"Boss, our own turboprop engine has been built......" Lin Hongfei, who had just finished negotiations with the General Staff Headquarters, the Commission of Science, Technology and Industry for National Defense, and the Ordnance Industry Corporation, received a call from Chapregin as soon as he went out, and Chapregin was so excited that he was almost speechless on the phone.

"Really?" After receiving this call from Lao Cha at the same time, Rao is Lin Hongfei has always been cool-headed and almost never convulsed...... The reason why it is "almost" instead of "all" is because we all know that occasionally Lin Hongfei will have convulsions at the same time...... His hand suddenly shuddered, "Really made it?" ”

Although there is a full set of production equipment, skilled workers, and a team of experts and engineers purchased from the Zaporosh Progressive Machine-Building Bureau, which is equivalent to bringing the production, manufacturing and R&D team of small turboprop engines and small turboshaft engines of the entire Zaporosh Progressive Machine-Building Bureau to the Republic, and at the same time purchasing a lot of special alloy materials, Lin Hongfei still can't believe that the first turboprop aero engine belonging to the Guqi Provincial Industrial Manufacturing Co., Ltd. was manufactured so quickly.

Although the technology and patents were purchased from the Zaporosh Progressive Machine Building Bureau, since they have already been bought, they are not their own! Lin Hongfei saw it very clearly.

"Yes, yes, we made it, we really made it!" Chaprekin nodded again and again, as the person in charge of the aviation laboratory, only Chaprekin knew how these people came over, and it was of course an exaggeration to stay awake, but everyone spent more than 12 hours in the laboratory every day, and everyone was working hard, "The test machine has just completed the first test run, and the ignition is very successful, and all the technical indicators have met the design requirements, which is very successful!" Very, very! ”

He was so excited. So much so that he used two very successful ones to express his excitement, and the whole person cried with joy.

All the experts from Ukraine, Belarus and other former Soviet republics know one thing in their hearts: their bosses seem to be hesitant to invest in aero engines.

This hesitation is fatal, because it also means that these people are not as important as he said in the eyes of their bosses, and if they want to prove their worth and not let themselves return to the embarrassing state of life before, the only way is to prove their worth in this way, for aero engine experts, what is the way to prove their worth? It was undoubtedly the fastest way to come up with the best products, and now, they have done it. Although this small turboprop engine, which has not been named for the time being, is not the best, it is only because the original design of the Zaporosh Progress Machine Building Bureau was such that the speed was absolutely top-notch.

Of course, Lin Hongfei doesn't know this, maybe even if he does, he will use this opportunity to "squeeze" these aviation experts from the former Soviet Union as much as possible, but at this moment. He asked eagerly, "How's the performance?" How much does it weigh? What is the maximum power? What is the fuel consumption rate? What is the refurbishment life? ”

Since taking over the entire team of designers of small turboprops and small turboshaft engines of the Zaporosh Progressive Machine Building Bureau. Lin Hongfei made up for his knowledge of aero engines. Now his knowledge of aero engines has finally reached the level of a military enthusiast.

"Weight 151.5 kg, maximum power 330 kW, take-off fuel consumption 0.42 kg / kW. , cruising fuel consumption 0.37 kg / kW. "Chaprekin's voice was excited, very excited. "Maximum refurbishment time 3500 flight hours, boss, we ...... We...... Succeeded......"

The agitated Chaprekin couldn't speak anymore and couldn't cry anymore.

Lin Hongfei's mind quickly emerged as a representative of this kind of small propeller engine: the Canadian Pratt. Whitney's PT6A series of 11/11AG small turboprop engines are equipped with new performance figures: weight 148.8 kg/149.7 kg. The maximum power is 373 kW, and the take-off fuel consumption rate is 0.394 kg / kW. The maximum overhaul time is 3,000 hours, but it is said that the maximum overhaul life of the newly produced PT6A-11/11AG can reach 5,000 hours. Compared with Whitney, an old aero-engine manufacturing giant, the gap in technology is still obvious, and the technical indicators are weaker than Pratt & Whitney's products. The lowest power turboprop engine in Whitney's PT6A series, the maximum power of the PA6A-34/36 model of the same series can reach 559 kilowatts, but the weight is only 150.1 kilograms, which is only 1.3 kilograms heavier than PT6A-11/AA4G, but the power is 186 kilowatts larger.

