Chapter 669: Follow the laws of science

Pilots need good physical conditions, so when selecting pilots, many sports specialties are given opportunities. As we all know, the cultural level of sports specialties is a bit poor.
Therefore, many pilots cannot be test pilots, because for test pilots, in addition to pilots, they must be engineers.
That's right, test pilots must have a college degree and must be at the level of flight engineers. Generally speaking, the test pilots themselves must be first-class experts in the aircraft design office.
Modern aircraft are becoming more and more complex. Despite the availability of advanced airborne test equipment and ground test equipment, the role of test pilots is still very important in assessing aircraft performance and monitoring the working conditions of aircraft systems.
In order to get acquainted with the aircraft as soon as possible, test pilots usually participate in the work from the initial stage of aircraft design, and give opinions on the design from the perspective of use and safety.
In the test flight, the test pilots must not only complete the flight actions safely as required, but also theoretically explain various flight phenomena, accurately report the flight situation, and put forward suggestions for improvement.
In the early days, it was all aircraft engineers who tested the flight by themselves, but as the performance of the aircraft continued to improve, the body of the flight engineer was no longer qualified, and special test pilots were required.
Although a large number of and perfect theoretical calculations and various ground tests have been carried out during the development of the new aircraft, there is still a certain degree of danger during the first flight and the flight of difficult subjects. When encountering abnormal phenomena, test pilots should be able to make accurate judgments and promptly and properly deal with them. Therefore, test pilots must have proficient driving skills, a high theoretical level and dedication.
In short, the pilot is selected from among the applicants for general recruitment, and the test pilot is selected from among the pilots.
Chen Rui is not only an outstanding representative among pilots, but also a test pilot.
An outstanding pilot will become a professional test pilot after about a year of study in the Flight Test Academy. This is what Chen Rui took.
Chen Rui is very young, but he has flown quite a few models. Chen Rui's experience in handling dangerous situations is also first-class, especially this new aircraft is controlled by wire.
Compared with the previous hydraulic control, the fly-by-wire control greatly facilitates the pilot's driving and gives the aircraft outstanding maneuverability. However, it is quite easy to crash if it encounters dangerous situations and improper handling.
Chen Rui has the most extensive experience.
Therefore, Chen Rui has been selected as the chief test pilot of the Raptors, but Chen Rui usually has a lot of things, not always staying in 6611.
Han State has a special flight test site and a special flight test institute. However, the test flight of the new aircraft does not go to the flight test institute immediately.
After all, the new machine cannot be transported by truck, right? The new aircraft is to be flown over, which means that the initial flight test subjects are all carried out in the aircraft factory. Only when the test flight is completed in the aircraft factory and the basic flight status is determined to be no problem. Fly to the Flight Test Institute for follow-up flight tests of complex subjects. If you can't even pass the first step of leaving the factory, it is better to enter the factory and return to the furnace.
Now, the Raptors fighters are finally about to embark on a new journey!
"Although this aircraft is an imitation, we still have to act in accordance with scientific laws. For example, we have to run on the ground before the test." Song Lao continued.
The experiment of the fighter plane must be carried out step by step. Now, although it is imitating an airplane, this is the first time after all.
It is different from Super Seven.
Super Seven, although it is very different from the J-7, after all, it is only an aircraft with a conventional layout. At the same time, it is mainly operated by hydraulics. Even when it first flew, it was the hydraulic system. Later, when Qin Guan got those electric systems, The modules needed for the transmission operation were finally replaced by the vertical telex.
Therefore, the test flight of Super Seven is not very complicated.
The Raptors are different. This is a duck-type aircraft, and it is also a statically unstable aircraft. This aircraft has never been seen before, or it is rare in this era. The earliest adopts a duck-type layout. The Griffin fighter jet of China did not flew for the first time in 1988. As it is now, it is definitely a large satellite.
Must follow objective laws.
When the fighter plane was developed, first it was a plane-in-the-loop experiment.
After the aircraft is produced, the aircraft is hydraulically powered and powered on, and then the test pilot sits in the cockpit. There is a visual simulation display in front of the aircraft, which can simulate the changes in the scene that the pilot sees when the aircraft is maneuvering. At this time, the test pilot pulls the control stick, because there is hydraulic pressure, so the rudder surface will deflect according to the design law, and the heaven and earth line displayed on the screen will also change accordingly. It is equivalent to the pilot sitting in the cockpit and flying according to the sight in front of him.
This is the first step. Through this test, it is checked whether the aircraft can be controlled normally. If you can't control it here, you definitely can't control it during actual flight.
As for this step, it can be omitted now, because there is already a prototype in front of him, and Chen Rui has also operated the prototype and flew into the sky several times.
This step can be omitted, but the rest cannot be omitted.
Next, there are low-speed, medium-speed, and high-speed taxiing tests. Generally, low-speed taxiing mainly depends on the flexibility of the aircraft on the ground, because it requires the fighter's ground taxiing capabilities such as turning radius and taxiing speed. At this time, the plane is a tricycle, the most expensive tricycle.
Then there are medium and high speeds.
The meal should be eaten bit by bit, and the work should be done piece by piece.
This first prototype was built and used for testing. At the same time, there will be a second and a third one in the future, which require static destruction tests to measure the strength of the aircraft, as well as multiple joint flight tests to speed up the progress and so on.
Imitation products should not have any omissions. If they come up and fly, who knows what will happen?
Song always looked at it with a scientific attitude.
Chen Rui nodded: "Well, this aircraft has been more than a year old. The progress of our 6611 Institute is really fast. Now, let me control it. This is our autonomous aircraft."
Super Seven has good performance, but the engine is constrained by others. The Han Guo Air Force is destined to not be equipped. However, the current Raptors are different. It will become the main force of the Han Air Force.
Although Chen Rui also admires Tomcats, it will take some time before Tomcats arrive. Now, let yourself be addicted to the Raptors!
Chen Rui looked at the fighter plane that was still being assembled, and his heart was full of expectation. At this time, Chen Rui, unaware that his brother-in-law would come here with more surprises.
