"Can the cost be reduced to $40,000? Can it be sold for $150,000? Lin Hongfei was taken aback, in his impression, aero engines seemed to be very expensive things, and he subconsciously asked, "What is the price of Pratt & Whitney's PT6A-11 engine?" ”

Lin Hongfei expressed his surprise, the price of 40,000 US dollars, converted into RMB is only more than 300,000 yuan, but the price of a middle-class car, you must know that the highest value of a civil light aircraft is the aero engine, a price of more than 1 million US dollars for a single light civil aircraft, the price of the engine seems to be 500,000 US dollars, accounting for more than half of the total cost of almost the aircraft, he really can't accept for a while that the price of an engine can be reduced to this extent.

But it was obvious that Chaprekin had misunderstood his boss's meaning, and he immediately said, "Boss, if you think the price is low, it's okay to sell it for $200,000...... The price of the PT6A-11 is $300,000, which is still the price sold to long-term cooperative customers. ”

Lin Hongfei really doesn't know the price of the PT6A series engine, but Chapregin, as a person who has been in this industry for many years, knows that this is not strange at all, but despite this, he still sighed, "It's really a huge profit." ”

Isn't it a huge profit to buy $200,000 for $40,000 of something, a full five times the profit?

Lin Hongfei sighed in his heart, but he didn't expect Chapregin to be very disdainful of Lin Hongfei's words, "What kind of profiteering is this?" According to our estimates, the cost of their PT6A-11 will not exceed $50,000, but they dare to sell it for more than $300,000, which is six times the profit, and the cost of PT6A-65AR will not exceed $80,000. But they sold for more than $1.2 million, and the profit was more than 15 times! ”

15 times the profit?! Lin Hongfei was stunned in an instant!

But the next moment, he drooled greedily: If you want to go up, you must go up!

15 times the profit, a fool wouldn't want it! Nima, making cars, is now considered a huge profit, but the profit of the manufacturer is only about 50%, and he has a sum with the Pratt & Whitney Company, and he simply doesn't want to live. It's no wonder that Pratt & Whitney can't produce thousands of engines a year and still be alive and well...... The self-pitying boss Lin didn't expect that in this era, how many industries can reach a profit margin of 50%?

Boss Lin, who originally planned to just play tickets, finally made up his confidence at this moment: the turbofan engine is too high-tech to take it slowly, but the aero engine must be on!

"From now on. This project is directly responsible to me! Lin Hongfei, who had never thought that something with high-tech content in the aviation field would have such a high profit, made up his mind in an instant. This project must be in your own hands! He stood up and said to Chaprekin. "What's next? Is it to find a platform to fly into the sky to test whether the performance of the engine in the air can meet the design requirements? ”

"Not yet," Chapregin shook his head, and the boss's words made him completely relieved: the status of the aviation laboratory is guaranteed, and it is directly responsible to the boss, which means that the administrative level of the aviation laboratory is only half a level lower than that of the group's head office, and it has jumped from a department with a potential existential crisis to the core department of the group. It's a big leap, but it's the news that Chaprekin likes to hear the most, "Next, it's a 150-hour validation test. After 150 hours of verification and assessment, it was determined that there were no problems before the experimental installation was carried out for flight testing. ”

"150 hours of non-downtime?" Lin Hongfei was frightened, 150 hours is 6 days and another 6 hours, continuous operation for such a long time, this is an aero engine, even if it is a large bypass ratio turbofan engine used in a large civil airliner, the continuous working time is only more than ten hours, as for 150 hours of continuous operation? That's going to burn out the engine.

"It is not 150 hours of non-stop, the engine used on large civil aircraft and large transport aircraft should be run continuously for 12 hours, and then run for 12 hours after an intermittent interval of 12 hours of repeated simulation tests, to simulate the actual performance of the engine under the conditions of high-intensity use in wartime, this small civilian turboprop engine is to run for 6 hours and rest for 2 hours to simulate, and after the total operation reaches 150 hours, you can find an experimental platform for installation and flight testing." Chaprekin explained to Lin Hongfei.

I see! Lin Hongfei then understood that he dared to say this in the engine test of the aircraft, the preliminary test alone is so strict, but it is natural to think about it carefully, if there is no such strict, such a high technical threshold, how to ensure safety?

……………………

Until Lin Hongfei left, Chaprekin never forgot to urge Lin Hongfei to pay attention to the development of material technology, "Boss, the improvement of aviation turbine power depends to a large extent on the increase of the total temperature before the turbine, and the increase of the total temperature before the turbine depends on the high-temperature resistant alloy materials, you must build the metal materials research institute as soon as possible." ”

"Don't worry, I'm just engaged in machinery, of course I know the importance of materials," Lin Hongfei nodded, he was suddenly a little curious, "Lao Cha, how significant is the total temperature before the turbine to improve the performance of the engine?" ”

"Very significant, so significant that you may not imagine," Chapregin has known his boss well enough during this time, although the gap between the piston internal combustion engine and the turbine is not on the same level, but the old cha is an exception to this freak, he is a person who engages in piston aero engines, and needs to have considerable knowledge of piston internal combustion engines and corresponding aviation technology, hearing this, he immediately said, "The total temperature before the turbine is increased by 55 degrees Celsius, under the condition that the engine size and fuel consumption remain the same, The thrust of the engine can be increased by 10%. ”

"So...... Terrible? ”

Lin Hongfei is very aware of the importance of materials, but he really didn't expect that in the aviation field, the importance of materials would be so important...... With the same design and different materials, two engines with very different properties can appear.

