The first section introduces the noise chapter of p75. Liang Yuan has a rough look, and all the indicators are lower than the listed competitors. The faa also requires the third-stage noise standard to be similar to the passenger plane projection noise, which is much higher than the fourth-stage standard, which means that even if the noise reduction level of p75 is stagnant now, the noise level can be maintained until 215 years later.
However, looking at the data of Boeing 7375 and McDonnell Douglas 7 in the passenger plane comparison model, Liang Yuan confirmed the idea of the Federal Republic of Germany. If the Federal Republic of Germany enters the trunk narrow-body passenger plane, which specially pulls these two big guys with a take-off weight of 60 tons?
Noise is not the point. It’s good to be qualified. Liang Yuan didn’t look carefully at the detailed comparison data of p75 with Boeing 7375 McDonnell Douglas 7 and other passenger planes, and directly turned over a page.
A schematic diagram of a plane that then boarded the covered bridge and cargo transport belt appeared in front of Liang Yuan, which seemed to be a passenger plane passing by.
For airlines, this data is a ten-point index in choosing aircraft guneg. If the aircraft is shorter than shijian, it means that the aircraft day shijian means that the airlines make money. Therefore, if it is shorter than shijian, it means that the aircraft has higher interest rates and the airlines have more profits.
For example, the passenger planes of Southwest China Southern Airlines and Ryanair Airlines in Europe, which are profitable in the air transport industry in later generations, fly as high as 112 hours every ri day, while the three major airlines of the Republic, Air China, China Eastern Airlines and China Southern Airlines, can do it for 9 hours at the same time.
Approaching the covered bridge door, passengers, unloading luggage or goods, clearing and repairing, replenishing shelves, replenishing oil and water, loading luggage or goods, boarding new passengers, and the door is ready to take off for 25 minutes.
At the top of the data, it is marked that the d7 train takes 56 minutes, and the Boeing 7375 train takes 45 minutes. If this thing is really made, it will be the airline’s favorite.
Liang Yuan remembers that when he was lying down with sister HNA in his previous life, he heard that the fastest record for the Republic Boeing 737 was that China Southern Airlines made the 737 model create 42 minutes.
It’s a pity that in the decade, engineers who knew the airplane economy and knew the sound of civil aviation and aviation industry in the Republic of China were almost beneficial to introduce passenger planes or inspect passenger plane projects. Most of them were transferred from the Soviet Union or from the military aircraft field, and the lack of market economy concept eventually led to the p75, an excellent passenger plane, passing by the Republic.
Liang Yuan sighed and continued to flip the data.
The following parts are all safety information such as detailed indicators of various temperature motivations and ing energy of Liang Yuan’s not quite sure about the runway pressure caused by the single cruise approach tire of ingbai.
Considering the seriousness of airworthiness certification in the United States and Europe, ing Liang Yuan has no shie to worry about, and the Germans should not encounter difficulties in this respect.
After turning over more than half of the data, jingshén finally found the key data that determines the success or failure of a passenger plane. The fuel ratio of p75 is still to be continued …
Chapter 179 epoch-making airliner (4)
Later generations, Boeing and Boeing kept bickering and throwing dirty water at each other before launching new models. The most important data for both sides of the war and the airlines watching the ball is the fuel cost of each passenger plane.
In the era when the oil price soared like a rocket, this data determined the life and death of a large passenger plane and the life and death of the airline that operated this passenger plane. Now Liang Yuan finally saw the most important location of the whole information.
P75 gives the data chart, which is extra concise, and the standard counting mileage of the distance between the vertical axis and the kilometer makes the passenger capacity of 9 people p751, the fuel consumption of which is made into a shadow square reference. The horizontal coordinate axis marks the passenger 115 people p752, the passenger 1 bae2, the passenger 96 people bae3, the passenger 17 Fogg 1, the passenger 132 people Boeing 7375, and the passenger 13 McDonnell Douglas 7. At present, the most advanced narrow trunk line equipped by the ball airline company is compared with regional aircraft data.
If the fuel consumption of 9 passengers (p751km) is spread evenly to the value of 1 per seat, the fuel consumption of 115 passengers (p752) will be 16% less than that of P751.
The fuel consumption of one passenger bae2 is 71% higher than that of p751 and 47% higher than that of the new bae3.
