"Mom, why don't you tell me about my dad, he doesn't know how to drive the nose, which door to ride. Liang Yuan complained in a low voice.

"Your dad said that the Long March 3 was something made by his wife and children, and if he didn't go to take it during the test run, who would take it?"

"Xiaoyuan, do you think what my mother said will work?" Li Yuanling asked rhetorically.

"Uh....... Liang Yuan suddenly felt speechless.

With Comrade Liang's temper at work, both Li Yuanling and Liang Yuan are just talking in vain.

"Some time ago, the rectification line, your uncle bought a lot of laser levels in the depot to measure the flatness of the modified track, as long as the structural strength of the nose is enough, it will not run and run halfway to disintegrate, and other subversions, fires, explosions, are basically impossible, Xiaoyuan can rest assured." Li Yuanling patted Liang Yuan's cheek and said warmly.

Generally speaking, the structural degree of the locomotive should be less than the maximum real yàn degree, and the structural degree of the bottom of the locomotive should be greater than the maximum real yàn degree, as long as the track flatness is qualified, purely in terms of the nose structure, even if the new Long March 3 is pulled up to 2oo km/h, there will be no disintegration, it is nothing more than the acceleration of wheel and rail loss.

Hearing Li Yuanling say this, Liang Yuan put his heart back in his stomach, some time ago Liang Yuan has been busy preparing for Yuanjia's big meeting and tinkering with electromagnetic guns, and Liang Yuan really hasn't paid much attention to the preparations before the Long March 3 test run.

"Xiaoyuan, mom saw that you recruited Qilianshan and them back from Europe a few days ago, and brought in many foreigners, and also approved four Casbauer and two Toyotas. Could it be that Xiaoyuan plans to recruit people from abroad to form the technical force of COMAC?" Li Yuanling asked curiously.

"Mom is amazing, just guess and know my plan. Liang Yuan smiled and slapped his ass.

Li Yuanling is engaged in turbine research work in China, and has inextricable links with the aviation industry of the Republic, in addition to the integration of the MPC75 team of Xifei, Li Yuanling knows that Liang Yuan has not made any big moves in China, as long as the Long March 3 test run is successful, Liang Haiping will resign from the director of the car factory and focus on the side of COMAC.

In terms of normal work progress, it is time to set up a production technology team, and since Liang Yuan has not made any moves in China, he must have focused his energy abroad.

Li Yuanling lowered her head and thought about it. I didn't figure out where Liang Yuan went. In order to get thousands of qualified aeronautical engineers, looking at his son's smile, Li Yuanling also knew that he couldn't ask anything, so he could only glare at Liang Yuan angrily. I casually pulled someone's ear.

It is 15 km from Linshengborg station. A milky white tractor with dark blue stripes swept past an iron-gray pit stop signal. The pad ash brought up by the locomotive formed a clear trail of smoke and dust behind the direction of travel.

Under the signal, the two employees of the electrical section of Linshengbao Station, who were responsible for checking the signal status, turned around, looked at the white locomotive that was gone, and cursed.

"Da Linzi, the big guy who just passed can have at least 16o. ”

The middle-aged man called Da Linzi spat at the mouthful. said: "MD, I almost poured Lao Tzu with a mouthful of furnace ash." ”

"Da Linzi, have you appeared, this machine head is a little strange, so fast, it passed without any sound, it was too quiet. ”

"Old Song, it's a bit strange for you to say this, the movement of this car is only slightly larger than the electric locomotive I have seen in the mining company before, but there is no power supply network here?"

Da Linzi pointed to the empty sky above the railway line suspiciously.

Although the noise of the helicopter is quite huge, most of the sound heard by humans on the helicopter is made of the rotor and the driving rotor moving parts, and the turboshaft motor has nothing to do with it.

Later, Bombardier Canada used a gas turbine locomotive with a turboshaft motor as the power core, and the noise of the locomotive was the same as that of the electric locomotive when operating under high loads, and much lower than that of the rumbling diesel internal combustion engine.

In the cab of the Long March 3, there is no rumbling sound that is customary for ordinary diesel locomotives, and a slightly high-pitched hissing sound fills the entire body.

Big car (Note 1) Wang Shubin stared nervously at the scale gauge on the dashboard, the white hands of the computer swaying slightly at the position of the 16o scale.

"Duan Chang, can this car really run to 18o?" Wang Shubin asked.

