Thinking of this, Wang Bin was a little depressed, but then he thought of the current situation of Tiangong technology. Now Tiangong technology has started the research and development of large civil aircraft engines. At the same time, in terms of large air vehicles, Tiangong technology has already started the research and development, that is, the research and development of Phoenix bombers.


    Therefore, as long as Tiangong technology can successfully develop Phoenix class bombers and fly successfully, it is not difficult for Tiangong technology to develop large civil aircraft.


    Thinking of these, Wang Bin has secretly decided that when the military order meeting returns, Tiangong technology must carry out the research and development of civil aviation large passenger aircraft, and what Tiangong technology wants to develop must not be the same as the type 21 passenger aircraft currently being developed in China, but a subsonic passenger aircraft, which must be a supersonic passenger aircraft, And in terms of passenger capacity, it must also reach the level of large aircraft.


    Of course, this is just what Wang Bin thinks now. Specifically, we should see the design of their Tiangong technology technicians. If the technicians say that they can''t design and manufacture large supersonic civil aircraft with their current ability, Wang Bin has no way.


    Soon, Wang Bin and others walked out of the airport and walked to the hotel that had been booked for a long time.


    "Mr. Wang, seriously, I really envy your Tiangong technology. The performance of this tg001 engine developed by your Tiangong technology is really excellent. Even if it is the most advanced aero engine in China, there is still a certain gap in its comprehensive performance compared with your engine. If there is no accident, this paragraph After getting on the bus to the hotel, chief engineer Lin said to Wang Bin.


    "Chief engineer Lin, your 969 group is not bad. After all, compared with other military units, your 969 group is the best in land combat units! You can get a lot of orders every year!" Wang Bin said with a smile.


    "Mr. Wang! Although our 969 group is the largest production and design group of land combat units in China, and there are not a few equipment purchased from us every year, in recent years, due to the change of international war mode and the possibility of large group combat mode, the military''s investment in the army has been gradually reduced.


    Therefore, even if our 969 group is the largest land combat unit production group in China, it has naturally received a great impact, "chief engineer Lin said.


    Wang Bin nodded. Of course, Wang Bin knows this. After all, with the international war situation and the change of national strategy, the state''s investment in the Navy and air force is increasing day by day. Although the investment in the army is also increasing, it is not as big as the Navy and air force. Naturally, their 969 group will also be affected.


    "By the way, Mr. Wang! I heard that your Tiangong technology has developed a high-performance battery with an output power of 500 kW and a maximum output voltage of 500 v. I don''t know if this is true." just when Wang Bin wanted to say something, Mr. Lin said to Wang Bin again.


    "Yes, chief engineer Lin, our Tiangong technology has indeed developed and issued two kinds of high-performance batteries. These two kinds of batteries are copper based superconducting batteries, which are the first generation and second generation superconducting batteries developed by our Tiangong Technology Institute. The defects of the first generation battery are very obvious. Its maximum output power is only about 100 kilowatts and its maximum output voltage is only 200 kilowatts V, which is similar to the voltage of ordinary civil electricity. In terms of energy storage, this battery can store about 100 kilowatts of power, and this battery can''t be connected in parallel or in series.


    The second-generation superconducting battery is a battery developed by Tiangong technology based on the first-generation superconducting battery technology. Its maximum storage capacity is 500 kW, the maximum output power is 500 kW / h, and the maximum output power can reach about 500 v. it can be output in parallel, but it can''t supply power in series. "Wang Bin nodded.


    "What? It''s true. I don''t know the price. If we can, our 969 group wants to buy a batch.


    To tell you the truth, recently, our 969 group has received another project, that is, the research and development of the chassis of the new heavy-duty combat vehicle, and the superior has very high requirements for the chassis of this combat vehicle, requiring that the maximum horsepower must be more than 1800 and the maximum driving speed must be able to reach 100 km / h, which puts forward non-standard requirements for the engine system of this combat vehicle Often demanding.


    There are very few such chariot engines in China, or even none, unless we use turboshaft engines as the power of this engine like owl chariots. However, such turboshaft engines also have many difficulties for us.


    Originally, we wanted to ask whether we could get 1800 horsepower chariot engine abroad, but now it seems that we don''t need it. After all, with your battery, we can use electricity to drive our chariot site.


    After all, compared with other driving methods, we are good at electric driving. We don''t even need to re develop the corresponding motor, so we have available motors.


    Although the maximum output power of 500 kilowatts of 500 volts is not enough for large equipment, such as ships and warships, it is enough for chariots.


    And the advantages of using the motor for driving are much better than using other methods of driving, such as diesel engine and turboshaft engine. First, the size of the motor is obviously much smaller than that of diesel engine and turboshaft engine, or even only one tenth of the size of other engines.


    And with electric drive, the chariot doesn''t have to carry a huge and dangerous mailbox, so we can save a lot of space to install other equipment and store more ammunition, and even upgrade armor at the same time.


    In addition, if we use electric drive, we don''t need to use one-way drive at all. We can use multi-point drive. For example, the chariot can drive each wheel, and even the lower load wheel can drive. In this case, even on the battlefield, in case of track problems, Chariots can also retreat or continue to attack at the first time When chief engineer Lin heard that Wang Bin said it was true and listened to Wang Bin''s introduction, he was excited at once.


    After all, compared with the fuel driving mode, the advantages of using the electric driving mode are too many. The most intuitive thing is that it can save the internal space of the combat vehicle to the greatest extent.


    At the same time, there is no need to spend time and effort to develop an 1800 horsepower engine. After all, even if you buy technology from abroad, you can''t achieve it in a moment and a half.


    In terms of motors, not to mention 1800 horsepower motors, even if they are 2000 kW or even 3000 kW or more, there are some in China.
