At the same time, he not only thought that since this Tiangong technology can develop and produce aeroengines, as chief engineer Lin said before, maybe this Tiangong technology has enough skills to solve the biggest problem of their company''s aircraft.


    So he immediately asked Wang Bin, "Mr. Wang, since your company can develop jet aeroengines, I wonder if your company has any aeroengines used on light helicopters?"


    After listening to Du Haili''s words, Wang Bin didn''t answer immediately. After all, although their company has successfully developed a jet aeroengine, it doesn''t mean that their engine can be used on a helicopter immediately.


    After all, the helicopter needs piston or turboshaft engines, but Wang Bin''s Tiangong technology does not have these two engines. Even if they want to use the core machine of the current engine to develop turboshaft engines, it will take at least half a year or even longer to develop them. Of course, this is not over.


    After R & D, a series of tests and commissioning improvements will be carried out, just like these tests of their engine.


    That is, Tiangong technology needs at least one year to develop a turboshaft engine and meet the equipment standards. Of course, this is the fastest speed. If things don''t go well, let alone half a year, even a few years, it may not be possible to develop a qualified turboshaft engine.


    As for the piston aeroengine, it can indeed be designed with the ability of their company. However, it can not be completed in a short time.


    And because of these engine experts in their company, such as Professor poke, they are all experts in jet.


    Therefore, if the piston engine is developed, the time required will never be shorter or even longer than that of the turboshaft engine.


    In addition, even if he purchased the drawings from the system, it will not be completed in a moment and a half.


    However, for the power system of such a light helicopter, it is not impossible to use Wang Bin''s ability of Tiangong technology.


    Don''t forget, they have Tiangong technology, but they have copper based superconducting battery technology and superconducting material technology!


    With these two technologies, if Wang Bin and Tiangong technology are developing a high-power superconducting motor, it is definitely not a problem to drive a light helicopter.


    At the same time, even a light helicopter like this, with the first generation superconducting battery of Tiangong technology, can definitely ensure that the endurance capacity of this aircraft can reach 200 kilometers or even longer, and the endurance speed can definitely be greatly improved.


    At the same time, in terms of superconducting motor, in fact, it is not a big problem for Tiangong technology.


    Because even Wang Bin''s own UAV has a high-power superconducting motor for use when the UAV runs out of fuel or in an emergency.


    Therefore, if there is a real need, Wang Bin''s Tiangong technology can develop a superconducting motor that can be used in their helicopter of Kunlun company in a short time.


    After all, once their helicopter uses the battery of Tiangong technology as energy and the motor as power.


    According to Wang Bin''s estimation, the weight of their helicopter can be reduced by at least half, and the payload can be increased by at least three to five hundred kilograms. At the same time, it will be cheaper in terms of flight cost.


    After all, although the cost of Wang Bin''s battery is very high, if it is really to be sold in the future, the price will be very high. Even the price of the first generation battery will need at least 500000.


    Although the price is high, the service life of this battery is not comparable to that of other batteries. It will not be a problem to use it casually for decades, because it is not a chemical energy battery, so as long as the superconducting coil inside the battery is not aging, the structure is not faulty, and the insulation between the coils is not faulty, there will be no problem with this battery, In other words, even if the helicopter is scrapped, there will basically be no problem with this battery.


    In addition, the electricity in society is basically very cheap. Even if it is industrial electricity, it will not exceed two kilowatts. If electricity is used as energy, then one kilowatt of electricity can at least make the plane fly at least a few kilometers normally. Even with the loss of battery electricity, the cost per kilometer will not exceed one dollar.


    Therefore, what Wang Bin needs to consider now is not whether Tiangong technology has the ability to provide power for their helicopter, but whether Wang Bin is willing to sell batteries and superconducting motors to their Kunlun aircraft.


    However, after thinking about it, Wang Bin said to Du Haili, "Mr. Du, for the piston engine required by your Kunlun company, Tiangong technology has no plans to develop it.


    After all, there is still a gap in efficiency between piston engines and turboshaft engines. At the same time, in terms of turboshaft engines, although our company has research and development plans in this regard, it has no plans to develop turboshaft engines for light aircraft. "


    When Wang Bin said this, Wang Bin could clearly see the disappointment in Du Haili''s eyes, but he still said: "Mr. Wang! If you Tiangong technology really have no way, forget it! It seems that we can only buy light helicopter engines from foreign manufacturers for the time being. We can use our own engines only after we have made a breakthrough in this field."


    At this time, Wang Bin said again, "Mr. Du, please don''t worry. My words haven''t finished yet.


    Although our company has no plans to develop piston engines and light helicopter turbine engines, this does not mean that our company has no power in this regard.


    Mr. Du doesn''t know if your company''s helicopter has considered using electric energy as power. If so, our company can consider selling corresponding equipment to you, that is, super capacity batteries and high-performance high-power motors! "


    After listening to Wang Bin''s words, Du Haili was still disappointed. After all, with the performance of batteries and motors in society, he could not meet the requirements of driving a manned aircraft at all. Even if he insisted on using electric energy to drive, not to mention other performance aspects of the aircraft, only in terms of endurance, it was far from that of a fuel aircraft.


    Because even if the best lithium battery is used as energy, the endurance of its aircraft will not exceed 100 kilometers, or even only dozens of kilometers, and the cost of the battery is not low.
