"I know the way, I know the way......," Lin Hongfei nodded again and again, at this time, the old man Ma needs to put all his energy on these instruments and equipment in front of him, to put it bluntly, it is, "You Lin Hongfei hurry up and stay where you are cool, don't get in the way here!" For this accusation, Boss Lin is still willing to be happy, not Boss Lin's skin, but Boss Lin knows that this kind of thing can't tolerate a trace of mistakes, if something happens because of his indiscriminate opening in the middle, or if he doesn't notice something, the old man can have the intention of killing, "Old man, you are busy, I'll watch here." ”

"Hmm......" Lin Hongfei's attitude made Old Man Ma feel a lot more comfortable, and handed him a telescope, "Mr. Lin, use this ......"

……………………

"The system has been inspected, all subsystems are in order, and permission is requested to proceed with the first stage of the ground taxiing test." There was a ......rustling of electricity in the hand in front of Old Man Ma, and then a voice sounded.

"Approved, permission to proceed with the first phase of the ground glide test." Almost using all his strength, the old man shouted to the hand.

"Yes, the first stage of the ground glide test is approved!" With a firm voice from the microphone, the Beijun 100 plane not far away in front of everyone released the brakes, and the plane began to move on the ground, slowly starting to accelerate and accelerate......

Lin Hongfei held his breath, his eyes stared at the plane in front of him, although he couldn't tell whether the attitude of the plane that was taxiing was right or wrong, but he was nervous in his heart, extremely nervous.

Under the gaze of everyone, taxiing on the ground at a speed of about thirty or forty kilometers per hour, the attitude of the plane was stable. The tip of the wing is gently swaying up and down rhythmically, it seems that everything is very normal, when taxiing at this speed to the end of the runway, the plane began to slow down and turn, and let the plane make a 180-degree U-turn in the steering area, and the nose realigned with the direction when it came, not to mention the professionals who involuntarily began to cheer, even Lin Hongfei, a guy who doesn't know much about aircraft, the whole process is very smooth.

"Good! It's smooth! The old man's voice trembled with excitement, "How is the sense of control?" ”

"It's smooth, and the control system executes the driver's intentions perfectly. Very perfect design. In the hand clenched in the old man's hand, the "captain" of one of the two test pilots did not hesitate to praise the North County 100, "I personally think that the second stage of the medium-speed ground taxiing test can be carried out, is it allowed?" ”

Low-speed ground taxiing is primarily used for the distance between the aircraft entering and exiting the boarding area and before entering the aircraft's take-off runway, and is the minimum standard for aircraft design. Now the "captain" is going to test the medium-speed ground taxi, after entering the runway. The speed range when accelerating to around 150 km/h. According to the previous plan, if everything goes well in the first stage of the ground taxiing test, the second stage of the ground taxiing test can be carried out.

The old man squeezed his hand tightly and muttered: Today's task has actually been successfully completed, and the second stage of the gliding test will start in a few days, is it necessary to do it now? If it doesn't work out. The impact on the future of North County 100 is not ordinary!

But the old man knows better that if this medium-speed ground gliding test can also be successful, the benefits are self-evident: when it was originally just a low-speed ground gliding test, it can even be done in a higher-level subject. What does this mean? This shows that this aircraft is very successful, very successful, not an ordinary success!

Although the TU-134B itself is a very successful aircraft, and the huge sales have proven this, it is not a problem to directly test the second subject, but if the Beijun 100 developed on the basis of the TU-134B is a brand new aircraft, it is estimated that no one will object: not only the avionics system, but also the wings have been replaced, and the overall aerodynamic layout and structure of the aircraft have undergone tremendous changes, do you dare to say that this is not a completely new aircraft?

Thinking of this, Old Man Ma was really a little hesitant, and he subconsciously set his eyes on Lin Hongfei.

"How sure are you?" Old Man Ma's worries and hesitations Lin Hongfei naturally knew it, he groaned for a while, and asked in a low voice.

"At least seventy percent, but not ......"

