After several days of test flight planning, the two planes were always taxiing, taking off, approaching, landing, and then after checking the engines, they refueled and took off again, and within a few days, the average flight time of the two planes had reached 70 hours, the engines were in good condition, and the final test, the fifth fuel range test, had also entered the preparatory stage.

The high-level and senior leaders of the civil aviation department are very concerned about Dongchen's test flight and have great confidence in Dongchen, which is why when Dongchen formulated the test flight route, the senior management not only did not have the slightest doubt, but closely cooperated with the root of the relevant work, in order to ensure that nothing went wrong, the entire voyage was carried out along the third tier of Chinese mainland, because the third tier, that is, the eastern, central, southeastern and northeastern regions of the entire continent is the most economically developed region in China, and only this region meets every 300 kilometers. There is a condition for an alternate landing airport.

Since the whole voyage is to test the maximum fuel range of 737 and 320 after the DC1-1 is assembled, according to estimates, the maximum range can reach at least 5500-6000 kilometers, and the test should be carried out according to the cruising altitude and speed, so it is impossible to circle around Zhonghai City all the time, this time the route is formulated from Zhonghai to Yanjing, and then from Yanjing to Shenyang, and then turn back to Zhonghai all the way, and then fly directly from Zhonghai to Yanjing, from Yanjing back to Zhonghai, The total range is about 5,500 kilometers, depending on the fuel situation, and if there is enough left, then circle around the territory of Zhonghai until the fuel is exhausted.

And both aircraft are not operating empty-loaded. Instead, the testers apply a standard full-load counterweight to simulate the fuel consumption performance and fuel range in real operation, and all military and civilian airports on the entire route are open to the two test flight aircraft of Dongchen, as long as the crew of Dongchen makes a request, then the air traffic control department will prepare the nearest airport in the shortest possible time to provide landing conditions.

All the routes are confirmed. And after all the conditions were met, one morning, Zhang Wenhao personally boarded one of the test planes, the Boeing 737. The two planes will take off ten minutes apart, one in front of the other and one on the same route, the testers. Also flew on two separate planes, ready for testing.

At 7 o'clock in the morning, all the westbound planes at the two airports of Zhonghai were subject to air traffic control, and all the westbound incoming planes made a detour from the southwest to the south, and Dongchen's planes were also ready to take off at 7 o'clock.

The Boeing 737 was the first to rush into the sky, and after taking off, the captain immediately adjusted its course and flew straight to Yanjing. The aircraft also continued to climb to cruising altitude, flying at a constant speed at the cruising speed designed by the Boeing 737, followed by the Airbus A320, and the two aircraft occupied the entire 11,000-meter airspace wherever they went. All aircraft passing through this airspace were forced to change altitude in order to clear the air for Dongchen.

All airports within the test range of Dongchen received instructions from air traffic control to ensure that the runway could be cleared within 10 minutes after receiving the order, and the airports did not know that Dongchen was conducting the most significant test flight in the history of civil aviation in this century. Whenever Dongchen's planes enter a fixed airspace, all airports in the area are forced to limit the flow, and the flight delays at the airport have increased greatly, resulting in repeated complaints from all over the world.

At this time, Zhang Wenhao was sitting in the cockpit of 737, watching the plane flying smoothly above the clouds, and he was very excited.

After the success of this test flight, Dongchen will repeat the same test flight at least five times, after five times, as long as there are no problems, it will be enough for the stability and safety of DC1-1, at that time, Dongchen will take the lead in submitting an application for airworthiness certificate to the Chinese government, and then release all the test results of DC1-1 and related video data to the world, at that time, I am afraid the world will be shocked, right?

A country that is even difficult to manufacture the world's second-rate aero engine, suddenly has the world's top civil aviation engine, this news, just like North Korea overnight, has the world's top nuclear bomb, with full explosiveness.

The plane flew smoothly, when it arrived over Yanjing, the plane turned to the northeast over Yanjing, flew directly to Shenyang, and after arriving in Shenyang, circled over Shenyang and turned back, and then changed to the southeast after going to Yanjing, and flew directly to Zhonghai.

On the way, all the airports were almost about to collapse, they thought that there was a special plane passing over them, and the temporary air traffic control was understandable, but just a few hours after the control, the new control order was issued again, and when Dongchen's two planes completed the flight from Zhonghai to Yanjing and then to Shenyang, Dongchen's two planes turned directly over the China Sea and flew directly to Yanjing again.

All airports between Zhonghai and Yanjing were controlled four times during the day

When the 737 completed the entire journey of nearly 5,500 kilometers, the remaining fuel showed that the aircraft still had at least 300 kilometers of endurance, in order to ensure that the aircraft could land safely and correctly at the test airport, the aircraft circled over the middle of the sea until the fuel was basically exhausted, and then landed at the test field of commercial aviation.

The A320 followed by the 737 with a fuel range of 200 kilometers more than the 737, plus the fuel economy of the new engine, so the aircraft flew nearly 280 kilometers more than the 737.

