After half an hour''s flight, Wang Bin''s helicopter was very close to the accident site. On the plane, Wang Bin could clearly see the wreckage of a huge plane on the ground, and there were a large number of wreckage around.


    In addition, there are also a large number of personnel near the wreckage of the aircraft. These personnel include both military researchers wearing uniform and the clothing of the aircraft manufacturer, and these personnel are the personnel of the very manufacturer of the aircraft.


    When Wang Bin''s plane stopped, Wang Bin and the technicians of Tiangong technology immediately got off the helicopter, came to Qiu Shi, asked Qiu Shi, "how''s Qiu Shi 1 aka? Have the on-site inspection results come out?"


    At this time, Wang Bin and other people from Tiangong technology are most concerned about the cause of the plane crash, whether it was caused by the engine.


    If it is really caused by the engine, it shows that the engine designed by Tiangong technology really has fatal defects. They must investigate the engine and find out the defects. If they can''t find the reason, it means that the engine can''t be mass produced and equipped.


    Qiu Shi obviously knows this. The crash of the plane was caused by the engine shutdown, which is absolutely huge pressure for the engine manufacturer.


    After all, the energy and capital required to design and develop an engine are very huge. Once the investigation results are really the cause of the engine, so long means that all previous R & D and design of their engine may be wasted.


    After listening to Wang Bin''s phone call, Qiu Shi shook his head to Wang Bin and said, "don''t worry, Mr. Wang! After our preliminary inspection, the engine shutdown of this aircraft is not caused by your engine.


    According to the flight data recorder of the aircraft, everything of the engine is very normal during the flight, but suddenly the fuel supply of the aircraft is directly cut off, which leads to the shutdown of the engine. After all, no matter how excellent the engine is, once the fuel cannot be supplied, the engine will not work.


    At the same time, according to the wreckage at the scene, even if the plane has crashed at this time, your Tiangong technology engine has not suffered much damage. Only the protective shell of the engine has suffered some damage, so the on-site inspectors can easily check the engine.


    But now, although we have basically determined that the failure of the aircraft''s fuel supply system led to the air shutdown of the engine.


    However, we are still unable to determine the specific situation and need further investigation. "


    After hearing Qiu Shi''s words, Wang Bin was obviously relieved, but at this time, he had another question in his mind, that is, the engine developed by Tiangong technology can be driven directly by electricity in addition to using the fuel system, because in their Tiangong technology engine, But there is a small high-power high-speed superconducting motor.


    In general, when the aircraft uses fuel for flight, the motor is used as a generator. However, once the fuel of the aircraft has a problem, the motor can be converted immediately and become a power output source to provide power for the aircraft and avoid the crash of the aircraft due to fuel problems.


    Therefore, even if the fuel system fails, with power, the aircraft can fly a distance and land safely.


    Although using electric power to drive flight, its maximum speed can only reach 500 kilometers per hour, and its range is only one or two hundred kilometers.


    So Wang Bin asked, "Qiu Shi, didn''t your pilot try to fly with electricity when there was a problem with the plane''s fuel system? There was also a problem with the difficulty power system?"


    "What? Electric drive flight, your engine still has this function?" after listening to Wang Bin''s words, Qiu Shi turned and said to Wang Bin in shock.


    "Yes! Qiu Shi, don''t you know this function? I remember our engine, but the manual clearly states that the generator on our engine can also be directly used as the standby power of the engine?" Wang Bin said.


    Seeing Qiu Shi''s expression, Wang Bin knew that Qiu Shi obviously didn''t know that Tiangong technology engine had this function, and the aircraft manufacturer didn''t tell Qiu Shi that this aircraft had this function.


    It is even possible that aircraft manufacturers have not paid attention to this problem at all.


    So he immediately asked someone to bring the operating instructions of the aircraft.


    Soon, someone brought the operating instructions of the aircraft.


    Then Wang Bin and Qiu Shi read the operating instructions of the aircraft. However, they regretted that they did not find this function in the operating instructions. That is to say, although the engine of Tiangong technology had this function, the design of the aircraft was improved and did not make this function work, Only the motor in the engine is used as a generator.


    Both Qiu Shi and Wang Bin are very clear about this. At the same time, they also have regrets. After all, it is not complicated to make this function work. As long as a superconducting battery and several lines are installed on the aircraft, this function can play a role, so this accident can be avoided, But the manufacturer didn''t do it, which directly led to the crash of the plane, which is definitely the lack of the designer.


    Wang Bin could only sigh and was speechless for a moment.


    Qiu Shi was very excited at this time. After all, the accident could have been avoided, but due to the designer, it directly led to the crash of the aircraft, and the cause of the accident may also be caused by the designer who improved the design. After all, there are problems in the fuel system, in addition to possible problems in components, The rest can only be caused by design defects.


    However, after seeing Qiu Shi, there is little chance that the aircraft will have problems in terms of parts, because except for a small number of parts of the fuel system of the aircraft, other parts are the parts on the old No. 6 aircraft, which has been used for so long and has not had this problem, but the new aircraft has appeared, Then it''s definitely a defect in improving the design.


    Of course, Wang Bin thought of these at this time, so he continued to ask Qiu Shi, "Qiu Shi, is the improved design of this aircraft designed by this aircraft manufacturer or by other designers?"


    "The improved design of this aircraft is not all designed by the aircraft manufacturer. According to the Convention, except for the aircraft body, others are designed by many professional official design institutes in China!" Qiu said helplessly.
