    It was under such circumstances that after receiving the bidding notice for aerial tankers from the Air Force Headquarters, Ascendas Group did not choose to be a passer-by. Instead, it prepared carefully, steadily advanced, and then placed the order for aerial tankers that seemed to be a foregone conclusion.  Tear off a piece of meat.

    A few years ago, Ascendas Group might have been a little overconfident, but in the 1990s, Ascendas Group, which had completed industrial upgrading, could use its strength to directly crush them.

    The Northwest Aviation Factory, which thought it was a sure bet, was actually caught off guard by the Ascendas Group. Seeing that their orders for the H-6 were about to be cut off, the leaders of the Northwest Aviation Factory became anxious and led their people to the Air Force Headquarters.  I beg my grandpa and grandma to hope that the Air Force will never cut the H-6 order.

    The leader of the Air Force did not argue with the leader of the Northwest Aviation Factory. Instead, he took out a copy of the Air Force test data of the H-15 from his desk: "Let's take a look. If your H-6 can achieve this indicator, the Air Force's  I¡¯ll give you the list.¡±

    When the leaders of the Northwest Aviation Factory took it over and took a look, they were immediately dumbfounded.

    Aircraft length: 36.2 meters; height: 10.3 meters; wingspan: 34.6 meters

    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 Yunyou-15 can carry about 30 tons of aviation fuel, and provide about 18 tons of fuel to various types of aircraft. At this time, the Yunyou-15 is not only an aerial tanker, but its internal spare parts are also  It can be transformed into a temporary command post, and rely on the Yuanyou-15's complete electronic navigation equipment to become an air command center or a relay guide for various communications.

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

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

    If long-distance aerial refueling is required, the internal command and communication module of the Yunyou-15 can be disassembled to add an aviation fuel storage tank to the internal compartment. In this state, the aviation fuel carrying capacity of the Yuanyou-15 will be close to 40 tons.  For this reason, based on a combat radius of 3,000 kilometers, it can provide up to 22 tons of fuel supply for combat aircraft.

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

    For example, combat aircraft need to be refueled in the air 4,000 kilometers away, otherwise they will not be able to return to their base.

    At this time, the oil transportation-15 indicator will be adjusted to a combat radius of 4,000 kilometers, but the fuel supply will drop to 12 tons.

    Of course, even if it does not perform aerial refueling missions, the Yunyou-15 is still a medium-sized transport aircraft with excellent performance. Its internal cargo compartment 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 can also 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 Ascendas Group, and even the S-70 "Black Hawk" helicopter equipped by the Army Aviation Force with the main and auxiliary propellers removed.  It can be easily stuffed into the spacious cabin of the Oil Transport-15.

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

    In other words, in addition to aerial refueling, the Yunyou-15 is also a good player as a transport aircraft. It really maximizes the versatility of one aircraft.

    On the other hand, the H-6 seems to be modified from the H-6. In fact, the internal equipment and operating mechanism are very different from the H-6. Except for a shell, it has long been insulated from the H-6. In other words, when the H-6  When Oil 6 is not performing aerial refueling missions, it can only stay at the base. It cannot do its job at all, throwing bombs on other people's heads.

    Such a comparison makes the H-6 and the Yanyou-15 instantly distinguishable. When the Yanyou-15 is not responsible for aerial refueling, it can be used as a pure transport aircraft to enhance the strategic mobility and forward deployment capabilities of the troops. When aerial refueling is needed,  , with the internal aviation fuel tank module and aerial refueling device installed, it can fly into the sky and happily serve as a nanny for various aircraft.

    ¡°As a result, the Yunyou-15 is way ahead of the H-6 in terms of mission flexibility and operating costs.

    After all, the domestic air force¡¯s demand for aerial refueling is not high at this time. It will take several years until the third-generation aircraft fleet expands and the offensive and defensive operations begin to take effect. In this transitional stage, professional aerial refueling  The machine is obviously not as cost-effective as the multi-tasking machine with multiple functions.

    What's more, the performance of the Tank-15 is not even worse than the fuel bombing. The maximum take-off weight is 65.8 tons, the maximum fuel load is 37 tons, and it can provide 22 tons of fuel supply.

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

      Not to mention that the take-off weight is 10 tons larger than that of the Tank-15, even if the fuel capacity is the same, the maximum fuel supply is actually smaller than that of the Tank-15. Regardless of other factors, looking at this key indicator of aerial refueling, the bomb  Oil 6 is really a bit unreasonable.

    "But this is not where several leaders of the Northwest Aviation Plant feel despair. The multi-tasking capability is poor and they can just increase it. The task flexibility is not good, so why is it difficult to tackle this problem?

    These are nothing to Northwest Aviation Factory. After all, they are a major manufacturer of classic aircraft such as Y-7, Y-8, H-6, FB-7, etc. It is just a matter of philosophy. Northwest Aviation Factory lacks a change of thinking.  Courage?

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

    Yes, the important reason why the leaders of Northwest Aviation Factory cannot mention the competition with Ascendas Group is the aviation engine.

    Why does Hongyou 6 carry 37 tons of fuel, but can only provide a maximum of 18.5 tons of fuel supply? Does Hongyou 6 not want to provide more?

    It¡¯s not that the turbojet 8 engine equipped with the Hongyou 6 is not powerful. Except for the larger thrust, it is a mess in terms of maintainability and fuel economy. Especially in terms of fuel economy, it can be called a fuel tiger. If there is no oil in the fuel tank,  With enough fuel, it's hard to say whether Hongyou 6 can return in full glory.

    In comparison, although the Yunyou-15 is equipped with four engines, which seems to be twice as many as the Hongyou 6, the comprehensive fuel performance of the four engines is much better than the turbojet 8 of the Hongyou 6.  , according to comprehensive test results of the Air Force, the comprehensive fuel consumption of the four engines of the Yunyou-15 is 36.4% lower than that of the two-engine H-6.

    This is achieved when the Yunyou-15 cruises at a maximum speed of 842 kilometers per hour. If the cruising speed is 720 kilometers per hour at an altitude of 11,000 meters, the comprehensive fuel consumption of the Yunyou-15 will be further reduced, and it can even reach  Half of the Hyou 6.

    No way, the latest wd-52ml turbofan engine launched by Ascendas Group focuses on fuel economy. How can it compare with Northwest Aviation Factory, which has been relying on old models for 20 to 30 years?
