Chapter 581: Spey changes the gas turbine

"Yes." "Some of this capital may be in the name of some Western companies, but we actually control it behind it, and we can fully raise the cost of building the oil pipeline, and now in our country, we have built the oil pipeline from Karachi to Islamabad, so we just need to continue to build on the original pipeline, along the railway line, to Lhasa in your country, and that's fine," Mhammad said. ”

Repair to Lhasa! Mhammad did not put forward more demands, such as repairing to the eastern part of China, after all, the eastern part is an economically developed area, and the current Tibet region is still very backward.

As long as it is repaired to Lhasa, Huaxia will see the benefits in the future, and will build it again, all the way to the east, isn't this how the west-to-east gas transmission is made, Mhammad only needs to build Lhasa, so that there is no need to worry too much about the Huaxia side, and Mhammad estimates that within five years, the cost will definitely be recovered, and the future will be net profit.

"Okay." Deng Gong said in a word: "Then let's continue our previous cooperation and jointly build this oil pipeline!" We both invest 50 percent, and the profit is 55 percent. ”

Unconsciously, Mhammad negotiated a cooperation project again, and he was also very happy in his heart.

Continuing with the economic side of the talks, the two sides strengthened cooperation to achieve a win-win situation, and then moved on to the military aspect.

"We are also very shocked by the progress of Pakistan in the military industry, especially now that Pakistan has successfully developed the Shield of Friendship." Defense Minister General Qin said: "The problem of air defense of the fleet, which has been plaguing us, can be effectively solved, and we have planned to build two warships equipped with the Shield of Friendship to increase the air defense capability of the Navy." ”

Now, friction in the South China Sea still exists, and China has a long coastline. There are important maritime interests to protect, warships that need to have a complete air defense system, Luhu-class destroyers, but only solve the problem of point air defense, and regional air defense capabilities are still provided by the Shield of Friendship.

"yes." "We also plan for the Shield of Friendship when it matures," Mhammad said. Work began on the construction of several specialized air defense destroyers. However, how do you plan to solve the power problem used by your warships? ”

Huaxia's two Luhu-class ships use LM2500 gas turbines imported from the United States, which are excellent warship power, and most of the warships in the United States use this power system, but the honeymoon period between China and the West has ended. The West will no longer hand over this excellent power system to Huaxia.

"Yes, that's a problem for us, and if we can't do it, we'll have to use the original steam turbine." Central Military Commission, Navy Commander General Zhang said.

For the navy, equipment plays a major role, and the equipment of warships is the power system. Also a big problem.

Almost from armored warships, the power of warships was a steam engine. After that, it was turned into a steam turbine, which improved thermal efficiency and propelled huge warships to reach speeds of about thirty knots, until now. The brigade-class warships in China, and even the modern-class destroyers of the Soviets, still use steam turbines.

The power is reliable, durable, and the cost of equipment and use is low. These are its advantages, but its disadvantage is that it is slow! Before use, the boiler must be burned and the water pressure is increased enough before it can be started.

In contrast, the gas turbine is very fast, no matter when, after starting, it can run at full power almost immediately, with good acceleration performance and high power density.

The technical capabilities of Huaxia are limited, and the two Luhu-class ships use LM2500 gas turbines imported from the United States, while in history, the 167 Shenzhen ship built later was replaced with a steam turbine, which also led to the 167 ship being decommissioned in a hurry after more than ten years of service, and was dismantled on the slipway, almost leaving a shell.

"I have an offer." "You can build a gas turbine for ships based on the Spey engine," Mhammad said. We in Pakistan also have a demand for marine power, and if the transformation can be successful, our follow-up warships can also use this engine. ”

Change! Almost all gas turbines are modified from aero engines, such as the famous LM2500, which is based on the TF39 engine used in the C5 transport aircraft, and the "Olympus" naval gas turbine, the main force of the British, was originally developed as a turbojet engine for the "Vulcan" strategic bomber, and then it was improved, and finally brilliant.

