Chapter 825

Under such circumstances, Tengfei group, after receiving the bidding notice from the air force headquarters, did not choose to be a passer-by. Instead, it made serious preparations and made steady progress, and then tore a piece of meat off the list of air tankers that seemed to be a foregone conclusion.

A few years ago, Tengfei group might have been a bit over confident. However, in the 1990s, Tengfei group, which has completed the industrial upgrading, can completely crush it with its strength.

The northwest aviation factory, which was supposed to be safe, was caught off guard by Tengfei group. Seeing that the order of Hongyou 6 was about to be cut off, the leaders of northwest aviation factory were in a hurry. They took people to the air force headquarters and asked their grandparents not to cut the list of Hongyou 6.

Instead of arguing with the leader of Northwest Airlines, the air force leader took out a copy of the air force test data of oil transportation-15 from his desk: "look, if your bomb oil 6 can achieve this target, the air force list will be given to you."

The leaders of Northwest Airlines took it over and looked at it. They were immediately dumbfounded.

Aircraft length: 36.2m; height: 10.3M; wingspan: 34.6m

maximum takeoff weight: 65.8t, empty weight: 25.1t, fuel carrying capacity: 17.2t, maximum load: 23.5t.

Under normal circumstances, yunyou-15 can carry about 30 tons of aviation fuel, and provide about 18 tons of fuel to all kinds of aircraft. At this time, yunyou-15 is not only an air tanker, but also its spare part can be transformed into a temporary command post. Relying on the perfect electronic navigation equipment of yunyou-15, it can become the command center in the air or the relay of all kinds of communication Guide.

It can even carry other materials and personnel to perform other tasks other than aerial refueling.

In this state, the operational radius of oil transportation-15 has reached 2200km.

If long-distance aerial refueling is required, the internal command and communication module of the oil transportation-15 can be disassembled, so that an aviation fuel storage tank can be added in the internal cabin. Under this condition, the aviation fuel carrying capacity of the oil transportation-15 will be close to 40 tons. On the basis of this 3000 km combat radius, the maximum fuel supply for combat aircraft can be 22 tons.

Of course, this value is not constant, but adjusted according to the specific situation of the task.

For example, combat aircraft need to refuel in the air 4000 kilometers away, or they will not be able to return to the base.

At this time, the target of oil transportation-15 will be adjusted to 4000 km, but the fuel supply will be reduced to 12 tons.

Of course, even if we don't carry out the aerial refueling mission, yunyou-15 is still a medium-sized transport aircraft with excellent performance. Its internal cargo warehouse is 12.7 meters long, 3.4 meters wide and 2.8 meters high.

This volume can not only accommodate most of the army's light combat vehicles, but also easily carry a type 63 amphibious tank for rapid forward deployment.

Not only that, the super large volume can also carry zb-666 "air pickup" and zb-mak helicopters produced by Tengfei group, and even S-70 "Black Hawk" helicopter equipped by land and air force can be easily packed into the 15 wide engine room after removing the main and auxiliary propellers.

In addition to equipment, the oil transportation-15 can also carry 80 fully armed soldiers or 66 paratroopers, and even fix 36 stretchers when necessary as a transport aircraft for the wounded.

In other words, in addition to refueling in the air, yunyou-15 is also a good hand in transport aircraft. It really brings one aircraft into full play.

On the other hand, it seems that Hohhot 6 was refitted from Hohhot 6. In fact, the internal equipment and operation mechanism are quite different from Hohhot 6. Apart from a shell, Hohhot 6 has long been insulated from Hohhot 6. That is to say, when Hohhot 6 does not carry out the air refueling mission, it can only stay in the base, and it can't handle its old business and throw bombs at other people's heads.

In such a contrast, Hongyou 6 and yunyou-15 can make a decision instantly. When yunyou-15 does not undertake aerial refueling, it can be used as a pure transport aircraft to enhance the army's strategic mobility and forward deployment capability. When aerial refueling is needed, it can fly into the sky with the internal aviation fuel tank module and aerial refueling device, and happily serve as a nurse for various aircraft.

As a result, yunyou-15 does not know how many blocks to dump in terms of mission flexibility and operation cost.

After all, the domestic air force's demand for aerial refueling is not high at this time. It will take several years for the third generation aircraft fleet to expand and for the offensive and defensive operations to show initial results. In this transitional period, it is obvious that professional aerial refueling aircraft are not cost-effective to have a multi-functional and multi task aircraft.

What's more, the performance of yunyou-15 does not have to be worse than 6 tons. The maximum takeoff weight is 65.8 tons, and the maximum fuel load is 37 tons. It can supply 22 tons of fuel.

The maximum takeoff weight of Hongyou 6 is 78 tons, and the maximum fuel load is 37 tons, but it can only provide 18.5 tons of fuel supply.

The take-off weight is 10 tons larger than that of the fuel carrying capacity-15. Not to mention that the fuel carrying capacity is the same, the largest fuel supply is smaller than that of the fuel carrying capacity-15. No matter what else, judging from this key index of air refueling, the fuel carrying capacity-6 is somewhat unreasonable.However, this is not the place where several leaders of Northwest Airlines feel hopeless. Their multi task ability is poor, so it is necessary to increase the number of tasks. The task flexibility is not good. What's the difficulty in tackling key problems in this respect?

These are nothing to Northwest Airlines. After all, they are big manufacturers of classic aircraft such as yun-7, yun-8, hong-6 and fb-7. It's just a matter of concept. Does Northwest Airlines lack the courage to change its mind?

There is no shortage, but they lack a heart enough to make their aircraft surging.

Yes, the important reason why the leaders of northwest aviation plant can't mention to compete with Tengfei group is aeroengine.

Why does Hongyou 6 carry 37 tons of fuel, but it can only provide 18.5 tons of refuel at most? Is it that Hongyou 6 doesn't want to give more?

is in a complete mess of the 6 turbo 8 engines equipped with suck oil. In addition to the larger thrust, it is a mess in maintainability and fuel economy. Especially fuel economy is a tigers. If the fuel tank is not filled with fuel, it is hard to say whether the fuel oil 6 can be fully returned.

In contrast, although yunyou-15 is equipped with four engines, which is twice as much as that of hongyou-6, the comprehensive fuel performance of the four engines is much better than that of the turbojet 8 of hongyou-6. According to the comprehensive test results of the air force, the comprehensive fuel consumption of the four engines of yunyou-15 is 36.4% lower than that of the two engines of hongyou-6.

This is achieved at the maximum speed of 842 kmh. If the cruising speed is 720 kmh and the altitude is 11000 meters, the comprehensive fuel consumption of yunyou-15 will be further reduced, even half of that of hongyou-6.

There's no way. The wd-52ml turbofan engine launched by Tengfei group focuses on fuel economy. How can the Northwest Airlines, which has been working on the old model for 20 or 30 years, compare with it!