Speaking of which, the power of 330 kilowatts is really not high, and the top flagship engines of major automobile manufacturers more than ten years later, such as Mercedes-Benz S600SEL, BMW760LI, Audi A8L, etc., can exceed this maximum power of the engine, but Rao is so, Lin Hongfei is still very excited.

Not for anything else, just because this is the company's first real aero engine product, although the gap between performance and Pratt & Whitney is not small, but it directly solves the problem of having and not, solving the problem of having and not, and the rest is only the problem of poor technology...... It can be solved after all.

What's more, this is just a small turboprop engine, and you can't expect it to compare with the 10,000-horsepower turboprop engine used on the Tu-95 strategic bomber.

"Lao Cha, you wait, I'll go over right away!" Lin Hongfei dropped such a sentence to Chapregin, turned around, and hurriedly said to Yang Taiping, who was waiting for him when he opened the car door, "Go to the airport, go to our aviation laboratory immediately." ”

————————————————————————

Lin Hongfei, who rushed to the aviation laboratory in Beijun City as soon as possible, after entering the aviation laboratory, saw at first glance the small turboprop engine that was specially placed by the experts of the laboratory three meters at the entrance of the large laboratory, and which was produced by the aviation laboratory of Guqi Provincial Industrial Manufacturing Co., Ltd. and had all the intellectual property rights and patents, although the reducer in the front section and the various pipes all over the rear engine fuselage made this guy look a little complicated, But this did not affect Lin Hongfei's love for this guy, almost at the first glance of it, Lin Hongfei fell in love with this big guy with a visual diameter of about 0.5 meters and a length of about 1.8 meters.

Who can believe that such an engine can continue to burst out of 330 kilowatts of power? Even if the traditional piston internal combustion engine can achieve this performance index, it is impossible to work in this power state for a long time, and the engine can not withstand high temperature and high pressure for a long time.

Looking at this big guy, Lin Hongfei's eyes were full of love, and he couldn't help but say to Chapregin, who was blushing with excitement, "I really can't see that such a big guy only weighs so much." ”

Indeed, a metal guy about the same size as an adult strong man of 1.8 meters is only 151.5 kilograms, which can only be said to be very light...... The power of technology is unmatched.

"Actually, you can lose weight even further," Chaprekin pushed his eyes, the excitement on his face still did not dissipate, but obviously, he was much more stable at the moment, "We initially estimate that we can lose another 20 to 30 kilograms, but after designing this engine, the Zaporosh Progressive Machine Building Bureau did not pay attention to it and did not invest much support to improve it, otherwise the performance of this engine would be much better." ”

"Not bad, that's good," Lin Hongfei nodded again and again, in the aviation field, every kilogram of weight is precious, "What is the focus of your next work?" ”

"In the future, we will continue to improve this engine, and on the premise of further reducing fuel consumption and overall weight, we will strive to increase the power by another 50 kilowatts by this time next year, and strive to increase the maximum power of this engine to 430 kilowatts to 450 kilowatts in two years...... We calculated, it's possible. ”

50 kilowatts of power is not much, but only 68 horsepower, but considering that this is something to be done in the case of further reducing fuel consumption and overall weight, this is very remarkable, especially in the aviation field, in the field of reducing fuel consumption, reducing the weight of a few kilograms on the premise of additional 68 horsepower, this is simply a huge surprise: it can make the aircraft fly farther with the same load on the same fuel, and it can also make the aircraft carry more under the same range of the same fuel, Either way, it makes a lot of sense, let alone a continuous improvement to improve performance?

"Okay, just do it!" Lin Hongfei nodded excitedly.

He hadn't thought of anything before, but at this time, when he heard Lao Cha say that he could continue to improve this engine, an idea suddenly popped up, but whether it was feasible Lin Hongfei didn't have much spectrum in his heart, and couldn't help but humbly ask Chapregin, "Lao Cha, do you think there is such a possibility, that is, on the basis of the core technology of this turboprop, just like Pratt & Whitney did, through continuous improvement, two series of engines of various models were designed?"
