With accurate data, 24-hour continuous operation monitoring, balanced thrust output and balanced fuel consumption, Dongchen Aerotech's three new engines completely relieved Boeing, and Boeing's chief engineer submitted a test report to officially approve the three engines for hoisting and test flights. ,!

Raymond took Zhang Wenhao and a group of Boeing test flight technicians to discuss the test flight route, Boeing test flight technical director Paul believes that the test flight should be gradual, first ground taxiing test, and then line test, also developed a number of routes, from 100 kilometers, gradually increased to 20,000 kilometers, the whole process is completed, it is estimated that it will take at least 20 years.

Zhang Wenhao thought that this method was too inefficient, and said: "After a short time, we will carry out ground taxiing tests and take-off and landing tests, and then we will start to prepare for ultra-long-range tests." ”

"Very long-range?" Paul was a little unsure, and said: "The route test is generally to increase the range step by step, and we must let the crew thoroughly understand and familiarize themselves with the various functions of the engine, and then analyze the data of multiple test flights, and draw correct conclusions before we can carry out ultra-long-range test flights." ”

Zhang Wenhao waved his hand and said: "All the ground tests, before the engine has been shipped here, Dongchen has already done it, and now you have also confirmed that the data performance of the engine is stable, there is no need to delay for so long, after hoisting, taxiing and take-off and landing tests will be carried out, so that the technician can grasp the change of engine thrust and the speed of thrust climbing, I have joined forces with Boeing this time to test the ultra-long-range test, if possible, I hope that the three aircraft will be tested around the world at the same time, The range of your White Spoon 777, 787 and 747 is basically about 15,000-17,000 kilometers, using the Dongchen engine, the range can be guaranteed to be more than 20,000 kilometers or even more than 23,000 kilometers. ”

"This"

Paul looked at Raymond a little helplessly, in his heart, Zhang Wenhao's idea is definitely very alternative and bold, completely contrary to his own professional background, everything is strictly in accordance with the rules of the industry practitioners, but he also understands in his heart that Dongchen is Boeing's biggest development boost now, and he must not be able to confront Zhang Wenhao, so he can only ask Raymond's opinion.

Raymond waved his hand casually at this time, and said: "Just according to Mr. Zhang's meaning, Dongchen's manufacturing technology and level are the world's top, and the parameters of the engine have also been verified by our white spoon, I don't think there is any problem in flying around the world, even if the entire equator is only 40,000 kilometers, and the route is deflected a little, the longest is not more than 42,000 kilometers, and a stop in the middle of the landing to replenish fuel is absolutely enough, you develop a more suitable route, and Ming Yao will first conduct a ground taxi test and take-off and landing test." ”

Paul nodded and said, "Then let's study the route." ”

Speaking, he said: "In fact, there is nothing worth studying in depth on the route, with our current route resources, the most suitable route is to fly from Seattle to Hawaii, and then turn to Guam, and then from Guam to New Delhi, India, this route because it meets the requirements of etops, so the actual flight distance of the entire route is about 21,000 kilometers, and then from New Delhi to South Africa without landing and then turning back to Seattle, the whole route is about 20,000-21,000 kilometers." ”

Raymond nodded and said, "Yes, this is just right, what do you mean, Mr. Zhang?" ”

Zhang Wenhao roughly simulated the entire route in his mind, and then nodded: "I have no opinion, you can negotiate with New Delhi, including all overseas routes during the period, and apply for it as soon as possible." ”

Raymond smiled: "No airline has an easier time applying for a route than Boeing, from Seattle to Guam, this flight does not need to apply, we only need to submit a route plan to the US Aviation Administration, and the same is true for the route from South Africa back to Seattle, and the rest, we can apply within two years." ”

Zhang Wenhao nodded and said, "Then we will complete the hoisting tonight, and tomorrow will start the ground taxiing test and take-off and landing test." ”

The test flight engine is much simpler than the test flight of a new aircraft, the 777, 787, and 747 provided by Boeing are all new aircraft in perfect condition, and they have already obtained airworthiness certificates around the world, and the aircraft itself is very reliable.

At this time, Boeing has a large number of media stationed, and Zhang Wenhao and Raymond and other Boeing personnel to make a test flight plan, Dongchen's technicians began to enter the hangar overnight, and in the hangar to complete the hoisting of the engine, the media also received the news of the test flight from the Boeing staff, the specific plan is very simple, tomorrow to carry out the ground test and take-off and landing test, as long as there are no problems in the middle, after the death or the big death, Boeing will carry out the new engine flight test together with Dongchen, Moreover, the entire route of the round-the-world flight is about 42,000 kilometers long, with only one stop in New Delhi in between, and it takes off immediately when it is fully fueled, and each aircraft is equipped with four crews, flying in shifts, and the stopover time is not expected to exceed two hours.

