The painting design is completed, followed by spraying and coloring, which is the new machine must find time in the hangar, and there is naturally no time to do painting during the day, and Yang Hui has the opportunity to paint the new machine at night.

Speaking of the coating of the new machine, the background color of the new machine is originally yellow, this is because the aluminum alloy skin is sealed with potassium dichromate solution, and the anodizing after closure is yellow, which is corrosion resistant.

Since the skin is already yellow, it is easy to do, just apply green paint where necessary, which is a relatively small amount of work, and can barely be completed in one night's work.

From the evening to the early morning to hand over the new machine to the engineer who came to do the final inspection, Yang Hui has been paying attention to the scene, because the new coating has not yet dried, Yang Hui is still staying at the scene after the new machine is handed over to the engineer, beware of accidents.

Fortunately, Yang Hui did it very carefully, and the other engineers saw such a handsome painting and also restrained their large-scale movements, and there were no accidents before the painting was completely dry, which was the most satisfying for Yang Hui.

After the painting was completed, Chief Engineer Yu came to visit the new machine, and was extremely satisfied with this new coating, and even thought that such a coating could be promoted nationwide, which was beautiful and practical, and there was no reason not to catch fire.

"Yes, this livery is really good, why didn't our previous livery look so good? This is really a big loss, and the new machines in the base will be painted like this in the future, and our base can call the shots. ”

Of course, the new livery must have a new atmosphere, and the test pilot must now adapt to this livery in advance, otherwise it will not be good to suddenly see the new livery of the new machine and cause too much mood fluctuations. Test flight is a high-risk industry, not only for the aircraft, for the weather, but also for the pilot's mental quality on the day of the test flight.

Theoretically speaking, when the pilot tests the flight, it is not possible to have too many emotional fluctuations, and it is necessary to do a real heart, but this is completely impossible, no matter how much attention is paid to the test flight of the new aircraft, the test pilot cannot be without emotional fluctuations. It's just a small area.

Then to control it to a small extent, it is necessary to exclude as much as possible all situations that may cause mood fluctuations in the test flight institute, and it is completely necessary to let the test pilots see the new livery in advance.

When Chief Engineer Yu brought the test pilot, Yang Hui still felt that this one was a little familiar, and he understood it after thinking about it carefully. Isn't this the test pilot of the new J-7 that was forced to land when Yang Hui first arrived at the base a year ago, and now this test pilot didn't expect to be able to return to the blue sky again so soon, I have to say that the test pilot's mental quality is excellent, which must be admitted.

Just walked into the hangar. The test pilot was excited, such a new livery is the most suitable livery for the new aircraft, only such a beautiful and eye-catching livery can match the beautiful face and figure of this little beauty.

Excitedly, I walked around the new aircraft several times, and then slowly and carefully observed the special features of the new livery, from the nose to the tail, from the main wing to the aileron, and finally the flat tail and vertical tail. Even in order to see the paint shape of the belly, the test pilot did not hesitate to lie flat on the ground on his back and observe carefully.

After a long time, I finally imprinted this beautiful livery in my mind. At this time, he tentatively stretched out his hand, wanting to touch the beauty who had changed into new clothes, but suddenly his hand stopped in mid-air, and turned his gaze to Yang Hui, what question did he want to ask.

Nodding affirmatively, Yang Hui said at the same time: "No problem, now the paint has been dry, there is no problem to touch it, the official test flight three days later, it will definitely not drop the chain on the paint, you can rest assured." ”

got Yang Hui's affirmative answer. At this time, I continued to put my hand on the new machine, and finally I could touch the beauty who had changed into new clothes, and I was still guaranteed for a long time.

"Chief Engineer Yu, as well as Secretary General Yang who designed the pneumatics and coating of the new machine, you can rest assured. Now that I've changed to a new livery, I feel like I'm more motivated to test fly. This test flight will definitely go more smoothly, how can I not let this beauty make the slightest mistake, the person is in the machine. ”

This is a fine tradition that has been retained by the Air Force of the Republic since the beginning of its establishment, and this is not recommended in the high-risk test flight out of the principle of protecting the test pilots. However, if the problem can be flown back technically, it is a very important clue to the troubleshooting of the new aircraft.

This time. Yang Hui will not say anything about safety is important, this is disrespectful to the test pilot, and the behavior of the test pilot is to do every little thing on the ground, and everything must be taken into account, so as to ensure that there will not be any new aircraft with problems flying into the sky.

"Okay, we'll take care of every little detail on the ground to make sure the new machine is in the safest condition. Our new model airplane has been in test flight for many hours without any problems. ”

Speaking of model flight test, this has to mention the trick of a new invention: that is, to scale down the new aircraft and create a model airplane for test flight.

Flying with model airplanes is better than a full-scale free wind tunnel test in a wind tunnel, and flying in complex skies is much more realistic than flying in a wind tunnel.

Now, that is to say, there is a new product in the base's model aircraft products: Super Jianjiao VII. I have to say that this time it was an unexpected surprise, absolutely beyond the expectations of Yang Hui, the founder of the jet-powered model airplane, and it seems that this can also be said to be the technical support of civilian products for military products.

Speaking of model airplanes At this time, a model airplane of a new aircraft flew outside the hangar, and the sound still sounded quite 'sensitive', at least Yang Hui felt that it was time to limit the flight altitude of the model airplane? It is indeed inappropriate to fly too low, and the noise of aircraft disturbing the people has always been an international problem.

For the new machine, the whole base is eagerly looking forward to it, this new machine is the key to whether the base can rise, if this project fails, I am afraid that the base will completely sink, life and death are between this project.

In view of these, the base invited leaders from all walks of life who were concerned about the new aircraft project in the first flight of the new aircraft, and as expected, most of the leaders were in place, and Pakistan and Saudi Arabia were also in place at the same time.

May 1 is a special day, not only a festival for the vast number of working people, but also the first flight day of new aircraft, and this day is specially chosen by the base.

The slogan shouted loudly: "Gifts for the broad masses of working people, gifts for glorious labor"

May 1st wind and sunshine, Yunnan-Guizhou Plateau clouds thin, visibility is quite good, such weather is suitable for the first flight of the new aircraft, the same design, early in the morning the new Yang Hui and the viewing group arrived at the airport quietly waiting for the first flight of the new aircraft, this is Yang Hui waiting for nearly a year of excitement.

Test flight is a high-risk job, test pilots not only need to be courageous, but also have sufficient knowledge of aircraft engineering, if there is no these, once there is a special situation in the flight, it is a tragedy of plane destruction and death.

The new factory prototype is used to test whether the aircraft can fly, whether there will be major flight hazards when flying, and in general, the factory test flight is to test the performance of the aircraft itself.

As for the rest of the flight data, whether it can complete the tasks required by the army, and the performance of combat avionics equipment will be left to a later date. (To be continued.) )
