    Products produced by Tengfei must be high-quality products.

    The Air Private Car 2 solution is no exception. Based on the original modular design of the Yun-17, Ascendas Group added two extended cabin sections to the basic model of the Yun-17, increasing the total length by 5 meters to 38.82 meters. This earned it  Provides more space for modification.

    Based on this, Ascendas Group has made various optimizations to make Yun 18 have a length of 22.3 meters and a width of 7.1 meters.  A huge warehouse with a height of 6.8 meters and a total volume of 1076.6 cubic meters.

    Don¡¯t underestimate this warehouse. The main transport aircraft used by the former Soviet Union and current Russia, the An-124 strategic transport aircraft, has a cargo warehouse volume of 1,148 cubic meters.

    It is only less than 100 cubic meters more than the Y18. This shows how strong the Y18 is in transporting large-sized cargo.

    In fact, this is indeed the case. The existing equipment, equipment under development and even pre-development equipment equipped by the Second Artillery Force, such as missile bodies, fuel storage tanks, instrument cabins, loaders and other key large-scale equipment, can be transported to almost all the 18  Easy to load.

    Especially for the loading of the Dongfeng 5 improved large-size missile casing, this big thing with a diameter of 3.35 meters and a length of 20 meters is difficult to transport whether by train or heavy truck, so that in the past, only  Can be shipped in sections.

    Even using a special transport aircraft like the Y-16 is not possible, because the length of the cargo compartment of the Y-16 is only 20.56 meters. Although the large-size missile body of the improved Dongfeng 5 can be loaded into the cargo compartment of the Y-16, there is no fixed cable.  There is no way to load the mooring space at all, so it can only be cut and loaded according to the 18-meter specification.

    It¡¯s just that this will inevitably lead to a lot more connection points during final assembly, which not only affects the safety of the missile, but also increases the total amount of unnecessary structure.

    The emergence of the Yun-18 has solved this problem very well. Not only can the 20-meter-long big thing be easily loaded in, but it can also be transported and flown away together with other accessories such as internal fuel tanks, control equipment, and navigation equipment.

    After all, the maximum load capacity of the Yun-18 has reached 33 tons, which is 11 tons higher than the 22 tons of the previous generation Yun-16. Therefore, when performing transportation tasks, it can carry products with a higher degree of completion, thus improving production efficiency.

    The cargo load alone has reached 33 tons. The Yun-18 itself is naturally a heavyweight, with an empty weight of 38 tons and a maximum take-off weight of 105 tons.

    It has become the largest aircraft developed and produced by Ascendas Group so far.

    A few years ago, Ascendas Group would not have dared to touch the threshold level of this large aircraft, let alone 100 tons, even if it exceeded 80 tons.

    There is no way. In fact, the Ascendas Group has said that many of the key production and manufacturing equipment of large aircrafts are also blank in China. Even if they want to do it, there is no place to do it. They can only find ways to reduce the total structural weight as much as possible and keep it below 80 tons.  .

    ¡° However, all this, along with a batch of professional equipment for large aircraft production provided by Russia¡¯s Tupolev Design Bureau, can be regarded as a complete solution to Ascendas Group¡¯s problems.

    Although the original intention of the Russians was to jointly produce the Tu-204 passenger aircraft and take this opportunity to expand Russia's market share in the field of civil aviation passenger aircraft, this plan of Russia was blocked by aviation giants such as Boeing and Airbus. Fortunately, the Tu-204 passenger aircraft was  Polev has delivered the key equipment. Although it is a pity that they cannot jointly produce the Tu-204, it gives Ascendas Group the opportunity to get involved in the 100-ton target, which was previously unthinkable.

    So the aerospace engineers of Ascendas Group, who used to be so scrupulous in the past, completely let themselves go this time. If it weren't for the restrictions on the Second Artillery, let alone the 100-ton class, even the 150-ton class could be saved for you.

    There is no way, who made Ascendas Group¡¯s aero engines ready for this day long ago.

