Chapter 1556: Pain and happiness

As mentioned in the previous article, Huaxia is actually no stranger to phased array radars. As early as the 1970s, it successfully developed strategic early warning radars using this system. It is known as the
7010 Project
in history. Tan Zhenhua’s own father, Tan Ming, was also One of the competitors of the chief engineer of the project, later served as the chief engineer of the radar display subsystem.
But even if they are all phased array radars, there are still many differences. According to the working principle, there are active and passive. According to the devices used, there are solid and vacuum points. Even if they are all solid semiconductors, there are materials. For example, the "7010 Project" of the year was a typical passive phased array radar. It used 4 high-power multi-cavity klystrons (vacuum devices) with a total peak power of 10 MW and an average power of 200 kW. For the transmitter, a 20m40m antenna array of a feed unit composed of 8976 high-power thyristors (semiconductor materials) is arranged at the same time, while the signal processing unit uses solid-state devices (semiconductor materials) and Combination of vacuum devices (electronic tubes).
The "7010 Project" achieved the design goals, which enabled China to break through the phased array radar system and cultivated a large number of outstanding radar talents. However, in the actual use of this radar, a series of problems were exposed. For example, the failure rate is high; for another example, the volume and weight are extremely large, and the energy consumption is extremely high. You must know that in order to install this strategic early warning radar, the entire mountain of Xuanhua Huangyang Mountain was hollowed out. The Ministry of Radar has built a power plant.
Although Zhang Jun is the minister of the Ministry of Aeronautics and Astronautics and has a very detailed source of domestic development intelligence on various related industries, he is not a professional in the radar industry after all, so he can only say that he understands the situation of airborne radar but is not in-depth enough. In his impression, the radar on the domestic "Eagle Eye" invested by Tan Zhenhua is not in the state of development, and the PD radar currently equipped on the "Flying Leopard" fighter is the most advanced currently available in China. Airborne radar is now available. Can the big guy with the phased array system like the "7010 Project" be moved to the plane?
"Minister Zhang, the current progress of this matter will be kept secret for the time being, but I can guarantee that in the future, our country’s own strategic early warning aircraft will definitely adopt the phased array system, and it will be the phased array system of active electronic scanning. With the control system, we shouldn’t just stay in the footsteps of the Americans. To catch up with and surpass it is our ultimate goal!
Tan Zhenhua replied categorically.
...
Tan Zhenhua’s first negotiation strategy to win over JAA has had the expected effect. This is like the "Three Kingdoms Kill". The two relatively weak parties have a natural motivation to cooperate. The European civil aircraft manufacturing group led by Airbus has long been suppressed by Boeing. After living for a while, everyone can see that China’s growing consumer market is the best hope for Europeans to come back in the market!
Is to continue the previous policy, and Huaxia people to delay to the end, close the market to each other, sit and watch the continuous technological progress of Huaxia people, and explore and consolidate the domestic and even surrounding markets that are not under the jurisdiction of Europe and the United States, or let it go. Do you know how to fight in the market competition?
The Europeans finally made a painful and happy decision.
They put forward the latest exchange conditions, these conditions mainly include:
1. Require European companies to fully participate in the bidding of the sub-system supply of the C929 airliner under fair and open conditions;
2. Liberalize the China Airlines aircraft procurement market, and allow Airbus's short- and medium-range aircraft to participate in the procurement bidding of China's civil aviation operating companies without the restrictions of quotas and other non-market administrative management methods under the condition of complying with the CACC safety license;
3. Fit the C919 passenger aircraft to the Safran Group CFM56 series engine, a joint venture between Gaul and the United States, and become one of its recommended engine models. The specific purchase intention is determined by the end user;
4. Include Rolls-Royce's "Ruida 700" series engine in the C929 standard engine model list for customers to choose;
China Civil Aviation Administration agreed in principle to these requirements put forward by JAA. So far, the negotiation between China and the European Community on mutual recognition of each other’s airworthiness certificate has finally broken through the principled barriers and entered the stage of substantive negotiation of specific implementation terms. This indicates that after years of hard work, China’s domestically produced passenger aircraft has finally seen the dawn of success in its efforts to enter the mainstream European market.
There is no impermeable wall in the world. After learning of the actions of the Europeans, the Americans immediately launched actions. Just like their usual practice, the Americans immediately launched actions. On the one hand, they are lobbying or lobbying the European Community from all levels. Putting pressure on, trying to set up various obstacles for the negotiation between JAA and CACC, delaying and obstructing the negotiation process; on the other hand, the FAA itself stepped up the negotiation with CACC, trying to win the mutual recognition with CACC before the Europeans Airworthiness certificate, if possible, it is best to temporarily exclude Europeans, the longer the better. Of course, according to the U.S. people's usual urine, any reciprocal negotiation will be treated as a charity to other countries, so the conditions they put forward are much harsher than Europeans.
However, negotiating things is like playing cards. In addition to confidence and will, what you need to compete is the size of the cards in your hand. At this time, China Xia holds the world’s largest civil aircraft market in the future. , And C919, ARJ21-70, and ARP21-50 (both the official names of the "Seven Major Changes" models cooperating with BAE) these three "2s". This is a good hand. As long as you don’t play indiscriminately, it’s hard to lose. !
Continue to bargain with Europeans and continue to entangle with Americans. This is not something the second young master likes to do. So he is handing over to Minister Zhang Jun and Zhang, saying that he can promise Americans the most Like the Europeans, they agreed to participate in the development and bidding of C929 by the various sub-system suppliers in the United States. They can also adapt the C919 and C929 to the CF series of the United States and the PW series of Pratt & Whitney.
Well, these two idioms are slightly inaccurate. The real situation is that Tan Zhenhua does have important things and has to leave to deal with it.
Because, on April 23, the annual Chinese Navy Festival is approaching, and he was officially invited by the Navy to go to the Sanya Port of Qiongzhou to observe the ceremony.
Moreover, this navy festival is destined to leave a strong mark in the history of the China Navy.
Tan Zhenhua is the initiator, behind-the-scenes manipulator, and specific executor of this pen.
Well, since this is a typical gang crime, so, "one" has to be added.
