The big Tomcat fighter plane parked on the runway at this time each rudder surface moved back and forth according to the steps, and the rear sweep wing was retracted and deployed again, giving people a feeling of transformation transformation.

As the throttle is increased, the airflow of the engine is getting stronger and stronger, and the engine emits a unique low roar of the aero engine designed and manufactured by Yonghang Aviation Technology Company.

Because Yonghan Aviation Technology Company uses absorbing materials, the structure of the core aircraft is also different, and the sound emitted is different.

At this time, the tail nozzle began to shoot out powerful blue flames, and the fighter taxied faster!

Feeling the power of the engine, Duan Qinghong was immediately stunned, this time the engine was much larger than the turbofan engine tested earlier!

Before he could pull the control stick to raise the nose of the plane, he felt that the fighter plane, which was more than 20 tons, was about to fly

The engine power of Yonghan Aviation Technology Company is too strong!

Duan Qinghong immediately slowly pulled up the control stick, and when he just lifted the control stick, the nose of the fighter began to rise, and the angle between the entire fuselage and the ground began to grow larger and larger.

"The take-off distance is so short?"

Seeing that the big Tomcat heavy fighter took off less than four hundred meters, Jarrad also said in surprise.

This is the world's top heavy fighter, with a full load of more than 30 tons, and such a short take-off and landing distance proves that the power of the engine is very strong!

"The aero engine on this aircraft is an improved version of our company's Hengshan 4A, and the thrust has been increased to more than ten tons compared with the previous engine, and the maximum thrust has been increased to sixteen tons. ”

Yang Jie said with a smile: "This is our company's internal facelift, has completed thousands of hours of technical verification tests on the high-altitude platform, through more than 1900 hours of cyclic acceleration test, the core of this engine in the two tests caused by the replacement rate, air parking rate, thrust loss rate are 0, indicating that the engine has achieved the purpose of improving reliability." ”

He continued: "The two experiments were full of throttle transitions 172847 times, afterburner ignition 19,308 times, engine acceleration 76,738 times, which is equivalent to 18 years of field use. In addition, we have simulated the working conditions of the engine at various altitudes and temperatures, and have also conducted high-cycle fatigue tests, and the performance of this engine has made the company very satisfied. ”

Yang Jie said with a smile: "In the past, everyone knew that our domestic aviation industry had heart disease, and this heart disease has always been incurable, but now I can proudly say that every engine in our company is reliable." ”

In order to speed up the R&D speed, Yonghan Aviation Technology Co., Ltd. relies on technical R&D personnel to work overtime and constantly do technical verification, and the need for design, R&D, manufacturing and delivery cycle in foreign countries has been compressed to less than two years.

However, these engines are very reliable after passing these rigorous technical verification tests, and the first batch of engines delivered to Hongdu Group has flown for hundreds of thousands of hours without a major accident in the air.

Moreover, these engines have been flying for more than four years and have entered the time for the first maintenance, and the engines of Yonghan Aviation Technology Company at home and abroad are very satisfied, because the quality is the same as that of Rolls-Royce and Pratt & Whitney, which are very reliable and more fuel-efficient.

Hearing this, Zhang Kelong and Shen Jianhong both looked at Yang Jie: "This improved engine should be used for our own fighter jets!"

"The size of this engine is different from the size of the engine compartment of the domestic fighter, even if it is carried up, it will be overhauled, which is equivalent to redesigning an engine, they may not be willing!"

Yang Jie smiled and said.

What he said was also the truth, and Shen Jianhong and Zhang Kelong also nodded.

In fact, these domestic aircraft manufacturing companies have their own small abacus, even if the previous four aviation companies are integrated into one, there are also their own barriers between them, and the fuel cell power package of Huaxing Group has gradually replaced the power system of helicopters and warships, Huayuan Group and several companies produce diesel engines, turboshaft engines, The turboprop engine company began to produce fuel cell power packs in an all-round way, snatching a very large market from the original four major aviation development group companies, and now these four group companies have also begun to produce fuel cell power packs, which have to purchase stacks and control systems from Huaxing Group companies.

Now the domestic aviation engine market is only left in the turbofan engine market, China Aviation Development Group is also quite depressed, the domestic aviation market pattern has been completely turned upside down by Huaxing Group Company.

At this time, the energy of China Aviation Development Group has been shifted to the development of large bypass ratio turbofan engines on the basis of the mature Taihang engine core engine to enter the civil aviation engine market.

In order to ensure that the aero engines of China Aviation Development Group have enough carrying platforms, such as the Su-27 series produced by Shenfei Group, will not use the engine of Yonghan Aviation Technology Company, and the First Aviation Group Group also hopes to use Taihang engine.

Yang Jie is naturally very clear about these things, he does not force this, his eyes are staring at the overseas market, now the J-9, Xiaolong, K8, L15 and Eagle and Rainbow series UAVs have become the golden sign of exports, last year Yonghan Aviation Technology Co., Ltd. exported the number of small bypass turbofan engines reached more than 2000 units, and the number of exports accounted for most of them.

As for the civil aero engine part, Yonghan Aviation Technology Company sold more than 1,000 units last year, almost more than 3 billion US dollars in revenue.

Several of the engines sold by Yonghan Aviation Technology have accumulated hundreds of millions of flight hours without a single failure, and have begun to gain the trust of many airlines.

AECC still has a long way to go in this regard.

Yang Jie smiled and said to Zhang Kelong and Shen Jianhong: "When the test flight is completed, we will also provide a prototype to the domestic naval aviation force, and if we are satisfied, we will purchase more." ”

Shen Jianhong glanced at Jarard on the side, and then whispered to Yang Jie: "There is no opinion on the side of the rest country?"

"The Sabbatical side will not care about this, besides, we have figured out this big tomcat, and the initiative is in our own hands. ”

Yang Jie said.

"Hongdu Group launched the J-9, and now you want to make a big tomcat, you are going to let us pick and choose!"

Shen Jianhong said.

"In the past, there was no choice, but now the army has to choose. ”

Yang Jie said with a smile.

"Okay, when the test flight of this big tomcat is completed, our navy will be the first to conduct a test flight. ”

Shen Jianhong laughed.
