"Those are various modifications of the Type 037 hunting submarine. ”

The Chinese entourage had long been instructed by their superiors to cooperate with the Sichuan East Plant in the inspection of the chief of staff of the Bangladesh Navy.

Ibri Khan only knew that the Type 037 hunting submarine was an old model copied from Soviet equipment, where had he heard of any improvements, and even if he was interested.

I walked to a model and carefully looked at the details on it, but I didn't see anything new from the model in front of me for a long time, it was still a twin 57mm naval gun, a twin 30mm anti-aircraft gun, an anti-submarine rocket launcher that had not changed for thousands of years, and a depth charge delivery device, so I didn't see any difference.

However, just as Ibri Khan shook his head secretly, about to look at the next model, the adjutant next to him suddenly whispered something to him, and then pointed to the bottom of the model.

Don't look at Bangladesh as a poor country, but most of their officers have studied in naval academies in Europe and the United States, and their knowledge is not low, such as Ibri Khan, who studied in Britain and France in the early years, and came into contact with a large number of advanced naval equipment, including the waterjet propulsion on the model in front of him.

I remember that when he first saw this kind of artifact that can make missile boats have a speed of 43 knots in France, he was stunned, he thought that this kind of device could only be possessed by developed countries, but he didn't expect that he could see this kind of thing in China, and it was installed on the Type 307 hunting submarine ordered by Bangladesh, how could he not be surprised?

So before the Chinese entourage could answer, Ibri Khan asked again: "Is this really a waterjet propulsion?"

"Yes, General Ibri Khan, this is the waterjet!"

The Chinese escort nodded, and then pulled a young man from the side, and introduced with a smile: "This is the person in charge of the Chuandong Factory, Meng Jianye, and he will introduce the specific situation to you." ”

Ibrihan looked at the well-proportioned, ordinary-looking young man and didn't say much, but pointed to the model next to him and asked, "Do you have the ability to produce waterjets?"

This is a very straightforward question, but Ibri Khan has to be so straightforward, because in his eyes, the waterjet propulsion thing is still very high, although he is not clear about the principle of opposites, but only a few countries in the world, such as Europe, the United States, and the Soviet Union, have the ability to manufacture such devices.

As for China, Ibri Khan didn't expect that there was a record of similar devices and equipment, so he had to ask such a question, after all, there are too many people in the world who dare to blow cowhide into the sky.

Meng Jianye did not explain much about this, but suggested: "Now the test of a new type of waterjet propulsion is being carried out in the river bay outside the factory, and General Ibri Khan can follow me to see if he is interested." ”

As soon as he heard this, Ibri Khan's eyes suddenly lit up, and he immediately nodded: "Yes!"

……

A dinghy with a displacement of about 100 tons is driving at high speed in a gentle river bay, but unlike the previous dinghy, the wake behind the running dinghy is not obvious, coupled with the speed much higher than that of the same type of dinghy, it is obvious that the transmission of this moving dinghy has been improved.

And this is the only waterjet propulsion device test boat in the East Sichuan Plant, Xiaohewan.

"Our Sichuan East Plant from the early 60s to build the factory has been committed to the research of water jet propulsion device, after more than 20 years of development, the formation of four series, more than 10 models of huge system, you just saw the model on the water jet propulsion device, is our latest model PS-6A water jet propulsion device, using a new generation of double-suction centrifugal pump and a new alloy duct blade, with the French Piertic company of high-speed diesel engine, can easily make the 037 type hunting submarine speed up to 35 knots......"

Standing in front of the berth of the test wharf, Meng Jianye pointed to the Xiaohewan that was driving in the river bay and talked to Ibri Khan, listening to Ibri Khan nodding again and again, and asking two specific questions from time to time, Meng Jianye did not hesitate to give a very appropriate answer.

This made Ibri Khan a little excited, because he really didn't expect that China really had such advanced good things.

However, it was not only Ibri Khan who was also excited, Xue Qiang was also one of them, because he really didn't expect that the old project, which had been off for five or six years, would come back to life again in this form.

Yes, the waterjet propulsion is indeed an old project, not only that, but the implementation units of this project are the current Sichuan East Plant and Xiangxi Plant.

In the 60s, the East Sichuan Plant and the Xiangxi Plant were the key factories of the third-line construction at that time, which gathered the essence of many submarines in China at that time, among which there was a pump pushing research group separated from Harbin Institute of Technology, which was merged into the East Sichuan Plant at that time.

The reason for this arrangement is that the ultimate goal of the pump propulsion system is to innovate the submarine propulsion system, because compared with the traditional propeller, the cavitation of the pump propulsion system is almost negligible, the noise is less, the mechanical structure is simpler, and the propulsion efficiency is higher, which can be said to represent the future direction of the submarine propulsion system.

Originally, it was planned that this research group would be merged into the Ship Thrust Research Institute, but because Sino-Soviet relations were tense and war broke out at any time, the higher authorities temporarily decided to move it to the third-line area inland, so that they could continue this research with great potential after the outbreak of war.

In this way, the pump pushing research group was able to settle in the East Sichuan plant, carried out research on related disciplines in an extremely difficult environment, and achieved a series of results.

However, before these achievements could be applied, the turbulence of the special period completely interrupted the research process, and those experts and technicians who participated in the development were knocked down and transferred, and the projects that had been good for several years of hard work were dismantled.

When the special period ended, the superiors came to see that the whole project had long been out of shape, and if they wanted to recover, they would have to invest a lot of money.

At that time, Xue Qiang, who was the person in charge of this project, fought with his superiors very much, and the result can be imagined, naturally he hit his head and broke the bloodstream, and there was no way that so many projects that had achieved initial results were cut, and how could such a project as a pump push system that did not even have a result be special?

Faced with such an ending, Xue Qiang can be said to be angry, and because of this, he did not transfer out according to the wishes of his superiors, but stayed in Xiangxi Factory, because here is not only his youth and sweat, but also the hard work of nearly 20 years.