    WD -60ml -22 Dahan Road Bybi engine.

    It was once intended to be the main power source for the domestically produced Tu-204 passenger aircraft. Although the Tu-204 project was stillborn, the research and development of this large-bypass-ratio turbofan engine with a maximum thrust of 12.5 tons has not stopped and has always been under Zhuang Jianye's control.  Under the promotion of the company, it has been gradually improved and started to be put into small batch production in recent years.

    Therefore, the aviation designers of Ascendas Group do not have the "power phobia" of other domestic colleagues. The wd-60ml-22 large bypass ratio turbofan engine is pitifully waiting for them to squeeze, ravage and claim.  .

    Coupled with the unrestricted access to high-end aviation materials, another major segment of Ascendas Group, these aerospace engineers simply cannot be too happy.

    ?????????????????????????????????????????????????????????????????????????????????????????????????????????????: It is said to be a modification on the basis of the Y-17, but in fact it is to build a new aircraft.

    So the Yun-17nb, which was named by Zhuang Jianye himself, was unusable and had to be priced at the same price, so it became the Yun-18.

    The subsequent ground static test, complete aircraft structural test, test flight, evaluation and other aspects took more than three years. Naturally, there were twists and turns during this period, such as the aircraftThe engine may occasionally experience insufficient thrust during mid-air tremor or plateau takeoff.

    Fortunately, Ascendas Group has solved all the problems one by one, so that it can build such an excellent special transport aircraft in a short time.

    Of course, excellent performance does not mean that the Yun 18 is not certain. Almost like other products produced by the Ascendas Group, the biggest disadvantage of the Yun 18 is that it is expensive.

    The unit price of 560 million yuan directly broke the price record of domestic aircraft.

    So much so that when the leaders of the Second Artillery Corps received the final quotation, they almost went crazy collectively. One aircraft was 560 million yuan, and 6 aircraft was 3.36 billion yuan.

    3.36 billion, how many missiles can you buy?

    But in the end, the Second Artillery Corps gritted its teeth and bought 6 aircraft. It had no choice but to make the Y-18 the only platform that can carry out the Dongfeng 5 improved full-size segmented and integral transportation.

    Not only that, in order to increase the reliability of the missile and reduce the connection of segments, the Dongfeng 4x missile segments of the Second Artillery's next-generation road-based mobile strategic missile also need to be transported by 18.

    Even if the land-based missiles are not used, the more demanding sea-based Julang 1 and Julang 2 will also need to transport 18 to better solve their own transportation problems.

    Because of this, even if the Yun-18 breaks the price record of domestic aviation products and directly pushes the upper limit to 500 million, due to the huge role that the Yun-18 will play in the future, the Second Artillery Corps still spends a lot of money and buys it out.

    From this aspect, the heads of the Second Artillery are much more generous than the heads of the headquarters.

    We even agreed to buy the second artillery piece, and the Air Force must show some interest. However, the head of the headquarters said: "This thing is not practical."

    This completely gave up the idea of ??Ascendas Group expanding sales.

    Zhuang Jianye, who went to the headquarters for promotion at that time, had exactly the same expression as the heavy-armed force cadres at the airstrip at this moment. They were both surprised and confused. However, unlike Zhuang Jianye, the heavy-armed force cadres were after all people within the army and were listening.  After hearing Xue Weidong's comment on the impracticality of the Yun-18, he was a little surprised and nodded unconsciously: "That's true. If nothing else, the load capacity of 33 tons is a bit embarrassing. The Army's Type 88 tank is all important in combat.  The carrying capacity of 38 tons or at least 40 tons is barely enough, so alas except for a few imported IL-76s, we don't have such a transport aircraft yet."

    "Who said no?"

    Hearing this, Xue Weidong raised the corner of his mouth slightly and asked a meaningful question. As a result, when he finished speaking, the sound of an engine roared from the sky, and immediately a four-engine Universiade with a gray sky appeared in people's sight.  middle.
