After chatting for a while, everyone immediately started heading to the airport. Although the office building is right next to the airport, Wu Hao and the others still took a four- to five-minute shuttle bus to get to the site.
This actual flight test was not open to the public, so in addition to Wu Hao and the others, there were also some technical staff from the flight test center.
Wu Hao did not go to the measurement and control center with everyone, but came to the apron of the test flight site alone.
Here, he finally met Deputy Chief Designer Zheng Chengwei, whom he had not seen just now.
Seeing Wu Hao coming over, Zheng Chengwei, who was busy, immediately stepped forward to shake hands with him and said: "Mr. Wu, here you go."
Wu Hao nodded and said with a smile: "Mr. Zheng, you have worked hard during this period. How are you preparing now?"
Zheng Chengwei waved his hand and said: "No hard work, you have already set up the framework, we are just adding content to it.
We have completed a series of prerequisite testing links before, such as computer simulation, human-machine dialogue, and we even went on an aerial test flight platform for testing. The performance of this system has been excellent.
This real-machine flight test is mainly to equip our intelligent voice assistance system on the fighter plane, and then test its related functions during the flight phase of the fighter plane, and check the reliability of the entire system operation.
Especially when fighter jets are maneuvering at high speed, a lot of data is generated in an instant. How to correctly identify and read this data, filter it, and report important data first is the content of our important test this time. "
After hearing Zheng Chengwei's introduction, Wu Hao nodded. The content of this test is indeed relatively strict. When fighter aircraft maneuver at high speeds, they are relatively fast and will generate a large amount of dynamic data in an instant.
This requires the system to select useful data from these data, arrange them one after another, and prioritize the broadcast and processing of important data information.
When fighter planes are flying, high-speed maneuvers often appear when the fighter plane is in a dangerous state. For example, flying at ultra-low altitude, rolling at a large angle, or super maneuvering to tangle with fighter planes and avoid danger.
Therefore, for post-flight aircraft and fighter aircraft, every minute and second at this juncture is related to the life and death of the fighter aircraft and pilots. Therefore, the response speed of the system must be as fast as possible, and it must also be accurate and reliable. This undoubtedly has strict requirements on the performance of the entire system.
"There are many factors that affect system performance. In addition to the degree of optimization of the system itself, it is also related to the hardware of the fighter itself. For example, the performance of the processor equipped with the system is also related to the performance of the sensors that receive the data." Wu Hao said.
Hearing this, Zheng Chengwei said with a smile: "We have also considered what you said, so this time we chose the J-10C, which has the most outstanding performance among our domestic fighters, as our test flight platform.
This fighter is equipped with a brand-new domestic integrated fire control system and a digital fly-by-wire control system. It can be said that it is the second most informatized fighter among domestic fighters after the J-20.
We can't deal with the J-20, so we can only use this J-10C instead. In order to apply for this fighter jet, we spent a lot of effort.
Of course, we have spent a lot of effort to equip our system. The various sensors and related hardware equipment installed alone weighed 35 kilograms.
You know that the weight on a fighter plane is not increased casually. It not only affects the aerodynamic shape, but may also affect the aircraft's fuselage and flight balance. Especially on this kind of light fighter, the part in the cockpit is even more sensitive.
For this reason, I had to ask relevant aircraft designers for guidance before completing the relevant modification work. "
Although I don’t know what kind of sensors it is equipped with, it actually weighs 35 kilograms. Judging from Zheng Chengwei’s tone, they must have spent a lot of effort.
At this time, two test pilots wearing a blue flight suit, a military green anti-load suit, and carrying gray helmets walked over.
After seeing Wu Hao, the two men quickly stood at attention and saluted Wu Hao. Upon seeing this, Wu Hao quickly stepped forward and shook hands with the two of them.
"How's it going? Who's flying today?" Wu Hao asked with a smile, looking at the two test pilots with relaxed expressions.
Fan Yunlong smiled and said: "I will fly, and Cao Lei will be my substitute."
Wu Hao nodded and said, "I don't understand your auspicious words, so I wish you all the best and a safe flight."
"Haha, thank you Mr. Wu!"
Fan Yunlong smiled and said: "Your words are the greatest wishes for us pilots."
"Haha, originally I wanted to say it was a good trip, but after thinking about it later, it seems wrong. It seems that a good wind is not a good thing for you pilots and the aircraft." Wu Hao joked with a smile.
"Haha, we have heard this sentence a lot, and there are many leaders among them. But people always have good intentions. We can't refute it in public. Let's tell the troops they said.
So I can only comfort myself, let's just say it's a tailwind. There's no harm in the lift except that it's better than a crosswind. "Fan Yunlong laughed at them and said that although he was facing a test flight, he seemed very relaxed. More than ten years of test flight work made him appear very calm when facing such a task.
Ha ha ha ha……
Indeed, pilots also have their own taboos or words they don't like. For example, crosswind is a word that every pilot has a headache with. Especially when taking off and landing, the most taboo thing for airplanes is crosswinds. So in comparison, a tailwind is at least a little better than a crosswind.
And the headwind that we ordinary people dislike the most is the favorite of pilots. Because in a headwind environment, it is very beneficial whether taking off or landing.
"It's almost time, let's start getting ready." Zheng Chengwei looked at his watch and said to several people.
Fan Yunlong nodded, then stood at attention and saluted to Wu Hao and Zheng Chengwei again, and then walked with Cao Lei to the J-10C on the apron.
"When you come back, let's have a drink." For some reason, Wu Hao suddenly couldn't help shouting.
Fan Yunlong, who was walking towards the fighter plane, did not look back, but stretched out his hand and gave him a thumbs up.
Wu Hao smiled when he saw this, and then said to Zheng Chengwei: "Mr. Zheng, I will go to the measurement and control center first. Come over after you are done."
Zheng Chengwei nodded and said, "You go first. We will come over after the flight is over."
"good!"
Wu Hao arrived at the measurement and control center by car and had just sat down. I saw the fighter plane on the tarmac in the distance start, and then slowly slide towards the runway.