As soon as the two aircraft landed, the entire commercial flight test airport was boiling, this test flight, the fuel range of 737 flew out of 5800 kilometers, and the fuel range of A320 flew out of nearly 6100 kilometers, which is enough to prove that the fuel economy of DC1-1 is unique in the entire field of civil aviation.

The news was also directly conveyed to the senior leaders in the shortest possible time, and the senior management was also excited about the success of DC1-1, and sent a series of congratulatory telegrams, the content of which was a voice of praise.

In the following five days, the entire Chinese mainland third tier of civil aviation aircraft was not peaceful, although DC1-1 has not had any failures and abnormalities, but for the sake of safety, the next few test flights, the degree of caution is the same as the first time, there is no negligence at all.

After the completion of the five-day test flight. Zhang Wenhao submitted an application for the airworthiness certificate of Dongchen DC1-1 to the government, and at the same time, Dongchen edited all the test process videos into a two-and-a-half-hour documentary, which was authorized to all media around the world for free.

At this moment, the whole world was completely shocked by Dongchen!

DC1-1 performance. To the amazement of people around the world who know about civil aviation engines, countless media have claimed that Dongchen has brought the world's civil aviation into a new field. The world's authoritative media such as CNN in the United States and BBC in the United Kingdom have reported on Tungchen almost non-stop, and Boeing and Airbus have also publicly stated that Tungchen's DC1-1. It is a major breakthrough in the field of civil aviation, and we are very willing to cooperate with Dongchen as soon as possible to produce the latest, most environmentally friendly and lowest consumption new aircraft.

The domestic civil aviation finally knew what was the root cause of the frequent delays in their flights due to air traffic control in the past few days, but at this time, they had completely ignored the complaints, and contacted Dongchen one after another to inquire about the approval of the airworthiness certificate, and expressed their willingness to order a new engine from Dongchen and complete the replacement immediately after the airworthiness certificate was issued.

In just a few days. The stock prices of Pratt & Whitney, General Electric and Rolls-Royce fell sharply because investors knew that the excellence of Tungchen's DC1-1, like Tungchen Automobile, was unmatched by other companies. The emergence of DC1-1 means that the bankruptcy of these three companies is just around the corner.

The discussion about DC1-1 on the Internet has surpassed any other topic, and netizens around the world are paying attention to another major breakthrough of Dongchen, just when Dongchen Automobile has already achieved local production in the European Union, Dongchen has set off a new revolution in the world industrial field. Even Wall Street economists have given an authoritative evaluation, Dongchen Motors now has a production capacity of at least 50 million units in the world, and after merging almost all the joint venture production lines in China, Dongchen has obtained at least 70% of the production capacity of many well-known enterprises such as General Motors, Ford, Chrysler, BMW, Mercedes-Benz, Volkswagen, Fiat, Jaguar, Land Rover, Renault, Citroen, etc., which is equivalent to more than half of the world's total automobile production capacity serving Dongchen, and 50 million units are a conservative estimate. In this case, the valuation of the subsidiary of Dongchen Automobile alone exceeds 500 billion US dollars, and the success of Dongchen Aero Engine makes the current valuation of Dongchen at least more than 650 billion US dollars, in addition, if you add the annual profit of more than 10 billion US dollars and the valuation of more than 100 billion US dollars, the market value of Dongchen is already twice as high as ExxonMobil, which ranks first in the world's top 500!

However, this is only the market capitalization, you know, Dongchen has not released even one ten-thousandth of the equity to the outside world, this huge financial empire, if it announces the launch of the listing in a certain period of time, then, the market value may double!

Now Dongchen, is not only an industrial empire, more importantly, he has become a financial empire, is expected to sell more than 50 million cars per year, this is already an irreversible situation, and ultimately just need time to prove, and now, the new engine developed by Dongchen Aeronautics, has not really been listed, has unparalleled competitiveness, people all over the world believe that as long as the country gives Dongchen engine airworthiness certificate, As long as the International Civil Aviation Organization grants the airworthiness certificate of Tungstar Engine, then no airline can refuse Tungstar Engine, and Tungchen Engine will become their best choice!

The efficiency of the government is also surprisingly fast this time, and less than half a month later, DC1-1 has obtained its airworthiness certificate in China, that is to say, Dongchen's DC1-1 can be sold to all airlines in the country!

Just after the government announced the approval of the DC1-1 airworthiness certificate, Dongchen also immediately announced the price of DC1-1 engines in Chinese mainland, each priced at 20 million US dollars, which is about 50% higher than the quotation of about 13 million US dollars for similar engines.

However, this higher 50% is also very cost-effective for airlines, first of all, the Dongchen engine can save 40% of the fuel cost, taking the 737 as an example, the fuel consumption per hour is about 3 tons, and the current aviation fuel price is about 1300 US dollars a ton, which means that the aircraft can save nearly 2,000 US dollars in fuel consumption for every hour of flight in the sky, and the Dongchen engine is several million US dollars higher, within thousands of flight hours. You can recover the cost of overpayment, and in terms of the utilization of civil airliners now, it is only more than a year and less than two years.

