After listening to Wang Bin's words, Professor Dai said without thinking: "According to the county meteorological department, except for the bad weather tomorrow, the supply situation in the next few days is good, which is very suitable for the test flight work, so I It is better to let the staff rest for a day tomorrow, and then carry out the test flight work the day after tomorrow, after all, these personnel who have carried out the modification work during this period of time are not lightly tired!"

"That's fine, then we will conduct a test flight the day after tomorrow, and at the same time inform Second Lieutenant Lupolu. After all, as the military representative of our Tiangong Technology, we must participate in the test flight!" Wang Bin said.

"Okay, Mr. Wang! Wait a minute, I will notify Second Lieutenant Lu to participate in the flight test!" Just after Wang Bin finished speaking, Wang Xu nodded and said.

Soon, it was time for the test flight of the No. 9 plane. Early in the morning, Wang Bin, Prof. Dai and others came to the hangar to check the condition of the plane. Not long after they arrived, they also came to the hangar.

"Mr. Wang! How's the situation? I think the weather in the morning is a bit gloomy. Do you want to fly today?" Second Lieutenant Lu asked Wang Bin after he arrived.

"Second Lieutenant Lu, the condition of the plane is very good, all within the allowable range of the data. As for the weather, according to the data of the county meteorological department, although the current weather is a bit gloomy, it will clear up after a while, so the test flight is absolutely No problem!" Wang Bin said.

Sure enough, when it was a little past nine o'clock in the morning, the gloomy clouds and mists in the sky had dispersed, and the sun appeared in the sky.

In this regard, Wang Bin and others immediately opened the hangar, and then used a professional aircraft tractor to tow the No. 9 transport aircraft to the take-off point of the airstrip, and began to add fuel to the aircraft.

Since this test flight is the first test flight of this aircraft, the test flight time of the aircraft will not be too long, only ten or twenty minutes. The fuel filling is complete, and the aircraft will also usher in the first test flight after the transformation.

However, before Wang Bin and the others started to take off, Wang Bin received a call from the guard and told Wang Bin that Qiu Tuan and others were here, and their purpose of coming to Tiangong Technology was naturally It is to visit the modified No. 9 non-motorized test flight.

Regarding this, Wang Bin naturally asked the guard to bring Qiu Tuan and others to the runway.

Only five or six minutes later, Wang Bin saw Qiu Tuan and a group of five or six people, and greeted them happily.

Qiu Tuan and others came to the No. 9 transport plane that was about to take off for a test flight.

He looked around the transport plane a few times with great interest, and then said to Wang Bin: "Mr. Wang! This No. 9 transport plane seems to be very different from the No. 9 transport plane we are using now!

Not to mention other things, just in terms of wing skin materials, it seems that it is no longer the original skin! There are also many parts such as the head of the machine that are different from the original ones. "

"Yes! Qiu Tuan, due to the weight of the tg-s002 turbofan engine, it is much heavier than the original engine of this aircraft. At the same time, it is also much stronger in terms of thrust. With the original wing of this aircraft The structure simply cannot bear the weight and thrust of the tg-s002 engine.

Therefore, we have carried out some reinforcement and modification to the overall structure of the aircraft, especially the key parts such as the wings, so that the wings of this aircraft can bear the weight and thrust generated by the tg-s002 engine.

At the same time, since the load capacity of this aircraft will be greatly improved after the engine is replaced, we have also carried out a series of modifications to the interior of this aircraft. The special materials of our Tiangong Technology are used.

Therefore, after the modification, the No. 9 transport aircraft weighed much more than the original one. In the original, the aircraft weighed about 30 tons, but after the modification, the empty weight of the aircraft was about 30 tons It has reached nearly forty tons, which is nearly ten tons heavier than the original one.

However, in terms of the maximum fuel load, after the transformation, although there is a certain increase, the increase is not much, and it is about 25 tons.

However, in terms of the maximum and maximum carrying capacity, it has been greatly improved, from the original 25 tons to about 35 tons.

In other words, the maximum take-off weight of this aircraft has reached about 100 tons at this time.

In addition, the practical ceiling of the No. 9 aircraft has been much higher than the original one, reaching 15,000 meters, and the maximum cruising altitude is 10,000 meters.

There is also the problem of the speed and endurance of the aircraft. In these two aspects, this aircraft has also greatly improved.

In terms of flight speed, before the modification, the maximum flight speed of this aircraft was probably less than 600 kilometers, but now the maximum speed of this aircraft can reach 800 kilometers, and at the same time, in terms of cruising speed, it has also reached 600 kilometers per hour. Finally, in terms of battery life, before the transformation, I remember that the maximum cruising distance of this aircraft was about 8,000 kilometers, but now after the transformation, the maximum cruising distance of this aircraft has reached about 10,000 kilometers.

It can be said that the No. 9 transport aircraft had a very big change in performance before and after the transformation. "Wang Bin, Qiu Tuan and others looked at the transport plane and introduced to them some level data of the No. 9 plane after its construction.

As for Qiu Tuan and others, after listening to Wang Bin's introduction, Qiu Tuan and others' faces were full of smiles. It was obvious that he was very satisfied with the performance of Tiangong Technology after the modification of this No. 9 transport aircraft. With a load capacity of 1,000 tons, it can already carry most of the army's armored vehicles. Even some light and medium tanks already have the carrying capacity. How could this not satisfy them.

You must know that this No. 9 aircraft is just a tactical transport aircraft, not a strategic transport aircraft. It can have such a carrying capacity. In terms of tactical transport aircraft, its carrying capacity is not only the strongest in the world, but it has also advanced in test flights.

So he said: "Mr. Wang, we are very satisfied with the transformation of this No. 9 aircraft by your Tiangong Technology. If this and the future test runs are successful, maybe we will ask you Tiangong Technology to help transform a batch of planes." Aircraft No. 9, after all, the transportation capacity of the old No. 9 transport aircraft is still not enough, and at the same time, it is also somewhat insufficient in terms of speed and range."

At the same time, he is also very much looking forward to Wang Bin's Tiangong Technology to help transform more No. 9 transport aircraft. After all, it has a carrying capacity of 35 tons and can reach a flight speed of up to 800 kilometers. If this is the case, the use of this transport aircraft will be great. , not only can be used as a medium and long-range early warning aircraft platform, but also can be transformed into a tanker.
