Invincible Smart-Guy System

The data is correct, 24-hour continuous operation monitoring, thrust output is balanced and fuel consumption is balanced. Three new engines of Dongchen aviation engineering have completely relieved Boeing. The chief engineer of Boeing submitted a test report and officially approved the lifting and flight test of these three engines.

Raymond and Zhang Yunfeng discuss the test flight route with a group of Boeing test flight technicians. Paul, the technical director of Boeing test flight, thinks that the test flight should be carried out step by step, first on the ground, then on the take-off and landing test. During the course test, there are also many routes, from 100km to 20000 km gradually. The whole process is completed. It is estimated that it will take at least 20 days Between.

Zhang Yunfeng thought that this method was too inefficient, and said: "one day for ground taxiing test and take-off and landing test, and then began to prepare for the ultra long distance test."

"Super long distance?" Paul was not sure, and said: "the route test is generally to increase the range step by step. We need to let the crew thoroughly understand and be familiar with the performance of the engine, and then we need to analyze the data of multiple flight tests, and get the correct conclusion before we can carry out the ultra long flight test."

Zhang Yunfeng waved his hand and said: "all the ground tests have been done by Dongchen before the engine is delivered here. Now you have also confirmed that the data performance of the engine is stable and there is no need to delay for such a long time. After lifting, taxiing and landing tests are carried out to enable the technician to master the change of engine thrust and the speed of thrust climbing, The purpose of my joint flight test with Boeing is to carry out ultra long range test. If possible, I hope that the three planes will carry out global flight test at the same time. Your 777, 787 and 747 basically have a range of 1500001700km or so. With Dongchen engine, the range can be guaranteed to be more than 20000 km or even more than 23000 km. In the middle, you need to stop once to refuel Take off and land for one week around the world. "

"Here..."

Paul had no choice but to look at Raymond. In his mind, Zhang Yunfeng's idea is absolutely unique and bold. It totally runs counter to his professional background and all the people in the industry who are strictly in accordance with the rules and regulations. But in his mind, he also knows that Dongchen is the biggest development assistance of Boeing now. He can't face Zhang Yunfeng, only Can ask Raymond's opinion.

Raymond waved his hand casually at this time, and said: "just follow the general idea of Zhang, the manufacturing technology and level of Dongchen is the top in the world, and the parameters of the engine have also been verified by us. I don't think it's any problem to fly around the world. Even if the whole equator is only 40000 kilometers, the route will deflect a little more, and the longest is no more than 42000 kilometers, It's enough to make up the fuel in the middle of a stop and landing. You should make a proper route, and carry out the ground taxiing test and take-off and landing test tomorrow. "

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

As he said, he said: "actually, there is nothing worthy of in-depth study on the route. According to our current route resources, the most appropriate route is to fly from Seattle to Hawaii, then to Guam, and then to New Delhi, India. Because this route needs to meet the requirements of ETOPS, the actual flight distance of the whole route is about 21000km, however From New Delhi to South Africa, we will not land and then fly back to Seattle. The whole route is about 200002100km. "

Raymond nodded and said, "yes, this is just right. What do you mean, Mr. Zhang?"

Zhang Yunfeng roughly simulated the whole route in his mind, 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 said with a smile, "no airline can apply for a route more easily than Boeing. From Seattle to Guam, we don't need to apply for this route. We just need to submit a route plan to the American Aviation Administration. The same is true for the route back to Seattle in South Africa. We can apply for it in two days."

Zhang Yunfeng nodded and said: "then finish the lifting tonight and start the ground taxiing test and takeoff and landing test tomorrow."

The test flight engine is much simpler than the test flight of new aircraft. The 777, 787 and 747 provided by Boeing are all new aircraft in perfect condition. They have already obtained the airworthiness certificate in the world. The aircraft itself is very reliable. In this case, as long as the thrust of the engine is enough and the stability is enough, the whole test flight route can be completed.

At that time, Boeing had a large number of media stationed. After Zhang Yunfeng and Raymond and other Boeing personnel made a test flight plan, Dongchen's technicians began to enter the hangar overnight, and completed the engine hoisting in the hangar. The media also received the test flight message from Boeing staff. The specific plan is very simple. The ground test and take-off and landing will be carried out one day tomorrow Test, as long as there is no problem in the middle, the day after tomorrow or the day after tomorrow, Boeing and Dongchen will carry out the global flight test of the new engine together, and the whole global flight route is about 42000 kilometers long. In the middle, it stops only once in New Delhi, and it starts immediately when the fuel is full. Each aircraft is equipped with four crew, and it is expected that the stop time will not exceed two hours When.