Although soon after coming out of Liaoyang Station, the Long March 3 has been maintaining a degree of 16o km / h, but for the degree of 18o km / h, Wang Shubin still feels that he has no bottom in his heart, 16o km / h can be said to be a quasi-high railway, and in the eighties, 18o km / h can be completely classified within the scope of the high railway.

"No problem, what our car factory has researched by itself, saying that it can run 18o, it will definitely be able to run 18o." Liang Jiangping said in a certain tone.

The crew of the Long March 3 has always been served by employees of the Benxi train depot.

Glancing at the white boundary stone of "Long Railway -- 362 km" flashing outside the train window, Wang Shubin slowly pushed the locomotive's throttle lever to the maximum position.

The response was almost instantaneous, accompanied by the hissing of the vortex engine in the cab, a push back sensation came in an instant, and the white hands on the scale sheet swept over 165 and 17o at a very fast speed, heading straight for the position marked 18o.

"Good fellow, this car is just too fast. Wang Shubin sighed with emotion, and put away the throttle push lever in his hand as he spoke.

Thanks to the Jewel Vortex Shaft Motor, which can withstand a load output of 1.5 times the rated power, the Long March 3 was reinvented extremely quickly, from 16o km/h to 18o km/h in less than 2O seconds.

"Dongfeng 4B traction standard marshalling in the straight section to add to 1oo km / h at least 15 minutes and more than 3o km distance, replaced by this car I see two minutes, five kilometers to the sky. Zheng Nan, the deputy car, took a pen and counted a few numbers on the driver's platform.

"It's just that the fuel consumption is too high. Liang Jiangping thought thoughtfully.

"The passenger version of Dongfeng 4B only uses more than half a ton of diesel fuel for an hour. Changing to Changzheng-3 can burn more than half a ton in half an hour. Liang Jiangping pointed to the fuel gauge on the bridge.

"Duan Chang, you have to calculate it like this, the sustainability of a single Dongfeng 4b can run up to eighty, although we haven't tried how much this car can run on the standard group, but look at the cool strength of this car, I must have no problem with about one hundred or four, five." ”

"The loss of the embankment is replenished, not to mention the freight, I think the passenger transport is absolutely good, but I don't know what price the depot sets to sell to the road bureau, and what is the machine failure rate. Wang Shubin said unsatisfactorily.

Liang Jiangping listened to Wang Shubin mention the cost. I couldn't help but smile wryly. The Dalian Locomotive Factory's latest Dongfeng 4B is only 4 million units, and the four jewel scroll shaft engines on the Long March 3 cost 1.2 million US dollars.

Even according to the official exchange rate of the Republic, the price of these four gem motives is already more expensive than a Dongfeng 4B diesel locomotive, unless his wife and children can completely localize the gems. Otherwise, it will certainly be impossible to equip the Long March 3 in large quantities.

But Liang Jiangping thought about it. Pull out a high traction head at random abroad. The catalogue price is more than five or six million US dollars, as long as Brilliance can localize the gemstones, solve the problems of high-temperature exhaust emissions and the durability of the nose. Even if the fuel consumption is higher, it is the most ideal plan for the Ministry of Railways to break through the high railway threshold.

Liang Jiangping was thinking about the various technical problems of the Long March 3, and Wang Shubin's slightly excited voice sounded in his ears.

"Duan Chang, we'll be in Linshengbao soon, should we add some degrees?"

Through the windshield of the Long March 3, the buildings of Linshengbao Station are already faintly visible, and from a long distance, you can see that the No. 1 platform of the station has been completely submerged by continuous colored flags, and the black pressed figures are constantly surging under the color flags.

Squinting slightly, listening to the hissing sound of the jewel motive, Liang Jiangping thought about the evaluation of the nose of the Long March 3 by Jürgen Christopher, head of the East German expert group who participated in the design of the Long March 3 -- in terms of design, degree, and manufacturing, the Long March 3 is a fully qualified high-speed railway traction locomotive.

"Increase the degree to 2oo, Zheng Nan keeps an eye on the changes in car conditions. Liang Jiangping decisively patted the driver's platform in front of him.

"Okay, Duan Chang, as long as we don't overturn this section, we will definitely be able to be on the news network. Wang Shubin said heroically.

As Wang Shubin pulled the throttle lever to the end, the crackling sound of various flying insects hitting the windshield of the locomotive became more and more intensive.

