Only when you are with Liang Yuan, the twins are truly innocent and romantic. Listening to Fu Hengyu's memories and thoughts sweetly, Ning Wanfei said with a naive look on her face: "Let's go back and ask grandpa, do you still remember what Uncle Fu asked to join the army back then?"

Listening to Ning Wanfei's extremely cooperative answer, Liang Yuan held back his smile and straightened out the reasons for the matter. Fu Hengyu took the initiative to lean over. Eighty-most related to Ning Lei's victory in Nansha. As long as he is not a fool, he can basically see that the commander of the Republic's Air Force will most likely fall on Ning Lei's head in a few years. In the age of Ning Lei is only forty years, he is definitely the most shining diamond fifth in the Republic's military.

As someone around 286, Fu Hengyu must know that 286 has the intention to retreat. Whether it is for the cooperation and alliance in the post-286 era or for the next generation of his family, it is beneficial to Fu Hengyu without any harm to the relationship between Ning Jianzhong.

This passage has been revealed, Minister Fu did not communicate with someone with a billionaire, and directly raised the topic on the Northeast Locomotive Factory and Liang Haiping. Instead, someone who was ignored was considered in bad water. Will the twins not be the messenger and throw Minister Fu's charming eyes into outer space?

"Haiping, your resignation request department will never agree." Fu Hengyu said seriously and Liang Haiping.

"Minister, I have promised the Civil Aviation Import and Export Company to be the head of COMAC. I really don't have the energy to take care of the car factory." Liang Haiping said with a wry smile.

Liang Haiping's idea of ​​resigning had already been in contact with Liu Changhe as early as last year. Common sense is that Liang Haiping's resignation railway system should welcome him. After all, another good pit has been released, as long as the successor is not too low in IQ. With the foundation of the Northeast Locomotive Factory, it is very easy to achieve political achievements.

However, after the Long March 3 broke through 200 kilometers per hour, things changed a lot. Since Fu Hengyu saw the hope of completing the "morning and evening" direct express train during the July 5th period, how could he allow Liang Haiping, who was in a critical position, to leave the Northeast Locomotive Factory.

Although the Ministry of Railways, which absorbed the 243 type electric head technology, has already achieved smooth operation speed at the 160-kilometer level. However, in terms of time, no matter whether it is Zhuzhou Factory, Dalian Factory or Qishuyan Factory, it is impossible to use the 200-kilometer level traction head for the department to choose.

Without Liang Haiping in the middle, God knows that the core of power will be responsible for providing the power to which year and month will FAW have to improve the Long March 3? For Fu Hengyu's personal career, this experience in the Ministry of Railways has an extremely close causal relationship with whether he can enter a higher leadership position in the future.

If the Republic Railway can be used as a threshold for high-speed railways during the 75th period, the hope of going from Fu Hengyu to becoming a ministerial-level cadre in the 85th period will increase greatly. From an alternate political-political-business member to a political-business member, it can be said that it is a leaps in the career of officialdom.

Fu Hengyu knew the background of the civil aviation import and export company that had just emerged in the Republic. This was a large enterprise jointly funded by the Hai, Air Force and AVIC. Liang Haiping could be here to serve as the boss. If he had nothing to do with the Lao Ning family, he would not believe it.

"Reform is to liberate the mind and break the frame. Since Haiping agreed to COMAC, I cannot let Haiping be a trustless person. In this way, the Northeast Locomotive Factory can imitate the Guangzhou-Shenzhen Railway Company and transform it into a joint-stock enterprise. Haiping serves as the chairman of the Northeast Locomotive Factory and takes the helm of the company. Daily management can be completed by the general manager." Fu Hengyu proposed a compromise solution.

Having said this, Liang Haiping seemed pretentious to continue to shirk his words. In desperation, Liang Haiping could only nod and said, "I thanked the minister for his wrong love. Although I have limited personal abilities, I have to try my best to continue carrying this burden."

"The more capable ones work, the more they get. Haiping should not be too humble." Looking at Liang Haiping nodding and agreeing, Fu Hengyu said with a smile.

With Liu Changhe's skill, he naturally understood Fu Hengyu's true plan to try his best to keep Liang Haiping. Seeing that Liang Haiping agreed to serve as the chairman of the Northeast Locomotive Factory, Liu Changhe interrupted: "Haiping has caused me a lot. Last month, your car factory said that the Long March could run 160, but today it even broke through 200, which made me criticized by the minister."

