It is for these reasons that Wang Bin has the confidence to buy the pulse detonation engine at this price.


    Later, someone asked Wang Bin, "Mr. Wang, I wonder if you Tiangong technology has a pulse detonation engine with a thrust of about 15 to 18 tons. Of course, I''m talking about static thrust rather than maximum thrust!"


    "President Fang! Don''t worry! I just said that Tiangong technology has various types of pulse detonation engines, so there are more than one pulse detonation engine with about 15 to 18 tons.


    However, Mr. Fang, if your factory uses this engine on No. 20 fighter, I suggest you use this engine after strengthening the body and fuselage of No. 20 fighter.


    Because at present, the fuselage of fighter plane 20 can not bear the speed above Mach 3.2! At the same time, it can not bear the heat generated by friction with the air at such a high speed.


    Therefore, before using this engine, you must strengthen the structure of the body. At the same time, you can''t use the original skin on the skin.


    Of course, my suggestion is that you don''t need to refit the already produced No. 20 fighter at all, but directly modify the existing No. 20 fighter drawing and then carry out production.


    After all, the original No. 20 fighter engine compartment does not match our pulse detonation engine. "


    After listening to Wang Bin''s phone call, president Fang also nodded. After all, it is unrealistic to transform the original No. 20 fighter that has been produced, so his idea is actually the same as Wang Bin.


    Subsequently, the heads of these official airlines all asked about the aircraft engines they needed, and even a manufacturer producing civil airliners also asked Wang Bin.


    Obviously, the head of the East China Sea airlines also wants to build a civil airliner using pulse detonation engine.


    Wang Bin naturally agrees with this. After all, if these aircraft manufacturing enterprises want to build new aircraft, especially those capable of supersonic flight, they must buy various materials from Wang Bin''s Tiangong technology, which is absolutely beneficial to Tiangong technology.


    After everyone''s inquiry, Wang Bin took everyone to the engine exhibition hall of Tiangong technology and saw many prototypes of pulse detonation engine.


    When everyone saw these engines listed in the exhibition hall, everyone was very excited.


    Because of these pulse detonation engines on the booth, the smallest nozzle is only the size of a chopstick, the static thrust is less than 500 kg, and the maximum thrust is less than 1 ton.


    The diameter of the nozzle of the largest engine has reached more than 60 cm, the maximum static thrust has reached 20 tons, and the maximum thrust has reached 40 tons.


    In addition, on the booth, there are all models from one ton and two tons to 189 tons of thrust.


    However, due to the characteristics of pulse detonation engines, the maximum length of these engines is basically much longer than that of turbofan engines.


    If you want to directly install these pulse detonation engines on the existing aircraft, it is still very difficult, because the engine compartment of the existing aircraft can not install these engines at all, so it must be redesigned.


    In fact, since Tiangong technology developed the pulse detonation engine, they have not rested in the pulse detonation engine laboratory of Tiangong technology, but are developing various types of pulse detonation engines, which are the products of the laboratory.


    In addition, even now the pulse detonation engine laboratory is not idle. They are now carrying out a larger R & D plan, that is, to develop pulse detonation engines with greater thrust, such as engines with thrust of 30 tons and 50 tons.


    After reading these engines, we returned to the office again to discuss the order.


    After all, now these people have seen the physical engine, and their hearts are relieved.


    So we immediately placed an order with Wang Bin''s Tiangong technology. However, since they have no available aircraft, they basically only issued five or ten. Obviously, they are ready to transform the old engine drawings or directly develop new engines on the basis of these engines.


    However, there are some exceptions, that is, the manufacturer of Ba ye, who directly issued 500 pulse detonation engines with a thrust of 15 tons to Wang Bin at one time.


    This makes Wang Bin a little curious, but fortunately, the eighth master''s manufacturer did not hide it from Wang Bin.


    Then he told Wang Bin that there were many reasons why they would place such a large order.


    First of all, it is naturally a 15 ton pulse detonation engine, and its maximum diameter is about the same as that of an ordinary turbofan engine.


    Secondly, Baye''s engine compartment is long enough. With a little improvement, you can install this engine.


    Then, the eighth master itself is a high-altitude and high-speed aircraft. Its body strength is absolutely enough. Even if it is not enough, it is much simpler to change than other aircraft before.


    As for the aircraft skin, it is also relatively simple. They can spray Tiangong technology''s special high-temperature resistant powder on the outside of the aircraft skin, and then apply a special high-temperature resistant coating, which can basically withstand the high temperature generated by the speed of about Mach 45.


    Even if they can''t do it at that time, they can learn from a certain type of aircraft in the Arctic and use stainless steel or stronger steel.


    After all, the eighth master is not a stealth machine, but an ordinary non stealth machine. He doesn''t have to consider stealth at all.


    After listening to the eighth master manufacturer, Wang Bin finally knew their plan, so Wang Bin directly signed a supply contract with them.


    After all, because the production of pulse detonation engines is relatively simple, Wang Bin also promised to give them all these engines within two months.


    Of course, with so many pulse detonation engines, Wang Bin has reason to believe that Baye''s manufacturers must have other plans.


    Because the current military certainly doesn''t like the eighth master. Even after the transformation, Wang Bin is sure that the military will never place larger orders. Therefore, Wang Bin believes that the eighth master manufacturer must have bigger plans, but Wang Bin didn''t ask.


    When Wang Bin sent all these people away, Wang Bin was also very happy. After all, each of these people ordered basically little this time, but the combined number is not small, with more than 1000 units, which is enough for their Tiangong technology aeroengine production department to live for a period of time.


    With the departure of these people, Wang Bin was not happy for long. After all, although the orders of these people were huge, there were more important things waiting for Wang Bin, that is, preparing to test fly the phoenix-kt1 aerospace plane.


    And the test flight of this aircraft. At this time, Wang Bin''s heart is also ready to move. He wants to experience it personally in the process of test flight. After all, this aircraft can fly to space! Who doesn''t want to see it.
