Traveling through the sword to engage in military industry

During the Fifth Five-Year Plan, the Dawn Research Institute's Communication Technology Research Center at Dongda University once again made significant technological breakthroughs!

Optical fibers with a 1Gb transmission capacity were invented and quickly mass-produced. Paired with Gb optical fiber interface switches and routers, Dongda's original 100Mb cable backbone network faced a severe bottleneck in national network exchanges. Although bandwidth could be increased by adding cables, the construction cost for 1Gb transmission was astonishing, considering the transmission distance and speed of the cables. Therefore, under Ren Zhong's intervention, the construction of the first national network was limited in scale, awaiting the development of the next generation of transmission technology.

Now, with the advent of optical fiber transmission technology, the construction of the national backbone network has suddenly accelerated.

The current technology is essentially reducing the construction cost of the long-distance backbone network by an order of magnitude!

After a year of fervent network construction, Dongda's backbone network jumped from Gb level to over 100Gb. Previously restricted network applications suddenly began to explode, transitioning from simple text transmission, such as the Qiū Qiū application, whose first-generation product only had text chat communication functions.

This was because the network terminal access for each user was basically limited to a low-speed connection level of 64KB.

But after the network upgrade, the bandwidth for each user can now be opened up to about 1Mb, which is equivalent to a nationwide network speed boost. This bandwidth can already transmit compressed images and voice.

As a result, the world's first-generation internet began to evolve from text-based forums and websites into second-generation interactive image-and-text-based new websites. Network applications such as Weibo, BBS, and BLOG began to be introduced simultaneously. Ren Zhong did not rely on his prescience to monopolize these applications.

In his view, the development of these digital applications should flourish in diversity, which is the colorful foundation of this world. Of course, these were limited to enterprises within Dongda. For those outside Dongda, it was better to let the chess pieces lurking in the Qianlong Plan monopolize them.

When the Fifth Five-Year Plan was completed, the first version of the Bright Sword World Free Trade Agreement was signed. The first batch of about seventy leading developing countries signed first, including Dongda. The top fifty countries in the world's economies all participated.

By the end of 1970 in the Bright Sword World, while celebrating New Year's Day in 1971, Dongda announced that the total national GDP, after careful measurement and forecasting, continued to maintain a double-digit growth rate of as much as 13%, leaping from 890 billion US dollars the previous year to become the world's number one, successfully breaking through one trillion US dollars!

The news spread, and a billion Dongda citizens cheered!

Meanwhile, the Rogue Eagle, which was originally the number one in GDP, slightly increased by about 3.5% from the previous year's total of 900 billion US dollars, with a total of 931.5 billion US dollars in 1970. Although it maintained long-term growth, its growth rate was no longer a match for Dongda.

The fact that Dongda surpassed them had already been predicted in major economic journals.

However, when this prediction actually became reality, the entire upper class of North America felt a bit sour.

After all, less than eighty years after becoming the world's number one in industrial output value in 1894, they had now lost the position of the world's number one in Bright Sword World.

Although North America still far exceeds Dongda in terms of per capita GDP, with the Rogue Eagle currently having just over 300 million people and a per capita GDP of over 3,000 US dollars, while Dongda only has a per capita of 1,000 US dollars, which is three times less.

However, this could not stop North America from reflecting.

After careful analysis, they almost unanimously believed that the most important reason was that they had fallen behind in terms of technological development!

In the most important IT industry, North America is basically lagging behind Dongda by three generations or more!

After so many years of development, by 1970, Dongda's computer chips had developed to 686, while they had just broken through the mass production of 386. Because the most important lithography machine for chip manufacturing, Dongda's most advanced lithography machine, is kept secret and there is no intention to launch it on the market for sale.

In fact, no one in the world knows what level Dongda's most advanced lithography machine has reached.

They only know that it must be far ahead of the world.

Under the joint research and development of the two major North American semiconductor leaders, MBI and Bell, North America's lithography machine has barely broken through to the 1-micron level. After reaching this lithography processing level, the top chip technology research experts at Bell and MBI felt that the road ahead was coming to an end and that they needed to take a new path.

According to the results of theoretical research, at 1 micron, the light source for lithography needs to be replaced, otherwise the new lithography wavelength cannot support further development.