This time, Dongchen is to highlight the advantages of Dongchen engine in extending the maximum range in one step, and use the test flight of ultra-long routes to tell the global civil aviation Dongchen engine to the great significance of international aviation, especially transoceanic aviation in the future, not every airline buys a large number of aircraft with a maximum range of more than 15,000 kilometers for long-distance flights, most of their wide-body aircraft or large aircraft have a range of about 11,000 kilometers, and some are even lower. Since there are not many planes that can fly at one time, most flights have to stop, and this time, if Dongchen's test flight is successful, it means that all wide-body aircraft and large aircraft will no longer need to stop for fuel replenishment when flying long-distance routes.

In addition, the Dongchen engine has better stability, and the total flight time of round-the-world flight is about 60-70 hours, and the engine of Dongchen can be fully competent for this kind of high-intensity flight, so that the airline's utilization of the aircraft can be further improved.

In one night, Dongchen's technicians have replaced the three planes with different models of Dongchen engines, Boeing 777 and 747 hoisting Dongchen DC2-2, 787 hoisting DC3-1, the next day in Seattle the sky is clear, the situation can be said to be tailor-made for flight, the three planes were pushed out of the hangar at seven o'clock in the morning, the engines are printed with the eye-catching Dongchen logo, shining in the early morning sunshine.

The three planes began to start their engines after launching their respective hangars, even if the eight engines of the three planes were started at the same time, the noise of the engines was not harsh, and the cameras and cameras of the media were almost all aimed at the Dongchen engines on each aircraft.

The process of ground testing is very simple, the engine starts, the plane taxi, turns and reverses, basically each does some basic actions within their own range, the media originally wanted to play a little highlight, but after waiting for a full two hours, these planes are still repeating the same action, which makes the media disappointed, and let them finally see the three planes start to line up at the end of the runway, one by one, waiting to see the majestic posture of the three planes taking off from the runway.

However, the actual situation disappointed them again.

None of the pilots of these planes received take-off instructions from the tower, they simply taxied from the hangar to the runway, and then lined up to turn back from the runway.

There was a boos in the media area, and many people began to complain loudly to Boeing's employees, and they came to prepare at five o'clock in the morning.

And Boeing's job recruits have nothing to do about it, everything has to be under the command of the test flight center.

At this time, the captain of the 787 called to the tower and said: "Command center, B787 applies for take-off and landing test, and the engine indicators are normal and meet the take-off conditions." ”

At this time, the chief flight officer of the test flight said to Paul: "You can't enter the take-off and landing procedures for the time being, please continue to taxi test." ”

Zhang Wenhao opened his mouth at this time and said: "Let him get on the runway!" ”

Paul exclaimed and asked, "Get on the runway now?" ”

Zhang Wenhao nodded and said, "Come on, if you continue to slide like this, the reporters will probably have to close the team in advance and go back for lunch." ”

Paul nodded helplessly and agreed, "Okay then." ”

As he spoke, he turned on the communicator and said to the pilot of 787: "B787, please taxi to runway 34L, ready to take off, wind direction 060, wind speed 2 knots." ”

The pilot immediately replied: "Runway 34L takes off, the wind direction is 060, the wind speed is 2 knots, understand." ”

At this time, from the tower, 787 has begun to turn in place, turn around and re-enter the runway, media reporters thought that this time it must be fooled, one by one is a look of unhappiness, and 787 stopped at the end of the runway, the two engines suddenly turned a lot louder.

"It's coming!" The reporter who reacted quickly immediately exclaimed: "The engine thrust is turned on, this is about to take off!" ”

A large group of reporters instantly cheered up, cameras and cameras were ready, and saw that 787 began to gradually accelerate and get faster and faster, and then, the plane raised its nose lightly and took off smoothly.

This is the scene that the reporter has always wanted to see, and Paul did not stop doing it, first ordering B787 to rise to an altitude of 3,000 feet and circling, and then ordering 777 to enter the runway and prepare for takeoff, so that 747 was also ready to enter the runway and take off after 777.

Zhang Wenhao saw that the media reporters in the distance instantly seemed to be beaten with chicken blood, his heart moved, and he said to Raymond beside him: "Raymond, you go and inform the reporters, invite them to participate in our white spoon global test, anyway, we will simulate the full load counterweight of the plane at that time, it is better to bring these reporters on the plane and use them to achieve the counterweight." ”

Raymond asked in surprise, "Invite them to board the plane for a test flight?" ”

"Yes." Zhang Wenhao nodded and said: "You go and convey to them that except for our test pilots, all the vacant positions can be provided to media reporters, and each media can only send a maximum of three to participate, and the registration will end when it is full." ”

"Okay." Raymond agreed, and said with a smile: "I think the media will definitely rush to participate, but it is also very troublesome to bring them, and it takes at least three years to fly long distances, and you have to prepare meals for them, which means that you need to go to the airline to ask for at least six cabin service crews." ”

