The first flight of the new aircraft factory is about to begin, and several important guests have already sat on the airport viewing platform: Ma Dade, Sultan, Wu Lao, and even Director Yang have specially arranged time to participate in the first flight.

The plane was towed out of the hangar by a tractor and stopped precisely on the runway. Now it's time to do the final test before take-off, again to make sure that the plane doesn't have problems with the sky.

Chief Engineer Yu is the chief designer of the new aircraft, and at the moment before the first test flight, he was still communicating with Yan Xiufu, the test pilot of the first flight, which is very necessary.

"Lao Yan, it's up to you for our new flight test flight this time, you have to believe that there will be no problem with our plane, you don't have too much pressure, I have already ordered it to go down." Today, you are the biggest model worker on Labor Day, and our celebration banquet has been prepared for you. ”

Dressed in a complete flight gear, Yan Xiufu was ready to go, just waiting for the first flight of the new aircraft to start: "Don't worry, Chief Master Yu, I have confidence in your design, I also have confidence in this new livery, and the most important thing is that I have confidence in this hundred and ten catties of meat." ”

It is not unreasonable for Yan Xiufu to be so confident, this is the first batch of veteran-level test pilots when the Republic formed a test flight force. From scratch, when the test flight unit was created, the first batch of test pilots accumulated the most abundant test flight experience, Yan Xiufu has tested the Jian-6jia, Jian-7 2, and now he has reason and capital confidence in the test flight of the new super Jianjiao-7.

Bidding farewell to the chief engineer, Yan Xiufu came to the runway, the plane's various take-off inspection work has been completed, only the ground power supply is connected to the power supply of the new aircraft, in order to ensure the power supply needs of the new aircraft, the aircraft's own backup power supply is quite precious, and there is no room for waste on the ground.

Circling around the plane, admiring the new machine's paint and new aerodynamic shape again, looking at this J-7, which is different from the one he has test-flown in, he silently made up his mind that he must fly this plane out safely and fly back.

Return to the boarding staircase. Make a final handover with the engineer in charge of the flight inspection of the new aircraft, sign his name, and indicate that the aircraft has now been taken over by the pilot.

After accepting the plane, Yan Xiufu shook hands with the project. Turning around and firmly lifting his feet, he stepped onto the boarding ladder and entered the cockpit, carefully experiencing the new cockpit interface and the comfortable capitalist flight sofa.

The flight avionics of the new aircraft have been greatly upgraded compared with the J-7, but most of the first aircraft has not changed. The only thing I experienced was the new seats. It feels pretty good, and it's no wonder that the Middle Eastern oil tycoons want to use this new chair.

Yan Xiufu has seen the data of the new seat, and it is said that the new seat can also help the pilot effectively resist flight overload. I just don't know how much help, and now the first flight is not able to test the anti-overload performance of the new seat, but I will definitely try to see if this seat is as powerful as advertised.

After packing up your things, checking the flight support system, environmental control system, wing rudder control, radio communication equipment, etc., and after there are no problems, the ground staff who are still on the boarding ladder to help start the aircraft are ready to start the engine.

Starting a jet engine is not like other piston engines, which can be started at the press of the start button. Jet engine starts with the auxiliary power unit first. After about 20 seconds, the green start in the cockpit lights up, indicating that the engine is about to start.

The "hiss" engine starts running with the help of auxiliary power. Then Yan Xiufu skillfully adjusted the throttle lever to adjust the engine to the slow position.

The information from the tachometer and thrust gauge shows that the engine is running smoothly.

Although the performance of the turbojet 7 engine is relatively backward, it is still relatively reliable in operation.

After the engine starts, it needs to wait for a while before taking off, and under the heating of the high-temperature gas, the air flow behind the plane has been deformed and distorted, so that it is visible to the naked eye, and the wave-like air flow is discharged to the back.

The test pilots wore oxygen masks and did not communicate with each other, but this did not interfere with communication. After a handsome generic gesture, remove the boarding ladder. After about ten seconds of force, the canopy was lowered, and the power cart on the ground was also disconnected from the aircraft.

Now the aircraft relies on itself to maintain autonomous operation, and only needs to increase the thrust of the engine and release the brakes, and the aircraft can taxi forward and take off. Ground crews and power trucks began to evacuate the runway. So as not to affect take-off and cause flight accidents.

Several leaders on the viewing platform in the distance saw that the cockpit cover of the plane had been lowered and the ground crew left, knowing that it was about to take off, they all picked up the telescope on the red cloth long table, carefully watched the first flight of the new aircraft, and resolutely could not let go of every classic moment of the test flight of the new aircraft.

It's not that the heads of the Saudi and Pakistani sides have never seen planes take off. Even these are those who have piloted planes to the sky, but they have never seen the first flight of a new plane. Now the test flight of the new aircraft naturally gives people a sense of freshness, this is a project invested by their motherland, which is like their own children, so they are naturally excited to have concerns.

The yellow and green paint is quite eye-catching, and you can't take your eyes off it at a glance, so you can only hold the binoculars with both hands and watch the first flight of the new aircraft.

Through the telescope, you can clearly see the test flight of the new aircraft, and even the movements of the test pilot in the cockpit. In about seven minutes, it's ready for takeoff, and pushing the throttle stick continues to increase the thrust of the engine.

The thrust of the engine gradually increased, the test pilot had released the main brakes, and the unrestrained aircraft was like a loose foal, although it did not have the explosive power of an adult mustang, but the heart to run fast was not weaker than that of an adult mustang.

The plane has already begun to taxi down the runway, starting at the end of the runway, getting closer and closer to the runway in front of the viewing platform, and there is no need to use binoculars to watch at this time.

Qi brushed down the binoculars, watched the plane glide in front of him, he hadn't seen it yet, after running a distance of about 600 meters, the speed of the plane reached 124 knots (230 km / h), this speed can already be pulled up, the test pilot did not hesitate to pull the control stick back a small stroke, and the instrument showed that the plane reached a 15-degree pull-up angle.

Now that the aircraft has reached the take-off angle, it is natural that the front take-off and landing will leave the runway, and the subsequent rear landing gear will not hesitate to leave with the front landing gear.

As the plane continued to climb to a higher altitude, it finally completed the takeoff.

"Okay, take-off, perfect take-off, that's a good sign."

After Director Yang's cheers, the crowd erupted in cheers, and the applause lasted for a long time. This is a moment when the majority of designers, manufacturers, managers, and all those who have worked hard for the development of new machines should be happy together.

The movement in the crowd comes and goes as fast as it goes. Now the main thing is to observe the first flight, and it is not too late to cheer or wait until the final safe landing.

Continuing to close the plane under the blue sky, the yellow-green paint is particularly eye-catching against the blue sky, and it is easy to see as long as you look up.

The first flight of the new aircraft does not need to retract the landing gear, nor does it need to fly at a high altitude, it only needs to fly around the runway a few laps after takeoff, and even a small overload maneuver is not needed.

Originally, it was a combat trainer with excellent maneuverability, but now it flew as elegantly and deeply as a civil airliner on its first flight.

What is the reaction of the crowd on the ground, Yan Xiufu on the plane does not know, now he only knows that the new aircraft flies quite well, and it is much more comfortable to fly than the J-72 that he tested last year, but the specific flight performance still does not seem to be out of the range of the J-7, as a high-level trainer improved by the J-7, this is undoubtedly qualified.

When the flight altitude required for the first flight is reached, the joystick is pushed again, and the aircraft is leveled and enters the level flight state. (To be continued.) )
