Because the engine has been inspected at this time, and due to one experience, the installation speed of this engine is much faster than that of the first installation before. They soon installed the second engine.


    At the same time, when installing the second engine, the hoisting, mobile installation and other procedures were also very smooth, and there were no problems. After all, these workers and masters who hoisted the engine were all teachers.


    "Lao Li! The engine of Tiangong technology is really good. They have considered the design very comprehensively. They have not only played a very good performance on our improved No. 6 aircraft, but also considered various procedures and work steps in the installation of the engine.


    At the same time, in terms of future maintenance, this engine is also considered in place. Even if there are some mechanical problems with this engine in the future, it does not need to be disassembled for maintenance like other engines. Instead, it can be directly repaired on the aircraft without disassembly, which will definitely greatly reduce the cost of maintenance ground crew and other personnel Work intensity. "Then a teacher who was installing the engine said to another teacher next to him.


    "Yes! Lao Wang! The engine of Tiangong technology is really excellent. I heard that not only did our company use this engine, the test flight of the modified No. 6 aircraft went very smoothly.


    Even the No. 8 transport aircraft manufacturer is very satisfied with this engine and is ready to place an order for this engine with Tiangong technology. Moreover, they are ready to place a large number of orders, at least hundreds.


    After all, the No. 8 transport aircraft factory is not like the No. 6 fighter aircraft tested in our factory. Although our country has successively completed the No. 9 transport aircraft, No. 20 transport aircraft and other transport aircraft projects, the No. 8 transport aircraft will not be eliminated because of the emergence of these aircraft. The military and other civil aviation groups will also purchase a large number of this transport aircraft Their group will not lack orders.


    Moreover, in addition to the No. 8 transport aircraft with turbofan engine, it is said that their company has also carried out the transformation and flight test of the No. 8 transport aircraft with electric aviation engine.


    Even, I heard that their transformation process is also very fast. Not only in the No. 8 transport aircraft with turbofan engine, they have transformed many aircraft, and even the No. 8 transport aircraft with electric aviation engine, they have transformed several, and now they have started test flights. The data are the same as that of our company, which makes them very satisfied. " Lao Li said.


    As Lao Li and Lao Wang said, at this time, in a hangar of another aircraft manufacturing plant in the northwest, six modified No. 8 aircraft were quietly parked in the hangar.


    The six modified No. 8 aircraft have not only one model, but two models.


    They are No. 8 aircraft with tg-s002 engine and test propeller engine respectively.


    And if you look carefully, you will find that the No. 8 transport aircraft with propeller in these aircraft does not seem to be very different from the ordinary No. 8 aircraft, but these No. 8 aircraft are very different from the original No. 8 aircraft in the engine compartment.


    First of all, naturally, the propeller diameter of the three propeller No. 8 aircraft is larger than that of the previous old model No. 8 aircraft, but the diameter and volume of the engine compartment are half smaller than the original.


    Compared with these engine cabins, there is no air inlet and exhaust port, so it looks very different from the old model No. 8 aircraft.


    Of course, these are only surface data. If someone can see the data of these three propeller 8 aircraft, they will be more surprised.


    First of all, they will be surprised to find that the three No. 8 aircraft do not use fuel engines as power, but use four special motors to drive the propeller to rotate.


    And in terms of engine weight, because the efficiency of the motor is much higher than that of the fuel engine, the three aircraft are not only much smaller in the engine compartment, but also much lighter than the fuel engine in terms of the weight of the engine itself.


    In addition, they will also find that there are many fewer instruments in the cockpit of the three No. 8 aircraft, but there are several large LCD screens.


    At the same time, if they know some data of this aircraft, they will be even more surprised, because although the volume of these three aircraft is not large, their endurance capacity is not poor. Under the condition of full cargo, they can be compared with some long-distance transport aircraft. If they are filled with backup batteries in the backup battery compartment of the aircraft, Its endurance mileage may exceed that of long-range transport aircraft and reach the endurance capacity of intercontinental transport aircraft.


    The second is the transport capacity of the aircraft. After all, as a transport aircraft, transport capacity is the key.


    As a No. 8 aircraft, the maximum carrying capacity of the old model before the transformation is only about 25 tons to 30 tons.


    But now, according to the previous flight test data, the carrying capacity of these three transport planes has actually reached about 50 tons. You know, this is just a medium-sized transport plane!


    The carrying capacity of a medium-sized transport aircraft in the world is basically about 30 tons. But now! The transport capacity of this transport aircraft has immediately reached the carrying capacity of heavy transport aircraft.


    In fact, this is because the engine used in this transport aircraft is no longer a fuel engine, but an electric engine, and the efficiency of the electric drive is far from that of the fuel engine.


    The most important thing is that the battery installed on the aircraft has a very high energy density, so the aircraft naturally does not need to carry dozens of tons of fuel weight, and the excess weight can be basically used to improve the carrying capacity of the aircraft.


    Therefore, the carrying capacity of this aircraft is so excellent that it can even be equivalent to that of a heavy transport aircraft.


    Of course, if you want to really carry out the transportation of nearly 50 tons of goods, you naturally need to strengthen the internal cargo warehouse of the aircraft to a certain extent.


    Otherwise, the weight of the cargo alone would be enough to crush the internal structure of the aircraft.


    However, the design and transformation personnel of the aircraft have long thought of these, and have reinforced the internal structure and even the body of the aircraft. Therefore, the transportation capacity of these three special No. 8 aircraft can definitely reach about 50 tons.
