Looking at the thing in front of him that could only be described as simple, Lin Hongfei's eyes were full of excitement.

"Hongfei, can this thing really fly?" Dongfang Xiaoling looked at the thing in front of her, her eyes flashed with suspicion, and she was a little worried, "I really don't think this thing can fly...... This thing doesn't look like an airplane at all. ”

The thing in front of me is, to put it simply, a small tricycle with an exposed engine in the rear, connected to a pair of two-bladed propellers...... Yes, that's right, it's a two-seater power delta wing.

Although the power delta wing is a little too cool in this weather, the enthusiasm for flying still makes Lin Hongfei's heart excited, as if there is a fire burning.

For the power delta wing, the core place is the engine, but the engine on the power delta wing is a little different, not the use of those foreign power delta wing piston aero engine, but Lin Hongfei personally in the engine that was tentatively named BJ18 on the basis of a wide range of modification of the engine, not only increased the twin turbo, but also optimized the intake and exhaust system, in the process of engine modification, The only thing that made Lin Hongfei a little distressed was that he couldn't find a decent turbocharger in China. Breuich bought it in Germany.

But now it seems that it was all worth it, and after such a modification, the engine burst out with a maximum power of 240 horsepower, and it is not too easy to push a power delta wing with a huge wing area with such power.

"This is not an airplane originally," Lin Hongfei explained to Dongfang Xiaoling with a smile, "This thing is called a power delta wing, and it hasn't been popular abroad for long, but don't look at the structure of this thing." It is known as the safest aircraft, but in terms of safety, no aircraft can be safer than it. ”

Dongfang Xiaoling shook her head suspiciously.

In the eyes of this little girl who is an accountant by profession, the more complex things should be safe, not such a simple and shabby-looking thing, well, so shabby that it doesn't even have a shell...... In this winter, wouldn't you freeze to death if you fly up?

"Just watch." I made it myself. Others don't know. Lin Hongfei knew in his heart how safe this thing was, shook his head with a smile, and waved his hand to the people around him at the same time.

Many workers who were not on duty heard that Mr. Lin was going to test fly a new plane, and they all gathered to watch the excitement, although the simple appearance of this "plane" made many workers disappointed, and they did not think that such a thing could bring any profits to the company. But seeing Lin Hongfei and Lin always waving to him, the workers still shouted excitedly.

Regardless of whether the project can make the company profitable or not, but in everyone's opinion. Such a simple thing, if it can really fly, in the future, our big guys will have the capital to brag about: do you know it? Our Buk-gun Industrial Manufacturing Company. You can even build an airplane! …… Although Lin Hongfei has said several times that this thing is called a power delta wing, not an airplane, no one takes Lin Hongfei's words as a thing, in everyone's opinion, as long as it can fly and has wings. That's airplanes.

Seeing Lin Hongfei wearing thick leather gloves and a big motorcycle helmet there, Dongfang Xiaoling became more and more worried in her heart, and finally couldn't help it, grabbed Lin Hongfei, and a trace of fear flashed in her eyes, "Or, let others try it, you ...... I'm not at ease. ”

Dongfang Xiaoling had expressed her worries several times before, but at that time, Lin Hongfei had always felt a little funny about this girl's worries, but at this moment, looking at the fear and worry in Dongfang Xiaoling's eyes, Lin Hongfei's heart suddenly trembled violently! How could Lin Hongfei not understand, if he didn't love himself very much, how could this girl show such feelings? …,

"It's okay, don't worry," Lin Hongfei patted Dongfang Xiaoling's hand gently, "That's it, I'll only fly at a low altitude first, at most a height of four or five meters, and if it's okay, then fly to a high place, okay?" ”

"That'...... If you do notice that something is wrong, you have to get down quickly. Dongfang Xiaoling also knew that she was a little unlucky to say this at this time, but the worry in her heart made Dongfang Xiaoling unable to hide her inner feelings no matter what, and she knew that she couldn't stop Lin Hongfei, so she had to comfort herself in her heart, so that she believed that nothing would happen to Lin Hongfei this time.

"Hmm!" Lin Hongfei nodded vigorously.

In the previous life, in addition to the fanatical love of engines and cars, Lin Hongfei's few remaining hobbies were gliders and power delta wings, but unlike the fanatical love of internal combustion engines, internal combustion engines and automobiles as a means of making a living and making money are inevitably affected by many factors, but in the two fields of powered gliders and power delta wings, Lin Hongfei has always entertained himself, in this field where he can give full play to his talents, Lin Hongfei has obtained a more pure spiritual enjoyment. It is also because of this extreme fanaticism that Lin Hongfei has more than 5,000 hours of flight time on these two aircraft, and it is polite to say that at this stage in China, in the field of power delta wing, no one's level and attainments can be higher than Lin Hongfei.

……………………

Those who came to visit Lin Hongfei's "test flight" were not only the workers in the factory who did not have to go to work for the time being, but also Commander Liu Fengcai and Liu of the Municipal Military Division.

The control of aircraft in China is very strict, and the take-off of any kind of aircraft must be approved by the local army, that is, Lin Hongfei can still have this face, if it is someone else, he will not even have a chance to fly.

At this moment, Commander Liu was looking up and down at Lin Hongfei's power delta wing with a curious face, and while he was amazed, he saw that Lin Hongfei was about to go up and start, and hurriedly grabbed Lin Hongfei, "Xiaolin, the low-altitude performance of this thing should be good, right?" ”

Although he has never worked in the Air Force, he still knows the basic knowledge of some aircraft, and there is absolutely no problem with such a huge wing area, but he only carries a 300-kilogram heavy power system and riding space.

