Siheyuan: I eat melons while doing scientific research

Chapter 1149: The Dispute between Three and Four
From the location where the fleet conducts exercises and marine scientific research, it is less than 200 kilometers away from Quoc Ngong Island. At the fleet's speed of 25 knots, it is about four hours.

This speed is achieved by sacrificing half of the combat effectiveness of a frigate. There are landing craft, but it is very difficult for them to keep up with the destroyers and guided boats, which will affect the maneuverability of the formation.

For this purpose, a frigate was specially used to unload a large amount of ammunition in order to load scientific research personnel and equipment materials, especially the torpedoes, which were completely unloaded.

Fortunately, we can now afford to sacrifice the combat effectiveness of this frigate. It is still very cost-effective to exchange the combat effectiveness of half a frigate for a speed of 25 knots.

Just four hours later, the fleet had approached the target island.

There is more than one island in the target sea area, but our primary target is naturally the largest one. Under the moonlight, that island looks like a huge mountain, standing in front of the nearby formation.

The terrain of this island is special and relatively steep. Looking at it in the night, it is as dark as a wall stretching in front of the comrades, with only a faint white moonlight shining from the ridge.

"Everything is normal in the air and at sea!"

The voice of the Tu-4 special comrade came from the formation commander's radio.

The combat aircraft in the sky had been replaced a long time ago, but the Tu-4 special aircraft was still patrolling in the sky. If the electronic reconnaissance ship was responsible for the air and sea situation support in the direction of Angelica, then the Tu-4 special aircraft was responsible for the air and sea support in the east of Quoc Kong Island.

"The scientific expedition team understands!" The commander put down the microphone used to communicate with the Tu-4 and picked up another microphone next to him that was used to command the team.

"The marine meteorological and hydrological observation work in the waters of Guogong Island begins now!"

Planes circled in the air, making a faint roar in the quiet night sky, while the sea was even more lively. Amid the "da da da da" sound of diesel engines, four guide boats dispersed and patrolled at a low speed at a certain distance around.

Guarding with swords, this is the mission of these four escort boats.

They have to deal with possible low-intensity conflicts, and be responsible for anti-ship missions in high-intensity conflicts, while providing a little air defense cover for the two large ships.

Speaking of this, the two large ships felt very aggrieved.

The destroyer is the commander of the entire mission. At the same time, it is large in size but strong in weight. Although the radar technology installed on it is not advanced, it has enough power and can see farther than the one on the escort boat. It can be regarded as a supplement to the air and sea support of the Tu-4T in the air.

After all, the radar on the escort boat is designed for anti-ship missiles and artillery, but when it comes to advanced technology, it's really not their turn. Pulse PD and the like are not yet their turn to install. However, the destroyer that looks like a weakling now will definitely be equipped with them when it is modified.

The frigate's job was much simpler. It was now lowering a small boat to prepare for the transfer of personnel and supplies.

At the same time, small boats were being lowered from the destroyer, and the small boats on the two large ships were used together to try to build the meteorological observation station on Koh Kong Island as quickly as possible.

Several small boats rushed towards the island shore that had been selected long ago. This was the north shore of the island. Compared with the south shore, the terrain was flatter, and there were freshwater streams in the east, middle and west. The place where the comrades went to the island at this time was in the middle and east of the island. The flat area here was relatively large, and there was a stream.

Another group of comrades are on the island in the middle part, where there is also a stream.

Of these two streams, the middle one leads to the highest peak of the island, while the eastern one leads to the second highest peak of the island. Although they are called peaks, they are actually only about 300 meters high. There are just dense vegetation and no roads, so it is relatively easier to go up along the stream and it is not easy to get lost.

The comrades set up camp near the mouth of the two streams. Several tents were pitched and some of them began to rest. They had a heavy task during the day and climbing under primitive vegetation was difficult.

Another group of comrades used the equipment and materials delivered by small boats to start building an automatic hydrological and meteorological station above the high tide line.

Several pressure water level gauges with temperature measurement were laid along the aluminum alloy pipes into the sea. This work could not be completed in one night. So many gauges were installed to ensure that at least one could be used. After all, this thing is under salt water and the working environment is relatively harsh.

We are serious about scientific observation.

However, the main body of the automatic hydrological and meteorological station was repaired very quickly.

The comrades brought quick-drying cement, steel bars, reinforced concrete precast panels and other materials. They arrived at around 2 a.m., and by eight a.m., an automatic hydrological and meteorological station of about four square meters had been set up on the island.

Wind speed, wind direction and rainfall monitoring equipment are installed on the top of the weather station. In the louvered box next to it, the air thermometer and humidity meter are working quietly. There are also several wires installed in the waterproof junction box, waiting for the wires of the pressure water level thermometer to be laid out.

