Li Yuanling thought for a while and said with a smile: "Okay, last month, the material team complained about the lack of funds, and the people and materials can be allocated to you, but in the future, their scientific research expenses will also be paid by you." ”

Liang Yuan pretended to be heroic and said: "It's only a few small dollars, and my mother and I are so clear." After speaking, Liang Yuan suddenly remembered that even if he didn't mention Li Yuanling, he would separate the material group, process group and other auxiliary groups, and the equipment of the Northeast Locomotive Factory was simply a special equipment prepared for the production of Spey engines.

There are 112 metal material grades used in Spey aero engine, and there are as many as 16 kinds of superalloys alone, such as high and low pressure plates, compressor blades, power turbines, etc., which must use vacuum smelting devices to manufacture qualified metals.

Helplessly, he patted his head and Liang Yuan put on a bitter gourd face and said, "Mom, I don't have to fool people like this when I fight local tyrants, I'm also very poor now." ”

Li Yuanling twisted Liang Yuan's ears with a smile and said: "Your uncle has recruited all of them, last month, the daily consumer goods in the Suifenhe market alone earned more than 10 million, and you take out the odds and turns to spend them for a while." ”

"But your equipment is very good, give my mother three or four years, and it is possible to completely localize the gas turbine. ”

Although the Spey engine was introduced earlier, the progress was slow due to the lack of research and development costs for Spey's supporting aircraft, the J-7. Therefore, the localization of Spey engines has been at a standstill.

In order to continue the development of the Jian-7, the impoverished navy even tried the bad idea of advertising in the Hong Kong Military Weekly to recruit cooperative investors, but unfortunately the effect was about nothing. It was not until after the Sino-Vietnamese Naval Battle in 88 that the Nansha Islands were faced with an urgent need for long-range aircraft cruises, and the Navy made a painful decision to support the Jian-H-7 project alone.

However, this did not change the fate of the Spey engine, after the successful test flight of the J-7 in 93. Due to the fact that Rolls-Royce has discontinued the production of Spey engines, and the localization of Spey is far away, the sound of the J-7 replacement was once in the world. After three years of quarrels, it was not until 96 that it was established that the Spey J-7 remained unchanged.

The real localization of Spey engines began to be developed rapidly around 1997. After 7 years of hard work, in 2003, the domestic Spey engine was finalized and entered the stage of mass production.

Liang Yuan was pleasantly surprised when he heard Li Yuanling say that he could complete the localization of gas turbines in three or four years, and the parts exchange rate of Spey gas turbines and Spey aero engines exceeded 70%, and the parts exchange rate of core engines exceeded 90%. If the localization of Spey aero engines is carried out on the basis of completing the localization of Spey gas turbines, it will take about one or two years to do so.

"Mom, is it really fake?" asked Liang Yuan with some disbelief.

"Your grandfather Wu said that the overall blade casting technology of Shengjing Metal Research Institute is about to make a breakthrough. The processing volume of blades accounts for one-third of the entire gas turbine, and if you ensure that every month, the profits of daily consumer goods in the Suifenhe market will be transferred, and the mother will be able to complete the localization of the gas turbine in three years. Li Yuanling said while stir-frying the hairtail fish in the iron pot.

At least 360 million in three years, Liang Yuan smacked his lips. The heart said that this thing really kills people. However, the profit of the gadget is also really high, and after the installation of the J-7 in the mid-nineties, the short-term consumption of Spey will be at least about 200 units, and the long-term consumption is more likely to exceed 1,000 units. Counting inflation, a domestic Spey can sell at least 10 million units, and the thrust of the Spey engine is about the same as that of the Spey engine. On top of our large purchases, it would cost us $2.5 million to get one.

360 million for 20 billion, no matter how you look at it, it is a lucrative deal. As for the cost, with Liang Yuan's technology and equipment in hand, it is probably only to pay some ore, manpower, and electricity costs. But how should the state tax itself at that time, Liang Yuan thought unconcernedly.

The next day, Li Yuanling, who compensated Liang Yuan for a meal, plunged into work, and even took Wu Zhonghua and Liao Min to go home late at night every night.

On October 18, the vacuum smelting furnace and vacuum refining furnace in the metallurgical chamber were finally successfully put into use after more than a month of installation and commissioning.

On October 25, Su Liangyu took more than a dozen people who developed the HT680 microprocessor together to Shengjing, and Liang Yuan only found time to have a meal with Su Liangyu on the weekend, and then threw the rest to Liang Haiping in the name of preparing for the midterm exam.

On November 3, Liang Yuan, who had completed the mid-term examination, was finally brought back to Benxi by Liang Haiping, and the reason was extremely sufficient -- the first DBme double-decker passenger car of the Northeast Locomotive Factory was successfully rolled off the assembly line.

Under the push of Dongfeng 5 shunting machine, the DBme double-decker passenger car with beige and dark sea blue coating slowly drove out of the tall assembly workshop of the locomotive factory, and after the bottom of the car arrived at the designated position, the deafening firecracker sound suddenly sounded, Liu Changhe, director of the Shengjing Railway Bureau, Qin Yalian, director of the Dandong Railway Branch, Qu Zhaoguo, deputy mayor of Benxi City, and Liang Jiangping and his party of four picked up scissors and cut off the red silk hanging in the carriage port several meters long.

Liang Yuan looked at the lively scene in front of him and almost didn't have fun, he mentioned it when chatting with his uncle, when the first locomotive came off the assembly line, there was a grand ceremony, how to prepare, but he didn't expect that the uncle was directly used in the off-line ceremony of the double-decker passenger car.

The treatment of the double-decker car is different from the 243-type electric locomotive that has been coldly treated, and the 25A-S double-decker car developed by the Nanjing plant can be said to be a failure, and there is no sign of success in the short term, so the Ministry of Railways has great expectations for the Northeast Locomotive Factory to introduce the East German DBme double-decker passenger car. Although the Northeast Locomotive Factory is a collective enterprise and is not welcomed on weekdays, it is also the Ministry of Railways' own children in the general direction.

Liu Changhe, director of the Bureau of Railways, who attended the ceremony, talked with Liang Haiping for more than 30 minutes before cutting the ribbon, and specially conveyed the concern and greetings of the leaders of the ministry, hoping that the bottom of the Northeast Locomotive Factory could be tested along the Beiping Ring Road, and the ministry had even prepared the regular number of the bottom of the car 25B-S.

Liang Yuan complained about this strange number, and at the same time listened absentmindedly to the gushing speeches of the leaders on the stage. In the future, the traction locomotive must think of a number by itself, Liang Yuan thought angrily, thirty minutes later, the off-line ceremony was finally completed, and the team walked bustling towards the locomotive factory guest house.

Liang Yuan turned around and was about to leave to go to the guest house to eat and drink, but he unexpectedly found that Su Liangyu was with three people, pointing and talking about something around the bottom of the double-decker car.

Liang Yuan walked over curiously and asked, "When did you come, Lao Su?" Why didn't you tell me, I knew I was here with you." ”

Su Liangyu smiled and said, "I've been here for three or four days, and who knows if you finished the exam at that time." (To be continued......)
