Chapter Errors/Click here to report

Liang Yuan watched Liang Jiangping write the 1.9 mm crack in the report, in fact, if this matter is handled smoothly, it can be digested within the sub-bureau, anyway, on the bright side, it is the oil supply rack and pinion card of the machine head, and the old comrade Liang wrote down this problem and sent it to the road bureau, so that the sub-bureau and Datong Locomotive Factory can go to the skin.

But now the nature of the rift has changed as soon as it is written in the report, from affecting the image of the national railway to a serious safety accident, it is estimated that all the rewards of the entire Andong Branch in the second half of the year will be in vain, plus it is an international train accident, and the branch will be named and notified by the Ministry of Railways, and his father's ability to pull hatred is really strong.

Liang Yuan couldn't help but ask after all: "Dad, if this report is handed in, the bonus of the sub-bureau in the second half of the year will be in vain, right?"

Liang Jiangping nodded and said: "This is simply a crime, what are the inspectors and maintenance of the sub-bureau doing, such a big crack is definitely not caused by the mileage from Anton to Tongyuan Fort, I have to focus on this matter tomorrow in the paragraph." ”

Liang Yuan looked at Liang Jiangping's indignant appearance, and thought to himself that it would be better not to mention the Jian yì that had been digested within the sub-bureau, and if he put it forward, he would probably be criticized by Comrade Lao Liang, anyway, he didn't expect his father to soar, and it would be God's blessing to be able to sit firmly in the position of the section chief. Toss as much as you like.

However, as soon as Comrade Lao Liang did this, the Datong Locomotive Factory was liberated, and in the face of a serious traffic accident in which the whole train could be destroyed and people died, the problem of supplying oil and pinion became not worth mentioning.

The next day, Liang Yuan stood on the temporary rostrum in the school gymnasium, and read a speech on Wencheng Wude and bird and fish soup of the Municipal Education Bureau to the leaders of the Municipal Education Commission, which was a perfect end to the fact that Benxi City entered the finals of the Youth Science Competition for the first time.

On June 20, Liang Yuan, who had been dangling in Benxi for three or four days, said goodbye to the two lolis and returned to Shengjing.

Liang Yuan sat on the sofa and looked at Li Yuanling, who was frowning, and his thoughts were spinning.

The number of units of Spey's gas turbine has already come out, and as Liang Yuan expected, compared with the original Spey S_MA1 gas turbine, the number of units in the domestic version is a bit miserable.

Compared with the maximum power of 13,800 kW of the original Spey gas turbine, the maximum power of the domestic Spey gas turbine barely reached 9,500 kW, and the fuel consumption rate was 62 higher than the 235 g/kWh of the original Spey, and finally stabilized at 297 g/kWh. This means that when making ship power, under the same power output, the domestic Spey gas turbine consumes 14 tons more fuel per day than the original Spey.

Liang Yuan took the unit's first ignition number from the coffee table and looked at it carefully.

After 72 hours of ignition operation, the third and fourth blades of the compressor were slightly damaged, the structural metal fatigue appeared at the F50 of the gas turbine rotor, the power turbine was overheated occasionally, and the seventh and twelfth seals of the exhaust system were burned......

After 72 hours of operation, the unit has accumulated 17 heavy structural component damages, 59 large component damages, 185 general component damages, and minor .......

Wounded, Liang Yuan closed Sibei's record report and put it back on the coffee table. According to the report, after 72 hours of ignition operation, the unit was overhauled.

Wu Zhonghua let out a long sigh, pointed to the report on the coffee table and said, "The situation of the crew is very strict, and it will take at least half a year to deal with these problems." ”

Li Yuanling picked up the report and pointed to the structural damage of the heavy dà and said: "The situation of metal fatigue in a short period of time like a rotor is simply the result of the blind modification of the axial force of the 423 factory S_MA1. ”

Wu Zhonghua shook his head and said: "Now only 423 Factory is investing in this project, Xiaoling, if you want to modify the design of 423, it is equivalent to completely denying the work of 423, which is equivalent to suing 423 for the failure of this whole machine test, the responsibility is all on you, and 423 will never agree." ”

"However, the teacher's current house is crooked at all. ”

"I know that this house is crooked, but unfortunately for the time being we have no other source of funds to rebuild a prototype, at the moment we can only make significant modifications on the basis of the 423 design to rationalize it, like the axial force of the rotor mentioned by Xiaoling just now, we can solve the problem of metal fatigue by increasing the diameter of the rotor, of course, the specifications of the components that are matched with the rotor also need to be changed, which requires a lot of practical calculations. ”

Liang Yuan suddenly realized that all the incomprehensions in his previous life suddenly became clear. It is no wonder that in the previous life, Wu Lao did not improve the life of the gas turbine until his death, according to what Wu Lao said now, it is equivalent to re-developing a gas turbine, and the original Spey S_MA1 drawings in his hand are equivalent to waste paper. However, in two years, Wu Lao raised such a dilapidated unit to 300 hours of first life, which can be regarded as a genius, you must know that the British developed the Spey gas turbine, and it took 12 years to finally succeed when the budget was sufficient.

It's a pity that God didn't give Wu Zhonghua enough time, and he fell short after all.

"Teacher, is there any news from the navy?" Li Yuanling thought for a while and changed the topic.

"For the time being, there is no final decision, in the future, Xiaoling will take the project team with peace of mind, and I will run the problem of funds. ”

"How can that happen, the teachers are so old," Li Yuanling said with some worry

"Go out to run for funds, the old face of the teacher still has some effect, Xiaoling, you are too young to do this kind of work for the time being. ”

Listening to Li Yuanling and Wu Zhonghua's planning for the future of the Spey project team, Liang Yuan's head was full of countless thoughts, now that the uncle has 10 million in his hand, at least so much can be transferred from the 257 factory in July, and many parts of the gas turbine in the 909 institute can continue to be used, according to Li Yuanling's idea, it will cost about six or seven million to build a prototype, but it will also cost some money to kick the 423 factory away from the-stirring stick.

Liang Yuan, who has memories of his previous life, understands that what Li Yuanling said is correct to tear down and start over. First of all, it is completely imitated according to Spey's drawings -- "completely localized---" slightly improved, and in the development of gas turbines, it is the safest to follow this path that has been verified by the Japanese Naval Self-Defense Force in the previous life.

Funds are not a problem for the time being, but how to mention it to his mother, Liang Yuan thought tangledly.
