The first regret is in the MiG-25 Flying Fox "high-altitude and high-speed volley/battle. , the Soviets did not seem to be mature enough to solve the problem of the "thermal barrier". Otherwise, there would not have been a high-altitude and high-speed interception by the MiG-2 "Flying Foxes/fighters" that melted the skin of the fuselage because they flew too fast.

The other is still from the Soviet Union. And no less frightening Americans. Even the SR-71 "Blackbird" high-speed reconnaissance plane, which the Americans are proud of, was equally frightened. That's nothing else. It is the famous MiG-31 "Foxcatcher" high-performance high-altitude and high-speed interceptor/fighter. The aerodynamic shape of this aircraft and the MiG-25; Not much. In a way. It can be seen as an upgraded version of the MiG-25. Because it itself is an improvement on the basis of the MiG-25.

But don't just think of the MiG-31 as an upgraded version of the MiG-25. Compared to the MiG-25 Flying Fox "high-altitude high-speed volley/fighter. The overall combat performance of the Ge-31 "Foxcatcher" high-performance high-speed interceptor/fighter has been improved several times.

If it is said that the US SR-71 "Blackbird" high-altitude reconnaissance plane had the intention of teasing the MiG-25 "Bat" when it watched its high-altitude and high-speed interceptor/fighter. Then when encountering the G-31 "Foxcatcher" high-altitude high-speed volley/fighter. As long as the SR-71 "Blackbird" high-altitude and high-speed reconnaissance plane reached the shadow of the MiG-31 "Foxcatcher" high-altitude and high-speed interceptor/fighter. The SR-71 "Blackbird" high-altitude and high-speed reconnaissance plane, then, had only one action: increasing the throttle. Run away!

It's interesting. The MiG-31 was aimed at the US SR-71 "Blackbird" high-altitude and high-speed reconnaissance plane and the low-flying "Axe" cruise missile. It is also 25 than the grid. However, the performance of the MiG-31 is much higher than that of the MiG-25. In particular, the MiG-31 fighter is equipped with a phased array antenna, radar and data link. The MiG-31 can also be used as a combat mission in the absence of early warning from the air. And through the airborne data link, the MiG-31 can be used as the command aircraft of the formation, and the United States applies this data link communication technology between aircraft formations. But a little later than the Soviets.

"And. You know me - is this technology really hard there? Xiao Chenxi stared at Zhang Lan's eyes. Those gentle eyes like water. But he seems to be able to see Zhang in the bottom of his heart.

"The ones you have up front are the hardest?" Hearing Xiao Chenxi ask this, Zhang Lan's mouth grew in surprise. "The hardest thing is not the conversion between power and energy?"

"It's not." Xiao Chenxi shook his head. The positive point is. The anti-gravitational device in this system. If there is no anti-gravity device. It is simply impossible for this plane to fly to such a high speed. This device will also be applied to the suit you plan to make. I'll be honest with you. It's just that the manufacturing cost of such an anti-gravity device, I don't think it will be less than $5. Of course. There is another option. That's the nuclear ion engine. That's the power plant used for interspace flight. The cost is higher than the current system! And it's not a little bit high! Are you really going to get this technology out for us. Or rather. Do you think this technology is really necessary for us to roll it out now? ”

"Nope! $5. Hear the numbers. Zhang Lanma shook his head like a rattle: 500 million US dollars is just a one-anti-gravity set. With other equipment, the cost of the whole aircraft will not be less than 1 billion! Such an airplane. Who will you sell it to? It is better to develop its own turbofan engine, so that the aircraft equipped with the existing turbofan engine can fly faster and farther. "At least not for the time being. Even if it's used. Wouldn't have used such a good one. ”

In the foreseeable future. At least within 30 years. Maybe there is no way to put these things into practice Lan sighed in his heart: anti-gravity device? Nuclear ion engines? Oh my God. Is this something that should appear on the ball at this stage? It's just a matter of having fun with yourself. Resolutely not to the market.

He let out a long breath. Even if it's done now. As long as we get a good turboprop engine turboshaft engine. Conventional aero engines such as wheel fan engines and paddle fan engines can already make everyone's jaw drop. As for the wheel-jet engine. If the domestic aviation research institutes are willing to do it, they can do it, anyway, we won't do it. ”

Although in the past, when turbofan engines were not mature enough, turbojet engines had the advantage of high altitude and high speed. But now, after so many years of improvement, the turbofan engine is no slouch even when it comes to the high altitudes and high speeds that turbojet engines do best. But in terms of fuel economy, it is much better than turbojet engines. Didn't you see that even the famous Mi-1 Foxcatcher "high-altitude high-speed volley/fighter jet is also a turbofan type?

