"Already set sail? Everything is going well? Good! You can keep an average speed of fifty or sixty, pay attention to maintain radio contact, so that the base and the rescue ship can find you. Good luck!"

The deputy commander of the navy, Luo Shunchu, established contact with Luo Shunchu according to the set radio frequency after boat No. 34 set sail on the beach of Beidaihe.

Luo Shun first raised his wrist to look at his watch, it was 02:30 in the afternoon.Calculated at a speed of 50 kilometers per hour, they can reach Beidaihe at 05:30.After thinking for a while, Luo Shunchu went back to the house and picked up the phone, "Is the Beidaihe Security Office? I am Luo Shunchu. Between 04:30 and 34:[-] p.m., boat No. [-] will appear in the waters near Beidaihe. Test', please pay attention to the water security team of the security department to identify, the radio call sign is..."

"Minister Tang," Luo Shunchu finished his business and made another call. "Boat No. 34 sailed smoothly and arrived at Beidaihe at 5:[-] p.m. Are you telling them to land on the West Beach?"

Tang Hua: "Yes, West Beach. You can confirm at 04:30. If you can arrive on time without any problems, please call me again."

If Gu Maoxiang and Yun Liang's boat didn't break down, sink, or blow up, and arrived near Beidaihe on time, Tang Hua would be able to call a group of bigwigs out to watch the hovercraft by the sea.

……

The surface of the Bohai Sea.

From Hulushan to Beidaihe, the route is quite simple, just drive straight west.

The white waves around boat No. 34, the jet engine blasts the air under the hovercraft, the rubber apron has been filled, and a large amount of air lifts the hovercraft weighing more than ten tons out of the water, so that the two small propellers behind the boat can push the hovercraft Travel at high speed.

It is rare that today is calm and the sea is the best sea condition for the hovercraft to sail. The propulsion engine of boat No. 34 was turned on to 70% of full power, and the two propulsion engines were turned on to half power. The hovercraft sailed westward at a speed of 55 km/h.

The speed of 55 km/h is 30 knots. In fact, many warships can run at this speed. If the No. 34 boat advances at full speed, it can run at 80-90 km/h. However, this test should not be at full speed, just be safe .

"The voyage has already passed halfway." Yun Liang said.

Gu Maoxiang: "I saw it from the fuel gauge. Look, there is ship 451 ahead. It seems that our route is correct."

Both Yun Liang and Gu Maoxiang saw a small black dot 10 kilometers ahead to their left, which was a naval rescue ship escorting the hovercraft.

"34, 34, please answer if you receive it." The rescue ship was calling boat No. 34.

"I'm boat 34, received."

"Is there an emergency repair? Is a fuel top-up required?"

"Everything is normal on my boat, and the fuel level is normal, thank you."

……

Beidaihe.

As the sun slanted to the west, many people came out from the West Beach and Central Beach, pointing at the No. 34 boat that emerged from the sea in the distance.

Tang Hua saw through the binoculars the No. 34 boat, which was rapidly approaching with splashing water.Although it has entered the visible distance, it still takes 10 minutes to complete these kilometers.

"Actually, this is the second hovercraft built by Harbin Military Industry and Dalian," Tang Hua said. "In August last year, their No. 8 hovercraft completed a long-distance voyage on the water. In April this year, the No. 33 hovercraft was delivered, which is what we saw This one. In the past three months, the No. 34 boat has been tested in various subjects, and it has basically achieved the design purpose.”

The first long voyage of No. 33 boat was nearly a year earlier than the British SR.N1 hovercraft...

The concept design of hovercraft has a history of hundreds of years, but the hovercraft in the modern sense was first designed by Cockerell in the 50s.After completing the preliminary conceptual design, Cockrell published his design as a thesis. The British Saunders-Roy (SR) company felt good and promising after seeing it, and decided to invest in it to support Cockrell.

On the Chinese side, Yun Liang, a military engineer in Kazakhstan, also read Cockerell's paper and thought it was good and promising, so he decided to build a hovercraft for fun.

This is the origin of Chinese and British hovercraft.

1958年8月，33号艇长航成功。1959年，桑德斯-罗伊公司的SR.N1进行了首次发动机运行，6月11日首次试航。7月25日——嗯，也就是六天前，SR.N1完成了首次长航试验。

中国这边，34号艇4月16日首次发动机运行，6月10日进行了100公里长航。这都是第二艘气垫船试验型号了。

Why China's hovercraft is so much earlier than SR.N1, in fact, it is not a black technology, it is China's fast hands.

"Hey, it's docked, it's docked."