"Seventy percent? A lot, unless our plane has major safety hazards, otherwise the medium-speed taxiing can pass no matter what, if you can't even pass the level of medium-speed taxiing on the ground, this plane will be a time bomb in the future," Lin Hongfei nodded heavily, "Let's slide." ”

"That's right, you can't pass this level, and it will be a time bomb in the future!" Old Man Ma agreed with Lin Hongfei's words, nodded heavily, and pressed the call button of the hand microphone hard, "Permission to carry out the second stage of the medium-speed ground glide test!" ”

What the? Doing the second stage of the mid-speed skating test now? The test testers who didn't expect Ma Lao to agree were all stunned, and looked at Ma Lao in surprise: "Mr. Ma? ”

"Check the equipment and systems again to confirm whether they have the conditions for the second stage of ground gliding test," facing everyone's eyes, Old Man Ma said heavily, "All units pay attention, pay close attention to the changes in various data!" ”

"Yes, the equipment will be inspected to determine if it is ready for the second stage of the ground glide test." The test pilot's voice also followed, "The engine is working properly, the booster system is working properly, the communication system is working properly, ......"

Is it really going to be a second stage of ground gliding test?! Test two projects at the same time?!

After a short pause, the test seat boiled!

Lin Hongfei only felt that he was almost suffocating.

He thought that he could face this matter relatively calmly, but when all this happened in front of him, he realized that everything was not as simple as he thought, and in the face of this huge pressure, he would still feel scared and frightened, and he would also worry......

"The equipment and systems are in order, and a second phase of ground taxiing test is requested." A moment later, the voice of the test aircraft group sounded again.

"Agreed, allow the second stage of the ground glide test!" Old Man Ma's voice was calm and powerful, but Lin Hongfei noticed that during the Chinese New Year, the weather was cold, and the old man's palms were full of sweat.

"It was agreed to carry out the second stage of the ground glide test and increase the throttle valve...... Release the brakes ......"

Different from the low-speed ground taxiing test, as the whistling sound of the turbofan engine became more and more sharp, and the moment the test pilot released the brake, the North County 100 "bounced" out of the car at a faster speed of the race car, and was accelerated to a speed of more than 100 kilometers per hour in a few seconds, which is far faster than those so-called "drag racers" imagined.

In less than 20 seconds, the plane had already "flitted" out of the city for more than 1,000 meters, and then it began to slow down.

Seeing that the plane did not have any bad reaction, Lin Hongfei breathed a sigh of relief and squeezed his fist hard: It was successful! God forbid!

At the same time, the report of the test aircraft team also sounded, "Report to the test center, the medium-speed ground taxiing of the aircraft feels very good, the operation is very smooth, there is no jerky feeling at all, and there is no adverse reaction on the aerodynamic surface of the aircraft, which is perfect!" ”

In the sound amplifier of the hand microphone, the test pilot did not hesitate to praise the North County 100, and even used the adjective "perfect".

"All the data is normal, all within the normal range values," at the same time, the voice of the test seat also rang out, "As far as the situation goes, this test of the North County 100 jet was very successful!" ”

"It worked!"

"We made it!"

With these two voices deliberately released through the loudspeaker arranged on the spot, the scene suddenly boiled, hats and gloves were thrown all over the sky, and countless people cried with joy: more than two years of hard work, regardless of the cost of investment, at this moment, finally reflected its value.

"Mr. Lin, we ...... It worked! We've finally made it! We Chinese will finally have our own jet large and medium-sized civil aircraft! In just this moment, Old Man Ma's eyes were already red, and the whole person seemed to be drunk, but his eyes were bright and scary, holding Lin Hongfei's hand tightly, trembling with excitement.

As the chief designer of the Yun 10 of that year, Mr. Ma knew very well that in terms of actual operation space, the significance of the North County 100 to the Republic was greater than that of the Yun 10 of that year! Naturally, he was even more excited.

"yes, we succeeded, we finally succeeded!" Lin Hongfei also couldn't help but be excited, and tears flowed down his cheeks unscrupulously, but Boss Lin didn't mean to be shy at all, so he let the tears flow wantonly on his face, "Old man, let's ...... It's not easy! ”

"Yes! Not easy! It's not easy to ......" The sentence "not easy" made the old man's already red eyes redder and redder, and his hands trembled more and more: only he knew how difficult it was for the republic's aviation industry to come to this day!

After taking two deep breaths, Old Man Ma said to Lin Hongfei, "Mr. Lin, don't you say a word to everyone?" ”

"Well, then I'll say a few words," Lin Hongfei didn't refuse, took the hand microphone handed over by the old man, and yelled at the hand with all his strength, "Comrades, everyone has worked hard, this is the best New Year's gift you gave me and the company!" I announced that I will start packing up my things now, and after a holiday, the company will prepare a plane to send everyone back for the New Year! Red envelopes and New Year's gifts are on the plane for everyone! ”

"Hooray!"

The deafening cheers suddenly resounded in the sky: this is really the best New Year's gift! (To be continued......)
