The first flight of the plane is a ceremonial event, as long as it can take off smoothly, it is almost a third of the mission progress completed, and although the take-off of Form 4 has experienced a small episode, its essence is that there is no problem, and the take-off process is successful. Pen ~ fun ~ pavilion www.biquge.info

Speaking of which, although the first aircraft is "patchwork" this time, and even the entire avionics system is transplanted from the J-18, but objectively speaking, this set of avionics system is actually advanced enough, even if it is a top F-22 fighter this year, its avionics display layout is not also a traditional design? Compared with the current J-18 and Zhongsi avionics, in fact, there is really no cross-generation gap.

Therefore, the first aircraft of Form 4 should be regarded as one of the few first aircraft that can be equipped with a complete avionics system, you know, when other types of military aircraft make their first flight, there are really few that have a complete avionics system, most of them as long as they can meet the needs of flight.

The avionics system is relatively mature, and the pilot should be more assured when he first flies, and the mature and reliable avionics system can make the pilot more clear about the operation of the entire fighter, and the display is more intuitive perception, not to mention that the first flight is no longer as simple as in the past in terms of ground support.

The appearance of the first flight command and control center on the ground has made the first flight of the fourth flight of the middle school very different from the first flight of the previous aircraft, compared with the traditional military fighter flight test, this time it has been greatly improved, at least in terms of ground support, the flight tracking and control built here in Hongdu is even similar to the existence of the aerospace command and control center in the future.

The entire flight TT&C center can receive the flight data measured by various sensors on the test aircraft in real time, and realize data analysis through the supercomputer of the TT&C center, which can simulate the flight parameters of the aircraft in almost real time and put them on the large screen of the TT&C center, which also allows everyone in the TT&C center to see the simulated 3D animation flight state of the first aircraft, which is definitely a huge progress.

In the past, if you want to see the 3D flight animation simulation of the fighter, it must be after the fighter lands, manually extract the flight parameter data of the aircraft, and process the flight parameter data to obtain the 3D flight data simulated by the computer, but now it can be simulated in real time during the flight of the aircraft, which is almost unimaginable in the past.

All this is a qualitative change brought about by technological progress and tons of funds smashed out, in the past, it was difficult to send it in real time when entering and storing data, even if it can send data, it is also a great problem in terms of transmission, and this time, it is through the accompanying special aircraft MPC-75 to do signal relay to achieve data transmission efficiency amplification, so as to accelerate the transmission speed.

Of course, the special TT&C aircraft modified by MPC-75 also carries a large number of data monitoring loads, and in the process of accompanying flight, it can also monitor a large number of flight data of Form 4, as a supplement to the sensor data of Form 4 itself.

The 3D flight animation simulation of the first aircraft displayed on the large screen can clearly and intuitively show the flight attitude data of the fighter, but this is far from enough.

Under the large screen of the TT&C center, there are many rows of TT&C stations in an arc, and hundreds of PC computers are constantly displaying and refreshing various data, and these data are no longer flight attitude data.

These computers have corresponding staff to monitor and analyze data, each person is absolutely responsible for the data they are responsible for, as long as the data displayed is abnormal, the staff can get the news at the first time, and respond immediately.

At this time, Yang Hui also happened to take several leaders together and walked into the busy flight tracking and control center, and introduced in a whisper, for fear of disturbing these staff: "This is our flight tracking and control center, the entire tracking and control center can measure and control all the flight data of the entire first aircraft in real time, our pilot in the sky is flying alone, but the ground tracking and control center has hundreds of people to escort it, we guarantee that we can monitor all abnormal conditions, and nip abnormal problems in the bud at the first time." ”

In 1996, the aerospace command and control center located in the imperial capital was established, and now it is only in mid-to-late 1997, and there is still a long time before the space command and measurement and control center is completed and operational, and the leaders have naturally not seen this kind of battle in the measurement and control center.

This time, AVIC Southwest has made such a large scale, which is definitely eye-catching, and its height is simply blinding everyone's eyes. On the other side, accompanied by the deputy commander-in-chief of the TT&C mission, he also gave the TT&C Center's answer to the TT&C mission at the right time, and made a relatively brief report.

"According to the report, our TT&C center has successfully analyzed the reasons why the aircraft flew off the runway ahead of schedule when it took off just now: under the same power output of the aircraft, the on-site head-on wind data and crosswind data have a moderate increase in wind level compared with our expectations; The overall weight of the aircraft is 6.7 percent lighter than the normal weight; The wing lift coefficient remains within the normal range, but the lift data of the fuselage lift body exceeds our wind tunnel test results, providing more additional flight lift; The comprehensive calculation and simulation ends with the aircraft reaching the take-off speed in advance at XXX/s, which is consistent with the on-site flight data of our aircraft. ”

The report is very brief, but all kinds of terms and data are still a little scratching their heads in the eyes of non-professionals, and it is necessary to be unclear, but everyone can still hear it roughly, that is, this measurement and control center is very awesome, and it can find out the cause of the accident in a short time, which is almost impossible in the past.

The big leader, who was still a little shocked in his heart, also smiled at this time: "Very good, you guys are very good, you must make persistent efforts, you must make persistent efforts to catch up with and surpass the international advanced level!" ”

Yes, this big leader must not know that this flight tracking and control center is also absolutely tall in the world, as strong as Boeing, Loma and other first-line big names, and it has not been a few years to use this thing, and those slightly backward aircraft development units such as Dassault, Sukhoi, MiG or something, now absolutely cannot afford to use these high-end equipment drops.

At this time, the measurement and control center also sounded the monitoring data analysis report of various departments in real time: "Propulsion system; The air flow is normal; The engine speed is normal; Cooling is normal, oil is normal....."

"Pneumatic systems; The surface pressure difference is normal; Eddy current control is normal; Normal ...... of aerodynamic impact energy of wing roots"

Flight control system....

Avionics system....

....

At this time, a discordant voice came: "The propulsion system reports that the flow difference between the two sides of the air intake is slightly exceeded!" ”

As soon as the problem was reported, the flight attitude monitoring system department gave a possible result: "The aircraft attitude turns left and deviates, which may lead to the above problems." ”

Immediately the environmental monitoring came again: "The crosswind on the site is X, which can lead to the above problems. ”

The two departments gave the reasons that may have caused the flow difference between the two sides of the inlet tract to exceed the standard, and it happened that the air flow difference of the inlet tract on this side was restored: "The data is back to normal, done!" ”

Looking at the big screen again, the first plane has just been adjusted from yaw to straight flight, which indirectly proves the cause of the previous small problem, with a complete real-time data measurement and control capability, it can be said that the problem comes and goes quickly.