Liang Haiping knew it very well. In the case of the Long March 3-breaking 200, it was probably because his elder brother who added the roster made the name of the story, but he could not reveal the truth, so he had to learn from Liu Changhe and put everything on the point of being cautious.

The people in the official railcars talked around the Long March 3 for a long time before Liu Changhe asked tentatively: "Only our country is developing gas turbine motorcycles at present, and there is no international reference example. Haiping believes that there is a possibility that the Long March 3 will be launched now."

"There are three main problems facing gas turbine locomotives now, high-temperature exhaust, fuel consumption, maintenance, and complex maintenance." Liang Haiping said concisely.

"High temperature exhaust gas is not a problem. When the Ministry developed the Long March 1 and the Second, it wrote relevant management regulations. As long as the management is in place, it is not a big flaw." Liu Changhe said.

"As for fuel consumption, if I remember correctly, the fuel consumption during the Long March 3 test run some time ago was basically more than twice that of the Dongfeng 4B nose. If the operating speed of the Long March 3 traction standard group can be higher than 120 km/h, this fuel consumption rate is acceptable for the department."

"The department can't solve the problem of maintenance and maintenance." Liu Changhe finally smiled bitterly.

The Ministry of Railways has focused on the research and development of the Long March 1 and No. 2 gas turbine locomotives for more than 20 years, and has burned two prototypes. Before Liang Yuan introduced the Gem Turboshaft engine, he was completely helpless against the turbine power core.

"How long does it take for Mr. Li to maintainability and reliability of gem power packs to meet the standards for online operation?" Liu Changhe turned his head and asked Li Yuanling.

Since Liang Yuan emphasized the modularity of the power system, Brilliance simply named the power core of the entire turboshaft engine and generator as a power pack, and provided the power packs for Northeast Locomotive Factory to use are all finished sets of packing at the Changbai Island factory, and reserved oil inlet and power output interface.

Li Yuanling lowered her head and pondered for a moment before speaking: "Director Liu, if the Ministry wants to make Long March 3 reach a useful level in a short period of time, there is only one way to go, which is to implement power reduction training for the gem power pack and limit the overload work of the power pack. Taking Long March 3 as an example, if the output power of the gem power pack is reduced by 10%, the reliability and maintenance-free time will increase significantly."

"The problem is that after limiting the output power and overload of the gem power pack, if you want to achieve the traction speed satisfactory in the department, you can only use the dual-machine reconnection to pull, which will increase a lot. Whether the Long March 3 can be quickly entered service still needs to weigh the pros and cons of the department." Li Yuanling finally concluded.

Generally speaking, reducing the pre-vortex temperature of turbine engines can significantly improve the service life and maintenance-free time of turbine. Of course, the side effect is the decrease in the turbine output power.

After hearing Li Yuanling talk about the situation, Liu Changhe remained silent. Although the Road Bureau had the right to place purchase orders alone, it was better to wait for Fu Hengyu to make a statement at this time. It is not the right way to be an official.

Currently, the nominal power of Long March 3 is 822KW×4. According to Li Yuanling's new statement, the nominal power of Long March 3 will drop to 2959KW. The original burst output power of up to 4300KW cannot be used. Maybe another small-power diesel generator set will have to provide cooling, lighting and other conventional power supply for the head.

This means that the three Long Marches are one-third higher than the Dongfeng 4B locomotive commonly used in the Republic, and they are definitely not up to the technical requirements stipulated by the Ministry of Railways when traction is single.

If the power of the Long March 3 is used for dual-machine reconnection traction, it is enough. However, the cost problem is becoming more and more prominent.

Fu Hengyu thought for a while and asked Liang Haiping: "Haiping, if the Ministry provides key support to the Northeast Locomotive Factory, how much is the Long March 3 quotation that uses the dual-machine reconnection method to leave the factory? How much is the reliability and maintenance performance?"

In addition to four turboshaft engines, the higher cost includes a "interchange-direct" rheological frequency conversion rectification system, four high-speed alternator, an electronically controlled fuel pump, and a power pack simulation control system. The rest are low-cost items such as boxes and fasteners.