Zhang Wenhao said with a smile: "You contact United Airlines and ask them to prepare six cabin service groups, three to board in Seattle and three to wait in New Delhi. ”

“ok！”

Although we have already received the news that Dongchen and Boeing are going to join forces to conduct a global ultra-long-range test flight, the media reporters have never expected Dongchen and Boeing to let them board the plane, Bi Jing test flight is a very rigorous thing, and generally will not give media reporters the opportunity to participate directly at the beginning, but for Zhang Wenhao, the media has always been a free publicity tool for Dongchen, bring them to this test flight, and as soon as the plane lands in Seattle, it is estimated that the whole world will set off an overwhelming tracking report. This is a good thing for Dongchen, so why not do it?

The response of the media reporters was also very enthusiastic, almost all the media have registered, after the Boeing work has been counted, it was found that the number of registrations has been more than 1,000, which has far exceeded the number of seats that can be provided this time, Bi Jing plus a large number of test recruits and shift crews, flight attendants, these have occupied a considerable number of positions, and the positions that the three planes can provide to the media are only more than 700.

Raymond had to screen reporters, and in order not to let the media have much of an opinion, he did not reduce the number of media outlets, but reduced the number of entries that each media outlet could send from three to two.

The efficiency of Boeing's application route is also very high, in the afternoon, Boeing has applied for all the routes of the whole route, and the alternate airport in the middle has also been finalized, so Zhang Wenhao directly set the test flight time at two o'clock in Seattle time in the second afternoon, two o'clock, all three planes will take off within ten minutes, and then use the same route, and fly around the world at the same time.

The efficiency of Dongchen is so fast, if it is placed on the previous Big Three, I am afraid it will inevitably be labeled as irresponsible, the test flight of the aircraft is very rigorous, as soon as it comes up, it will carry out a transoceanic test flight, in case there is any disclosure and negligence in the middle or any immaturity in the design, I am afraid it will cause a big disaster, but for Dongchen, this company has been using super-first-class products to shape its own unparalleled credibility, so it is even a bit hasty to test the flight of Dongchen's high efficiency, There is hardly any criticism in the world, and even the media can't wait to witness the largest test flight plan of Dongchen, once Dongchen completes this test flight, then Dongchen will undoubtedly become the sole monopoly in the entire civil aviation engine field.

Zhang Wenhao will also board the B747 aircraft for the test flight, and participate in the entire test flight process, the upper cabin of 747 is not open to any media, at that time, Zhang Wenhao and Raymond will be here at the same time, the world's largest enterprises and the world's largest aircraft manufacturing enterprise CEOs are so assured of the B747 that has hoisted the Dongchen engine, and the media reporters have nothing to worry about?

The next morning, United Airlines Jingxin selected flight attendants rushed to Boeing's flight test site to prepare, and including all the meals in the air, also have United Airlines free of charge, they even arranged all the work after the plane landed in New Delhi, including fuel filling, flight attendant shift change and meal addition, etc., it can be said that for this test flight, United Airlines is also very helpful, Bi Jing They are now the largest airline customer of Dongchen in the United States, and they are also the airline with the largest revenue from Dongchen in the United States. Like Boeing, they regard Dongchen as their most important partner, and if Dongchen succeeds in this test flight, once it obtains the US airworthiness certificate, then United Airlines will have the opportunity to obtain Dongchen's engine in the first time, and at that time, they will have stronger competitiveness and profit margins on international routes.

All the media are also very consistent, they sent two interview teams, both are a reporter and a cameraman, at 12 o'clock at noon, the media reporters began to line up to accept the security check and in different order, board different planes, Zhang Wenhao and Raymond are still waiting in the office, the crew members set the registration time for them at 13 o'clock, so that you can avoid media reporters, and you will not be affected by the noisy environment, two into and other important members can directly board the top cabin of 747, the top cabin will be closed from the inside and will not be open to any outside entry.

At 13 o'clock, Zhang Wenhao boarded the Boeing 747 plane with Raymond and a bunch of Boeing technicians, after all the inductees boarded, the captain began to balance the load in the cabin of the current aircraft, and the ground maintenance workers are also loading the cargo for counterweight in the cargo hold, this time, the three planes will take off in an almost full state, and fly directly to New Delhi, the capital of India.

In the cabin, Zhang Wenhao asked Raymond: "Pratt & Whitney, Rolls-Royce have come to this day?" ”

"Nope." Raymond shrugged his shoulders and said, "Those people went back and didn't stay." ”

Zhang Wenhao asked in surprise, "What?" Aren't they waiting to see first-hand news? How did you go? ”

Raymond smiled: "They have mastered the approximate parameters of the Dongchen engine, and now, it is estimated that they will go back to study countermeasures." ”
