After the first unmanned test flight was successful, Qiu Tuan and others went back that day, while Wang Bin immediately sorted out the data after the test flight, and began a series of inspections on the aircraft. Ten days later, the aircraft stopped at the runway again.


    However, the difference between this test flight and the previous test flight is that this test flight is not an unmanned test flight, but a real manned test flight. Like the previous test flight, Qiu Tuan and others also came to Wang Bin''s Tiangong technology early.


    And this time they also came prepared. This time, there were not only Qiu Tuan and other people who had been here last time, but also more than a dozen soldiers who came with Qiu Tuan. Most of these people had similar positions as Qiu Tuan, but the positions of two people were higher than Qiu Tuan.


    In addition, Qiu Tuan didn''t come empty handed when they came here. They also brought an armored vehicle with an additional armor and a weight of nearly 30 tons. Obviously, they want to really test the real load capacity of the aircraft.


    In this regard, Wang Bin naturally agreed very much, and immediately arranged personnel to quickly bring the armored vehicle to the transformed No. 9 transport plane. Even for the test data, he added nearly six tons of goods on the plane.


    That is to say, at this time, the cargo carried by this modified No. 9 aircraft has reached about 36 tons.


    In addition, at this time, the aircraft has been completely filled with fuel. It is obvious that this manned test flight is still a test flight in full state. Therefore, it is definitely a challenge for this modified transport aircraft No. 9.


    "Mr. Wang! I don''t know if you have confidence in this test flight. If you don''t, don''t install goods first and carry out empty flight test first!" as the scheduled test flight is getting closer and closer, an old chief who came with Qiu regiment said to Wang Bin with some worry.


    "Don''t worry! Wan Lao! We are very confident in the No. 9 transport aircraft after our transformation. After all, before the transformation, if the aircraft was not filled with fuel, its ultimate carrying capacity reached about 30 tons. Now we have not only strengthened the fuselage, but also the cargo warehouse The strength of the cargo warehouse is higher, so there is absolutely no problem, and if the aircraft is not filled with fuel, the ultimate carrying capacity of the aircraft will be higher! "Wang Bin said confidently.


    After listening to Wang Bin''s words, wanlao was obviously relieved, but there was still some worry on his face.


    Seeing Wan Lao''s situation, Wang Bin knew in his heart that he was not completely relieved. The most important thing was that this test flight was a manned test flight. In case of an accident, the test flight personnel on the plane would definitely be in great danger, so he said: "In addition to these, we have also installed a variety of pilot safety protection equipment on the aircraft, including escape equipment. Once the aircraft has a situation, the pilot on the aircraft can definitely escape the aircraft within one second to ensure safety."


    "That''s good! That''s good! After all, there are no planes and they can be rebuilt, but the country has spent a huge price to train a pilot, especially an excellent pilot like Xiao Lu. Moreover, Xiao Lu seems not to be married, so I don''t want to see any accidents," Wan Lao said.


    Wang Bin is naturally very clear about the difficulty of training excellent pilots. That''s why Wang Bin spent a lot of energy only in safety when they transformed the aircraft. Therefore, although he can''t guarantee that the pilot can escape 100% in case of an accident, if there is no mistake in operation, the probability of escape is extremely high Yes, it will be more than 98%.


    As the dialogue between Wang Bin and WAN Lao fell, the final preparations for the No. 9 aircraft on the runway had been completed, and Lu Bo and another test pilot also boarded the aircraft that was about to be tested and began to check the equipment and instruments of the aircraft to see if there were any missing problems.


    At the same time, on the side of the flight control center, the flight control personnel have also turned on the aircraft''s real-time data transmission system. However, due to the manned driving mode, the ground cannot operate the No. 9 aircraft. The ground flight control center can control the aircraft only after the pilots on the aircraft turn on the ground control mode.


    "Report! The aircraft instrument is normal, the engine is normal, and the airframe condition is normal......"


    "The plane is checked, everything is normal, request to take off!" with Lupo''s inspection of the plane completed, he immediately applied to the tower for taking off.


    After receiving the request, the tower immediately agreed to his takeoff request.


    So the No. 9 plane began to slide forward in everyone''s attention, and when it ran for about one kilometer, the plane began to leave the ground slowly. It is obvious that even under the condition of full load, the taxiing distance of the plane is definitely much shorter than that before the transformation.


    Seeing this, Wan Lao and others nodded with a smile. Obviously, they were very satisfied with the take-off distance of the plane.


    Like the first unmanned test flight, the plane immediately flew over the sea after taking off and began test flights in various subjects.


    With the flight test projects going on one by one, Wan Lao and others'' faces are finally getting better and better. Finally, their faces are full of smiles. Especially when the aircraft is fully loaded, the maximum flight altitude reaches 1300m and the maximum speed reaches 800km, Wan Lao and others'' faces are even more happy.


    "Mr. Wang! That''s good! The performance of the No. 9 aircraft you transformed is really excellent, so I''m looking forward to it very much," wanlao said.


    "Mr. Wan, you flatter me. After all, there will be more flight test subjects, including flight test under various extreme environments, such as flight under extremely cold conditions, engine operation, flight under extremely high temperature, take-off and landing in high altitude areas, etc.


    Only when all these flight test subjects are completed and meet the expected data requirements can it be regarded as success, otherwise, it will not be regarded as success! "Wang Bin said modestly.


    "No! Mr. Wang! I also agree with what Wan Lao said. Although this is the transformed No. 9 aircraft, this is only the first manned flight, it is against your Tiangong technology''s self-confidence, which can not be compared with other enterprises. If this aircraft is transformed by other enterprises, I absolutely have no courage to fly at the highest speed and altitude All right, not to mention flying under full load. From this, we can definitely see your Tiangong technology''s confidence in the engine you developed and in the modified aircraft. "