This time, Dongchen is going to take the advantage of Dongchen engine in extending the maximum range in one step, and use the test flight of super long route to tell the global civil aviation that Dongchen engine is of great significance to the future international aviation, especially the trans Ocean Aviation. Not every airline buys a large number of aircraft with a maximum range of more than 15000 kilometers for long-distance flight Most of our wide body aircraft or large-scale aircraft have a range of around 1100km, some of which are even lower. When airlines are on duty for long-distance routes, because there are not many planes on hand that can reach at one time, most of them have to stop. This time, if the test flight of Dongchen is successful, it means that all of the wide body aircraft and large-scale aircraft in the future In the long-distance flight, there is no need to stop for fuel replenishment.

Moreover, Dongchen engine has better stability. The total flight time of global flight is about 6070 hours, and Dongchen engine can be fully competent for this kind of high-intensity flight, so that the utilization of aircraft by airlines can be further improved.

In the evening, the technicians of Dongchen have installed different types of Dongchen engines for three airplanes. The Boeing 777 and 747 hoisted the dc22787 and hoisted the dc31. It's a beautiful day. The next day, Seattle has a clear sky. The weather conditions can be said to be tailor-made for flying. The three airplanes were pushed out of the hangar at seven o'clock in the morning. The engine is printed with the striking logo of Dongchen In the morning the sun shines brightly.

Three aircraft started to start their engines after launching their respective hangars. Even if eight engines of three aircraft started at the same time, the engine noise was not harsh. Almost all the media cameras and cameras were aimed at the Dongchen engine of each aircraft. For them, the three models of the wave sound were basically bad streets. Now, the global concern It's all on the Dongchen engine hoisted under the wing of the aircraft.

The process of ground test is very simple. The engine starts, the aircraft taxies, turns and reverses. Basically, each of them does some basic actions within their own scope. The media would have liked to do something important, but after two hours, these aircraft are still repeating the same actions, which makes the media disappointed, and let the At last, they saw three airplanes preparing to line up at the end of the runway. One by one, they perked up again and waited to see the three airplanes take off from the runway.

However, they were disappointed by the actual situation.

The pilots of these planes didn't receive the take-off instructions from the tower. They just glided from the hangar to the runway, and then they lined up to turn back from the runway.

The media area was full of boos. Many people began to complain loudly to Boeing's staff. They came to prepare at five o'clock in the morning. Now, Boeing and Dongchen will show us this?

Boeing staff have no choice but to follow the command of the test flight center.

At this time, the captain of the 787 called the tower and said, "command center, B787 applies for takeoff and landing test, all engine indexes are normal, and the takeoff conditions are met."

At this time, Paul, the general manager of the test flight, said, "we can't enter the takeoff and landing procedures yet. Please continue the taxiing test."

Zhang Yunfeng said at this time: "let him on the runway!"

Paul exclaimed, "now on the track?"

Zhang Yunfeng nodded and said, "go on, and then slide down so dry. The reporters are expected to take the team back to lunch in advance."

Paul nodded helplessly and said, "OK."

"B787, please taxi to runway 34L, ready to take off, wind direction 060, wind speed 2 knots," he said

The pilot immediately replied, "take off from runway 34L, wind direction 060, wind speed 2 knots, understand."

At this time, seen from the tower, 787 has started to turn around and re-enter the runway. Media reporters thought that this time it must be fooled, one by one is still listless. After 787 stopped at the end of the runway, the turning sound of the two engines suddenly increased a lot.

"Here we are!" The quick response reporter immediately exclaimed, "engine thrust is on, this is about to take off!"

A large group of reporters immediately got up their spirits. The cameras and cameras were ready to see the 787 begin to accelerate and speed faster and faster. Then, the plane lifted its nose and took off smoothly.

This is the most desirable scene for reporters, and Paul simply did not do it for two times. First, he ordered B787 to rise to a height of 3000 feet, and then he ordered 777 to enter the runway and prepare to take off. Then, 747 was ready to enter the runway and take off after 777.

Zhang Yunfeng saw the media reporters in the distance immediately like beating chicken blood. He felt a move in his heart and said to Raymond nearby: "Raymond, please inform the reporters and invite them to participate in our global test. Anyway, we will simulate the plane with full weight at that time. It's better to take these reporters on the plane and use them to achieve the weight."

Raymond asked in surprise, "invite them to board the plane for the test flight?"

"Yes." Zhang Yunfeng nodded and said, "you can tell them that all the spare positions, except for our flight test personnel, can be provided to media reporters, and each media can only send up to three people to participate, until the newspaper is full."

"Good." Raymond promised, laughing: "I think the media will