However, MBI and Bell's experts, who have no reference ideas for the new lithography machine, have to invest money to explore various technological paths.

Dongda, which strictly guards against the leakage of lithography machines and hardly reveals any technical ideas, has never thought of making money by selling advanced lithography machines. They will only consider selling lithography machines that their opponents have already mastered, occupying the market with a price that is about a quarter lower than their opponents.

In this way, competitors have little possibility of making money by selling their own lithography machines, except for obtaining benefits from the chip production process to support the development of the next generation of lithography machines.

It can be said that in the Bright Sword World, the Rogue Eagle has suffered enough from Dongda's technological leadership.

As for Europe, they had already given up on semiconductors.

In the fields of machinery, communication, aviation, and railways, they continue to follow Dongda's pursuit. With a group of lurking companies in the Qianlong Plan and several leading companies having the opportunity to jointly develop with Dongda, Europe's technological development seems to be vibrant on the surface and is no worse than North America.

Especially in the field of aero engines, after cooperating with Dongda to produce the RB211 three-spool engine, they entered the world's top new high-bypass turbofan aero engine industry, which not only solved the power needs of new airliners.

In John Bull's research on the new Tornado fighter, the improved new generation of three-spool engine, the RB199, was modified from the technology and inspiration obtained from the RB211 research.

Compared to their original ten years of development, using 67 experimental engines to successfully develop through massive trials, Rolls-Royce in the Bright Sword World is much easier. Ren Zhong copied the homework and avoided all the big pitfalls of the RB211. Similarly, Rolls-Royce's RB199 also took many fewer detours, and developed the RB199 medium-thrust engine within two years after the success of the RB211.

RB199-104 performance indicators: length 3.6 meters; diameter 0.72 meters; dry weight 976 kg; thrust 40 kN (afterburning thrust 73 kN). Although it is much worse than Dongda's WS9 maximum thrust, the thrust-to-weight ratio is much higher, exceeding the level of 7.

In this way, the research on the Tornado fighter in the Bright Sword World has been greatly advanced.

Relatively speaking, aside from the avionics, in other aspects, this is a fighter jet with performance quite close to the J-9. It's just that it came out ten years later than the J-9. Now, the J-9 has undergone its second improvement and become the J-9C. The biggest change is that the WS-9 engine has been modified again to become the WS-9C, with greater thrust and better fuel economy, bringing stronger maneuverability and longer range.

However, the J-9C is not the best fighter jet in Dongda anymore. Now, the best fighter jet in Dongda is the J-12, which is basically researching the next-generation heavy fighter jet according to the F-15, directly plucking the giant North American company, McDonnell Douglas, bald!

From the F-4 to the F-15, the path that McDonnell Douglas has taken is, of course, equally smooth for Dongda.

However, in the case of the single-engine light fighter J-13, this time, due to the limitations of the aero-engine, it was impossible to replicate the F-16, a divine machine. Ren Zhong chose the JAS-39 "Gripen" fighter, which is relatively more like the J-10 divine machine, for the WS-9C aero-engine to replicate. It has a length of 14.1 meters, a wingspan of 8.4 meters, a height of 4.5 meters, an empty weight of 6.8 tons, and a maximum take-off weight of 14 tons. The key is that its power is a medium thrust, and the RM12 engine can provide the "Gripen" with 54 kN of thrust. If the afterburner is turned on, the afterburner thrust can be increased to 80 kN.

These indicators are completely trivial for the WS-9C. Now, the WS-9C has a thrust of 75 kN, and the afterburner thrust can reach 115 kN! It is similar to the early version of the J-10 in terms of power, but unfortunately, the available data for the J-10 is not as much as that for the Gripen fighter. In this regard, Ren Zhong simply used the mid-term improved model of the Gripen fighter as a blueprint for development. This fighter has a similar technical route to the J-10, both being canard layouts.

Most importantly, the J-12 and J-13 fighters are designed according to the fourth-generation fighter specifications! The introduction of fly-by-wire flight control and static instability design concepts completely subverts the past aerodynamic design methods and flight control mechanisms. A large number of sensors and new aero-engines with a thrust-to-weight ratio greater than 7 are used, and the avionics are fully digitalized.

