Chapter 610 The Hope of Transcendence

"Tell me, what do they want to do!" Yang Dongsheng said.

"One is a printer..."

"Printer?" Before Director Li finished speaking, Yang Dongsheng was taken aback.

Printers are commonly used tools in the office, and no one thought it was a great thing, until a female office clerk sarcastically said, "You are so capable, why can't you even make a printer?"

Several young people in the company investigated and found that it was true.

In the domestic market, whether it is inkjet printers or laser printers, more than [-]% of the market share is occupied by American and Japanese companies.

There are also printers of domestic brands. For example, a conscientious computer assembly factory, their printers are the domestic brands with the highest market share-at least they are still Chinese companies in this era.

However, adhering to their tradition of only doing assembly and resolutely not doing core technology, the core components of the printer in the computer assembly factory are all bought, and they are sold at an extremely expensive price.

A few young people disassembled the printer, and found that the most difficult parts were the core technologies. Inkjet printers consisted of ink formulations and nozzles, while laser printers consisted of photosensitive drums and toner.

In addition, chips must be used, which is their strong point.

Now that there are more and more office buildings in the country, the demand for printers is bound to increase.

Before the Gulf War, Iraq ordered an air defense command system from France, but the printers equipped in the computer center of the system used American chips. Paralyzed the system, and in the end Iraq had nothing but a beating.

The prospect of the printer is good, and safety concerns are worth considering, but this project was very controversial during the company's internal review.

First, printers are not in their future business map;

Secondly, the printer market is already very mature. After they make it, how many units can they sell?very doubtful;
Third, the company has launched a lot of new projects recently, and the financial pressure is very high.

"It's good to have ideas, but we don't have to make printers directly. Didn't they say that the core technology is ink formula, nozzle, photosensitive drum, toner and chip? We only make these core components, and it shouldn't take much money!"

Since the printers of the computer assembly factory rank first in the market share of domestic brands, and Alice has already won nearly half of the shares in the computer assembly factory, they will only make core components, and the computer assembly factory will come forward to make the complete printer.

In addition, Yang Dongsheng also thought of 3D printing, a future technology. I don't know if it has a direct connection with traditional printing, or it is only related in a literal sense.

Director Li took out his small notebook and wrote it down carefully.

"What else?"

Director Li flipped the notebook forward, "There is also a piston-type heavy-oil aircraft engine!"

Piston-type heavy oil aircraft engine, the heavy oil here does not refer to the thick and paste-like heavy oil, which can only be used for special boilers equipped with power plants and large ships.

The heavy oil here refers to aviation kerosene and aviation diesel, which are heavier than aviation gasoline.

Piston-type heavy-oil aeroengine technology appeared as early as the 30s. Zeppelin airships use piston-type heavy-oil aeroengines—actually, a diesel engine with reverse propellers.

However, with the emergence of turbojet engines, turbofan engines, and turboprop engines, piston heavy fuel aeroengines have gradually been eliminated due to poor power-to-weight ratios.

But in the past few years, as oil prices have become higher and higher, people have once again thought of piston heavy oil aircraft engines.

In terms of fuel efficiency, turbojet engines are lower than turbofan engines, and turbofan engines are lower than turboprop engines.

Moreover, the fuel consumption of a piston-type heavy-fuel aircraft engine is only half of that of a turboprop engine of the same power.

Developed countries, including the United States, Germany, France, and Austria, have launched research and development of piston-type heavy oil aircraft engines, but the progress is not smooth.

First of all, heavy oil has high viscosity and poor atomization effect, which affects the combustion effect. Without the advantage of thermal efficiency, piston heavy oil aircraft engines are all at a disadvantage compared to turbofan engines and turboprop engines.

Secondly, as the altitude increases, the density and temperature of the air decrease, resulting in a decrease in the amount of air entering the cylinder. Therefore, the piston type heavy oil aircraft engine must be supercharged, and the weight and complexity of the engine suddenly increase.

Third, no more efficient ignition technology has been developed so far.

Fourth, the reliability of piston-type heavy-fuel aircraft engines is too poor. The turbofan engines equipped with modern jet airliners can fly for tens of thousands of hours without maintenance. maintain.

Under the economic crisis, countries have canceled the research and development of piston heavy oil aero-engines one after another.

They recently recruited diesel engine experts from Germany and Austria, many of whom are engaged in piston heavy oil aircraft engines. They were unwilling to give up halfway and proposed this project again.

When this project was deliberated within the company, it caused even greater controversy. Both Europe and the United States failed. Can we do it?
"If Europe and America can't do it, it doesn't mean we can't do it!" Yang Dongsheng said.

If the reliability is poor, then don’t use it to transport people. Yang Dongsheng remembers that in his previous life, the drones in our country first used piston-type heavy oil aeroengines, and the stagnation time was more than doubled.

Through continuous exploration, the reliability will definitely be improved. The turbofan aero engine is not as good as the piston aero engine at the beginning!
Moreover, Europe and the United States have dismounted piston aero engines, because they have advanced turbofans, turboprops, and turboshaft aero engines available, but we do not have them!
Yang Dongsheng realized that doing a good job in the piston heavy fuel aero engine may be an opportunity for them to achieve partial surpassing in the field of aero engines.

"Tell them to pay attention to patent protection, it is not like before!" Yang Dongsheng did not forget to remind.

The country's accession to the WTO is imminent, and strengthening the protection of intellectual property rights is one of our commitments to the WTO.

However, a well-known fashion brand in Spain has made a good demonstration. The fashion brand likes to go to Milan and Paris Fashion Weeks to take back their designs and change them. They make one piece of clothing with two pockets. into four pockets, and then make ready-to-wear sales.

Although the fashion brand has been in constant lawsuits, its business is getting bigger and bigger.

Their main market is domestic, and they face much less pressure than the Spaniards.

When Yang Dongsheng returned home, he discovered that Yang Richu had returned from Europe.

"A few days ago your brother said that you might not come back this summer vacation!" Zhou Ying said.

"I'm coming back to make a documentary this time, and I'll be leaving in two days!" Yang Richu said.

"Do you want me to help you make a documentary?" Yang Dongsheng asked.
