The large aircraft program follows a step-by-step development process. Judging from the development process of large foreign aircraft, basically the large long-range bomber is first, then the development of large military transport aircraft, and finally the large civilian passenger aircraft. This is the mature route of Boeing, the mature route of the Soviet Union, and at the same time the mature technical route of Europe.

When the Boeing Company of the United States was first established, it was not outstanding in terms of technology and production capacity, and it was still less than Douglas in the design of civil aircraft in the propeller era, but Boeing has always played the role of a new technology innovator in the development of civil aviation technology.

Boeing did not surpass the DC-3 model in the production of civil aircraft in the propeller era, but the Boeing 247, designed by Boeing in 1930 and put into operation by United Airlines in 1933, was the world's first passenger aircraft that met the standards of a truly modern civil aircraft, and the four-engine Boeing 307 stratoliner produced in 1938 was also the world's first passenger aircraft with a full-cockpit pressurized design.

During World War II and the early post-war period, Boeing's main production capacity was concentrated on multiple engine bombers, and a large number of long-range bomber design experience provided Boeing with a very strong technical foundation and design experience, and the jetization of aviation power systems also made Boeing more powerful in the design of large aircraft.

The U.S. Air Force commissioned the development of a large military transport aircraft project in the early fifties was a new opportunity for Boeing, and the 367-80 designed by Boeing became the basis for the design of military C-135 refueling/transport aircraft, and Boeing, with the consent of the U.S. Air Force, developed a civilian airliner on the basis of the C-135 large four-engine military transport aircraft, which became the pioneering work of Boeing in the jet era to stabilize the world's civil aviation technology-Boeing 707.

The Boeing 707, which was ahead of other rivals at the time, occupied the commanding heights of jet airliners, and after the success of the Boeing 707, Boeing developed the Boeing 727 and 737, two equally successful models, and Boeing stood at the top of the international civil aircraft market in the jet age through the development of the Boeing 707 and subsequent models.

Later, Boeing's project to compete with Lockheed for the U.S. Air Force strategic transport aircraft failed, but the technology developed for the CX-HLS program was instead used by Boeing for the large wide-body airliner program. The result of this project is the Boeing 747, an epoch-making large passenger aircraft.

The successful development of the Boeing 747 long-range wide-body passenger aircraft is Boeing's second major leap in civil aviation technology, and the production of Boeing 747 has further established Boeing's dominant position in the civil aviation market.

After the war, there were 55 Stratocruisers in service with American Airlines, British Overseas Airways, Northwest Airlines, Pan Am, and United Airlines.

The Boeing 377 is equipped with the same engines as the B-50 Super Flying Fortress, and the designers converted the strategic bomber to a passenger aircraft, with major improvements including a new pressurized fuselage, a passenger compartment climate control system, and a new wing midsection with turboprops for high power and a swept wing design.

This design makes the landing process very smooth, it is the largest, heaviest, longest-range airliner of its era, although it is equipped with a propeller engine, but its cruise speed, almost as fast as the newer jet, in many ways, it can be called a large jet airliner, and it is also the heaviest aircraft before the introduction of the Boeing 747.

In aircraft design, the wing is the core, and the engine and fuselage are a part of the wing. This may explain why bombers developed ahead of transport and passenger aircraft. The type of test wing is not a large passenger aircraft or a large transport aircraft, and a long-range bomber is the most suitable for this kind of mission.

The bomber will not be as comfortable and economical as a passenger aircraft, nor will it be as high-strength and short-distance as the transport aircraft, so the requirements for the fuselage will not be too high.

The high technology of a long-range strategic bomber is embodied in something in terms of radar light instruments, and not in the aircraft itself, and as for the instruments, you can use the instruments on existing aircraft. Designing from the start of the bomber is clearly the least costly and the most secure step. With a bomber flying out of the good wings of a big plane, there is a big plane. Fly out of the fuselage of a large aircraft with a transport plane, and fly out of comfort with a large passenger. Bombers can generally only use domestic engines and materials, which can also reduce the initial cost.

If you have your own long-range aircraft, the price of the aircraft engines or other parts that others sell will also be reduced.

The design of the wing of the bomber, do not think too much. Only the fast and long of the non-consider the non-fast, because of the need for external plug-ins, the bomber's wing is stronger than the large passenger aircraft requires. The bomb compartment is better than the transport compartment and the passenger compartment. The bomber can do some special actions that transport planes and passenger planes cannot do, and it is a limit test for the wings and fuselage of the aircraft, but it is too expensive to do this kind of test with passenger planes and transport aircraft, and it is not suitable to fall down.

With a large wing, as well as large aircraft flight data, and tested materials, the development of commercial aircraft will save commercial costs. Long-range bombers are not without benefits, and using long-range bombers against aircraft carriers or flying to the Americas is a reliable deterrent force, which can serve a purpose and return that cannot be achieved by economic means.

The turbofan engine of the long-range bomber will definitely be made in China, and it can be continuously improved in the process, for example, because of the long-range, the engine nozzle is changed to a mixed nozzle, which can save fuel, so that its own engine also has time to improve.

With the above improvements, there is more room for bargaining when producing commercial large aircraft and importing engines, or wing materials, or landing gear. Commercialization and military are accompanied, and the development of commerce in the West is accompanied by the process of military colonization, and the commercialization of domestic aircraft. Obviously, military support is also needed.

However, this time, the domestic large aircraft project has directly entered the design of large civil aircraft by leaps and bounds, which is a major reason for greatly reducing the time required, and the key problem is that now due to the improvement of computer design software and the popularization of supercomputer technology, it is feasible to talk on paper.

At present, although the supercomputer produced by Fan's Investment Group cannot be compared with the performance of the world's top supercomputers, it has become possible to provide these design services.