Amid the cheers of the people, boat No. 34 approached the coastline, but it did not stop.The rotation speed of the two propellers seemed to be slowing down, but the booster engine was increasing its horsepower. With a roar of "woo-woo-", boat No. 34 rushed to the beach bathing beach on the seashore and onto the beach.

The eyes of the crowd on the beach followed boat 34 and turned around to look back.

Then No. 34 boat still didn’t stop, and the resistance increased when sailing on land. Yun Liang pushed the joystick, and the two propellers increased their horsepower. No. 34 boat continued to drive forward, left the beach, drove onto the hard ground, and headed towards the land. After driving for more than 100 meters, we drove into a parking lot.

Luo Shunchu, Tang Hua, and some comrades from the shipbuilding industry trotted a few steps from the beach to the parking lot.

"Hello, Deputy Commander Luo, and Minister Tang," Gu Maoxiang and Yun Liang jumped off the No. 34 boat, their faces flushed, and they were gasping for breath—it might be the heat of sailing in summer.

"When driving on the ground, the directionality is not very good, drifting left and right," Luo Shunchu said, "Fortunately, the parking lot is empty, otherwise you would have to chat with other cars a few times."

Yun Liang: "Reporting to the commander, there is actually a method of precise control. The propellers on both sides can adjust the speed, and they can also rotate forward and reverse. The hovercraft can move sideways on land... It's just that I haven't practiced the maneuvering skills very well."

Luo Shunchu laughed out loud.

Tang Hua: "How about it, 150 kilometers of continuous sailing, exciting?"

"To tell you the truth, until I reached the finish line, my heart was full of ups and downs." Gu Maoxiang said.

Tang Hua: "Doing scientific research and invention sometimes requires a spirit of self-promotion, showing your achievements to everyone. This is not only a manifestation of confidence in your own scientific research and invention, but also allows people to be familiar with and experience it. The results of the invention, so that in the follow-up research and finalization of mass-produced equipment, we can also get more support."

……

The urgency of developing hovercraft now is no more than when hovercraft was invented in the original historical plane.

At that time, the liberation of Taiwan, Penghu, Jinma, and Mt. was the top priority of the army. Because of this, the hovercraft was highly valued. No matter how difficult the financial and material conditions were, the hovercraft project was always supported.

Now the military's top priority is homeland defense and the coastal sea-air interception system. The sea-air interception system in the middle and offshore seas is almost completed, but there are still enhancements and optimizations. The future plan is to serve the Type 58 destroyer and the Jiangsu-class cruiser. The interception defense circle extends outward by another layer.

The hovercraft project will have great uses in the future, but now to persuade the leaders to continue to invest in research on hovercraft, some publicity methods are needed. If only Tang Hua blablabla tells the chairman, prime minister, and President Peng, it may be a bit reluctant .

After Tang Hua finished talking with Yun Liang and Gu Maoxiang, he looked back, and sure enough Mr. Peng and Ye Shuai were outside the parking lot, staring at boat 34.

"Mr. Peng," Tang Hua said, "The No. 34 air-cushion landing craft jointly developed by the Military Engineering Academy and Dalian Shipyard drove 150 kilometers directly from Hulu Mountain to come here."

"This is an amphibious boat, not bad." Mr. Peng said, "I also thought about it before, if the bottom of the car is sealed, it can be driven into the water, and then a propeller is installed on the rear of the car. It’s an amphibious vehicle. Then I saw the amphibious tank, and I realized that someone had invented this thing long ago.”

Tang Hua: "Mr. Peng, in fact, boat No. 34 is mainly a ship. If it reaches the ground, the ground must be relatively flat."

Mr. Peng nodded: "I can see that its rubber sole has been rubbing against the ground."

Tang Hua: "This hovercraft is actually not compared with an amphibious vehicle. It is first a speedboat that can run faster than any speedboat, and its amphibious property is second. As a landing craft, it can quickly pass through defenses. As a transport ship, it can deliver supplies to poor islands with no dock facilities.”

Chapter 229, Light Nuclear Reactor Group Established

Mr. Peng and Ye Shuai came out to see the hovercraft because the daytime meeting was over.

After a while, Tang Hua saw Deng Shuai and Su Yu walking side by side.

"Thank you, Political Commissar Deng, thank you." Su Yu said in a low voice.

Deng Shuai didn't say anything, just patted Suyu's upper arm, neither of them stopped to look at boat 34, and continued to walk away.

"Boss Peng, what was discussed in today's meeting?" Tang Hua asked.

Mr. Peng just coughed.
