Chapter 345 obtaining airworthiness certificate

The flight test plan for several days is in full swing. The two planes are always taxiing, taking off, approaching and landing. After checking the engine, they take off again with fuel. Within a few days, the average flight time of the two planes has reached 70 hours, and the engine is in good condition. The final test, the fifth fuel range test, has also been completed After entering the preparatory stage.

The senior leaders of the high-level and civil aviation departments are very concerned about the test flight of Dongchen and have great confidence in Dongchen. This is also the reason why when Dongchen has formulated the test flight route, the senior leaders not only have no doubt about it, but also closely cooperate with the relevant work. In order to ensure that everything is safe, the whole flight is conducted along the third step of the mainland of China, because the third step Ladder, that is to say, the East, middle, Southeast and northeast areas of the whole continent are the most developed areas of China's economy, and only this area can meet the conditions of having an alternate airport every 300 kilometers.

Since the whole voyage is to test the maximum fuel range of 737 and 320 after the installation of dc11, according to the estimate, the maximum voyage can reach at least 55006000 km, and the test should be carried out according to the cruising altitude and speed, so it is impossible to circle the sky over Zhonghai city all the time. This route is made from Zhonghai to Yanjing, then from Yanjing to Shenyang, and then turn back the original road Go back to Zhonghai, then fly directly to Yanjing from Zhonghai, and turn back to Zhonghai from Yanjing. The total voyage is about 5500km. At that time, depending on the fuel conditions, if there is enough left, circle around the territory of Zhonghai until the fuel is exhausted.

The two aircraft are not running without load, but are applied to the standard full load counterweight by the tester to simulate the fuel consumption performance and fuel range during the real operation. All civil and military airports of the whole route are open to the two test flights of Dongchen. As long as the crew of Dongchen puts forward the demand, the aviation control department will let the nearest aircraft in the shortest time The field is ready to land.

After all the routes have been confirmed and all the conditions have been met, Zhang Yunfeng boarded the Boeing 737, one of the testing machines, in the morning of a certain day. The two planes will take off at an interval of ten minutes. One day, one day, the other day, they will fly the same route on duty. The testing personnel also take two planes respectively and are ready for the test.

At 7 o'clock in the morning, all the west bound aircrafts of the two airports in China Sea are under the control of aviation, and all the west bound aircrafts make a detour around the southwest to the south for approach, while Dongchen's aircrafts are ready to take off at 7 o'clock.

Boeing 737 is the first one to rush into the sky. After taking off, the captain immediately adjusts the course and flies straight to Yanjing. The plane also climbs to the cruising altitude. It flies at the cruising speed designed by Boeing 737, followed by Airbus A320. Where the two planes arrive, the whole 11000 meter airspace is occupied. All the planes passing through the airspace are forced to change the altitude to achieve this goal Clear the air for Dongchen.

All the airports within the range of Dongchen's test flight have received the air traffic control instruction, and must ensure that the runway can be cleared within ten minutes after receiving the order. All the airports do not know that Dongchen is carrying out the most significant test flight in the history of civil aviation in this century. Whenever Dongchen's aircraft enters a fixed airspace, all the airports in the region are forced to limit the flow. The airport Flight delays have increased dramatically, leading to complaints from all over the country.

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

After the success of the test flight, Dongchen will repeat the same test flight for at least five times. After five times, as long as there is no problem, it will be enough for the stability and safety of dc11. At that time, Dongchen will take the lead in submitting the airworthiness certificate application to the Chinese government, and then publish all the test results and relevant video materials of dc11 to the world. At that time, I'm afraid that the whole world will Will the world be shocked by it?

A country that is even hard to make the world's second-class aero-engine suddenly has the world's top civil aviation engine. This news is just like the North Korean country, which has the world's top nuclear bomb overnight, with full explosiveness.

.

All the airports on the way almost collapsed. They thought that there was a special plane passing through their own sky. For a while, the air control was understandable. However, just a few hours after the control, a new control order was issued again. When both of Dongchen's planes completed the flight from Zhonghai to Yanjing and then to Shenyang, Dongchen's two planes turned directly over Zhonghai, Fly straight to Yanjing again.

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

After the 737 has completed nearly 5500 kilometers of journey, the fuel surplus shows that the aircraft has at least 300 kilometers of endurance capacity. In order to ensure that the aircraft can land safely at the test airport, the aircraft hovers over the China Sea until the fuel is basically exhausted, and then it lands at the test Airport of commercial flight.

The A320, which followed, flew nearly 280km more than the 737 because of its original fuel range of 200km more than the 737 and the fuel economy of the new engine.

As soon as the two planes landed, the whole commercial flight test airport was boiling. In this test flight, the fuel range of 737 was 5800km, that of A320 was 6100km, which proved that the fuel economy of dc11 was unique in the whole civil aviation field.