"yes. The material is indeed very important," Chapregin nodded with emotion, "Pratt. The turbine inlet temperature of the PT6A-11 of the Whitney Company is 954.3 degrees Celsius, the turbine inlet temperature of our engine is only 950.2 degrees Celsius, and the turbine inlet temperature of the military turbofan engine with a thrust-to-weight ratio of 10 that the Americans are engaged in can reach 1580 degrees Celsius to 1680 degrees Celsius...... If we had a material that could withstand a total pre-turbine temperature of 1280 degrees Celsius, how much better would we be able to improve the performance of this engine without making the slightest changes to the design of this engine? ”

"!" Lin Hongfei is no longer going to calculate. He gritted his teeth and stomped his foot, "I'll do this when I go back!" ”

————————————————————————

Lin Hongfei said so, and did so, and directly aimed at the current situation of domestic materials research: because of the embarrassment of national finances and the continuous reduction of investment in scientific research, many national materials research institutes have suspended a large number of scientific research projects. Scientific researchers are in a situation of absolute irony that "it is better to sell tea and eggs than to build an atomic bomb."

This is still the atomic bomb, which is used as a material for basic research. Naturally, it is even less appreciated...... Materials study this thing. From the beginning of the project, it is really impossible to say when the results will be produced.

After going back, Lin Hongfei immediately called his father-in-law, "Dad, our company has produced our own turboprop engine, but there are still some deficiencies in high-temperature resistant metal materials. We plan to set up a materials research institute, the main direction is metal materials and materials, can you introduce a domestic expert and research institute in high-temperature resistant aviation metal materials to me? ”

On the phone, Lin Hongfei bluntly said to the East.

"Your company actually made its own aero engine?" Dongfang Zheng's tone was full of surprise. "Did I hear me right?"

Like most people, the impression of the Dongfang secretary on the aero engine is also a collection of "high-tech, technical content" complex, even if the republic's aero engine industry is not developed, but it is one of the few countries in the world that can independently manufacture aero engines for both military and civilian purposes, and it is definitely not a company like Guqi Provincial Industrial Manufacturing Co., Ltd. can produce it...... Then again, how long has it been since the production line of the aircraft engine, which their company received from the Zaporosh Progressive Machine-Building Bureau, is now in production?

"Well, you heard it right," Lin Hongfei said, "the test has just been completed, and the next 150 hours of testing will be carried out, and then the air flight test will be conducted...... However, this engine is already a product of the Zaporosh Progressive Machine Building Bureau, it is not a completely new design, and there are no technical problems. ”

The deputy leader of Dongfang was silent for a moment, and hesitated, "If I'm not mistaken, the engine that your company introduced from the Zaporosh Progressive Machine-Building Bureau is a small turboprop engine and a small turboshaft engine, which are used in small fixed-wing aircraft, light helicopters and UAVs respectively, right?" Is it used in our country? ”

If there is a market demand for his son-in-law's aero engine, of course he will help within his ability, but if there is no market demand, he is not good at pulling hard...... In his position, if he doesn't seek to be motivated, as long as his ass is not crooked, he basically doesn't have to think about any impact issues, and he can act unscrupulously, but if he wants to be motivated, he must pay more attention to all aspects, unfortunately, Secretary Dongfang's self-motivation is not small, and the conditions are not bad.

"There is a market demand," on the way back, Lin Hongfei had already figured out the purpose of this aircraft, and now when he heard his father-in-law ask, he immediately said, "The size of this engine is the same as that of the Canadian Pratt. Whitney's PT6A is almost the same in size, and it can be directly used on our Y-12 transport aircraft, fully replacing the PT6A engine used on the Y-12. ”

"Can it replace the imported engine used on the Y-12?" Dongfang's deputy team leader, who was still full of hesitation just now, suddenly became excited.

He couldn't help but be thrilled that aero engines were highly profitable products, although he didn't know that every product from Pratt. How much precious foreign exchange does it take for the Whitney Company to import a PT6A turboprop engine, but there is no doubt that if the engine designed by Lin Hongfei can really replace the PT6A in its entirety, how much can be done with the foreign exchange saved? The only thing he cares about now is, "Can it really replace PT6A?" How far does your engine compare to the PT6A? What about the price, how much of an advantage? ”

"It's still a bit of a gap," although I am very reluctant to say that my products are inferior to others, but this is the case, Lin Hongfei still has to answer his father-in-law's question head-on, "Yun 12 uses the PT6A series of 27 type, the engine power is 462 kilowatts, and the power of our engine is 330 kilowatts......"

Speaking of which, Lin Hongfei couldn't help but feel that the performance data of his products was a little cold, compared with others' Pratt & Whitney, the difference was almost one-third! This made Boss Lin a little shy, but soon said, "But this data is similar to the 11 type of PT6A series, I guarantee that the Yun-12 can fly like our company's engine, but the load is not as much as before, but our price advantage is very large, only less than half of the PT6A-27, and it is expected that the improved model will be able to reach 380 kilowatts of output power next year." ”

"The gap is too big...... Dongfang Zheng thought in his head for a moment, and finally shook his head, his tone full of regret.

Lin Hongfei was suddenly a little depressed, sigh......

But before the words fell, Dongfang Zheng's voice sounded again, "However, I said Hongfei, aren't your company partners with Bingfei, which produces the Y-12 transport aircraft, I can help say hello, but you can discuss the specific things in detail yourself." ”

"As for the ...... of high-temperature resistant aviation metal materials," Speaking of this, Secretary Dongfang thought for a moment, "In this way, you go to the Chinese Academy of Sciences to find Mr. Shi Xuchang, he is our country's authority in metal materials, especially aviation high-temperature resistant metal materials, was one of the 35 scientists in the early days of the establishment of the Republic of China, the US government strictly ordered not to return to our country, you go to him, yes." ”
