp). The maximum speed is 300 km, the cruising speed is 230 km, and the ceiling is 6000 meters. With a full load of 14 tons, it is possible to sail 1400 km. If the load is reduced to 8 tons, it can fly 2,000 kilometers. It's definitely top-notch performance in this day and age.

Next, under the leadership of the factory, Li Mishi boarded the plane to visit the cockpit, cargo hold and so on. Representatives of the military are interested in that 11 meters long, 3. 5 meters wide and 3. The 5-meter-high monolithic warehouse is full of praise. Because it was a new plane that had just left the factory, there was a pungent smell of glue in the cabin, but for military people, this smell didn't matter at all.

……………………………………………………………………

Next, they began to visit another four-engine aircraft.

This plane is completely different, the Y-3 just now is a military transport plane, but it is a passenger plane.

When Li Mishi walked on the gangway to board the plane, he asked by the way: "This is the Y-2 Gray Goose transport plane that you improved with bombers......

"Uh, yes...... After the failure of the No. 43 plan, we redesigned it and became a passenger aircraft......" General Manager Song and the representatives of Xifei were a little embarrassed.

Because the origin of this aircraft is not so glorious for Xifei, its predecessor is a bomber used to compete for the successor model of the H-2 last year, codenamed "Plan 43". At that time, Xifei, Jinfei and Shangfei all participated in the selection of new heavy bombers, and all three came up with their own new heavy bomber plans.

Jinfei and Shangfei are new factories, there is no baggage, and they are all very radical all-metal monoplanes. However, Xifei was too conservative at that time, and the "No. 43 plan" that came up with was a two-winged four-engine design.

As a result, it is naturally not difficult to imagine that the "No. 43 plan" of the western flight could not enter the eyes of the Air Force at all, and it was eliminated in the first round of test flights. But this design is not without merit, its flight is very stable, and the safety is surprisingly good. Well, such characteristics are clearly more suitable for being a civilian aircraft.

At the beginning of this year, the Ministry of Communications just came up with this year's "Civil Aviation Development Plan", which requires several civil aircraft, including large passenger aircraft, and the Ministry of Communications has issued a bidding notice to aircraft companies across the country. After receiving the notice, the chief engineer immediately took out the unsuccessful "No. 43 plan", and after some magic changes, it became the current Y-2 "Gray Goose" passenger transport aircraft.

In the bidding for large passenger aircraft of the Ministry of Communications, there are three companies participating in the competition at the same time, in addition to the old rivals Jinfei and Shangfei, even Bohang also came to join in the fun. Of the four models, the "Grey Goose" is the slowest in terms of speed, and it is also an old-fashioned biplane. But we all know that the most important indicator of an airliner is safety, followed by comfort, and speed is really not the most important.

As a result, "Gray Goose" completely overwhelmed the three opponents with its extremely high safety and flight stability, and Xifei finally pulled back a game. According to one of the judges, "Yes, it's slow, as if it's flying against the wind, but it's more about elegance and safety." ”

The Grey Goose is a biplane with an unequal wingspan, and its shape is relatively similar to that of Handley Petti's H in the original time and space Britain. p。 45 airliners. The whole aircraft uses a large number of metal structures, only the rear section of the fuselage and the surface of the wings are covered by fabric skin, the two wings are fixed by more than a dozen crossed struts, the two horizontal stabilizers are equipped with three vertical tails, the rear three-point fixed landing gear is adopted, the power system is four "HHY-05" piston liquid-cooled engines, each with a power of 1000 kilowatts (1341 hp), and the four engines are installed in the engine nacelles located in the upper and lower wings.

The "Grey Goose" has a crew of 6 on board, can carry 40 passengers, has a maximum speed of 260 km, a cruising speed of 210 km, and a range of 1800 km.

"Buzz ......"

Amid the roar of the engines, the two large planes glided one after the other, and took off one after another. They were in the air for an hour before returning to the ground.

The Y-3 "Flamingo" heavy transport aircraft has shown its superior take-off and landing performance, it only needs 400 meters of runway to take off, and it only needs 200 meters of dirt runway to stop when landing, which is very suitable for battlefield conditions.

………………………………………………………………

While Xifei was carrying out the acceptance procedures for the Y-2 and Y-3, the two old rivals, Jinfei and Shangfei, were also carrying out the acceptance work of their new models.

In last year's new bomber competition, Jinfei and Shangfei both won the bid, and Xifei and his family fell off the list. Jin Fei is a H-4 heavy bomber, the world's first all-metal structure four-engine monoplane heavy bomber. This bomber looks like the original space-time B-17, well, it was originally a magic version of the B-17. The H-4 has a bomb load of 5,000 kg, a maximum speed of 430 kilometers and a range of 3,500 kilometers.

The model launched by Shangfei is a twin-engine bomber, although the bomb load is not as good as the H-4, but the other performance is very good, especially the speed, it actually broke through 480 kilometers, which is faster than all the current fighters, so it was also selected as a medium bomber, and was finally named the H-5 medium bomber. The H-5 looks a bit like an enlarged version of the original DH98 Mosquito bomber, but the nose sticks out longer. Unlike the Mosquito, the H-5 is an all-metal structure. The H-5 has a bomb load of 2000 kg, a maximum speed of 480 km, and a range of 2600 km.

Four H-5 medium bombers formed a trapezoidal formation and swept at high speed at an altitude of 8,000 meters, pulling up eight columns of white smoke behind them.

"Hahahaha, it's so fast! It's so fast! The bomber is actually faster than the fighter!" On one of the planes, the military representatives who came to inspect the aircraft were so excited that their faces were flushed.

At this time, the driver suddenly said: "Colonel Nian, in front is Jin Fei's H-4......"

"Oh, it's Lao Liu, they ......" Colonel Nian saw that there were two large four-engine planes flying in front of him at 10 o'clock.

Colonel Nian hurriedly said to the driver: "Hahaha, catch up and overtake them......"

The two groups of planes flew back from the sea after you.

At the Shanghai Passenger Ferry Terminal, a foreign tourist who had just disembarked looked at the planes curiously.

"Is this China's new plane?" the man said in Russian.

At this time, a lieutenant ** officer wearing the uniform of a naval major came over and asked him in Russian: "Excuse me, are you Mr. Kolchak from Nagasaki? I am Major Yu from the reception office of the Chinese Navy, and I have been ordered to come to pick you ......up."
