However, when Wang Bin and his colleagues returned to their paste technology, Du Haili also returned to their company and immediately contacted the relevant company that provided them with the engine. However, the other party''s answer was even more angry and disappointed.


    "Hello, Mr. Du! It''s your company''s own business about your problem. It must be that the helicopter designed by your company is unreasonable, not the engine sold by our company to you, because the engine we sold to you is the engine selected by your company before.


    At that time, this engine was also a qualified product after our company''s strict inspection, not a defective product. "After Du Haili got through to the Ross aeroengine company, the person in charge of the other party said to Du Haili.


    "Mr. Ross! How is this possible? The helicopter designed by our company has been rigorously tested by our R & D personnel, and has also passed the official test of our country. There is no fatal problem before it is manufactured, so it is not our design problem.


    The most important problem is that according to the test of our company''s technicians, the power and performance of your engine did not meet the standards in the data your company gave us before, and even the horsepower was nearly one-third less in terms of power. Mr. Ross, how do you explain this! "Du Haili was even more angry after listening to the person in charge of the other company.


    The other party didn''t seem to hear Du Haili''s angry words, but directly said to Du Haili without delay: "Mr. Du, there is nothing to explain about our company, because the data previously sent to you are the prototype developed by our company, and the overseas version of our company and the products that can be sold to your company are sold to you.


    As for the original model, our company has no way to sell it to you, because the original engine is not within the scope of the Huaxia list that can be sold to you, that is, this engine is prohibited from being sold to you, whether it is an official or private enterprise. "


    "Mr. Ross, if you do business like this, are you not afraid of losing customers? What''s more, even if you no longer export Huaxia products, won''t your company think of a way? You know, once our company determines that this helicopter uses your engine, the quantity required in the future will definitely not be small." At this time, Du Haili still held a lucky heart and hoped that the other party would sell the engine he liked before to their Kunlun company.


    However, the other party''s answer also made him completely lose heart to foreign engines.


    I saw the other party say: "Mr. Du, there is no way for our company, because this is not set by our company and the prohibition is not formulated by our company. Therefore, if President Du really wants to purchase this engine of our company, only the one we have sent you. As for the matter that the horsepower can not meet the requirements of President Du, you can tell president Du Improve your company''s helicopter to reduce its weight, or buy an engine with better performance from our company, that is, another engine you have seen in our company before! "


    "Mr. Ross, are you kidding? What''s the difference between modifying the helicopter drawings and redesigning a helicopter? It''s too expensive.


    Our company certainly won''t do that. As for another engine of your company, let alone another engine of your company, although it has greater horsepower, its weight and size are also larger, and its price is three times that of the previous one. The most important thing is its performance, which can''t meet the requirements of our company, "Du Haili said.


    Later, Du Haili also talked with the other party, but the other party just didn''t let go and refused to sell the original engine of their company to them. He even said frankly that if there were no engine of their company, there would be no other engine company in the world that would sell engines with comparable performance to them.


    At the same time, he also said that even if Du Haili''s company is given another ten years, it is impossible for his company to produce an engine with comparable performance to that of his company, and it is impossible to produce a helicopter with satisfactory performance.


    The other party''s words almost made Du Haili spit blood angrily. After all, the other party''s words are really irritating. Of course, if Du Haili''s company is an official company, he can take it back, and then work hard to organize personnel and invest a lot of money to develop the corresponding engine in a short time.


    Unfortunately, their company is not an official enterprise, but a private enterprise. Their scientific research strength and financial strength are neither allowed nor possible to support them to develop and issue qualified engines in a short time. Otherwise, they don''t want to buy engines from Ross company.


    After a while, Du Haili calmed down. At this time, he no longer expected the engine of foreign companies.


    Because what rose said before has been made very clear, it is definitely impossible for their rose company to sell the original engine to them.


    As for other companies, he can also be sure that Ross has said hello to them. It is impossible to sell the engine to Kunlun company. Even if it is sold, it will definitely be a castrated version like Ross company, and its performance will never meet the requirements of their company.


    So now there are only two ways for their company. The first is to buy the more expensive engine of Rose''s company, and then modify the helicopter of their own company to meet the requirements of installing that engine. The second is to ask the official for help, It is hoped that the government can develop an engine suitable for their company''s helicopter.


    However, he knew that even if he turned to the government, it was impossible for the government to develop an engine suitable for their company''s helicopter in a short time. Even the government could not spend a huge price to develop an engine specifically for their company.


    Thinking of this, he sighed. For a moment, the blood couldn''t think of any good way.


    At this time, he suddenly thought of the words of chief engineer Lin and chief engineer Wang of Tiangong technology in the test flight field.


    Chief engineer Lin and Wang Bin, one is the chief engineer of the 969 group, and the other is the boss of a powerful company. Since they all say so, they will not be targeted. They must have their own confidence. Not to mention anything else, in this test flight field, the UAV that Tiangong Technology carries out test flight can not be developed by ordinary enterprises.


    So he immediately turned on the computer and looked for the news about Tiangong technology on the Internet. He found that Tiangong technology was really unusual. It had not only made great achievements in special steel, but also made strong achievements in special glass. Even its subsidiaries had manufactured the largest telescope lens in the world. Most importantly, their company also has deep cooperation with official enterprises such as 969.
