The sheer size of this research institute shocked these bumpkins.

Now, the atmosphere is very friendly, and the other party wants to see the prototype, so of course there is nothing to refuse.

"What you are seeing now is our most advanced marine gas turbine." Leading everyone to the test area, Popov pointed to one of the large machines and said: "Its model is called GTD, and it is an axial flow three-axis

The gas turbine has a power of 20 megawatts. We started developing it in 1971 and successfully developed it in 1984. Currently, it has been equipped on many warships including the Slava-class cruiser, and it is the pride of our Soviet Union."

Lao Maozi owns the Kirov-class nuclear-powered cruiser, but it is too expensive and they cannot afford it, so they built a scaled-down version of the conventionally powered cruiser Glorious-class. Several of the ships produced in the later period were equipped with four GTDs as

For acceleration power, there are two early models as cruising power, full-combustion power, which is quite advanced.

At this time, everyone was looking at this prototype. It had a cylindrical front end and a cubic structure at the back. It showed the rough style of Lao Maozi. Wu Shengli couldn't help but ask: "What kind of aero engine is this engine?"

Improved?"

Qin Tao wanted to stop him, but it was too late. Zhao Ling quickly translated Wu Shengli's question.

Qin Tao could only put his hand on his forehead, which was embarrassing.

"No, no, our gas turbines are different from aero engines. In the 1950s, when we started to develop gas turbines, we found that Western gas turbines improved by aero engines were very inappropriate. After all, there are significant differences between the two.

, Therefore, we had to develop specialized gas turbines, and our design bureau was established at that time." Popov said.

Except for Lao Maozi, other countries use aviation engines to improve them. Take the most famous LM2500 gas turbine as an example, which is improved by the famous TF39 turbofan engine.

"Yes, lifespan is the biggest problem." In order to save some face for Wu Shengli, Qin Tao could only take over the conversation and said.

Other countries can make changes, but Lao Maozi can't because their engine life is too short! Even the Su-27 I saw a few days ago uses an AL-31F engine with a lifespan of only three hundred hours.

If this is used on a warship, the engine will need to be overhauled before it goes very far.

"Yes, this is one problem, and there are other problems. In short, we are taking the path of specialized research and development." Popov said: "We also have to consider the needs of the navy, for example, in order to withstand underwater explosions

, the shock wave generated when a bomb or torpedo hits, our gas turbine is designed to withstand an explosion vibration impact of 41G, which is the highest impact resistance of current naval gas turbines. How much explosion vibration impact can the LM2500 you imported from the United States withstand?"

The other party's rhetorical question made the people present unable to answer. After all, the people who came were mainly leaders and their assistants, etc. They were just here to make soy sauce, and they did not have much technical knowledge reserves.

"American gas turbines can only withstand a 15G explosion impact." Qin Tao answered immediately. He couldn't let these people be stumped.

The LM2500 is improved from a jet engine. A jet may disintegrate if it exceeds an overload of 10G. The vibration of 15G is enough, but as a power for the navy, it is obviously not enough.

Hearing what Qin Tao said, Popov showed a proud smile on his face. Just before he showed off, Qin Tao continued: "However, American gas turbines are installed on a special base.

This base can withstand an impact of 200G."

It is obviously unrealistic to rely on the gas turbine itself to withstand the shock wave. Therefore, the Americans simply use a special base to solve the problem, so that the needs of warships can be met.

The smile on Popov's face froze.

"Well, it's getting late. Popov, is it time for dinner in your canteen?" Nikolay said.

Nicholas came with guests from the East, so of course he couldn't neglect it. After this inspection, the whole afternoon had passed. Next, of course, it was time to continue eating and drinking.

"Yes, everyone come with me." Popov said.
