Since the engine has been inspected at this time, and because of previous experience, the installation speed of this engine is much faster than that of the first installation before, and they quickly installed the second engine.

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

"Old Li! Their Tiangong Technology's engine is really good, and the design is very comprehensive. Not only does it perform very well on our improved No. 6 aircraft, but even in terms of engine installation, various Tiangong Technology has taken all these working steps into consideration.

At the same time, in terms of maintenance in the future, this engine is also considered very well. Even if there are some mechanical problems with this engine in the future, it is not necessary to disassemble the engine before repairing it like other engines. It can be directly repaired on the aircraft without disassembly, which will definitely greatly reduce the work intensity of the maintenance ground staff and other personnel. At this time, a master who was installing the engine said to another master next to him.

"Yes! Old Wang! The engine of Tiangong Technology is indeed very good. I heard that not only our company used this engine, but the test flight of the modified No. 6 aircraft went very smoothly.

Even the No. 8 Transport Aircraft Manufacturing Plant is very satisfied with this engine, and is also planning to place an order for this engine with Tiangong Technology, and the number of orders they are going to place is quite a lot, at least several hundred units as much.

After all, the No. 8 transport aircraft factory is not like the No. 6 fighter that our factory tested. Although our country has successively completed transport aircraft projects such as the No. 9 transport aircraft and the 20th transport aircraft, the No. 8 transport aircraft will not be because of these aircraft. Therefore, the military and other civil aviation groups will also purchase a large number of this transport aircraft, so their group will not lack orders.

Moreover, in addition to the No. 8 transport aircraft using turbofan engines, their company has also started to modify and test flight the No. 8 transport aircraft equipped with electric aero engines.

Even, I heard that their modification process is very fast. Not only have they modified many aircrafts in terms of the No. 8 transport aircraft using turbofan engines, they have even modified the No. 8 transport aircraft using electric aero engines A few planes have been produced, and now the test flight has begun, and the data is the same as our company's, which makes them very satisfied. "Old Li said.

Just as Lao Li and Lao Wang said, in a certain hangar of another aircraft factory in the northwest, six modified No. 8 aircraft were quietly parked in the hangar.

And the six No. 8 planes that have been transformed are not just one model,

Instead, there are two models.

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

And if you look carefully, you will find that the No. 8 transport aircraft that uses propellers in these aircrafts does not seem to be very different from the ordinary No. 8 aircraft, but these No. 8 aircraft are in the same engine compartment as the original The old-model No. 8s are quite different.

First of all, it is natural that the diameter of the propellers of the three-propeller No. 8 aircraft is larger than that of the old No. 8 aircraft, but the diameter and volume of the engine compartment are half smaller than the original ones.

Compared with these engine compartments, there are no intakes and exhaust ports, so it seems that there is still a big difference from the original old model No. 8 aircraft.

Of course, these are just superficial data. If someone can see the data of the three propeller No. 8 planes, they will definitely be even more surprised.

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

And in terms of the weight of the engine, since the efficiency of the motor is much higher than that of the fuel engine, the three aircrafts are not only much smaller in terms of the engine compartment, but also in terms of the weight of the engine itself, it is far heavier than the fuel engine. Much lighter.

In addition, they will also find that the instruments in the cockpits of the three No. 8 planes are also much less, but there are several larger LCD screens.

At the same time, if they know some data about this aircraft, they will definitely be even more surprised, because although the size of these three aircraft is not large, their battery life is not bad. Compared with some long-range transport aircraft, if the backup battery compartment of the aircraft is filled with spare batteries, its cruising range may exceed that of long-range transport aircraft and reach the endurance of intercontinental transport aircraft.

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

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

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

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

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

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

That's why the carrying capacity of this aircraft is so excellent, it can even be comparable to that of a heavy transport aircraft.

Of course, if you want to actually transport nearly 50 tons of cargo, you will naturally have to strengthen the internal cargo compartment of this aircraft to a certain extent.

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

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