The elevating food truck has also been prepared for a long time. As soon as the plane lands, the carefully prepared meals will be sent into the aircraft through the elevating truck.

The maintenance staff also began to carefully inspect the aircraft to ensure that there were no problems with the aircraft.

The originally planned two-hour stoppage was delayed by about four hours due to various preparations.

The reporters outside the cabin never left for a moment. They gathered around the plane and took as many pictures as possible to pass on to audiences around the world. This feeling was just like when Magellan's men finally completed the circumnavigation of the world.

Extraordinary and extremely important.

After undergoing various supplies and inspections, the 747 requested permission from the tower to take off. The tower immediately cleared the runway. In front of countless joyful spectators, the 747 took the lead in taking off from New Delhi Airport, leading two other planes to South Africa.

Although for Zhang Wenhao, Dongchen and Boeing, this global flight has only completed half of the journey so far, for industry insiders and global audiences, when these three planes successfully landed in New Delhi and completed their respective

When it reached a range of 23,000 kilometers, it was equivalent to announcing to the world that this test flight was almost a complete success.

The rest of the route is planned, and the total distance is less than 22,000 kilometers. The three planes with full fuel can cope with the 23,000 kilometers on the way to New Delhi. Naturally, they can also cope with the remaining less than 22,000 kilometers. Even, everyone

They all firmly believe that when the plane finally flies over Seattle, the crew will also circle in victory over Seattle to show the world the unprecedented feat they have accomplished.

The citizens of Seattle learned that the return time of the three planes would be between 37-40 hours. A large number of citizens had already begun to calculate the time and prepared to go to the airport to witness this miracle with their own eyes. The media also continued to conduct ground monitoring based on the flight schedule.

Based on the information fed back from the station, we can estimate the specific location of the plane at this moment and the time it will arrive in Seattle.

Nearly forty hours later, at nine o'clock in the morning local time in Seattle, the 747 led the 777 and 787 to successfully fly into the Seattle airspace. Raymond was obviously too excited to add anything, although the protagonist of this test flight was Dongchen.

However, for Raymond, it was the three models produced by Boeing that truly accomplished the feat this time, so it was inevitable that he would be excited.

The plane entered the Seattle airspace, which meant that the flight was about to end. At this time, Zhang Wenhao was not thinking about how to celebrate this complete success, but was thinking about three things.

First: Dongchen, the high-thrust engine is on the market, and the production capacity has reached sufficient scale. The next step is to open the replacement window for airlines. This time, there is no doubt that it will still be from domestic airlines, to be precise, Continental Airlines

The company started, and soon, the United States and France, but at the same time, DC1-1 will also start to open the replacement window in other European countries. How to achieve a balanced distribution of production capacity is an issue that Zhang Wenhao needs to consider carefully.

Second: In the next step, several major military powers will surely begin to accelerate research and development in the field of military aircraft engines at all costs. And this time, senior leaders also sent three domestic experts to participate in Dongchen’s test flight. This also means that

Now, they are already interested in obtaining current military aircraft engines from Dongchen, and it is time for them to produce prototypes. After the prototypes are produced, if the Air Force is interested, they can directly take over the domestic Taihang production line for military use.

The production of engines will not occupy its existing production capacity.

Third: Although this test flight went smoothly, the designed cruising speed of most civil aviation aircraft is below 1,000 kilometers per hour, which means that the maximum speed their aircraft structures can carry is this high, and ultra-long-distance flights can easily carry dozens or twenty passengers.

Hours, the speed is really too slow. The original Concorde had to be said to be a great pioneering work in the field of civil aviation. However, the failure of the Concorde came from many aspects, including high cost, loud noise, and high fares.

As a result, the Concorde could only operate at a loss, and the final accident of the Concorde accelerated the demise of the Concorde. Since then, there has been no supersonic civil aviation technology in the world. If you can survive in this situation

Next, the launch of supersonic civil aviation services will be of extraordinary significance.

Supersonic civil aviation is a dream of Zhang Wenhao. If Xiao Er uses the knowledge in the super learning system to manufacture it, he can create a supersonic passenger aircraft with lower cost, higher safety and higher practicality, with a speed of up to

Mach 2.5, which is 3,000 kilometers per hour, is nearly 0.5 Mach higher than the Concorde. By then, a long-distance route of more than 10,000 kilometers can be completed in five hours.

Operating a supersonic passenger plane requires great courage and financial resources, but Zhang Wenhao has hatched a preliminary plan in his mind. If Dongchen acquires Airbus in the near future, then Dongchen will build a batch of supersonic passenger planes that will never be sold outside.

, then Dongchen will register its own airline and use its unparalleled important position in the global civil aviation field to develop supersonic passenger aircraft on the hottest long-distance routes, becoming the only one in the world capable of operating supersonic air transport.

enterprise.

Just as Zhang Wenhao was making plans for the future, the 747, amid the cheers of more than 100,000 Seattle citizens, was circling and consuming the last fuel while continuously increasing the range of the second leg to 23,000 kilometers until 11 a.m.

At one o'clock, the 747 finally circled over Seattle and consumed almost all the fuel.

The 747 landed first and when it turned to the apron, the ladder truck was docked and the flight attendants opened the cabin door. A large number of reporters wanted to gather around them, but they were stopped outside the apron by more than a thousand Seattle police officers.

At that time, the 777 and 787 also landed on camera. These three aircraft landed smoothly at the Boeing Seattle test field. Dongchen and Boeing jointly completed the most incredible and epoch-making test flight in the history of civil aviation.

Before getting off the plane, Zhang Wenhao said to Raymond: "Immediately arrange for BBJ2 to take off and return to China. I will rush back today. I will give you the engine I brought as a souvenir." (To be continued. If you
