Y20A civil airliner, the Airbus A340 four-engine long-range double-aisle wide-body passenger aircraft drawn by Yang Weiping is the overall shape frame, which combines the many advantages of Airbus A320 and Boeing 737, and is the fist product used by Tiangong Airlines to compete with Boeing 747 in the international civil aircraft market.

As one of the shareholder directors who do not participate in the day-to-day management of Airbus Europe, Yang Weiping facilitated the comprehensive technical cooperation between Tiangong Airlines and Airbus Europe after the establishment of Tiangong Airlines. It also submitted a proposal to the board of directors of Airbus to replace the CFM56-5A engine with the WS8-81A engine produced by Huaxia First Airlines.

The WS8-81A engine is specially designed for the Y20B Global Overlord. The core of the engine is the same as the WS8-80 engine. Compared with the WS8-80, the low-pressure section adopts a 24-blade wide-chord fan with a diameter of 1.55M, a new pressure stage, a double-ring chamber combustion chamber and a long-pipe mixed nozzle, and a second-generation full-authority digital electronic controller (FADEC), which reduces fuel consumption by 15% and improves reliability by 40%. Noise and pollution are significantly reduced, and maintenance costs are reduced by 15%.

WS8-81A KUNLUN ENGINE, TAKE-OFF THRUST 245 KNEWN, THRUST-TO-WEIGHT RATIO 5.5, AIR FLOW RATE OF 353.7KG PER SECOND, BYPASS RATIO 6.0, TOTAL BOOST RATIO 37.6, TURBINE INLET TEMPERATURE 1382 DEGREES CELSIUS, FAN DIAMETER 1836MM, LENGTH 2600MM, MASS OF 2267KG.

The engine has undergone rigorous testing by the expert technical teams of Airbus Aviation Europe and McDonnell Douglas Aviation in the United States. All indicators meet the design requirements, and its comprehensive performance is stronger than that of CFM56 series engines. And the price is only $3.1 million per unit. The cost performance ratio is significantly better than the CFM56 series engine launched by CFM International.

Yang Weiping designed the Airbus A340, which was originally not to be developed until 1988, and promised that Airbus Airlines in Europe could send a technical team to participate in the design and development of this new model, and the newly developed technology patents would be shared by both parties. This allows Tiangong Airlines to use a number of technical patents of Airbus A320 for free, thereby reducing the research and development cost of the Y20A civil airliner.

Ye Jianxiong personally inspected Tiangong Airlines, and Yang Weiping certainly had to show some achievements that he could get his hands on.

No, the second Y20A-300 prototype flight test flight plan held a week after the original plan was planned, ahead of schedule.

When Ye Jianxiong was accompanied by Yang Weiping to the Y20A civil airliner project team, a Y20A-300 airliner that had been fully painted was being pulled out of the huge factory by the staff. Slowly drive towards the take-off runway.

Ma Fengshan, the chief designer of Y20A, who is responsible for accompanying him. Chief Engineer Cheng kept explaining to Ye Jianxiong from time to time how superior and advanced Y20A was compared with the original 708 project.

Hailed by Airbus Airways and McDonnell Donnell Douglas (McDonnell Douglas) aircraft designers as the quintessential Y20A-300 aircraft, the Y20A family was laid the foundation for the larger and more advanced models of the "Y20A family" with a smaller WS8-81A engine and twin main landing gear.

The Y20A-300 can fly more than 16,000 kilometers while carrying 313 passengers in a three-class cabin. To increase the range. Additional fuel tanks were placed in the fuselage. The maximum take-off weight is 368 tons. Due to the excessively long fuselage. A camera was installed in the tail. It is convenient for the driver to stop at the parking position.

Based on the lessons learned from the safe flight of civil airliners at the cost of blood in later generations, Yang Weiping took the lead in proposing a new concept of adding an observer and second co-pilot behind the two pilots when designing the cockpit.

And this idea. It has also been recognized and approved by many senior pilots of the two major airlines of Airbus in Europe and McDonnell Douglas in the United States.

The Y20A-300 fuselage is 67.90 meters long, with a wingspan of 63.45 meters, a swept wing of 31.1 degrees, a height of 17.10 meters, a cabin width of 5.28 meters, and a wheel distance of 27.59 meters. The typical empty weight is 170,400 kg and the maximum take-off weight is 372,000 kg. It has a cruising speed of Mach 0.83, a practical limit of 11,887 meters, a range of 16,020 kilometers at full load, and a maximum fuel capacity of 214,810 liters. The engines are four WS8-8A Kunlun engines with a thrust of 245 thousand years.

The high-tech features of the Y20A-300 include a fully digital fly-by-wire control system, side-mounted joysticks instead of the traditional steering wheel, the same pilot rating as the twin-engine Airbus A320, a glass cockpit with a cathode ray tube screen, and a basic structure made of a variety of composite materials.