Liang Haiping calculated that since the domestic production work had just been rolled out, the factory price of four gem turboshaft engines assembled by FAW was around US$270,000, and the four were 1.08 million. The domestic products of high-speed alternators were not stable. At present, FAW chose the French Lileesenma high-speed alternator. It costs 30,000 US dollars to import one of these items, which just threw the cost saved by FAW's domestic production gems.

"Interchange-direct" rheological frequency conversion rectifier system, electronic fuel pump, and analog control system either come from the technical accumulation of the Spey project or from the chip laboratory. However, the three are relatively cheap, which is about 20,000 US dollars. In addition, the heat dissipation fans, boxes, pipelines and other miscellaneous things, the factory price of a gem power pack is around 1.25 million US dollars.

Although the price of the gem power pack is not low, for the Northeast locomotive factory, the workload of developing a new locomotive around the gem power pack is greatly reduced. Just install the driving motor of the head. Make a reasonable body structure and the locomotive's human-machine control system. This part of the budget is 600,000 or 700,000 US dollars to spend.

It's still a bit expensive. Liang Haiping subconsciously smacked his lips. The Republic imported a batch of internal combustion locomotives code-named ND5 from the United States three years ago. The price of a single unit is only US$980,000. The factory price of the Long March 3 is about US$1.9 million. If you choose to reconnect the two-machine, it will cost 3.8 million US dollars. Based on the current exchange rate, the factory price of the Long March 3 is as high as 14 million RMB.

Of course, the traction speed of the Long March 3 is not comparable to that of the ND5. The maximum speed of the General Motors ND5 internal combustion locomotive is only 118 km/h and has limited improvement potential, and it is not a match at the same level as the subsequent model, which is expected to exceed 200 km/h.

Liang Haiping thought about the quotation of a typical high-speed railway traction machine head - the German Railway 120 high-speed electric locomotive. It costs more than 20 million yuan based on the current exchange rate. Although the performance of the Long March 3 is a bit poor, the price has also dropped a lot. This competitiveness is really measured by the Ministry of Railways itself.

"Minister, the factory price of the Long March 3 gas turbine motorcycle reconnected by the two-machine is about 14 million yuan per vehicle." Liang Haiping said word by word.

"After reducing the power, the overhaul interval of the Gem Power Pack can be increased from 4,000 hours to 8,000 hours. The reliability will definitely be better than the Dongfeng series internal combustion engine, and the engine breakage rate should be lower than the general-purpose ND5 internal combustion engine introduced three years ago." Li Yuanling added.

The 8,000-hour overhaul interval, even at a lower operating speed of 120 kilometers per hour, means that the overhaul will be carried out after 960,000 kilometers of the Long March 3 run, and it is slightly stronger than the overhaul requirement of the 700,000-900,000-mile range of Dongfeng 4B internal combustion locomotive.

As for the engine breakage rate lower than that of the general ND5 model, it is due to the working environment of the Gem Stone Turboshaft engine, which is without any dependence on the sky, the engine's safety factor must be higher than that of the diesel unit mixed on the ground.

"Haiping, how fast can the operation speed of the Long March 3 type after the technical transformation? What is the maximum speed?" Fu Hengyu asked immediately.

Liang Haiping roughly calculated the traction power and said: "Theoretically, the Long March 3 gas turbine locomotive reconnected with dual-machine can tow the standard 25S marshalling to reach an operating speed of more than 130 kilometers, and can reach a maximum of 170 kilometers per hour on straight roads."

The Dongfeng 11G internal combustion locomotive in later Republics had a single-machine power of 3040KW. The standard marshal can be traction with a standard marshal to reach a maximum speed of 170 km/h. Although the weight of the double-layer 25S marshal is greater than the single-layer 25T traction by Dongfeng 11G, the 25S marshal uses a self-powered carriage. The head is not used to be responsible for powering the entire marshal. In general, the data distributed in power by the Long March 3 and Dongfeng 11G are roughly similar.

For Liang Yuan, he decided to use four gem turboshaft engines as the power core of the Long March 3 model. A considerable factor was to refer to the Dongfeng 11G internal combustion locomotives in later generations of the Republic. It is normal for the two to operate the same speed.

Bang!

Fu Hengyu tapped the handrail of the sofa and asked with a quick speech: "How long will it take for the Northeast Locomotive Factory to complete the technical transformation of the Long March 3 type? What is the output?"

