Take Off My Aviation Era

"Don't be nonsense, I want to go home savagely at night to find your wife savagely, it is close to the maximum power, give me a little bit of stability."

As soon as the pilot's words were finished, Song Changzheng went back unceremoniously. Although Qian Qiang, who was following the test flight, was used to it, he still had the urge to cover his face and pretend not to recognize the old man.

Naval technical expert, deputy director of the Aviation Equipment Technology Research Institute, usually approachable, always smiling Song Changzheng, entering the army just like changing the individual, tearing off the mask of the gentleman, and following a mountain top Like the head of a horse, as long as it is not a formal occasion, it is commonplace for me to be long and short.

All kinds of fragrant mouths, small meaty jokes, and a loud and loud voice are the real daily life of Lao Song.

That’s why Qian Qiang always thinks every time he sees Song Changzheng plunge into the pile of officers and soldiers, holding a big tea jar full of liquor, and even swearing and arguing with his subordinates all kinds of madness, just like this. How did you graduate from the Kazakhstan military industry.

"It can really be mentioned above. I think the engine has plenty of spare power. Unlike the ai-24t of the Soviet Union, although it has a maximum horsepower of 2820, it will only blow when taking off under full fuel and full load. When flying, the horsepower attenuates a lot at 2500 horsepower, and it doesn't make much effort."

Qian Qiang was still thinking about it. The pilot’s words came through the radio again. Song Changzheng frowned and thought about it, but he didn’t dare to make any decisions, because the manual for the d-46ml turboprop engine provided by Ascendas Aviation Power clearly stated. The maximum power marked is 2051 kilowatts, which is 2788 horsepower.

From the specific data point of view, it is not as good as the original Soviet ai-24t turboprop engine on the An-26, because the power of the Soviet product is 2074 kilowatts, which is equivalent to 2820 horsepower.

It seems to be slightly better than the d-46ml turboprop engine.

But in fact, it is not easy for the ai-24t turboprop engine to reach the maximum power. Unless you risk the engine life degradation and fuel consumption regardless of the cost, the maximum power of the ai-24t turboprop can only be maintained for a few minutes. , Because the time is long, the oil carried on the plane will not be enough, which will easily cause the bearing in the engine to friction and fall off, leading to aerial parking.

Therefore, unless it is full of fuel and full load, in order to speed up the takeoff, the pilot will increase the throttle to boost the maximum power of the ai-24t turboprop engine to assist the takeoff. Under normal circumstances, the takeoff power of the An-26 is about 2500 horsepower.

In such a calculation, the d-46ml turboprop engine is actually higher than the original Soviet ai-24t turboprop engine.

Because the d-46ml turboprop engine is said to be 2788 horsepower, that is, 2788 horsepower, which will not be hit at the slightest discount, so from the perspective of the stability of power output, the d-46ml turboprop engine fully meets the general routine of An-26 demand.

As for full fuel and full load, although the maximum horsepower output is not as large as the ai-24t turboprop engine, the weight of a single d-46ml is only 500 kg, which is 100 kg lower than the 600 kg of ai-24t. A series of optimizations have been made for lubricating oil, oil pipeline rate, and deicing system. Coupled with a six-blade variable-pitch composite propeller, the overall structure is more compact, lighter and more efficient than ai-24t.

Because of this, although the maximum power is slightly inferior, it is not detectable in practical applications. On the contrary, I feel that it is much better than the past ai-24t in some aspects.

Because the power output of the d-46ml is more stable and smooth, especially the new six-blade variable pitch propeller made of composite materials, the lift of the An-26 can be described as immediate improvement, so even after the replacement of the An-26 Take off with a full load of oil, the d-46ml is effortless, and there is even more power.

In this regard, the pilot flying in the sky can understand better than anyone else. It is already 2612 horsepower, but the engine is in very good condition. In this case, the pilot is like a racer driving a sports car, and I really want to experience a strong push. Back feeling.

However, the pilot wanted to be refreshed, but Song Changzheng was very cautious. Don't look at him being careless with the officers and soldiers below, like a ringleader, it was just a small way to integrate with the officers and soldiers.

In fact, Song Changzheng has a very clear head. If otherwise, how could he become a member of the Kazakhstan military industry and how could he become an equipment expert for the naval aviation force step by step, so he is still a little bit resistant to how much pilots want to try to cruise with high horsepower. .

After all, the reissued An-26 showed excellent performance during the test flight during this period. Thanks to the technical exploration of Ascendas Aviation Power in terms of fuel saving, the fuel consumption rate of d-46ml reached 0.294 kg kilowatt per hour. Compared with the original Soviet ai-24t, the fuel consumption rate is reduced by 35%.

Coupled with the more efficient six-blade composite variable-pitch propeller, fuel economy is further improved, and the overall fuel consumption rate is reduced by 46.27% compared to before the replacement.

In other words, with the overall structure of the An-26 inconvenient, the maximum range increased by 46.27% by simply replacing the engine, from the original 2500 kilometers to the current 3656 kilometers. If an additional fuel tank is added inside the body, The voyage can be further increased to four thousand kilometers.

Today, the South China Sea, the most extensive sea frontier, is only 2,000 kilometers long from north to south. With a range of 4,000 kilometers, An-26 can fully cruise from south to north in the South China Sea.

This is too important for the navy that lacks air support ~www.readwn.com~ and precious enough.

Because the navy can carry out this type of long-distance flight aircraft, except for the Y-8 maritime patrol aircraft, which is the H-6 bomber. The problem is that the two types of aircraft are not only small in number, but also have to frequently switch defenses between the three major fleets. Regardless of long-term stationing in one direction, the use cost is still extremely high.

It is the limitations of the Y-8 maritime patrol aircraft and the H-6 bomber that highlight the preciousness of the d-46ml An-26.

Because of this, when the Naval Headquarters learned about the flight test of the An-26 after the reissue, it immediately requested Song Changzheng to complete the flight test with high quality and quantity, and strive to formally equip the troops for adaptability training before the end of the year.

Others do not know the urgency of the navy headquarters. How could Song Changzheng, the leader of the test flight, be unclear, but because of this, he cannot be as blind as others. If something goes wrong and affects the planning of the headquarters, it is a sin. It's big.

So frowning for a long time, but still undecided, finally turned his head to look at Qian Qiang, and asked, "How long can your d-46ml last at maximum power?"

"At least 1,800 hours." Qian Qiang answered without hesitation.
