Chapter 636 Aero Engines

Seeing Yang Dongsheng's gaze, Vice President Wang said, "There is something I want to report to you!"

"Go to my office!" Yang Dongsheng looked around.

The service staff stood at the door, waiting to clean the conference room, but seeing that they were still in the conference room, they dared not come in.

The two entered Yang Dongsheng's office. Today's weather is fine, with no clouds in the sky and a clear blue sky. The adjacent Huangpu River seems to flow under your feet.

Tea was served in the secretary's room.

"Be careful about the piston-type heavy-oil aircraft engine! Whether Dongsheng Foods will be profitable in the future depends on the piston-type heavy-oil aircraft engine!" Yang Dongsheng said.

The land of Dongsheng Food has spread all over the country in more than [-] provinces and cities.

Moreover, Yang Dongsheng has not gone to Fujian, Guangxi, and E provinces in the central and eastern provinces, and the vast Xinjiang, Tibet, Gansu, and Qing provinces in the west. The area will definitely be larger in the future.

Yang Dongsheng has an e-commerce company in his hand, so he doesn't worry about sales, but transportation will definitely be the number one problem that Dongsheng Foods will face in the future.

The transportation of agricultural products must not only pay attention to cost, but also need to pay attention to timeliness.

Many vegetables and fruits have to be picked and delivered before they are fully ripe, which seriously affects the yield and quality. Not to mention, a large number of agricultural products will still be spoiled and lost during transportation.

There are also ways to deal with it, that is, air transportation and refrigerated transportation, but whether it is air transportation or refrigerated transportation, the cost is too high, and most agricultural products are not worth such transportation.

It wasn't until the appearance of the piston-type heavy oil aircraft engine that Yang Dongsheng's eyes lit up.

Yang Dongsheng's plan is to use piston-type heavy oil aircraft engines to create a drone transport fleet.

The fuel efficiency of piston aircraft engines is much higher than that of turbofans, turboshafts, and turboprops, and heavy fuel is much cheaper than aviation gasoline.

The unmanned aircraft is off the ground, there is no friction from the road, and the complicated manual operation mechanism is removed, which greatly improves the transportation efficiency.

Another advantage of airplanes over land vehicles is that the temperature at high altitudes is low, which is conducive to the preservation of agricultural products and can save a lot of cooling costs.

And you don’t have to pay tolls!
Yang Dongsheng did some calculations, and the final transportation cost of an unmanned aircraft using a piston-type heavy fuel aeroengine will be much lower than that of a truck.

These are the reasons why Yang Dongsheng dared to let go and let Dongsheng Food spread across the country.

"I've been keeping an eye on the matter over there. The people from Germany and Austria are still working hard! But the heavy fuel aircraft engine is a new thing. It may take about ten years for this thing to mature! If the company wants to make an aircraft engine, I I have a suggestion!" Vice President Wang put down his teacup and said.

"Tell me!" Yang Dongsheng picked up the teacup and blew on the tea leaves.

Even though Yang Dongsheng learned from Temasek and implemented a deferred incentive and callback mechanism in the company, the vice presidents are still accustomed to pulling business hard on their own plates.

"The company is making gas turbines. You know that gas turbines and turbofan engines are common in many aspects. General Electric and Rolls-Royce are not only gas turbine giants, but also turbofan engine giants. The company recruited these people Many of them are made of turbofan engines!"

The 911/[-] incident hit global stock markets, but the airline industry has had the greatest impact.

Companies such as General Electric, Rolls-Royce, Pratt & Whitney, Honeywell, and Safran have all laid off staff substantially, and Rolls-Royce alone has laid off nearly 5000 people.

"You want to make a turbofan engine?" Yang Dongsheng put down his teacup, "Have you ever thought that even if we can make a turbofan aircraft engine, will the FAA give us an airworthiness certificate? Without an airworthiness certificate, who would buy it? Our engine?"

Vice President Wang did not directly answer Yang Dongsheng's question, "I went to Chang'an recently, and we successfully forged the first main beam of a large transport aircraft for the 7.5-ton die forging press manufactured by Chang'an Aircraft Manufacturing Plant, but I heard that the matching The progress of the turbofan engine project is very unsatisfactory, and recently I have to consider buying engines from Russia!"

In the previous life, our country ordered the Il-76 transport aircraft from Russia, but Russia overestimated itself. They no longer have the ability to manufacture the Il-76 transport aircraft alone, and finally had to give us a batch of D-30 aero engines to offset the debt.

Later, we gritted our teeth and built a large transport aircraft by ourselves, so these engines were used on the Yun-20.

The D-30 series engine is a turbofan engine designed by the Soviet Union in the 60s. The bypass ratio is only 2.4, which can only be regarded as a medium bypass ratio engine.

The too small bypass ratio leads to high fuel consumption and low thrust of the D-30 series engines, and the Y-20 cannot reach the designed maximum transportation capacity at all.

The American C-20 transport aircraft of the same level as the Yun-17 uses a Pratt & Whitney PW-2040 engine with a bypass ratio of 5.9, which looks thicker than the D-30.

The C-17 far exceeds the Yun-20 in terms of load and range.

Although our country did not order the Il-76 in this life, and the large transport aircraft project was launched several years earlier than in the previous life, we still had to buy engines from Russia in the end.

The meaning of Vice President Wang is obvious, military transport aircraft engines do not need to obtain an airworthiness certificate from the FAA.

If our country can accept old Russian antiques, there is no reason why they cannot accept aero-engines made by domestic companies. Even if they can only manufacture an aero-engine as backward as the D-30, they can still win in the competition with Russia , because at least you don't want to spend foreign exchange to buy these engines.

Vice President Wang saw that Yang Dongsheng had already been convinced by him, and continued, "I know that the company must now concentrate on the development of semiconductors, and Dongsheng Heavy Industry must achieve a balance of payments! In fact, manufacturing turbofan engines does not need to be completely new, and many equipment can be compared with gas turbines. Shared. I have calculated according to the internationally unified price. As long as we can sell 300 engines, we can recover the cost. I have received definite news that we will produce more than 200 of this large transport aircraft, and one aircraft needs to be equipped with four engine. I heard that the country is planning to launch a large civil airliner!"

"You come up with a plan as soon as possible!" Yang Dongsheng said.

On New Year's Eve, Yang Dongsheng took a flight to Huajing, and then rushed back to Shanghai early in the morning to celebrate the New Year.