In the J-12 and J-13, a large number of ARM11 chips and 586 chips are used as the source of computing power. In terms of transmission, Ethernet network transmission is fully implemented, which greatly enhances the sensing capabilities of the fighter jets.

Coupled with the PD second-generation radar system PD-120, and the standard data link LINK-100, the new generation of fighter's collaborative combat capabilities far exceed the previous generation. Now, combat collaboration is not just about relying on direct calls to make pilots cooperate tacitly.

However, after the two aircraft combine to form a combat partner, the fighter's field of vision suddenly expands to the shared field of vision of the two aircraft, using two sets of radar systems to double-locate enemy targets -- the accuracy of this positioning is more accurate than that of single positioning. For guiding missile attacks to hit targets, the success rate of one attack should be increased by at least 10%.

The newest novels are first published on 69shu.com!

Because when the target is locked by two radars, the combat partner guidance will guide the two fighter jets to automatically bite the target aircraft for tracking and attack!

After the computing power that has expanded in the past five years, the new ARM1176JZ-S chip has the characteristics of low power consumption and high performance, and has been widely used in embedded avionics equipment. It is the core of airborne data calculation. As for the two 586 mainframes, they form the main and backup systems, controlling the cockpit data display and map display functions, and guiding the fighter pilots to launch attacks.

When these two fighter jets achieved preliminary mass production and small-scale equipment, they fought against the early second-generation fighter J5A and achieved ultra-high scores of 10 to 0 and 20 to 0 cleanly!

Even against the J-9 fighter, the new J-12 and J-13 also maintain an overwhelming advantage. Single-aircraft combat can guarantee 1VS3 or more, and dual-aircraft combat can easily reach 2VS10. The data sharing and combat sharing functions are much stronger than the pure manual combat mode.

Because human vision and reaction ability are far less far-reaching and real-time than airborne radar.

More importantly, the built-in combat escape system will automatically prompt its own safe range according to the opponent, how many kilometers of distance need to be maintained to be relatively safe when facing what kind of opponent, and at the same time, it can form a fatal attack on the opponent.

Technically speaking, this principle is not difficult. As long as the radar can accurately judge the opponent's fighter model through radar signals, it can deduce the opponent's air combat weapon types, the maximum effective range of these weapons, and the escapable area range of the J-12/J-13 in the face of these weapons.

In this way, the pilots driving the J-12/J-13 can ensure their safety according to this prompt range.

Such black technology, according to the general situation, should not appear in this era at all, but for Ren Zhong, this is just a small-scale application of artificial intelligence in the main world.

As long as the radar measurement of the opponent's target is accurate enough, then from a computer logic point of view, there is no major threshold.

With these two new big killers, Ren Zhong felt that the sky would no longer fall.

The J-12 can be an air superiority and multi-functional heavy fighter to protect the homeland, while the J-13 can realize more combat fields, and will be transformed into a carrier-based aircraft to undertake the heavy responsibility of the next generation of carrier-based air superiority fighters. As for ground attacks, they will continue to be handed over to the new generation of Qiang-9C attack aircraft after the engine is replaced. As an enhanced Qiang-9C with enhanced power and strengthened new protective armor, the battlefield survival ability has been greatly improved. All core parts have the ability to prevent the scattering of heavy machine guns, which is safer for performing front-line bombing missions.

If there are any shortcomings, it is that the cost of these two fighter jets is much more expensive than the previous generation.

Even the J-13 light fighter is more expensive than the old generation fighter J-9, and the J-12 heavy fighter is directly twice as expensive as the J-9.

The application of new sensing systems, new materials, and new radars are all places where a lot of money is spent, which greatly increases the cost of the new generation of fighter jets.

In view of this, the timing for these two big killers to replace the previous generation of fighter jets on a large scale is not very mature. Instead, according to the plan, one aviation regiment is replaced by one aviation regiment.

Now, the production line that has exploded by building civilian aircraft with an annual output of hundreds of airliners will quickly be transformed into a fighter jet production line during a real war, so after the research is completed, it is more in the form of demonstration aviation regiments to equip them, so that the air force can familiarize themselves with these two fighter jets and can conduct a considerable number of pilot training.

Make preparations for the large-scale equipment of new big killers in the future.