"Xiaoyuan, the Long March 3 looks so beautiful after being painted white. Shyness has gone to normal, Ning Wanjia returned to Liang Yuan's side, and pointed to a semi-streamlined nose at the southern end of the Linshengbao platform that was approaching.

The last time the three of them saw the Long March 3 was in the early winter of last year, when the entire nose was installing internal equipment, and the car body was only painted with old red anti-rust paint, which looked extremely obscene.

"Jiajia, why is this traction locomotive a little weird, it looks like a little pig if you look closely. Ning Wanfei pointed to the two round headlights under the windshield of Long March 3 and said.

As soon as Ning Wanfei said, the more the two girls looked at the front of the car, the more they looked like pigs with pouting noses.

Since the Long March 3 is defined as a quasi-high traction locomotive, how can Liang Yuan let the depot find a Dongfeng 4B car body to install a real machine, and casually sketch the appearance of the Dongfeng 11G diesel locomotive in the later generations and throw it to Liang Haiping, and the name of the Dongfeng 11G in the railway system of the Republic is the pig's head.

"Pig head, shouldn't it be designed in your own image? Ning Wanjia looked Liang Yuan up and down.

The twins know a lot about the ins and outs of the Long March-3's appearance.

The two smiling girls first pinched Liang Yuan's ears one left and one right, and then squeezed Liang Yuan's mouth and nose with their small hands, looked at someone's new look and looked at the galloping Long March 3, the two girls finally squatted on the ground with a smile covering their stomachs.

Even if someone was lucky, Liang Haiping took Liang Yuan's sketch and convened a meeting of experts and technicians of the depot to study how to achieve it, Jurgen Christopher took the drawings and looked at them for a long time, and told Liang Haiping that the appearance of the traction locomotive drawn in this sketch is very similar to the 252 type fast electric locomotive currently under development by the consortium, and the molds and production equipment of the car body can be imported from the consortium.

The 252 type fast electric locomotive is a new version of the electric locomotive developed by the German Republic of Germany with the technical support of the Federal Republic of Germany, based on the Federal Republic of Germany's 12O type high electric locomotive, the locomotive structure is 16o km / h, and the more advanced AC-DC-AC mode of transmission is adopted.

At this time, the Union Shopping Center in Berlin has become the biggest revolutionary achievement and beautiful socialist window of the East German General Secretary Ancona, and in the case of a large amount of dollars to open the way, Liang Haiping's small request was effortlessly approved by the Central Planning Commission of the GDR, and the body production equipment and structural drawings of the Type 252 fast electric locomotive were transplanted to the Long March 3 gas turbine locomotive after slight modifications.

Comrade Lao Liang also knew that the structure of the nose of the Long March 3 had a profound technical relationship with the 12O high-electric locomotive of the Federal Republic of Germany, so he dared to make a decision to pull the nose of the Long March 3 up to 2oo km/h, and in the Federal Republic of Germany, the 12O high-power locomotive once ran 28o km/h.

Although there are a lot of West German 12O high-electric locomotives, Liang Haiping still decided to use the shape of the Dongfeng 11G drawn by Liang Yuan on the front of the Long March 3 locomotive, after all, the Dongfeng 11G of the Republic was designed in the 21st century, which is 20 years later than the 12O electric locomotive designed in the mid-80s, and the former Dongfeng 11G is much better than the 12O electric locomotive in terms of aerodynamics alone.

Hum-hum--, two short whistles suddenly started, and the gas turbine locomotive in the rush was like a violent tornado, and it only took one breath to cross the platform more than 100 meters long at Linshengbao Station, and quickly went away with a large puff of smoke and dust, leaving behind a group of stunned people.

Except for Liang Yuan, Zhao Tiemin, Liang Haiping and a few others, no one in the Republic in the 80s had experienced how shocking it was when a 2oo-kilometer train rushed past with the sound of steel crashing, and it took five or six seconds, except for the unique hissing sound of the Long March 3 power system, and there was silence on the long platform.

"Minister Fu, 2o2.17 km/h, 2o2.17 km/h, the Long March 3 broke all locomotive records since the founding of the People's Republic of China and successfully entered the field of high-speed railways. The technician in charge of measuring the nose of the plane broke the silence on the platform with a slightly trembling voice. (To be continued!)

Yesterday I had a bad stomach after eating hemp snacks, and I hung a bottle of water in the community, and today is good, and I will compensate for it with a big chapter.
