After reading the book, the address of [Wanbenshen Station]: Avoid the pain of chasing books!

A few days later, Yang Jie appeared at a test flight base in the northwest region.

At eight o'clock in the morning, there were already quite a few people at the airport, and some technicians and inspectors from the aircraft factory of Xifei Aviation Group were conducting the final inspection of the aircraft.

Wang Yonglin, Konstantin, Liu Fuping, and the senior management of Yonghan Aviation Power Technology Company were also invited to watch the test flight of the Y-8K.

As soon as he arrived at the airport, he got off the car, Yang Jie saw the Yun-8K in the distance, this was the first time Yang Jie saw the Yun-8K, the last time Yang Jie went to the Yun-8K aircraft factory, he saw this transport plane, which was still a semi-finished product and was not completed.

Yang Jie was about to take everyone to take a closer look at the plane, when he saw several warrior military off-road vehicles driving over in the distance, stopping not far in front of Yang Jie and others, and a large group of people got out of the car.

These people are all soldiers, there are naturally a lot of colonels and colonels, at least a dozen people, among these school officers, there are also a few generals, the stars are shining, Zhang Haiping and the other two military bigwigs have also come over, which shows the importance attached to this Yun-8K test flight.

Yang Jie walked over quickly, also greeting these military bigwigs.

"Amazing, your company has produced the Kunlun large bypass turbofan engine in less than a year and completed 300 hours of testing on the ground. ”

Zhang Haiping shook hands with Yang Jie and said.

Yonghan Aviation Power Technology Co., Ltd. in Zhuhai Air Show last year after the completion of the exhibition soon assembled a prototype for a large number of ground tests, in the middle of several months of design modification, the prototype passed 300 hours of ground testing, now there are two small batch production of turbofan engines in the high-altitude platform for a variety of high-altitude test tests.

The military couldn't wait, and directly purchased eight units in the past, of which the Y-8K designed and produced by the West Aircraft Aviation Group Company carried two, the other one was used for backup, and the other five were ready to be used on an Il-76 for testing, and now the West Aviation Group is still nervously refitting.

Yang Jie said politely: "I want to thank the leaders for their support, otherwise we would have to find other flying platforms." ”

Zhang Haiping said with a smile: "Such a good engine, we can naturally take care of it." ”

Several military bigwigs also couldn't wait to walk in front of the Yun-8K plane.

This Y-8K is a transport aircraft redesigned by Xifei Aviation Group Company after digesting a large number of aircraft data obtained by Yang Jie and Huo Xiaotian from Ukraine, and its volume is one size smaller than that of Il-76, but the load capacity has reached 40 tons, which is much larger than the previous Y-8.

The design style is still influenced by the Soviet Union, and the aerodynamic layout is quite similar to that of the Il-76.

Zhang Haiping glanced at Liu Zhiping, the chief designer next to him: "This Yun-8K is very similar to the Il-76!"

"Chief, the aerodynamic layout of the Il-76 is very mature, in fact, we also design a new aerodynamic layout, but it is not yet mature, so for the time being, we will learn from the aerodynamic layout of the Il-76. ”

Liu Zhiping said: "However, we have made certain improvements and upgrades on the basis of the Il-76, the flight control system and electronic equipment have been upgraded, the cargo compartment is wider and more solid, and our many wheeled infantry fighting vehicles can be loaded into it, which can be said to be a new transport aircraft." ”

He glanced at Yang Jie and said: "In particular, the maximum thrust of the Kunlun turbofan engine provided by Yonghan Aviation Power Technology Company has reached 19 tons, which is six and a half tons more thrust than the D-30KP-2 engine developed by Russia's Perm Aero Engine Research and Production Consortium! With such a high-thrust engine, not to mention the Yun-8 series, even a larger type of transport aircraft can do the job." ”

Zhang Kelong said happily: "In the past, the Yun-8 could not be loaded with infantry fighting vehicles, which was a huge hard injury, and our military's airlift capacity was also greatly reduced.

