Since the launch of the 10,000-ton hydraulic press, this is imperative in all aspects, and now it is sure to be launched, everyone must be happy.

Yang Hui is the only one who is thinking about how to get this 10,000-ton hydraulic press on the ground and how to make up this amount of money? Now if you want the state to set up a project to engage in this kind of thing, you will know that it is unrealistic at a glance, and the big press is not only a hydraulic press that needs to be built urgently, but also the old 30,000-ton hydraulic press can no longer meet the demand.

Perhaps, we have to think of a way, and we have to fight for other ways to build these things as soon as possible, and the current hydraulic press!

After thinking about it, it is still the Southwest Science and Industry to take the lead in funding, this year the Southwest Science and Industry relied on the policy preferences given by the chief designer Deng in 83 years, and quickly developed and expanded. After so many years, after the new generation of 386 came to power, a group of people have shouted to take back the preferential policies given to Southwest Science and Industry.

It's right to think about it, after all, the southwest science and industry has been too popular for a few years, a large amount of foreign exchange earnings but not handed over to the state, people must have people who are dissatisfied, red-eyed, and now the national finance is all kinds of depletion, before the implementation of the tax system, the southwest science and industry is really a piece of oil bun!

Now, if Southwest Science and Industry proposes to fund the development of the country's supporting large hydraulic press project, there will be an excuse to say: I have great ability, but the responsibility is also great, you see how many projects I have undertaken that were originally funded by the country.

This should also be regarded as some of the benefits that come with participating in this project, of course, it is definitely not enough for the Southwest Science and Industry family to pay this money.

We have to pull together the Southwest Aluminum, which was originally responsible for forging turbine discs, so that it should be possible to build this thing, and the aluminum industry is even more profitable than the steel industry in these years.

I believe that as long as it is time to put the huge market out, and then Southwest Science and Industry said that it will also invest half of the funds. This project should be a smooth ride.

At least after this thing is built, it is definitely a great political achievement, and this kind of project that can break through the domestic shortcomings is absolutely irresistible for the leaders of resource-based state-owned enterprises.

"Well, we've now identified improvements to the core machine. It is believed that after the completion of the core machine improvement, it will be a great improvement in reliability and economy for CG2000. ”

Yang Hui now does not plan to continue to toss too much in the core machine, Ya is only to improve the total temperature of the combustion chamber and high-temperature turbine, which has led to such a large supporting project, I dare not want to go on like this, 624 around the core machine project, there are still many "pits" waiting for Southwest Science and Industry to jump.

Mr. Wen has been enduring it for a long time now, and he has improved the core machine just now. He also knew that it was indeed necessary, but these improvements would not be of much benefit to the promotion!

"That's all right, the improvement of the core machine can be done according to the agreed plan, what we need to talk about now is how to add 2 tons of thrust to the CG2000, and it is definitely not enough to change the core machine alone."

These words are loud and thought-provoking, giving people a sense of empowerment.

The deputy chief designer of the Ivchenko Design Bureau, who sat on the side and rarely spoke, had an approving expression to indicate that it was time to increase the push. It is necessary to make improvements in the low-pressure rotor section.

And when it comes to improving the low-pressure compressor part, this time finally gives MTU the opportunity to appear. It's what they're good at!

"No problem, this is definitely no problem at all, even if the current core machine is not changed, our MTU can still improve the low-pressure compressor through Guò to achieve the increase of the CG2000 engine."

Finally found a sense of storage in front of these predators, and MTU was out of control. Directly gave their improvement plan to.

"Previously, the low-pressure compressor we designed for the CG2000 was a three-stage low-pressure compressor and a four-stage low-pressure turbine, but now in order to increase the thrust, we have chosen to add one stage to each of the compressor and the turbine."

After listening to this plan, everyone agrees that the series improvement of the large signal channel ratio turbofan engine is being improved. Increasing the number of stages of low-pressure compressors and low-pressure turbines is a very common scheme, and it is impossible not to start from this aspect if we want to make a significant increase and improvement.

As the chief designer of the model, Mr. Wen knew the whole project very well, and after a rough evaluation of the effect of this improvement plan, he was still sad.

"The plan provided by MTU is indeed very feasible, and we should be able to add about a ton to the engine through the overhaul of the low-pressure rotor and the small overhaul of the core engine, but to achieve the final goal, we have to continue to think about the plan."

Originally, it was a design standard of 7.5 tons, but the CG2000 has reached a maximum thrust of 7.8 tons in the previous test, and if the current improvement can increase the thrust by one ton, 8.8 or 9 tons should be achievable in the middle.

If some improvements are made to the fan, continue to optimize the gear reducer system, so that the performance of the external channel fan is increased, and the engine finally breaks through 9 tons, reaching 9.1 or 9.2 tons should not be a problem.

From this point of view, it seems that it can be barely enough if it is installed in the subsequent modification of the MPC, of course, this is provided that some additional equipment that does not have much necessary needs needs to be eliminated in the subsequent aircraft improvements.

For example, things like the tail friction system of the first flight of Zhonggong not long ago should have to be removed, and the internal section of the 3.4-meter fuselage of the MPC series is relatively narrow, and the outer section of the entire fuselage should also be slightly slimmer, so the drag coefficient can also be optimized.

In this way, as long as the subsequent MPC improved version does not fly on the plateau route, the most normal three-level cockpit layout should be able to reach 110 passengers like the Boeing 737-600, and the maximum passenger capacity of 130 people can even be reached with a high-density layout.

It has to be said that such an improvement is still acceptable, but this kind of high-density layout can only reach a capacity of 130 passengers, can it fully meet the needs of the Republic and even the international market after 2000?

I'm afraid this is far from enough, the high-density cockpit layout of 130 people is only the level of the Airbus A319.

"Such an improvement can indeed be said in the past, for the development of 110-130 seats MPC75 follow-up model can meet the needs, I think it will be improved according to this scheme!"

For the current situation, although it does not meet the required increase of two tons of thrust to reach between 9.5 and 10 tons, it is actually enough, at least Yang Hui himself is relatively satisfied.

However, when the box of additional thrust was opened, how could the thrust increase to 9.2 tons be enough, Wen always stood up and shouted now.

In the narrow-body passenger aircraft market after 2000, the majority of the airliners have always been Airbus A320-200 and Boeing 737-700/800 passenger aircraft, which have 150 people in the ordinary layout and even 180 in the high-density layout.

Almost knocking on the table, Chief Engineer Wen said bluntly: "If you want to confront the A320 and B737 series aircraft head-on, the MPC must have a model of 150-180 seats, and our supporting CG2000 must also be increased to about 12 tons." (To be continued.) )
