Yonghong Factory has reached a united front, and is ready to strengthen its determination to fight to the end.

Yodel looked at the "science fiction star" flying in the sky in a daze, and his trembling heart began to waver.

With such a sci-fi shape, such an avant-garde design, and unrivaled flight performance, if the technology could be brought back, it would be far more important to Leipzig than a special engineering helicopter such as a "small forklift".

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

Just like luxury goods, high-end private business jets are all targeted customers without exception are rich and wealthy, which is why even if the production of high-end business jets is not too large, the profits per aircraft are surprisingly high.

And this market is basically monopolized by the American continent, Canada's Bombardier, the United States' Beechcraft, Cessna, Brazil's Embraer...... Covers almost 80% of the premium business jet market.

On the other hand, there is only one French Dassault in Europe struggling to support, and that's it, but Dassault's "Falcon" series of high-end private business jets are still medium-sized aircraft, and the customers are more government agencies of various governments, of course, the rich also have, but most of them are the heads of those big conglomerates.

Those who start their own businesses or inherit their family property are discouraged by factors such as the high cost of the "Hayabusa" series of high-end private business jets.

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

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

The official model of the "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 internal compartment is 6.2 meters long, 1.7 meters high and 1.8 meters wide.

3.2 tons in the air.

The maximum take-off weight is 6.5 tons.

The practical ceiling is 12,600 meters.

The maximum flight speed is 782 km h.

With a standard load of two pilots, six passengers and one flight attendant, the maximum range is 2,857 km, and the range is 3,109 km with no load.

The engine adopts two WD-30JF turboprop engines produced by Tengfei and Aviation Power, with a maximum power of 756 kilowatts and a shaft horsepower of 1013 horsepower, and the two engines can provide more than 2000 horsepower.

In addition to Tengfei Group's WD-30JF turboprop engine, the power can also be selected from Pratt & Whitney's PT-6 series or similar engines produced by other general-purpose, Rolls-Royce and other aviation power enterprises.

The avionics adopts a customized avionics system produced by Honeywell in the United States, and similar products produced by Dassault in France can also be used.

Because the engine adopts a rear-mounted layout, the noise of the propeller is greatly reduced, so the noise control in the cabin is very good, not to mention compared with high-end private business jets of the same level, but compared with large private business jets, the noise index control is also excellent.

In addition, the canard wing layout in the front section makes the whole aircraft very good for low speed, and the minimum stall speed is controlled at 28 km/h.

This indicator is already lower than that of ordinary single-piloted small aircraft.

Such a low stall speed greatly increases the safety of the aircraft, because the lower the speed, the more time and confidence the pilot has to deal with the situation in an emergency, and does not fall into the dilemma of being too low to stall the aircraft.

High ceiling, fast speed, long range, and high safety are all two factors that combine to make it the perfect high-end private business jet.

Once this model can be introduced to Leipzig, it doesn't matter whether it is a popular model or not, it will make Leipzig company step to a new level in the field of aircraft manufacturing.

Because of this, the topic of conversation between Yodel and Gu Jingyou quickly shifted from helicopters to DL-11 "Science Fiction Star".

This made Gu Jingyou a little uncomfortable, after all, he was engaged in helicopters, although he knew some fixed-wing aircraft, but he didn't have much, how could he be generous in this situation?

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

As for why, it's very simple, the "science fiction star" in the sky is simply the tail of the crane in many products of the Tengfei Group, and even the Y-16 modified from the IL-18 passenger plane is much stronger than the plane in the sky.

After all, after the delivery of the Y-16 in two production models, the aerospace department felt that the performance of this aircraft was quite good, so it purchased three retired Il-18 passenger planes from the Air Force and handed them over to Tengfei Group for modification for the rapid transportation of large aerospace structural parts.

Because of this, the production of the Y-16 will reach 5 aircraft.

What is the initial expected production of the DL-11 "Science Fiction Star"?

Yes, that's right, it's two, that's all, there will be no new orders at all for the foreseeable time, that is, according to the plan, the DL-11 "Science Fiction Star" is an out-of-print special model.

The reason why this is so is that there is no other reason for this, because the original purpose of the DL-11 "Science Fiction Star" is only one, that is, to undertake part of the performance of domestic advanced fighters and bombers.

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

In general, the modification of the active fighter is used, supplemented by the model verification of the wind group.

However, this method can still be applied to the second-generation aircraft, and when it comes to the third-generation aircraft, because of the use of a large number of advanced technologies, the fighter modification and wind group test obviously cannot meet the development requirements.

Not to mention the side, but as far as the collection of test data is concerned, the space on the fighter plane is narrow, and many large equipment cannot be placed, even if the required data is flown out as required, it will be in vain if it cannot be collected.

As a result, a test and verification aircraft that can be equipped with a data acquisition platform for advanced fighter or bomber radars, avionics systems, and partially activated test and verification aircraft has become an urgently needed aircraft for major aviation development units and air forces.

According to international practice, similar types of aircraft are generally modified by civil aviation passenger aircraft is the most appropriate, the problem is that most of the domestic passenger aircraft are imported, especially the passenger aircraft of Western developed countries, which are clearly required but cannot participate in military use when they are introduced, so Airbus, Boeing, McDonnell Douglas These large aircraft cannot be modified.

There is no restriction on the Soviet Union's aircraft, but most of the domestic Soviet-made passenger aircraft are seriously aging, and some of the Tu-154 and other passenger planes introduced in the mid-eighties cannot bear this kind of heavy responsibility because of poor safety, after all, the test and verification machine itself bears a great risk, if there is still a problem with the safety of the platform, once there is an accident, the loss is really incalculable.

After a detailed evaluation of the predecessor of the TM-9 aircraft, the Air Force issued a task book to the Tengfei Group in July 1988 to modify two test and verification aircraft using the TM-9 aircraft.