Fuel cost is only one aspect, the later maintenance cost will also be greatly reduced, the theoretical overhaul time limit given by Dongchen engine is 6,000 to 8,000 hours, more than double that of ordinary engines. This is also a huge expense, and the reliability of the Topstar engine is very strong, and the failure rate is very low. If these are taken into account, and the fuel consumption savings are converted, the airline can recoup the overpaid cost of the Dongchen engine within a year. In the longer period that follows, Dongchen Engine will continue to save them a lot of operating costs.

The efficiency of the Chinese government has also boosted global airlines, including Japan and South Korea Airlines, all the airlines in the world that have placed orders for passenger aircraft to Boeing and Airbus, and the airlines that have not yet delivered the passenger aircraft have put forward a request to the two companies to suspend delivery, and their requirements are very unified, all the passenger aircraft that have placed orders will continue to be produced, but the previous engine cannot be assembled, and the delivery will be delayed until Dongchen Engine gets the global airworthiness certificate.

Airbus and Boeing immediately hairy. The delay in the delivery of more than 1,000 orders around the world is a desperate drive for both companies, and the aircraft order contract does not have absolute and immutable rules like ordinary purchase contracts, and the airline is entitled to a small amount of liquidated damages due to the high unit price of the aircraft and the long manufacturing cycle. In the past, this situation was only an isolated phenomenon, but if the world's airlines had to delay delivery, then Boeing and Airbus would not be able to cope with it.

Who could have predicted. The civil aviation field, which has long been stable, will suddenly emerge as an outlier like Dongchen, and his appearance will break the stability of the civil aviation field for decades almost instantly?

Boeing and Airbus jointly issued a statement that they rejected the airline's request for delayed delivery for orders that were already in production or about to be delivered, because even if the airline pursued the full payment, Boeing and Airbus did not have enough storage capacity in a short period of time to store those large passenger planes that should have been sent to all parts of the world, but the airlines refused to pay for the engines of Pratt & Whitney, General Motors and Rolls-Royce, and in the end, Boeing reached a consensus with Airbus and all customers that after the aircraft was manufactured, the manufacturer would be responsibleThe aircraft is hoisted with other engines and delivered to the customer first, and then the manufacturer is responsible for disassembling and transporting the engine back, and all the costs incurred are borne by the buyer and seller 50%:50%.

This solution has been recognized by customers around the world, they need planes, they also need Tungstar engines, it is impossible to cancel the Airbus or Boeing planes because of Tungchen's engines, the only thing they want is to be able to buy all the parts of the aircraft except the engine, and then, wait for Tungchen to open the global sales of DC1-1, and then buy more advanced engines from Tungchen.

Among other things, a 40% fuel savings alone is enough to drive airlines crazy! At this time, who else wants to spend money to buy the engines produced by the big three?

At the same time, the CAAC took the lead in holding a collective meeting in Yanjing, in which all Chinese mainland airlines attended except for the person in charge of Dongchen, and this time, the CAAC hopes that they can allocate resources to ensure that domestic airlines can get the quota given by Dongchen in a balanced manner, so as to avoid the emergence of a certain airline due to special channels, giving priority to getting a large number of new engines from Dongchen.

Zhang Wenhao personally attended the meeting, and at the beginning of the meeting, the person in charge of the Civil Aviation Administration said: "Due to the excellent performance of Dongchen DC1-1, we hope that before DC1-1 enters the market, we will rush everyone to come over and meet to avoid any uncontrollable situation." ”

As he spoke, the man said: "The so-called uncontrollable situation refers to the current domestic airlines, the competitive environment is relatively stable and fair, if the supply direction of Oriental is tilted at this time, so that a certain airline gets a higher quota, its cost will fall, which will bring great competitive pressure to other airlines." ”

The heads of all the airlines nodded again and again, and they were also afraid that one of them would be able to give priority to a large number of Dongchen DC1-1 because of special channels, so if the Civil Aviation Administration came forward to coordinate, then everyone could breathe a sigh of relief.

Immediately, the person in charge of the Civil Aviation Administration asked Zhang Wenhao and said, "Mr. Zhang, what standard can Dongchen's current monthly productivity reach?" ”

Zhang Wenhao said lightly: "The production line of COMAC is relatively small, although after a lot of transformation by us, the current productivity is still much worse than that of Pratt & Whitney, General Motors and Rolls-Royce, these enterprises, the monthly output of various engines can almost reach more than 500 units, and now if Dongchen is fully producing DC1-1, the monthly production capacity can reach about 200 units." ”

The person in charge of the Civil Aviation Administration of "Two Hundred" pondered for a moment and said: "The number of 737 and 320 in China is nearly 1,000, that is to say, in the domestic market alone, the demand for DC1-1 is about 2,000 units. ”

Zhang Wenhao smiled slightly and said: "Dongchen will immediately start investing a huge amount of money to expand production capacity, and it is expected that the output of the whole year this year can reach at least 3,000 units."