Seeing that this is bigger and longer than the Il-62, Boeing 737, Trident, Airbus A320, all the parts are made and produced by the four major aviation industry companies in China, the four-engine long-range civil aviation passenger plane is roaring into the sky on the 3,500-meter-long runway, Ye Jianxiong stood in place and looked up at the blue sky, until the Y20A-300 No. 2 prototype flew into the clouds and disappeared, still muttering to himself.

"If I hadn't seen it with my own eyes, I wouldn't have believed that our aviation industry could actually produce a world-class civil aviation airliner, I'm not dreaming......"

"Chairman Ye, you're not dreaming, it's all true!" Ma Fengshan excitedly introduced: "Before the No. 2 prototype, our No. 1 prototype successively flew to Shenyang, Dalian, Harbin, Urumqi, Guangzhou, Kunming, Chengdu and other places, and even broke through the 'death route' seven times and successfully flew to Lhasa, Tibet, transporting a large amount of urgently needed materials for the troops stationed in Tibet and the autonomous regional government.

The test flight of the No. 2 prototype this time mainly tested the airworthiness of the aircraft to the plateau airport and the adaptability to the severe cold climate. As long as all the destructive tests such as 'breakage safety' and 'safe life' are completed, there will be half a year at most, and our domestic civil aviation passenger aircraft will be finalized and put into mass production! We will no longer have to spend a lot of foreign exchange to import civil aviation passenger planes from abroad!"

The vice president of the European Airbus Company, who also attended the test flight at the scene, and the famous European aircraft designer Ablier congratulated Ma Fengshan, Cheng Bu and others through an interpreter: "Chinese colleagues, you have graduated! The success of the Y20A means that Tiangong Airlines will become a permanent strategic partner of Airbus in Europe! Congratulations on entering the ranks of the world's first-class aviation powers!"

"This is just the beginning!" Yang Weiping calmly held Ebley's right palm and said with a smile: "I told the board of directors three years ago that cooperating with Huaxia is a key step in the strategic transformation of Airbus Europe!"

"Your Excellency, I have to say that it was a very wise decision for the board of directors to agree that Your Excellency will replace the Field family as the new shareholder of the company!" Abliye looked at Yang Weiping solemnly and said: "I can now see that Tiangong Airlines will lead China's civil aviation product manufacturing industry to a more brilliant tomorrow!"

"Wei Ping, the second prototype of the Y20A has also been successfully test-flown yet, when will the first prototype of the Y20B Global Overlord be able to test fly?" Ye Jianxiong had regained his composure at this time, and smiled at Yang Weiping with great interest: "I'm a little impatient now!"

"It's coming, it's coming. Yang Weiping greeted Abliye, strode to Ye Jianxiong's side, and said with a smile: "Grandpa, your old man should know the Tao now, when the central government decided to agree that I would take over the follow-up research and development of Xinyun Ten, this step is not wrong!"

"Seeing the second prototype of the Y20A-300 today, and the test flight was successful, I am more confident in merging Huaxia First Airlines into Tiangong Group!" Ye Jianxiong nodded happily and praised: "What your godfather said is not wrong, Huaxia's aviation industry is really inseparable from you Yang Weiping if it wants to develop further!"

Ma Fengshan, Cheng Bu and others on the side heard Ye Shuai's words, and everyone's eyes couldn't help but have an irrepressible look of excitement.

No one can better understand what Yang Weiping means to Huaxia's aviation industry than them.

If Huaxia First Airlines can really be merged into Tiangong Group, they can fully say that in the future, Tiangong Airlines will never let international aviation giants such as Airbus in Europe, Boeing in the United States, and McDonnell Douglas dominate in the past. China's civil aviation industry will usher in a new round of rapid development!

Since its establishment, Tiangong Airlines has not only cooperated with Airbus in Europe and McDonnell Douglas in the United States to manufacture aircraft, but also carried out multi-faceted cooperation in the field of civil aviation service and management. To this end, the Tiangong Aviation Management College has also been set up in the Tiangong Aviation Science and Technology Industrial Park, which specializes in training civil aviation pilots, ground service personnel, passenger service personnel, airport management personnel and other civil aviation practitioners.

Tiangong Aviation Co., Ltd. will also be the first private joint-stock civil aviation airline in China. Tiangong Group holds 60%, Airbus holds 15%, McDonnell Douglas holds 15%, and another 10% is set aside for managed option shares.

Although the existing state-owned civil aviation companies in China are also shouting that they want to be in line with international standards. However, the rigid management mechanism is difficult to reach the advanced management level of old civil aviation enterprises in Europe and the United States in the short term.

Tiangong Aviation Co., Ltd. is a super catfish that has strengthened the process of enterprise restructuring of Huaxia State-owned Civil Aviation Company!

From the moment he took over the Xinyun 10 project team, Yang Weiping secretly decided not only to put his hand into the Huaxia civil aviation passenger aircraft manufacturing industry, but also to build Tiangong Airlines into the largest and strongest private civil aviation enterprise in China. In the sky of China's future, only civil airliners made in China can fly!(To be continued......