"You think so." Xiao Chenxi chuckled. "Listen to what you say, lightweight. But just a few series of engines. In foreign countries, only several engine research companies can do it. In the former Soviet Union, it even took several design bureaus to be able to reconcile. You want to do all these aero engine types in one company. I find that your appetite is not small. ”

"You know that. My mouth has always been big. Zhang Lan smiled. I didn't care much about what Xiao Chenxi said. "That's right. I forgot to ask just now. What is the cost of that ion battery they came to? ”

Zhang Lan was very worried about this problem. Although these things are already very backward for the people of Little Dawn. Theoretically, the cost of this thing should be much lower than the cost of the existing ion battery, but I can't hear Xiao Chenxi give herself a clear answer. Zhang Lan was always a little uneasy.

"At the same capacity. This is only about one-fifth of the existing ion battery manufacturing process on the ball. I heard Zhang Lan ask this question. Xiao Chenxi shook it, obviously a little dissatisfied. "It's a bit disappointing. Our technological superiority is not reflected at all. ”

Heard Xiao Chenxi say this. Seeing Xiao Chenxi's face disappointed. Zhang Lan almost bit her tongue: it is true that the current price of ion batteries is high. A mobile phone battery sells for four or five hundred. The cheap ones are also three hundred. Compared to ten years later, thirty or forty yuan can buy a genuine compatible ion battery. The price of ion batteries is indeed higher now. And a considerable part of the so-called sub-batteries are actually nickel batteries pretended.

Of course. The profit is also quite objective. At present, the cost of ionized electricity for a mobile phone is about 0 yuan. Only one-fifth of the cost. That's just equivalent to the cost of each battery is only about 14 yuan. Zhang Lan estimated and touched. If you announce the news that the production cost of your own ion battery is only about 14 yuan. Angry with the boss of a lot of part of the ion battery company. Belch. It seems that the most angry ones are the Japanese battery companies. ,

"That's pretty good." Zhang Lan smiled bitterly. "1000 ampere-hours is shocking enough. You're not really going to make that 100,000 mAh battery, are you? ”

"Since you're not willing to push that battery into the field. That's it. Just produce a little bit for our own use. Xiao Chenxi said. However, this is only the first test sample in the laboratory. I've asked you to continue to improve the technology. Aim to double the cost on the existing basis. Then, when mass production is carried out, the cost will be reduced a little. If only it could reach this level. It can also be considered qualified to be so-so. ”

Hearing Xiao Chen's words. Zhang Lan was finally completely speechless: reduce the cost to one-tenth or more of the existing cost? That - doesn't it cost only about 5 cents per battery? You know, even if it's an ion battery ten years later. Although Zhang Lan does not know the specific production cost. But it was also roughly estimated. Take the 10 mAh-capacity Scud to produce an ion-compatible battery for BL5C as an example. The retail price in the market is about 35-0. Subtract the profit of the manufacturer, the cost of packaging, the profit of the foreign technology patent manufacturer, the profit of the general agent, the profit of the regional agent, the profit of the third-level agent, the profit of the terminal retailer and the taxes that need to be paid in the above links. Even if it's a lot of competition between everyone. The profit is not that high. No more profiteering. The production cost of an ion battery is about 14.

The only thing to rejoice. type is not those so-called original batteries. Those so-called original batteries. In fact, it is only produced by the country's battery manufacturers. Then it was labeled as a mobile phone manufacturer. Then export it for a circle and then sell it to the country. Then the price horse is able to make two to three times more. That's why there is no difference between original and compatible batteries at all. The reason why the original battery is much more expensive than the compatible battery.

Although there are tariffs, import tariffs and profits of foreign mobile phone manufacturers. But the windfall profits can also be seen. Don't listen to the nonsense of the sales ladies who sell mobile phones. What to say that the original battery is better than the compatible battery. Compatible batteries with high brand awareness. The actual performance is not at all weaker than the original battery. The so-called original battery. In fact, it is compatible with battery manufacturers.
