Chapter 475

It's no wonder that song Changzheng was like this. The average fuel consumption rate of the turboprop engines on an-26 and yun-8 currently equipped by the navy is more than 0.453 kgkwh.

This is still the normal level of the two aircraft under the economic speed. If it is a special task to run with the maximum throttle regardless of fuel consumption, the fuel consumption rate will be higher.

However, none of the turboprop engines powered by Tengfei has a fuel consumption rate of more than 0.308 kgkwh, which is 0.14 kgkwh lower than that of the turboprop engines equipped on an-26 and yun-8.

That's more than 30 percent.

We should know that the fuel consumption rate of the engine is an important index of fuel saving. The lower the value is, the smaller the unit fuel consumption will be. It is very important to reduce the fuel consumption rate by 30%, which means that under the condition of equal fuel, the flight platform with turboprop engine powered by take-off aviation will have more than 30% more range.

And this is only a single station. If there are two or four engines, the data will be doubled.

Take the Navy's an-26 as an example. The average range is about 1600 km. If the fuel consumption rate of each engine is reduced by 30%, two engines will be 60%. In the case of inconvenient fuel tanks, the range of an-26 will be increased from 1600 km to 2560 km after the installation of turboprop engines powered by take-off aviation.

2560 kilometers, or 1200 kilometers in half, is enough to take off from the East China coastal airport to carry out reconnaissance and patrol missions in the Yellow Sea or the East China Sea.

Even in the vast South China Sea, there is great potential. You should know that the data calculated by the appliance is the average range, in other words, the range data of an-26 oil load reaching a certain degree. If the equipment is reasonably configured according to the task, the range will be further improved.

If we cooperate with the field airport to be built in Yongxing Island, cruising the South China Sea with the dual engine light an-26 is really not something we can only dream about.

For the Navy, it's not just like a peerless master who has been hit by a soft rib. He really doesn't have any resistance. He wants to go back with a turboprop engine powered by take-off aviation and replace his own an-26.

There's no way. Now the navy is very short of special platforms on the sea. If it hadn't, it would not have been possible for the navy to use them to refit them into maritime patrol planes as soon as they were finalized.

However, the overall performance of yun-8 maritime patrol aircraft can not be said to basically meet the needs of the Navy. On the one hand, the number is too small, and on the other hand, the operating cost is too high. After all, it is the refitting of medium-sized transport aircraft platform, the four engine structure, and the cost of fuel used once is a big number.

Therefore, the Navy urgently needs a low-cost, efficient and relatively low-cost light aviation platform as a supplement to the yun-8 maritime patrol aircraft to perform more frequent maritime patrol, ship formation relay communication, anti-ship missile relay guidance, and even preliminary maritime early warning and other support combat tasks.

It is reasonable to say that an-26 of naval equipment or yun-7, which has just been finalized every two years, is the best choice in this respect. Unfortunately, the carrying capacity and space of the two models are both good. However, the voyage is a short board, which is the largest voyage of more than 1000 kilometers. After flying from the airport to the sea for a while, I haven't seen clearly what's going on on the sea. I find that the speed in the fuel tank is not enough to return, So I can only turn back in a hurry.

Of course, the navy has not thought of other ways, such as the unmanned reconnaissance-8 "Plath" UAV system equipped by the air force surveying and mapping brigade.

The problem is that the uav-8 "Plath" system can turn any way on the land, and it is a bit like a fly without a head when it comes to the sea, with all kinds of failures.

The reason is very simple. The core of the UAV system is remote control and information transmission based on communication satellites. If it is in the United States, all this is not a problem, because there are dozens of optical military communication satellites in the United States, and there are hundreds of commercial communication satellites, covering the whole world. Therefore, the performance of their bullet a platform is very good General, but it is the only UAV in the world that can fly around the world.

The domestic gap in this respect is not generally large. Only a few Dongfanghong series communication satellites, together with a few leased international communication satellites, will be able to cover the land, but also the sea.

As a result, the Navy prefers a light, long-range, multi-purpose flight platform.

It's a pity that the domestic similar platforms can't meet the requirements of the Navy, and the foreign ones are too expensive, so the navy has no choice but to drag this matter down.

I thought it would take a turn for the better in the 1990s, but I didn't expect to see the hope when I visited Tengfei aviation power. The turboprop engine that can reduce fuel consumption by 30% is just pie in the sky.

The Navy's 15 an-26s don't need anything. They can increase their range by more than 50% if they are directly equipped with D-series turboprop engines powered by take-off aviation. Song Changzheng and Li Fang feel like they won the five million lottery in the future. The more information they have, the more happy they are.It doesn't matter what advanced materials or 5000 km advanced light transport platforms are. It's the most urgent thing to solve the Navy's dilemma. So before he finished watching, Li Fang looked up excitedly and asked Qian Qiang, "Qian Gong, can you give me a copy of the specific information about the three turboprop engines you've made? I want to go to the capital immediately and think about the Navy General Manager The leaders of the Ministry will make a special report. "

Then he turned to look at Zhuang Jianye: "Mr. Zhuang, since you can produce the shipment 6, the aircraft manufacturing technology should be very good. If you can, I hope you can send some experts to the navy to inspect the xiaan-26 model. If you can, the navy is very willing to replace your D-series engine."

This is to make Tengfei Airlines refit Navy an-26?

Zhuang Jianye's head flashed this sentence, but before he could answer, song Changzheng added: "by the way, the quotations of several turboprop engines have been quoted. Oh, by the way, the quotations of d-50 are also quoted together, so that the superior leaders can make an overall plan."

"Er..." Zhuang Jianye hesitated for a moment. As a result, director Zhao next to him once again took the lead and said, "carbon fiber reinforced aluminum matrix composites, you can form a detailed report here. Oh, other materials should also be made separately, and strive to report it next week."

After that, he thought it was wrong. Finally, he frowned and added, "forget it, you can come to Beijing next week and report to the head of the headquarters with me."