The standard regional aircraft has just been delivered in six years, which makes the fuel cost of 17 passengers in the Netherlands Fokker 1 regional aircraft 13% higher than that of 9 passengers in p751. The fuel cost of more passengers is actually higher than that of fewer passengers. Generally speaking, this situation will occur only when there are aircraft with generation differences. This shows that there is a huge gap in the aviation industry level between the Netherlands and the Federal Republic of Germany.
Boeing’s strength is really extraordinary. With the legendary swordsman’s capital, it was delivered one year earlier than Fokker 1 regional aircraft, which made the fuel cost of each seat of the 7375 aircraft 2% higher than that of the p751, while the same seven-year delivery made the fuel cost of each seat of the three giants of trunk passenger aircraft, McDonnell Douglas 7, 11% higher than that of the p751.
From this simple data comparison, we can see that McDonnell Douglas failed in the future.
After reading this most critical data, Liang Yuan breathed a sigh of relief. Although all kinds of data in front have already indicated that p75 is a very advanced passenger plane, Liang Yuan still feels relieved after reading this most real data, and there is no doubt at all.
However, is there any reference in the reality of this contrarian thing made by the Germans? Liang Yuan pondered over whether p75 is a desert eagle or a second artillery Dongfeng 41 for the aviation industry of the Republic with a kitchen knife at present, which is a problem worthy of study.
Liang Yuan first remembered that Liang Yuan, one of the two powerful companies in regional aircraft and the Brazilian Aircraft Industry Company, had just decided to show a few guests before wearing it. The new generation e175e2 regional aircraft will continue to maintain the competitiveness of the Brazilian Aircraft Industry Company 22 years later.
It’s almost the same as the passenger p751 with 9 passengers. e175e2 has a basic maximum takeoff weight of 4,433 kilograms and a range of 3,356 kilometers. Compared with the maximum quotient of 131 kilograms, the most important weight capacity of a large passenger plane is still not as good as that of 15 kilograms p751 for an extra 3 kilometers. Liang Yuanjian believes that p75 will fly further than e175e2 with the replacement of a new generation of turbofans and the deepening research in the field of human fluid mechanics.
Industry is really not something that any country is qualified to play. The so-called Brazilian aviation industry has been expanding for five years, so much so. Except for the Republic, the remaining emerging industrial countries are really like bubbles. On the surface, they are colorful and beautiful, and when they are serious, they are exposed.
There is only one regional aircraft giant left, Bombardier. With the example of Industria Brasil, Liang Yuan didn’t think about Bombardier’s fame, but directly recalled Bombardier’s latest series passenger plane.
Series passenger planes are directly defined by Bombardier as single-channel narrow-body medium and short-haul trunk passenger planes. The future competitors are Boeing 737 and Boeing a32, Lena I, Paris Air Show 21 and 211. Liang Yuan has also entered the segmented cockpit several times to experience this epoch-making environmental protection passenger plane called by Bombardier.
Series passenger plane is Bombardier’s exhibition plan since it was launched in 24 years. The whole plan is expected to invest 300 million US dollars, with a fuselage diameter of 32 meters and a cabin width of 31 meters, which is 75 centimeters less than that of p75 passenger plane with a cabin width of 3,175 meters. This shows how funny it is that Germans have repeatedly stressed that p75 is a regional aircraft.
However, at that time, Bombardier was already monopolized by Boeing and Boeing. Although regional aircraft, the public aircraft market and railway equipment have made good achievements, it is a pity that compared with Boeing and Boeing, it is still a giant.
After Bombardier exposed his ambition, the customers and Boeing joined hands to set up obstacles and pressures in the procurement chain of the aviation industry ball, which led to no trunk passenger plane unified supplier dare to give Bombardier the aircraft parts he needed. Finally, Bombardier’s plan to enter the trunk passenger plane came to an abrupt end and was temporarily shelved.
This incident has had a huge impact on the aviation industry, which has a far-reaching impact on the fundamental interests of the country. The Canadian Prime Minister, the United States and the European Union, rushed back and forth to denounce the two groups for engaging in monopoly competition and threatened to sue the two groups in the EU Supreme Court and the US Federal Court.