In addition, the addition of young designers has added a lot of new blood to the design team, and the complementarity formed by the combination of the old and the new has been given the greatest advantage.

Fan Heng and Fan Wuji, father and son, as well as the leaders who visited, were quite satisfied with the development of the base, especially for the fact that the progress could enter the actual manufacturing thing so long in advance, and they were very excited.

Hundreds of enterprises participating in this cooperation project across the country have established a dedicated Internet network in order to be able to report the progress of the project and the research and development status to the project team in a timely manner, and the company management system as the general control center can clearly see the latest progress and problems encountered by each enterprise.

With the full cooperation, many problems were solved by the experts in a timely manner, which was much more efficient than the previous meetings and research quarrels, which was very popular with the researchers.

You must know that in some previous debates, there were always many leaders who attended and listened, and these people may not be able to understand what the experts are saying, but there are many people who want to be experts, so it not only causes a waste of resources, but also makes everyone lack interest in this kind of exchange meeting.

The online communication not only increased the number of participants who could solve the problem. It also makes everyone's opinion completely and originally appear in everyone's field of vision, which is a great progress.

Fan Heng was in a high position and busy with affairs, so he naturally couldn't stay here for a long time, so after two days of inspection, he went back to the capital, but Fan Wuzhi stayed and continued to follow up some projects to see if there was anything he needed to contribute.

However, Fan Wuxian really can't help here, that is, to see where the money is needed.

But during the few days he stayed in Lingxi Province, there were many people who came to visit him. Including the provincial governor Guan Luping and the provincial party secretary Hu Kezhi and others came to greet him in person whether his residence was satisfactory or not, and also brought a lot of gifts.

Fan Wuxian knows in his heart, at the moment Fan Heng has a great chance of continuing to stay on the Standing Committee and Executive Vice Premier, obviously these people want to move around more and consolidate the relationship between the two sides, in fact, Fan Wuxian does not reject this, as long as the gift is not too outrageous, he will accept it.

In fact, once you reach this position, you don't need to worry about these little things, after all, those laws of middle and lower officialdom are not applicable in the middle of the highest level, unless you yourself have betrayed your relatives and left, it is unlikely that anyone will use this kind of small things to make trouble.

But a few days later, Fan Wuxian received a message from Panshi Airport, saying that there was something wrong with the airport's route management, and the air traffic control bureau did not plan to approve this year's new routes.

After hearing the news, Fan Wuxi felt a little stunned, he didn't expect that the people from the Civil Aviation Administration would have trouble with him.

When marketization fails to play its role in the left-to-right rush of administrative power, its rent-seeking inferiority will be exposed.

Many of the most advanced cases in the civil aviation system are related to the approval of route schedules.

Within civil aviation, popular routes and golden moments are known as lifelines, which directly determine the economic benefits of airlines. At present, it is not difficult to apply for the right to operate a certain route in civil aviation, but it is difficult to have flight schedules.

For example, the annual passenger throughput of the capital airport has exceeded 50 million passengers, but the maximum capacity of the capital airport at the peak of the hour is only seventy or eighty flights.

For airlines that have become competitors in the market economy, the allocation of flight slots in China's civil aviation is mainly through administrative allocation.

The Department of Transportation and the Department of Planning and Finance are known as the two most powerful departments of the Civil Aviation Administration, with the Department of Transportation in charge of aviation market access and the approval of routes and flight schedules, while the Department of Planning and Finance is in charge of civil aviation development planning, investment, and financial arrangements.

Although the approval power of routes and schedules is constantly being decentralized, and the routes of many airports have been changed from review to filing, the routes of those airports with the largest domestic throughput are currently approved by those airports. Still firmly in the hands of the Civil Aviation Administration of China and local administrations, the airports with the largest throughput are the lifeblood of airlines and the places where competition is fiercest.

Among them, the Capital International Airport is naturally the busiest airport in China and the most constrained airspace resources, and the North China Bureau of Civil Aviation, which has the right to manage flights at the Capital Airport, is considered to be the most powerful regional administration of the Civil Aviation Administration.

In the north of the Panshi Airport, which has a great influence, in fact, there are a lot of capital airports in terms of the number of passengers, but it is still too much in the cargo business.

At Kapanshi Airport is Xie Dongsheng, who is the director of the transportation department of the Civil Aviation Administration, who is responsible for the management of business licenses for public air transport enterprises and their routes, and has the right to approve routes and flight schedules that are related to the life and death of airlines.

In fact, I heard Panshi Airport say that in the complex aviation industry with a complex business chain, Panshi Airport and Fan's Airlines are not a special case, too scarce route resources and too concentrated time approval, has already created a black hole of power rent-seeking, the Civil Aviation Administration and the Civil Aviation Regional Administration have naturally become the key to grasping the economic lifeline of aviation enterprises, basically choking the throat of the benefits of aviation enterprises.

Fan Wuxian listened to the report of Panshi Airport and Fan's Airlines, and was very unhappy in his heart, now this is a sensitive time, he really doesn't want to make something happen, after all, he is about to open **, if he pokes out such a big case, according to his own code of conduct, he will definitely implicate a large number of department-level officials, which will make the high-level feel shameless.

If you want to let your father Fan Hengshun get through this re-election smoothly, the best response is to ignore this matter for the time being, and wait until the dust settles for the re-election before taking action, which is the safest way.

However, Fan Wuxian has been quite dissatisfied with the Civil Aviation Administration recently, and since they have already sent the pigtails to the door, Fan Wuxian does not mind attacking them, making them the victims of his father Fan Heng's powerful attack.

"Politics is always cruel." Fan Wuxian said.

There are no pop-ups
