Although it was determined that it was based on the TM-9 aircraft, Tengfei Group finally took out the same as the Yun-16, so that even his mother didn't recognize it.

This is not that Tengfei Group deliberately engaged in the superposition of new technologies, and it inexplicably improved the difficulty of the model, but it is really that the indicators given by the Air Force and major aircraft research institutes are too harsh.

First of all, the ceiling must be above 11,000 meters, so that the combat aircraft system on board the demonstrator platform can carry out practical testing and data collection in all directions at high, medium and low altitudes.

In addition, the country is vast, and in addition to the plains and hilly areas in the eastern region, the highland areas in the western region also need high-density tests.

Otherwise, how would it be possible to achieve all-airspace combat-ready cruise of combat aircraft?

Therefore, it is natural to increase the practical ceiling and optimize the take-off and landing performance of the plateau, especially the Tibetan plateau.

The second is noise control, because it is necessary to carry the test equipment of radar system and avionics system, and these equipment are often composed of sensitive components, which has extremely high requirements for the external environment, especially noise, which can easily cause interference and lead to inaccurate data reading.

This is also one of the important reasons why the major domestic aviation research institutions are not very interested in the Soviet Tu-154, it is really difficult to do a good job of noise control in the rough genes of the Tu-154, especially the three-engine zigzag layout of its tail, resulting in a surprisingly loud noise in the middle and rear sections of the cabin, coupled with the vibration of occasional air turbulence, it is difficult to obtain accurate data from the monitoring equipment stacked with sensitive components.

The third is safety, not to mention that the equipment carried on the plane is a high-value thing, and even many of them are imported from abroad at high foreign exchange prices, which can be called unique; let's just say that the chief engineers and experts who participated in the test are all first-class talents in the aviation field.

If something happens to the platform, falls or is destroyed, the loss is absolutely incalculable, and because of this, the security indicators of the platform are very high.

Finally, and the most critical is the cost, although the army and several major aviation research units support the Tengfei Group to do this so-called "modification" project, but the money of the troops and research institutions is not blown by the wind, not to mention that their lives are still tight, and they wish to break a penny into eight petals.

Therefore, the cost of the "modified" platform must not be high, otherwise several units together cannot afford it, so the platform must be optimized in cost.

Taken together, these indicators are an unprecedented challenge for any aviation manufacturer in the world, even for the American aviation giants.

Because this test is not only the production and manufacturing capacity of the enterprise, but a full range of technical background, if there is no sufficient technical accumulation, lack of technical digestion in the aviation field, even if the company looks very strong, which is just a vain fat man, but the real master of a heavy punch.

Can Ascendas Group work?

The answer is one word: yes.

Looking at the world, Tengfei Group may not be able to compare with the technology accumulation of European and American aviation giants in the past 100 years, but in China, Tengfei Group is definitely the enterprise with the most abundant technology accumulation.

This is mainly due to the continuous huge R&D investment of Tengfei Group, the aggressive technological innovation system and the open team R&D model.

Based on this, after years of development, especially the research and development of huge UAVs and the production of several fixed-wing aircraft, Tengfei Group has accumulated a large number of aviation R&D and manufacturing technologies with high added value.

For example, airtight cabin pressurization technology, such as carbon fiber aramid honeycomb composite material long fuselage integrated molding technology, and then advanced wing and T-shaped vertical tail structure......

As for the use of the rear engine layout in order to reduce the impact of noise on the engine room, Tengfei Group also has no shortage of precedents, and most of the bullet A provided to Company H that year, as well as a series of later derivative models, are engine rear layouts.

The same is true for drones that were later upgraded with turboprop engines, so Tengfei Group could not be more familiar with this layout, which is nothing more than changing from one engine to two.

It is difficult to assume the stability of the center of gravity and improve the flight performance, but the research on canard wings was carried out in the wind tunnel test project of various wing configurations carried out by Tengfei Group in cooperation with Professor Ding Laixiang, Lin Guanghua's mentor.

The results not only allowed Professor Ding Laixiang to obtain the title of academician of the Academy of Engineering, but also made Lin Guanghua's doctoral dissertation shine, so that Lin Guanghua, an in-service doctoral student who applied for a master's degree, successfully obtained a doctorate.

Therefore, in terms of canard wings, Tengfei Group is also not different, coupled with its own advanced materials and strong manufacturing capabilities, Tengfei Group seems to want to integrate these things accumulated over the years.

In fact, Ascendas does the same.

Of course, this period is not smooth sailing, many details of Tengfei Group can not be solved, but this project is supported by many domestic aviation research units, Tengfei Group is not a unit that silently drills the horns for the sake of face, of course, it is a variety of rubbing technologies that can pull strong reinforcements and pull strong reinforcements, and if they can't pull their faces, they will die on their faces.

After more than three years of busy work, the DL-11 "Science Fiction Star" finally completed its development and successfully made its first flight, and then after a series of tests, it not only met the requirements of the task book, but also jumped in some indicators, such as the maximum ceiling and maximum speed, which exceeded the performance of the indicators on the mission book.

This made the chief engineers and experts of the Air Force and other aviation research units extremely satisfied, and soon purchased two aircraft at a unit price of 6.5 million.

As soon as the first DL-11 "Science Fiction Star" was delivered, it was taken by Chenggong Aviation Manufacturing Company and began to be modified according to the requirements of the No. 10 project team for practical verification and testing tasks in the advanced radar, electronic equipment, nose fairing and canard wings of Project No. 10.

The second was booked by the Northwest Aviation Plant for system verification tests on fighter-bombers, as well as test verification of bomber electronic systems, communications command systems, and missile attack systems.

At this point, the general aviation production enterprises will be considered to have completed the task, and all that remains is to wait for the commendation of the superiors, collect the pennants or letters of thanks from the aviation research and development units, show their faces in the media and talk about the importance of this type of aircraft to the development of the aviation industry, and then ...... There is no then.

After all, it is a special project led by the state, and it is not easy to complete it with quality and quantity, so what else do you want to do?

However, Tengfei Group is never an ordinary enterprise, Zhuang Jianye is famous for squeezing the residual value of models, and it is simply an insult to the name of Tengfei Group if a platform with such excellent performance does not maximize its benefits.

So under the leadership of Zhuang Jianye, the DL-11 "Science Fiction Star" was treated as a trainee many years later, made a deep package, and prepared to make its official debut at next year's Paris Air Show.

As for the purpose, there are two words: make money!