The aviation industry chain suppliers are also afraid of the control ability of the two giants. After the game of ji1iè, Bombardier finally straightened out the same trunk passenger aircraft, found the trunk passenger aircraft supplier for himself, and then restarted the development of series passenger aircraft.
At this time, it has been six years since the second project of series was established. Before that, Boeing and Boeing launched the a32ne and Boeing 737a exhibition plans to fight against Bombardier series passenger planes.
At that time, the media of the Republic lamented the follow-up exhibition of the Republic arj21, the Brazilian Aircraft Industry Company e17e2, the Russian-class Su Huoyi 1st Mitsubishi Heavy Industries rj, and Kawasaki Heavy Industries yp22, and the field of medium and short-haul narrow-body passenger aircraft returned to the era of war at the end of the decade.
Bombardier series passenger aircraft has launched three exhibition models s1, s2 and s5, and the standard number of guests in single-class cabin layout corresponds to 125, 145 and 165.
The s1 data of 125 passengers in China is of great reference value to Liang Yuan. In Liang Yuan’s memory, the s1 fuselage length is 35 meters and the fuselage height is 115 meters, which is 14 meters high and 13 meters longer than the passenger p752.
S1 equipped Pratt & Whitney new generation geared turbofan engine has two power options: the maximum takeoff weight is 537kg at 4kn and 5967kg at n and 1453kg at n.
The maximum take-off weight of pne is 451 kg, and the maximum quotient is 14 kg. The maximum quotient of the two is similar.
In terms of voyage, the difference between the two is still a few kilometers. The s1 basic voyage is 277 kilometers, and the s1er extended voyage is 5463 kilometers, which is slightly better than p7522592 kilometers and er 4445 kilometers.
Liang Yuan gently closed his eyes and took a long deep breath to calm his excitement.
In a sense, p75 means that the Germans moved out the plan of Bombardier series passenger plane in Canada 15 years later. At that time, the reaction of passengers and Boeing was the best footnote for the competitiveness of this passenger plane.
The slide screen in front of the conference table was explained by the Germans about the advantages of p75. At this time, the translation sent by the Ministry of Foreign Affairs of the Republic was somewhat behind the German rhythm. After all, p75 technology is very advanced, and the technologies adopted are the most advanced in the world. Many technical terms have just been created.
Listening to the translator stuttering and explaining the benefits and concepts of flight control system, Liang Yuan took the desk note and wrote a sentence, I’ll do it, and then quietly pushed it to Liu Wenyue.
Liu Wenyue took the note, took a look at it, and then put the note into his pocket if anything happened.
When the Germans finished explaining a paragraph, Liu Wenyue indicated that he wanted to make a message and went out with the Germans for a while. Liu Wenyue also called out the translator sent by the embassy and returned to the conference room a few minutes later.
"I’m sorry for the delay. My colleague had a little problem there. Translation Wang went there for emergency. Let’s continue …" Liu Wenyue said and sat down.
However, Jiang Qingmin, the project leader of p75, was puzzled. Without Liu Wenyue, who was this talking to?
Then things made Jiang Qingmin very surprised. It was originally that he followed Liu Wenyue out to see the world. The teenager successfully accepted the translation work and the accuracy was better than that of Wang’s translation just now. Go out a few blocks.
There is a qualified language communication bridge, and the communication between the two sides has become extremely fast. In less than an hour, the general points of the whole p75 project have been finished, and then it took more than two minutes to review the advantages and disadvantages of the p75 project when the original turbofan engine was used, and how far is it from the actual development of the ge36 turbofan engine?
Bb Company attached great importance to Liu Wenyue’s arrival, and edmiston personally gave a lecture together with the prospect of international air transport for two hours.
After the whole project was finished, Ed Miston knew that this p75 backup plan would definitely be controversial. Liu Wenyue had to communicate with the Chinese p75 project engineers and simply ended the visit of bb Company.
On the way back, Liu Wenyue declined to send a car from bb company to discuss that Liang Yuan rented the small yacht and waited at the dock. Although the boat is not big, it is still rich.
Take the bb factory bottle car back to the dock and watch the white double-decker yacht Jiang Qingmin and others still waiting for the dock shore. Only then can they understand that Liu Wenyue said the day before yesterday that the newly established "Civil Aviation Import and Export Company" is a very special enterprise, and everyone will know in the future.