"Well, let this thing fly high. He may not be able to fly yet," Lin Hongfei pointed to the engine behind him, "The piston engine is still not suitable for high-altitude flight." ”

The working principle of the piston engine greatly limits the high-altitude performance of the engine, and Commander Liu naturally knows this truth, which is why he asks why he has such a question: Well, although I don't know the simple aircraft of Lu Dao...... Wrong, not airplanes. What does the performance of this power delta look like in action. But from my own experience, this thing seems to be pretty good, and it doesn't seem to be expensive, if you can, you can buy a few from Xiaolin for use in the military region.

Commander Liu nodded, really curious. "How high can this thing fly?"

"If I'm not mistaken, the flight limit altitude should be 2,000 meters." Lin Hongfei replied quite confidently. In fact, he felt that it was a pity, if the EFI system could be introduced, the intake and exhaust system of the engine could be optimally controlled by computer. With a turbocharger, it's no problem to let this guy fly up to 5,000 meters, but now, unless it's a special high-prototype carburetor, you want to fly that high. There is no possibility at all.

Lin Hongfei was not very satisfied with this flight altitude, but Commander Liu obviously didn't think so in his heart, he grew his mouth in surprise, and it took a long time before he closed his mouth and let out a long breath, "2000 meters? ”…,

"Well, the lowest is 2000, no matter how high the altitude is, I don't have the atmospheric pressure data at that altitude," Lin Hongfei was a little helpless, "But if you can have a supporting EFI system, you can actually fly higher." ”

But Lin Hongfei's words were obviously said to the deaf, and Commander Liu was completely immersed in the horror caused to him by the information leaked by Lin Hongfei at this moment: Nima! How can such a simple thing fly as high as 2,000 meters?! …… Well, in this winter, people will turn into ice cubes when they go up, right?

"Not bad, not bad!" Commander Liu, who originally thought that this guy could only fly four or five hundred meters at most, nodded again and again, and his interest in this thing suddenly increased, and he had already begun to think in his heart, since he could fly so high, then this thing should be of great use in the army, right?

Lin Hongfei didn't hear what Commander Liu was saying clearly, Lin Hongfei, who had just put the earbuds of the walkie-talkie into his ears and put on his helmet, looked at the power delta wing in front of him, and his eyes were scorching: Sky, I, Lin Hongfei, are back again!

…………………………………………

Although he was excited, it did not mean that Lin Hongfei had any neglect of safety work, according to the habit he had developed when he used to play the power delta wing, he did all the inspection steps before takeoff, and confirmed that the entire power delta wing was in a good flyable state, Lin Hongfei nodded with satisfaction, sat on the seat, fixed himself with a five-point seat belt, and gave Dongfang Xiaoling a thumbs up on behalf of success when starting the engine to warm up.

Seeing Lin Hongfei's gesture, Dongfang Xiaoling was slightly stunned, and then returned a bright smile to Lin Hongfei, and at the same time gave Lin Hongfei a thumbs up, and said to Lin Hongfei silently in his heart, "I know that you don't want me to worry, since you don't want me to worry, then I will show my best self in front of you." ”

As if the heart has a heart, Dongfang Xiaoling's words in her heart just finished speaking to Lin Hongfei, Lin Hongfei suddenly began to step on the accelerator, the wooden double-bladed propeller suddenly began to rotate at high speed, driven by the engine with a maximum output of up to 240 horsepower, a huge thrust, trying to push the ride and power car under the delta wing forward, but the wheels that were braked by the brakes firmly prevented the more and more irritable engine.

Finally, feeling the increasingly powerful thrust from the car under him, Lin Hongfei released the brake violently, and the car rushed forward like an arrow from the string, just crossed less than 30 meters, Lin Hongfei pushed forward the control lever of the delta wing, and the huge wing was lifted upward, and the entire power delta wing suddenly left the ground and flew into the air, just like a light swallow.

"It's flying! It's really flying! At this moment, looking at Lin Hongfei who was soaring into the air, everyone below was boiling!

Although it has long been known that Mr. Lin is building an airplane, even at the moment before the plane takes off, few people believe that such a simple thing can really get out of the shackles of the ground and fly into the sky like a cheerful bird.

Dongfang Xiaoling, who fell into a huge ecstasy in an instant, was almost blank in her mind, and only one thought kept echoing: he succeeded! He really succeeded!

She didn't know what an airplane was or what a power delta wing was, but she instinctively felt that the huge star-shaped engines developed by Lin Hongfei were to prepare for the manufacture of larger aircraft, and now this plane has just flown into the sky...... Since he said that it is called a power delta wing, it is a power delta wing, and this power delta wing that has just taken to the sky is preparing for himself to make a bigger aircraft in the future. …,

Lin Hongfei abides by the agreement he made with Dongfang Xiaoling, just flying at a very low altitude, and the stable flight attitude makes the people watching below and Dongfang Xiaoling gradually relax...... Even though Lin Hongfei has said it countless times before, everyone still thinks that this is an airplane, not a power delta wing.

"Alright, I'm going to try a little higher." After flying at an altitude of about 5 meters for a few minutes, Lin Hongfei, who had basically mastered the performance of Du Yu's power delta wing, talked to the ground personnel through the walkie-talkie, and the next moment, the power delta wing was like a light bird, and immediately flew to a higher height!

…………………………………………

Rostock, the privileged representative of Volkswagen, was also invited to participate in the test flight ceremony, and when he saw the power delta wing made by Lin Hongfei himself, Rostock couldn't help but groan in pain: God!

It doesn't get any worse than that.

He knew very well that at the moment when Lin Hongfei's wheels were released from the ground, all of Volkswagen's previous plans would be overturned, and the rules for getting along with Lin Hongfei and the Beijun City Industrial Manufacturing Company needed to be re-examined......
