Previous page        Return to Catalog        Next page

    The Air Force saw that it was no longer possible. If it did not control the military expenditure allocation in the next few years, it would not be enough to fill the gap. So it decisively asked Ascendas Group not to spread its stall so big and concentrate on one model.

    result¡­¡­

    The Air Force still has not escaped the law of true fragrance.

    When Ascendas Group came up with four aircraft models based on the advanced light transport platform concept under pressure, the Air Force's previous idea of ??shrinking the defense line and attacking more was completely thrown into the pile of old papers, and Ascendas Group's achievements were directly passed through the headquarters.  Report it to the decision-makers, then apply for a large wave of special funds, and join the Ascendas Group without hesitation.

    There is no way around it, the four models are really too tempting to put down. Not to mention the Air Force, even the Navy are eager to try them out after learning about the situation. As for the major domestic airlines, they are even more eager to learn about the situation.

    Why, it¡¯s very simple, what Ascendas Group has produced is excellent enough.

    The four models include six Y-15s and four Y-15plus that have been equipped to an aviation group of the Airborne Forces. There are also two jet aircraft. The internal code names of Ascendas Group are Haidong Qing b and Haidong Qing bplus.

    Of course, Yun-15 and Yun-15plus are the names of military models after they were equipped with the Air Force. When Ascendas Group launched the advanced light transport platform, the code names of these two models were also called Haidongqing, but compared to the B-type, the Yun-15  The series is type A.

    Type A and Type B together are the most core plan of Ascendas Group in the past five years, and it is also the most far-reaching plan for the future, that is, the "Haidong Qing" plan, which is sublimated from the concept of advanced light transportation platform.

    The plan is divided into three phases.

    The first phase is centered on Haidong Qing A and Haidong Qing a plus, backed by the support of the military and the state. In the process of developing military transport aircraft, the design, development, production and production of light transport platforms with a take-off weight of 25 to 30 tons have been accumulated.  Manufacturing experience.

    The second stage is to perfect the A-type and Aplus and start the development of B-type.

    The final third stage is to complete the mass production of feeder transportation platforms with 70 to 100 seats in the late 1990s and early 20th century, laying the foundation for the development of medium-sized and large-scale transportation platforms in the new century.

    Based on this plan, Ascendas Group¡¯s Haidongqing A-type benchmark customer is aimed at the military, so it adopts a high-wing monoplane and a T-shaped vertical tail layout.

    But the positioning is not limited to the military. For example, the Y-15 is equipped with airborne troops. Ascendas Group actually positions it as a multi-functional dual-use platform for both military and civilian use.

    Because the interior has been transformed into a passenger transport aircraft, civil aviation navigation and communication equipment has been installed, and facilities such as luggage storage, toilets and kitchens have been added. It is now a typical 46-seat regional passenger aircraft.

    With a design range of 3,500 kilometers, it can immediately perform air transportation services in Tibetan plateau and border areas, and can also perform medium-range passenger transportation services in inland provinces.

    Based on this, Ascendas Group¡¯s plan is to develop it into a professional turboprop transportation platform. When the 3,500 to 4,200 kW class wd-50j turboprop engine is fully mature, Haidong Qing A will be equipped with a higher power engine.  With further improvements and upgrades, its take-off weight will reach 35 tons, making it an excellent regional turboprop aircraft with a range of 4,500 kilometers and a passenger capacity of 76.

    In terms of military use, the deeply upgraded Haidong Qing A will be more flexible and have better performance.

    Compared with Haidongqing's dual-use military and civilian models, Haidongqing Aplus is a military model through and through. Regardless of the size of the cargo compartment, take-off distance or loading items, it is completely designed according to the combat needs of the army, with almost no civilian use.  aspects of things.

    Therefore, Haidong Qing Aplus will be the signature and foundation of Ascendas Group's military transport aircraft in the future. When the wd-50j turboprop engine with the same core engine and the WD-50s large bypass ratio turbofan engine with a thrust of 6.5 tons is put into production, Haidong Qing will  The maximum take-off weight of aplus will be close to 40 tons.

    By then, the upgraded load capacity of the Haidong Qing Aplus will reach about 18 tons, and the further improved cargo warehouse will be able to accommodate a Type 63 tank or an "air pickup" helicopter.

    This will greatly expand the combat flexibility and mission requirements of the troops. In addition, the combat capabilities of the airborne troops, southern amphibious forces and plateau mountain troops will be greatly enhanced.

    Compared with the turboprops and turbofans of the Haidong Qing A type, which have both military and civilian uses, the Haidong Qing B is much simpler at the beginning of the second phase. Its main purpose is to target the growing regional air transport market at home and abroad.

    Therefore, the Haidong Qing B-type aircraft uses a lower monoplane and a T-shaped vertical tail layout. The engine is the same wd-48sm turbofan engine used in the 15plus. It adopts a tail-mounted layout and places the engine under the vertical tail.

    The designed range is 4,200 kilometers with 50 seats. After the wd-50s large bypass ratio turbofan engine is put into production, the range will be increased to 5,500 kilometers with more seats.to 82 seats.

    The final third stage is the Haidong Qing Bplus, which will lay the foundation for future large passenger aircraft. The fuselage will follow the mature fuselage design of the Haidong Qing B, but the overall layout will be from a lower single wing, a T-shaped vertical tail layout, and an engine tail.  The hanging layout became the low-wing monoplane, high vertical tail, horizontal tail, and under-wing engine suspension layout used by Boeing and Airbus large passenger aircraft.

    ?The initial model uses wd-48sm turbofan engine, with a designed range of 4,500 kilometers and 46 seats; the mid-term upgrade model uses wd-50s large bypass ratio turbofan engine, with a designed range of 6,000 kilometers and 90 seats.

    The final model will use a large bypass ratio turbofan engine with a thrust of 10 tons that is being developed by Ascendas Group. The designed range will reach 9,000 kilometers and have 120 seats. It will become an advanced trunk transportation platform at the same level as the Airbus A320 and Boeing 737.

    Of course, there is still a long way to go to achieve this goal. At present, Ascendas Group's entire Haidongqing plan has just completed the first phase, and the second phase has just begun.

    So everything is still in its infancy, and because of this, in order to reduce costs and difficulty in development, Haidong Qing A type and Haidong Qing B, which has just started to be invested, are common in many places. For example, the warehouse dimensions are currently three models.  The width is set at 3.2 meters.

    In this way, the same standard, the same set of indicators and even the same production line can be used in the design and manufacturing of the nacelle bottom plate and stiffeners.

    The same is true for the central wing box, especially the core component of the wing box that connects the wings. Except for part of the connection process and assembly, the general manufacturing process of type A and type B is completely the same, which makes design and production very convenient.  It also greatly reduces costs.

    There is also a T-shaped vertical tail. The three aircraft are basically the same, and one production line can completely handle them.

    Because of this, although Ascendas Group has invested a lot of money in R&D and its stalls are staggering, the actual cost allocated to each aircraft model is actually not high. When mass production is carried out, the cost will be further diluted. In fact, each aircraft  The cost is surprisingly cost-effective.

    Coupled with the excellent performance of each model of Ascendas Group, it can be said that it is a rare cost-effective product in recent years.

    Various units, including the Air Force, have calculated this way, well, Ascendas Group¡¯s Haidongqing series is completely high investment and super high return. In this case, why are you still hesitating?  Just keep investing your money and that¡¯s it!
