Take Off My Aviation Era

From this point of view, the Air Force didn’t work anymore. If it didn’t control the military budget for the next few years, it would not be enough to fill in. So it decisively asked Ascendas Group not to spread the stalls so large and concentrate on one model.

result……

The Air Force still hasn't escaped the true incense law.

When Tengfei Group under pressure came up with four models derived from the concept of advanced light transportation platforms, the Air Force’s previous idea of ​​shrinking the defense line to attack a little bit was completely thrown into the old paper pile, and directly passed the results of Tengfei Group through the headquarters. Reported to the decision-making level, and then applied for a large wave of special grants, regardless of whether it was thrown into Ascendas Group.

There is no way that the four models are too tempting. Let alone the air force, the navy is a little eager to learn about the situation. As for the major domestic airlines, they are eager to learn about the situation.

Why, it’s very simple, the things that Ascendas Group has produced are good enough.

The four models have been equipped with the six Y-15 and four Y-15plus aircraft of a certain aviation group of the Airborne Corps. There are also two jet aircraft, which are internally codenamed Costin b and Costin bplus.

Of course, the Y15 and Y15plus are military model names after being equipped with the Air Force. At the beginning of the launch of the advanced light transport platform by Ascendas Group, the code names of these two models were also called Costin, but compared to the type b, Y15 The series is a type.

The combination of Type A and Type B is the core of Ascendas Group in the past five years, and it is also the most far-reaching plan for the future, that is, the "Sea Dongqing" plan sublimated from the concept of an advanced light transportation platform.

The plan is divided into three stages.

In the first stage, Costin a and Costin aplus are the cores, backed by the support of the military and the country, during the development of 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 complete the a-type and aplus at the same time, start the development of the b-type.

The final third stage was to complete the mass production of 70 to 100 feeder transport platforms in the late 1990s and early 20th century, laying the foundation for the development of medium and large transport platforms in the new century.

Based on this plan, Ascendas Costin’s A-type benchmark customer is aimed at the military, so it uses a single-wing, T-type vertical tail layout.

However, the positioning is not limited to the military. For example, the Yun-15 equipped with airborne troops, Ascendas Group actually positions it as a multi-functional dual-use platform.

It is a typical 46-seat regional airliner because the interior has been transformed into passenger transportation, with the addition of civil aviation navigation and communication equipment, and the addition of luggage storage, toilets and kitchens.

Designed for a voyage of 3,500 kilometers, it will immediately perform air transportation services in Tibetan plateaus and border regions, as well as medium-range passenger transportation services in inland provinces.

Based on this, the plan of Ascendas Group is to develop it into a professional turboprop transportation platform. When the wd-50j turboprop engine of the 3500 to 4200 kilowatt class is fully mature, the Haidongqing a with a more powerful engine will get With further improvements and upgrades, its take-off weight will reach 35 tons, making it an excellent turboprop feeder model with a range of 4,500 kilometers and carrying 76 passengers.

In terms of military use, the deeply upgraded Costin a will be more flexible and perform better.

Compared with Costin’s dual-use military and civilian use, Costin aplus is a completely military model. Regardless of the size of the cargo compartment, the take-off distance or the loading of items, it is designed completely in accordance with the combat needs of the unit, and there is almost no adulteration. Aspect things.

Therefore, Costin aplus will be the signboard and foundation of the military transport aircraft of Ascendas Group in the future. After the wd-50j turboprop engine is the same as the core machine, the wd-50s large bypass turbofan engine with 6.5 tons thrust is put into production, Costin The maximum take-off weight of aplus will be close to 40 tons.

By then, the upgraded Costin aplus will have a load capacity of 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. Regardless of other issues, the combat capabilities of the airborne troops, southern amphibious troops, and plateau and mountain troops will be greatly enhanced.

Compared with Costin a-type turboprops and turbofans, both military and civilian use are developed in parallel; Costin b started in the second stage is much simpler, and its main purpose is to target the growing domestic and foreign regional air transportation market.

Therefore, Costin’s B-type aircraft adopts a single-wing, T-shaped vertical tail layout, and the engine is a wd-48sm turbofan engine of the same type as the Yun 15plus. It adopts a tail-mounted layout and the engine is placed under the vertical tail.

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

The final third stage is the Costin bplus, which lays the foundation for future large passenger aircraft. The fuselage follows the mature design of Costin b, but the overall layout will be a single wing, T-shaped vertical tail layout, and engine tail. The suspended layout becomes the lower single wing, high vertical tail, horizontal tail, and under-engine suspension layout used by Boeing and Airbus large passenger aircraft.

In the initial stage, it uses a wd-48sm turbofan engine with a design range of 4500 kilometers and 46 seats; the mid-term upgrade uses a wd-50s large bypass ratio turbofan engine with a design range of 6000 kilometers and 90 seats.

The final model will use the large bypass ratio turbofan engine developed by Ascendas Group with a thrust of 10 tons. The designed range will reach 9,000 kilometers and 120 seats. It will become an advanced trunkline transportation platform at the same level as 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 Costin 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 the cost and the difficulty of development, Costin A and Costin B, which have just begun to be invested, are universal in many places~www.readwn.com~ For example, goods The size of the warehouse is currently set at 3.2 meters for the three models.

In this way, the same standard, the same set of indicators or even the same production line can be used in the design and manufacture of the nacelle floor and stiffeners.

The same is true for the central wing box, especially the core components of the wing box connected to the wings. Except for some of the different connection processes and assembly, the a-type and b-types have the same manufacturing process, which makes the design and production very convenient. Also greatly reduces costs.

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

Because of this, although Ascendas Group looks at a lot of R&D investment, and the stalls are staggering, the actual cost allocated to each model is actually not high. When mass production is further diluting the cost, in fact, each aircraft The cost is surprisingly cost-effective.

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

All units, including the Air Force, do so. Well, the Costin series of Ascendas Group is completely high-investment and extremely high-return. Since this is the case, why are you hesitating? Keep investing money and it's over!
