It is under such circumstances that after receiving the tender notice from the Air Force Headquarters for air tankers, the Tengfei Group did not choose to be a passerby, but made serious preparations, steadily advanced, and then tore off a piece of meat from the list of air tankers that seemed to be a foregone conclusion.

If this was placed a few years ago, Tengfei Group may have been a bit self-conscious, but in the nineties, Tengfei Group, which has completed industrial upgrading, can directly crush the past with its strength.

The leaders of the Northwest Aviation Plant were in a hurry, and they found the Air Force Headquarters with people, begging grandpa to tell grandma that the Air Force would not cut the list of Bombing 6.

The leaders of the Air Force did not argue with the leaders of the Northwest Aviation Plant, but took out a copy of the Air Force test data of the Oil-15 from his desk: "Look at it, if your Fuel 6 can achieve this indicator, the Air Force will give you the list." ”

The leaders of the Northwest Aviation Plant took a look at it and were immediately dumbfounded.

Length: 36.2 m, height: 10.3 m, wingspan: 34.6 m

The maximum take-off weight is 65.8 tons, the empty weight is 25.1 tons, the fuel carrying capacity is 17.2 tons, and the maximum load is 23.5 tons.

Under normal circumstances, the transport of oil-15 can carry about 30 tons of aviation fuel, providing about 18 tons of fuel to all kinds of aircraft, at this time the transport of oil-15 is not only an air tanker, the spare part of its interior can also be transformed into a temporary command post, relying on the perfect electronic navigation equipment of the oil-15 to become the command center in the air or the relay guidance of all kinds of communications.

It is even possible to carry other substances and people on other tasks other than in-flight refueling.

In this state, the combat radius of the Oil-15 has reached 2,200 kilometers.

If long-distance air refueling is required, the internal command and communication module can be disassembled, so that an aviation fuel storage tank is added to the internal compartment, and the aviation fuel carrying capacity of the Yun-15 will be close to 40 tons, and on the basis of this 3,000-kilometer combat radius, it can provide up to 22 tons of fuel supply for combat aircraft.

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

For example, combat aircraft need to be refueled in the air from a distance of 4,000 kilometers, otherwise they will not be able to return to their bases.

At this time, the index of transporting \\ oil -15 will be adjusted to a combat radius of 4,000 kilometers, but the replenishment of fuel will drop to 12 tons.

Of course, even if it does not perform in-flight refueling missions, the Y-15 is still a medium-sized transport aircraft with excellent performance, with an internal cargo compartment of 12.7 meters long, 3.4 meters wide and 2.8 meters high.

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

Not only that, the large volume can also carry the ZB-666 "air pickup" and ZB-MAK helicopters produced by Tengfei Group, and even the S-70 "Black Hawk" helicopter equipped by the army aviation unit can be easily stuffed into the large cabin of the transport\\oil-15 after removing the main and auxiliary propellers.

In addition to equipment, the Y-15 can carry 80 heavily armed soldiers or 66 paratroopers, and even 36 stretchers can be fixed if necessary to serve as a transport aircraft for the wounded.

In other words, in addition to air refueling, the Y-15 is also a good hand in transport aircraft, and it really brings the multi-energy of one aircraft to the extreme.

On the other hand, the H-6 looks like it was modified from the H-6, but in fact, the internal equipment and operation mechanism are very different from the H-6, except for a shell, it has long been insulated from the H-6, that is to say, when the H-6 does not perform the task of refueling in the air, it can only nest in the base, and it cannot do its old job at all, and throw bombs on other people's heads.

In such a comparison, the bombing 6 and the transport of oil-15 instantly superior judgment, transport of oil-15 can be used as a pure transport aircraft when not undertaking air refueling, enhance the strategic mobility and forward deployment capabilities of the troops, when air refueling is required, the installation of internal aviation fuel tank module and air refueling device can fly into the sky, happily to various aircraft as a nurse.

As a result, the transport of oil-15 does not know how to throw off the oil 6 in terms of mission flexibility and operating costs.

After all, the demand for air refueling in the domestic air force at this time is not high, and it will take several years for the third-generation aircraft fleet to expand and the initial results of offensive and defensive operations.

What's more, the performance of the transport-15 does not have to be 6 poor, the maximum take-off weight is 65.8 tons, the maximum fuel load is 37 tons, and it can be supplied with 22 tons of fuel.

The maximum take-off weight of the bombing oil 6 is 78 tons, and the maximum fuel load is also 37 tons, but it can only provide 18.5 tons of fuel supply.

The take-off weight is 10 tons larger than the transport \\ oil -15, not to mention, the fuel load is the same, the maximum fuel supply is less than the transport \\ oil -15, no matter what, from the key indicators of air refueling alone, the bombing 6 is really a little too much to say.

But this is not where several leaders of the Northwest Aviation Plant feel desperate, the multi-mission ability is poor, the increase is enough, the task flexibility is not good, why is it difficult to tackle key problems in this area?

After all, they are a large manufacturer of classic aircraft such as Y-7, Y-8, H-6, FB-7, etc., but it is a matter of concept, and Northwest Airlines lacks the courage to change its thinking?

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

Yes, an important reason why the leaders of the Northwest Airlines Plant could not mention the competition with the Ascendas Group was the aero engine.

Why does the bombing oil 6 carry 37 tons of fuel, but it can only provide a maximum of 18.5 tons of supply fuel, is it that the bombing oil 6 does not want to give more?

It's not that the turbojet 8 engine equipped with the fuel 6 is not powerful, in addition to the thrust is a little larger, it is a mess in terms of maintainability and fuel economy, especially in fuel economy, it can be called an oil tiger, if there is not enough fuel in the fuel tank, it is difficult to say whether the fuel 6 can come back with all the full shadow.

In contrast, although the Y-15 is equipped with four engines, which looks twice as much as the H-6, the comprehensive fuel performance of the four engines is much better than that of the H-6, and according to the comprehensive test results of the Air Force, the comprehensive fuel consumption of the four engines of the Y-15 is 36.4% lower than that of the H-6 of the two engines.

This is still obtained in the case of the Yun-15 at a maximum speed of 842 km/h, if the cruising speed of 720 km/h, at an altitude of 11,000 meters, the comprehensive fuel consumption of the Yun-15 will be further reduced, and can even reach half of the bombing 6.

There is no way, the latest WD-52ML turbofan engine launched by Tengfei Group is focusing on fuel economy, how to compare with the Northwest Airlines Plant, which has been gnawing at the old model for twenty or thirty years!
