after an hour.
Following the test instructions from the tower, the H-20a slowly returned from the high altitude and then landed smoothly.
This test was a complete success!
All flight data are recorded in detail to meet the standards set before the test.
The on-site personnel watched the entire actual machine test.
After the H-20A came to a complete stop, everyone present stood up, applauded, and congratulated Zhao Zhiguo.
"Congratulations, Chief Engineer Zhao!"
"The success of the H-20A has filled the gap in our country's intercontinental navigation and patrol. Chief Engineer Zhao, you have made an indelible contribution!"
"In the future...when the H-20A flaps its wings, many countries will get restless!"
"..."
Zhao Zhiguo accepted their congratulations one by one and invited everyone to go to Factory 122 to rest and have a meal.
On the way there.
Zhao Zhiguo accompanied Ye Long and Li Yang.
Li Yang also congratulated.
"Chief Engineer Zhao, congratulations!"
"This important task was completed perfectly by Factory 122."
"The H-20A of the Dragon Kingdom is completely comparable to the B-2 strategic stealth bomber of the Eagle Country in terms of both endurance and stealth!"
Although some of its functions may still be somewhat different from those of the United States' B-2 and B-21 strategic stealth bombers.
But just now he took a quick look at the test data in various aspects, and the apparent gap between them is not that big.
however!
After hearing what he said, Zhao Zhiguo smiled bitterly and shook his head.
After many old professors and researchers walked away, he slowed down and explained with some bitterness.
"Mr. Li, you are praising me too much!"
"On the surface, the H-20A does not look much different from the United States' bombers, but there is one aspect that we cannot catch up with in a short period of time."
Hear the words.
Li Yang paused slightly and looked at him with a slightly surprised look.
Ye Long frowned even more.
Did Zhao Zhiguo hide some truth?
Ye Long asked in a deep voice.
"Chief Engineer Zhao, please explain in detail!"
If some mistakes occur due to Zhao Zhiguo's concealment, the consequences will be fatal.
Zhao Zhiguo obviously knew what Ye Long was worried about and hurried to explain.
"Assistant Ye, rest assured, this problem will not have any impact on the H-20A. It just makes it impossible for the H-20A to directly catch up with the level of the B-21 to a certain extent!"
Ye Long breathed a sigh of relief and his expression relaxed.
Li Yang took the opportunity to ask.
"Chief Engineer Zhao, I don't know what exactly this gap you are talking about is referring to?"
"engine!"
Zhao Zhiguo no longer concealed the truth and answered directly.
"engine?"
Li Yang looked confused.
"According to the relevant information they disclosed, the bombers of the United States use the F118-GE-100 turbofan engine, right?"
"And their engine, whether in terms of thrust, bypass ratio, fuel consumption, etc., cannot be compared with our WS-20."
"The difference in the engine shouldn't be that big, right?"
Li Yang did some research on the bombers of the United States.
Naturally.
He had some knowledge of the engine models used by their bombers.
same.
As for Longguo's WS-20 engine, he also read some introductions on the Internet and knew some data.
Compare the two.
The WS-20 engine of the Dragon Kingdom is far more powerful than the F118-GE-100 turbofan engine of the Eagle Sauce Kingdom.
Why does Zhao Zhiguo still say that there is still a huge gap in the engine?
Zhao Zhiguo smiled slightly.
"What Engineer Li said is correct, but this information is just past data."
"Although the United States has been on a downward trend in both military and economic terms in recent years."
"But a lean camel is bigger than a horse. They have not slowed down their research and development of high-end defense weapons and equipment."
After a pause, a trace of sadness appeared on his face.
“他们的b-2战略隐身轰炸机确实使用的是f118-ge-100涡轮风扇发动机，但他们的b-21战略隐身轰炸机，用的则是鹰酱国最先进的f135发动机。”
"And... there are reports that they even want to modify the B-2 to fit the F135 engine!"
In recent years, Longguo has achieved fruitful results in the research of aviation engines.
The WS-15 and WS-20 engines have been successfully developed and have good performance.
Just like the WS-20 engine used on the H-20A, its maximum thrust can reach 18 tons, and theoretically, it can even be increased to 18.3 tons.
The bypass ratio of its basic model can reach 1:6, and the improved model can reach 1:8.
The bypass ratio is an important parameter of a turbofan engine.
It represents the ratio of the air flow in the outer duct to that in the inner duct.
The larger the value, the higher the performance and the greater the thrust.
A breakdown of the world’s aircraft engines.
The ws-20 aircraft engine is enough to rank in the top three!
But even so.
The F135 aircraft engine of the United States is still a huge mountain.
It will take some time for Longguo to overcome this huge mountain in the field of aviation engines.
Li Yang was slightly surprised when he heard these words.
"F135 aircraft engine?"
"Chief Engineer Zhao, do you have the data on this engine from the United States?"
Zhao Zhiguo nodded.
"The relevant data of the F135 aircraft engine was accidentally leaked by the United States before, and it was quite detailed, but it was deleted later."
"But anyone with a discerning eye knows that the Eagle Sauce Country did this on purpose, clearly wanting to show off and strike a blow against other countries!"
He snorted coldly, and then briefly explained the data of the F135 engine.
"The F135 turbofan engine has a stable thrust of 18 tons, and there is still a lot of room for improvement."
"Thrust-to-weight ratio 10."
"The high pressure compressor air flow is 129.6 kg/s..."
The terrifying thrust-to-weight ratio of 10 means that the ratio of the weight of the F135 engine to the thrust it generates is very high, and its performance is extremely superior.
It is one of the turbofan engines with the highest thrust-to-weight ratio in the world!
and.
The f135 engine uses advanced turbofan technology and materials, which greatly improves fuel efficiency and reduces flight costs.
Simultaneously.
The F135 also has short take-off and vertical landing (STOVL) capability.
Its lift system includes the front lift fan, roll control nozzle and omnidirectional vector nozzle at the tail.
It can take off from short distances and land vertically.
After saying this, Zhao Zhiguo sighed.
"In fact, it is very good that our H-20A can achieve this level."
"Especially since we started late in the field of aviation engines and have no relevant experience."
"It is amazing that we have caught up with the level of developed countries in just a few decades."
"But as a scientific researcher and the chief engineer of the H-20A, I naturally hope that it can become better and more perfect!"
He shook his head, feeling a little regretful.
Research and development of aircraft engines cannot be achieved overnight.
It requires countless scientific researchers to spend a lot of time to overcome difficulties and make breakthroughs bit by bit.
He just hoped.
After a few years.
The fourth and fifth generation versions of the H-20A can use domestically produced engines that are comparable to the F135.
By then.
This is the complete form of the H-20A!
When Zhao Zhiguo was talking about the data of F135, Li Yang's consciousness had already sunk into the system.
After some searching.
He found an aircraft engine in the system's points mall.
After taking a quick look at its data.
Li Yang's eyes lit up slightly...
