Chapter 636

Yonghong factory has reached a united front and is ready to make a firm determination to fight to the end.

Yodel was staring at the flying "science fiction star" in the sky, and his trembling heart began to shake.

With such a sci-fi shape, such an avant-garde design and unparalleled flight performance, if its technology can be introduced back, it will be more important to Leipzig than the special engineering helicopters such as "small forklift".

You know, in the field of aircraft manufacturing, the biggest profit margin is the large passenger aircraft produced by Boeing and Airbus, followed by the high-end private business aircraft with superior performance.

Just like luxury goods, the target customers of high-end private business airplanes are all rich people without exception. Because of this, even if the production of high-end business airplanes is not too large, the profits of each plane are amazing.

This market is basically monopolized by the American continent. Bombardier in Canada, beech in the United States, Cessna in Brazil, Embraer in Brazil It covers almost 80% of the high-end business aircraft market.

In Europe, there is only one French Dassault, which is all right. Dassault's Falcon series of high-end private business jets follow the route of medium-sized aircraft. Most of its customers are government affairs aircraft of various countries. Of course, the rich also have them, but most of them are the leaders of those large consortia.

Those who start their own businesses or inherit their property are deterred by the high cost of Falcon series high-end private business jets.

Of course, in addition to market factors, the most important thing is that the flying "science fiction star" has the potential to become a high-end private business jet in terms of shape, performance and cost.

Originally, Yodel didn't know about the deep-seated things, but there was Gu Jingyou next to him. When he heard the other party shout out the three words "science fiction star", Yodel became interested, so he got close to the water first, and soon felt the performance of "science fiction star".

The official model of "science fiction star" is called dl-11.

The fuselage is 14.6 meters long, with a wingspan of 17.8 meters and a height of 4.2 meters.

The interior cabin is 6.2m long, 1.7m high and 1.8m wide.

3.2 tons in the air.

The maximum take-off weight is 6.5 tons.

The practical lifting limit is 12600 meters.

The maximum flight speed is 782 kmh.

Under the standard load of two pilots, six passengers and one flight attendant, the maximum range can reach 2857 km and 3109 km under no-load condition.

The engine adopts two wd-30jf turboprop engines produced by Tengfei and aviation power. The maximum power of a single engine is 756kw, and the shaft horsepower reaches 1013hp. The two engines can provide super power of more than 2000hp.

In addition to wd-30jf turboprop engine of Tengfei group, pt-6 series of Pratt & Whitney or similar engines produced by other general aviation power enterprises and RORO can also be selected for power.

Avionics adopts the customized avionics system produced by Honeywell of the United States, or similar products produced by Dassault of France.

As the engine adopts the rear layout, the noise of the propeller is greatly reduced. Therefore, the noise control in the cabin is very good, not to mention compared with the same level of high-end private business aircraft, that is, compared with the large private business aircraft, the noise index control is also excellent in a mess.

In addition, the canard wing configuration is adopted in the front section, so that the low speed performance of the whole machine is very good, and the minimum stall speed is controlled at 28 kmh.

This index is lower than that of ordinary single pilot small aircraft.

Such a low stall speed greatly increases the safety of the aircraft, because the lower the speed is, the pilot will have enough time and firm confidence to deal with the situation in an emergency, and will not fall into the dilemma of too low speed leading to the failure of the aircraft stall.

High ceiling, fast speed, long range, high safety, all of these two factors together, is the best gene of the most perfect high-end private business aircraft.

Once this model can be introduced to Leipzig, whether it is popular or not, Leipzig will take a new step in aircraft manufacturing.

Because of this, the topic of Yodel and Gu Jingyou soon changed from helicopter to dl-11 "science fiction star".

This makes Gu Jingyou a little uncomfortable. After all, he is engaged in helicopters. Although he knows something about fixed wing aircraft, he doesn't know much about it. In this case, how can he be so bold?

Of course, more importantly, he always admired Zhuang, who was about his age, from the bottom of his heart.

As for why, it's very simple that the "science fiction star" in the sky is the tail of the crane in many products of Tengfei group. Even the yun-16, which is refitted from the IL-18 airliner, is much stronger than the plane in the sky.

After all, after the delivery of two production models of yun-16, the Aerospace Department felt that the performance of this aircraft was very good, so it purchased three retired IL-18 aircraft from the air force and handed them over to Tengfei group for refitting, which was used for the rapid transportation of large aerospace structural parts.Because of this, the output of Yun 16 will reach 5.

What is the initial estimated production of dl-11 "science fiction star"? Two.

Yes, I'm right. It's two. That's all. We can't get any new orders within the foreseeable time. That is to say, according to the plan, dl-11 "science fiction star" is an out of print special model.

The reason for this is that there is only one original purpose of dl-11 "science fiction star", which is to undertake part of the performance test of domestic advanced fighters and bombers.

As an important part of aviation technology research and development, the verification machine is essential. However, due to the long-term backwardness of domestic technology and the shortage of funds, the technical verification machine is not outstanding.

In general, it is refitted with active fighters, supplemented by wind group model validation.

However, this method can also be applied to the second generation aircraft. In the third generation aircraft, because of the use of a large number of advanced technologies, the modification and wind group test of fighter obviously can not meet the development requirements.

We don't need to talk about it, but as far as the collection of test data is concerned, the space on the fighter plane is narrow and many large-scale equipment can't be put on it. Even if the required data can't be collected, it's useless.

Therefore, a test and verification aircraft that can be equipped with data acquisition platform for advanced fighter or bomber radar, avionics system and partial start-up has become a kind of aircraft urgently needed by major aviation research and development units and the air force.

According to international practice, it is most appropriate for similar aircraft to be refitted by civil aviation aircraft. The problem is that most domestic aircraft are imported, especially those from western developed countries. When they are introduced, they clearly want to participate in military use, so Airbus, Boeing and McDonnell Douglas cannot be refitted.

There are no such restrictions on Soviet aircraft. However, most of the domestic passenger aircraft made in the Soviet Union are seriously aging. Some Tu-154 and other passenger aircraft imported in the mid-1980s are unable to bear such heavy responsibilities because of their poor safety. After all, the test and verification aircraft itself bears great risks. If there are problems with the safety of the platform, it is really difficult to bear the heavy losses in case of an accident to measure.

Just when the superior units were at a loss, the special verification aircraft for fly by wire control system, the predecessor of tm-9 aircraft, came into the view of the chief engineer and leaders. After making a detailed evaluation of the predecessor of tm-9 aircraft, the air force issued a task letter to Tengfei group in July 1988 to refit two test verification aircraft with tm-9 aircraft.