"The hydrological and meteorological station has been basically set up, and the surveying and mapping comrades are launching an attack on the two peaks on the island." The destroyer, serving as the command ship, received a report from comrades on the island. This news was also sent from the destroyer to the Tu-4T, from the Tu-4T to the electronic reconnaissance ship, and then from the electronic reconnaissance ship all the way back to the command center in the capital.

"Very good, comrades, you have worked hard. I hope you will continue to work hard and successfully complete the scientific observation and observatory station construction tasks." The command center's words were transmitted back to the command ship along the invisible electromagnetic waves, and then to the ears of the comrades who were working hard on the island. Even the two surveying and mapping teams that had set out at 7 a.m. received praise and congratulations from the capital.

Some comrades are taking advantage of this opportunity to collect specimens of plant and animal resources on the island.

"Oh my god, great food! Everyone will have a great lunch at noon~~~~~" One comrade's Mandarin was very difficult to understand, but the comrades still understood it.

"Fuck, are you here to collect specimens or to be a cook?" a comrade laughed.

"It's all the same. There are so many grouper fish in here, let's sprinkle some water~~~~"

The comrades all laughed.

At this time, the comrades of the surveying and mapping group were trekking through mountains and rivers, heading towards the two main peaks. They were going to bury two surveying and mapping level marks at the highest point and mark the elevations of the two level marks for use by later comrades in surveying and mapping.

Generally, when this kind of level mark is buried, the location, elevation, burial time and other information will be recorded.

Well, everything is for scientific research and observation.

Some comrades who had completed their mission retreated to the frigate in a small boat. The frigate took them to the northeast of Koh Kong Island. Two of the four frigates were separated and followed them. There was also an island there, but it was smaller.

Comrades in the waters of Guogong Island were busy as hell. In Beijing, at nine o'clock in the morning, the second day of the air superiority fighter program demonstration meeting also began.

"Comrades, you all must have worked hard last night, right?" The leader of the Defense Work Committee began by expressing his condolences at the beginning of the meeting.

"It's not hard and it's quite interesting." Similar words are heard frequently.

"Well, let's discuss today whether options 3 and 4 can be used, or whether we should play it safe and choose option 2. We can discuss the rest after this decision is made." The leader of the Defense Work Committee said with a smile.

"As users, what do you think of these two plans overall?" The first person to ask this was the Air Force, as they are the users.

"Well, that's good, especially Plan No. 4, which should be the best plan we can come up with now." The Air Force also knows what's good. From the overall architectural point of view, a tailless double-delta wing with immovable canards is the optimal solution under current conditions.

After all, for the delta wing and double delta wing, we have both research and foreign aid, as well as innovation. The risk posed by the canard does not seem to be very high, and the overall performance of this solution is the best result currently available.

In terms of configuration, this is almost an aerodynamically enhanced version of the twin-engine Mirage 2000. If our Air Force was interested in the Mirage 80 in the 2000s, there is no reason why it would not be interested in its enhanced version in the 60s.

Phantom 4000: Thinking about me?

Apart from the differences in size and engine, this No. 4000 plan can be said to be a smaller Mirage .

And the Air Force praised this plan. An important point is that the basis of this plan has a lot to do with the Gauls' Mirage 3.

The Mirage 3, with an Ata-11B of similar level to the R300-F09, can achieve a top speed of Mach 2.2, a range of 2400 kilometers, and a ceiling of 17000 meters, which also proves the excellence of this configuration and is simply tailor-made for heart patients.

Of course, the climb rate of Mirage 3 is a bit ugly, but when we think about our plan of twin-engine, and two developing models with greater thrust than Ata-09B, these concerns were quickly thrown aside by our air force comrades.

The comrades from the Air Force expressed their own preferences. At the same time, Plans 3 and 4 did not have the castles in the air problem of Plan 1, so the subsequent discussion among the comrades became easy.

After a night of research, the comrades were relatively unanimous in their views on Plans 3 and 4 - they were worth pursuing!
The only debate is whether it is biased towards three or four.

"Is number 4 a bit complicated? I think number 3 is better. Whether it is our own research or foreign technology, it can be directly applied."

"I think number 4 is more suitable. Number 3 is too safe and doesn't take any risks. This is not the right attitude to have when developing new equipment."

"Canards will bring greater complexity to the flight control. Is our flight control system at such a high level?"

"I don't think we are afraid. We can just use the wind tunnel to test it more, do more test flights, and make more modifications. Our electronics, computers, and automatic control are pretty good now. In the words of Comrade Zhendong, although Plan 4 is more technically difficult, it truly makes the best use of its strengths and avoids its weaknesses."