At the beginning, the Tu-16 bomber of the Soviets was introduced, and after the localization of the H-6, the engine used on the Tu-16 was also copied, named the turbojet-8 engine. The air flow and maximum thrust of this engine are comparable to those of the "Olympus" turbojet engine, but the thrust-to-weight ratio is lower and the fuel consumption rate is higher. Scientists in Huaxia have made more than 80 modifications to the engine to adapt to the harsh environment of the ship's operation at sea, newly designed the power turbine for power output, and redesigned the accessories and various systems according to the environment used on the ship. In 74, the "Turbojet-8 modification" type ship gas turbine completed the durability test and was ready to transfer to the equipment production stage. As a result, the British came in and recommended their "Olympus" shipboard gas turbine to Huaxia, and forcefully stirred up the turbojet-8 to change the ship's gas turbine, and the British's "Olympus" did not open the market, and was given a head start by the American LM2500 gas turbine.

This history is painful, in short, Huaxia still does not have a suitable marine gas turbine, and after the sanctions imposed on China by the Western world led by the United States, Huaxia found that it did not have a suitable gas turbine to use.

However, unlike history, under the intervention of Mahmad, the Spey engine was finally successfully imitated by Huaxia, and began to be officially installed, becoming a key model of engine in Huaxia.

At the same time, Mhamad also knows that it is okay to improve the Spey engine into a marine gas turbine, because the British are already doing it!

The British's Spey SM1A gas turbine, that is, the model directly improved from Spey, has a maximum power of 13,824 kilowatts and a fuel consumption rate of 235g per kilowatt hour, and then improved into the C type, the maximum power has been increased to 17,750 kilowatts, and the fuel consumption rate has been reduced to 230g, while the Americans' LM2500 gas turbine, the power of the initial model, is 18,755 kilowatts, which has reached almost the same power as the Americans' LM2500 gas turbine.

In later generations, the islanders were very satisfied with this gas turbine and used it on their own high-wave destroyers.

And now, Huaxia has mastered the full set of technology of Spey, and on the basis of Spey, it has come up with a more powerful TF41 engine, and is still studying the further increase of this engine, the thrust can be further expanded, so this engine, if it is improved into a gas turbine, it should reach the same power as the British gas turbine, or even higher, and the new compressor is used, and the temperature is raised, and it is expected to reach more than 20,000 kilowatts in the end. The Americans' LM2500 gas turbine has been continuously improved to increase its final power by 2 times.

Two such marine gas turbines are enough to propel a 4,000-ton destroyer, and four can push a destroyer of more than 7,000 tons, which can fully meet the requirements of a new destroyer, and in Mhammad's plan, the displacement of Pakistan's Shield of Friendship warship is about 8,000 tons.

Remodel Spey! After Spey's success in improving it into shipboard power, it is also possible to learn from the experience and improve the more advanced F110 engines now produced in Pakistan to become marine power, and if the F110 engine is successfully modified, four cruisers capable of driving more than 10,000 tons.

Of course, this is all a plan for the future, and the main plan now is to improve Spey!

Hearing Mhammad's proposal, Navy Commander General Zhang looked at Mhammad with great admiration and said: "President Mhammad, your proposal is very good, we can consider setting up a project and developing a qualified gas turbine as soon as possible." ”

Through this US sanction and the end of the honeymoon period with the West, Huaxia has finally learned a lesson, it must rely on itself! The West is unreliable!

"After the heart of our big drive is solved, the main air defense system has also been solved, and our new destroyers will definitely be able to be manufactured smoothly and quickly form combat effectiveness, so that they can escort our future aircraft carrier formation." General Zhang said.

Aircraft carrier formations! China has a long period of maritime rights and interests to protect, and naturally it also needs an aircraft carrier formation, but because of the country's limited financial resources, it is not possible to start construction for the time being, but the relevant arguments have been carried out.

In the past, the air defense performance of destroyers limited to the country was limited, and even if an aircraft carrier was built, there were no air defense destroyers to protect it, but now, with the solution of the air defense problem, it is finally possible to have an escort ship of an aircraft carrier.

"yes. With this Friendship Shield system of ours, the problem of air defense is finally solved. "We are now arguing in the Navy and preparing to build our own second aircraft carrier, I wonder if your country is interested in participating in it?" (To be continued......)