When Liang Haiping heard Fu Hengyu mention the output, he knew that there was a way to join the Long March 3. He smiled and said, "How many units are planned to purchase in the Ministry? If the car manufacturer dares to invest if it is a large purchase, the cost and output will definitely not be a problem at that time."

Fu Hengyu laughed and said, "The Ministry has a direct express train development plan that arrives day and night. As long as the Long March three modifications can meet the technical standards mentioned by Haiping, the Ministry is planning to open direct express trains from Peiping to Wusong, Nanjing, Changsha, Wuhan, Hefei, Shengjing, Changchun and other places at one time, and the purchase volume of the first batch alone will not be less than 100 vehicles."

Liang Yuan almost burst out when he heard this. Fu Hengyu was basically planning to bring the Republic Railway in later generations, the most famous "pig herd" before the high-speed railway was opened.

After entering the new century, the direct express train led by Dongfeng 11G has a reputation among the people of the Republic even higher than the CRH high-speed railway, which has become the business card of the Republic's railway.

Since the appearance of Dongfeng 11G is similar to a pig's head, and the direct express train that it is responsible for traction is abbreviated as ZT, the direct express marshalling is widely called "pig herd" inside the railway and among the people.

The reason why the pigs were still obsessed with by the people during the high-speed rail era is due to their reasonable prices and operating time. Take the benchmark line of the Republic, Beijing-Shanghai Railway, as an example. The entire operation time from Wusong to Beiping Zhite is 11 hours and 58 minutes, the soft seat ticket price is 283 yuan, the soft bedding is only 499 yuan, and the train departs from 6:00 to 7:00 in the evening, and arrives at the destination between 6:00 and 7:00 the next day. It is equivalent to staying in a hotel for one night.

In the peak of the glorious pig herd in 2007, just to meet the daily passenger flow in Beijing and Shanghai, Beijing and Shanghai stations had to use a seven-minute tracking departure method between 6:00 and 7:00 pm, and five to eight consecutive marshallings were sent to meet the strong demand. At that time, watching seven or eight groups of pig herds on the platform of Peking or Wusong Station at the same time, it was a very shocking scene.

Of course, this high-density direct express marshalling group also led to the supreme dominance of the Republic Railway at that time. Like the Liaodong Peninsula, which was traversing on the Changda Railway, the gods blocked the gods and Buddhas blocked the Buddhas. No vehicle could survive in front of the pigs for more than 10 minutes.

At that time, when I chose a railway trip in the Republic, the most tragic thing was to ride an ignorant green-skinned car and slowly wander on the railway, but behind it was a murderous herd of pigs approaching quickly.

In the Xuzhou section of the Beijing-Shanghai Railway of the Republic, the pigs entering Beijing from Wusong, Nanjing, Suzhou and Hangzhou were similar in departure time and just formed the first line of the Xuzhou section, which made the famous thirteen pigs in Beijing-Shanghai, causing all the green and red pigs to be scared.

Generally speaking, whether the red-skinned or green-skinned car is targeted by a pig's herd, it is lucky to squat in a small station that cannot be called a name in a few corners and squat for two hours to "wait for avoidance" and rushing forward.

Liang Yuan’s last life was opened in 2004 after the new century. Now Fu Hengyu has to set a well-known benchmark for the Republic’s railway fifteen years in advance.

Liang Yuan thought about the possibility carefully and found that the simple plan Fu Hengyu just mentioned was extremely feasible. He used the direct special of Dongfeng 11G traction as a reference. Although due to the immature technology, the 25S traction led by the Long March 3 gas turbine locomotive had to be inspected in Xuzhou, which took 30-40 minutes, but the good acceleration of the Long March 3 locomotive would definitely catch up with this lost time.

After all, the Beijing-Shanghai Railway is not built according to the standards of high-speed railways. It has many line curves and can only maintain a speed of 40-80 kilometers per hour when turning. This frequent deceleration and acceleration happens to be a field that gas turbine locomotives are good at.

The birth of the pig herd was 15 years ahead of the 1980s, when air transport capacity was equally tight, I don’t know how many pig heads I had to hold on to this time, and it should be much larger than the 13 Beijing-Shanghai Pigs I knew in my previous life.

The green-skinned car on the night trip of the Beijing-Shanghai Line Xuzhou section is destined to be desolate. In the predictable future, squatting for three or four hours to avoid a large-scale pig herd is possible, Liang Yuan thought with a smile on his face.
Chapter completed!