The news was also directly conveyed to the senior leaders in the shortest time. The senior leaders were also excited about the success of dc11. Several congratulatory telegrams were sent, and the content of the telegram was a sound of praise.

In the following five days, the civil aviation aircraft of the third step of the whole mainland of China was not peaceful. Although there was no fault and abnormality in dc11, for the sake of safety, the following flight tests were conducted with the same degree of caution as the first one, without any negligence.

After the five-day test flight, Zhang Yunfeng submitted to the government the application for airworthiness certificate of dc11 of Dongchen. At the same time, Dongchen edited all the test process videos these days into a two-and-a-half-hour documentary, and authorized all the media around the world to broadcast the documentary free of charge.

The whole world is shocked by Dongchen! The world's people who know about the civil aviation engine are amazed by the performance of. Numerous media claim that Dongchen has brought the global civil aviation into a new field. The authoritative media in the world, such as CNN of the United States and BBC of the foreign Geely, have almost never stopped reporting on Dongchen. Boeing and Airbus also publicly say that dc11 of Dongchen is a major breakthrough in the field of civil aviation, and they are very willing to cooperate with each other as soon as possible Dongchen cooperates to produce the latest, the most environmentally friendly and the lowest consumption new aircraft.

Domestic civil aviation finally knows what the root cause of their frequent flight delays due to air traffic control in recent days is. However, at this time, they can't bear to complain. They contact Dongchen one after another to inquire about the approval of airworthiness certificate, and express their willingness to order new engines from Dongchen and complete the replacement immediately after the issuance of airworthiness certificate.

In just a few days, the share prices of Pratt & Whitney, general electric and Rolls Royce fell sharply, because investors knew that the excellence of Dongchen dc11, just like Dongchen automobile, could not be matched by other enterprises. The emergence of Dongchen dc11 means that the bankruptcy of these three enterprises is just around the corner.

The discussion on dc11 on the Internet has surpassed any other topic, and Internet users all over the world are paying attention to another major breakthrough of Dongchen. Just when Dongchen automobile has realized local production in the EU, Dongchen has set off a new revolution in the world's industrial field, and even some economists on Wall Street have given authoritative comments. Now Dongchen automobile is in the world The industry's production capacity has reached at least 50 million vehicles each. After annexing almost all joint venture production lines in China, Dongchen has acquired at least 70% of the production capacity of many famous enterprises, such as general motors, Ford, Chrysler, BMW, Mercedes Benz, Volkswagen, Fiat, Jaguar, Land Rover, Renault and Citroen, which is equivalent to more than half of the world's total production capacity of automobiles In terms of serving Dongchen, 50 million units are a conservative estimate. In this case, the valuation of the subsidiary Dongchen automobile alone exceeds 500 billion US dollars. The success of Dongchen's aeroengine makes the current valuation of Dongchen reach at least 650 billion US dollars. In addition, if the profit of last year is over 10 billion US dollars and the valuation is over 100 billion US dollars Dongchen pharmaceutical, the market value of Dongchen, is already twice that of ExxonMobil, the world's top 500!

However, it's just the market value. We need to know that Dongchen has not released even one ten thousandth of its shares to the outside world. If the huge financial empire announces its IPO in a certain period of time, the market value may double!

Now, Dongchen is not only an industrial empire, but also a financial empire. It is expected that more than 50 million cars will be sold every year. This is an irreversible situation, and it will only take time to prove. Now, the new engine developed by Dongchen avionics has not been put on the market With unparalleled competitiveness, people all over the world believe that as long as the country gives the airworthiness certificate to the Dongchen engine, as long as the international civil aviation organization gives the airworthiness certificate to the Dongchen engine, no airline can refuse the Dongchen engine, and the Dongchen engine will become their only choice!

And the efficiency of the government is also surprisingly fast this time. Only less than half a month later, dc11 obtained its airworthiness license in China. That is to say, dc11 of Dongchen can be sold to all airlines in the country!

Just after the government announced the approval of the airworthiness license of dc11, Dongchen immediately announced a single quotation of dc11 engine in mainland China, each of which costs 20 million US dollars, about 50% higher than the quotation of 13 million US dollars for the same level engine.

However, the 50% increase is also very cost-effective for airlines. First of all, Dongchen engine can save 40% of the fuel cost. Take 737 for example, the fuel consumption per hour is about 3 tons, and the current fuel price is about $1300 a ton, which means that every hour the aircraft flies in the sky, it can save nearly $2000 in fuel consumption, while Dongchen engine can save nearly $2000 in fuel consumption The multi million dollar engine cost can be recovered within thousands of flight hours. In terms of the utilization of civil aviation airliners, it is only less than one year and two years.

Fuel cost is only one aspect, afte