Zhang Haiping is not a technical cadre, and he knows far less detailed and in-depth than Zhang Kelong, pointing to the two engines on the wings and saying, "This is the Kunlun turbofan engine, right?"

Liao Dong of Xifei Aviation Group hurriedly said: "Yes, chief, the maximum total thrust of the two Kunlun engines is 38 tons! It is larger than the thrust of the Pratt & Whitney PW2040 installed on the American C-17, which gives the Y-8K a very excellent flight performance and load capacity." ”

Zhang Haiping and several military bigwigs all had smiles on their faces, and they all couldn't wait to walk in front of one of the motives.

Because the engine is installed in the engine cabin, I only see the fan blades, but the fan blades are very beautiful. Not only the titanium alloy wide-chord hollow blade, the blade surface has a special coating, the blade presents a beautiful black, and the whole disc of fan blades also has a beautiful clockwise rotation pattern, which looks more beautiful and exquisite.

"Yang Jie, this moving blade looks very good. ”

Wang Yonglin on the side saw Yang Jie giving him a look, and hurriedly introduced it, focusing on the fan part. Including these fan blades.

"It turns out that this is a titanium alloy wide-chord fan blade, I have heard of it, and today I finally saw it. ”

Another military boss said happily.

These bigwigs looked at the fan blades in front of the turbofan motor with great interest, and then turned to the tail spray position of the motor and looked inside.

"Mr. Wang, your Kunlun turbofan engine is really not small. ”

"The Kunlun turbofan engine belongs to a medium-sized turbofan with a diameter of one and a half meters. ”

Wang Yonglin said.

"Yang Jie, does your company have any plans to develop large and larger turbofan motors?" Zhang Haiping looked at Yang Jie and asked.

"Ladies and gentlemen, our company is not very interested in turbofan engines with larger bypass ratios, we are more interested in electric propulsion turbofan engines. ”

Yang Jie said: "This is the key project of Yonghan Aviation Power Technology Company, and I don't want to keep running behind the butts of these European and American countries, it doesn't make much sense." ”

"Electric propulsion turbofan engine?" Zhang Haiping was stunned.

"Yes, I'm working on a new type of electric propulsion turbofan engine that will be powered by fuel cells instead of aviation fuel. ”

"It's too risky, isn't it?" said Zhang Kelong, surprised.

"Aero engine is a high-risk and high-investment industry, and we are also prepared for the possibility of failure in research and development, but if it can succeed, it may change the pattern of the entire aviation industry, so that our Huaxia country can achieve corner overtaking. ”

Yang Jie said: "The United States is too strong in aero engines, and our Huaxing Group is a leader in fuel cells and motors, which has also laid a very solid technical foundation for us to develop new engines." ”

Zhang Haiping nodded and said: "Your company is really maverick and very innovative, but your ideas are very good! If there is any progress, you must report to our military." ”

Yang Jie also agreed.

The big hatch behind this Yun8K is open, also for the convenience of everyone to visit.

Yang Jie and the others walked into the cargo compartment from the open hatch.

Zhang Kelong had seen Yunba's warehouse before, and when he walked in, he obviously felt different.

Liu Zhiping also introduced at this time: "Chiefs, the improvement and upgrading of the Yun-8K transport aircraft is mainly the upgrade of the motive and cargo hold, this cargo compartment has been widened by 61 cm on the original basis, and the two titanium alloy supports that run through the entire cargo hold with a width of 3o cm have been added, and our infantry fighting vehicles can come in from the large hatch at the tail and then stop in this position......"

After the improvement, the Y-8K transport aircraft can carry an infantry fighting vehicle or two 1O5mm light howitzers, and its transportation capacity has also been greatly improved, which is also a great blessing for the current military.

Everyone looked at the cargo compartment and then went to the cockpit.

The cockpit has also been upgraded, using a lot of digital displays, the flight control system has also been upgraded, and Doppler radar has also been installed.

Many of the electronic equipment used in this Yun-8K, and a large part of the key chips and devices are provided by Huaxing Group Company.

After looking at it, the military and others are quite satisfied with this, not to mention anything else, this Yun-8K has been reborn in the avionics system and power system!
