"Guo Gong really has good eyesight," Lin Hongfei smiled and nodded, since he would let Guo Ruiyu see all these power delta wings, he naturally didn't hide his meaning, "This is the ...... our company has just completed."

Without waiting for Lin Hongfei to finish his introduction, Guo Ruiyu, whose eyes were shining, couldn't wait to ask Lin Hongfei eagerly, "Mr. Lin, has this plane been test-flown yet?" ”

Excited, Guo Ruiyu has already called this power delta wing an airplane...... There is nothing wrong with calling it an airplane, anyway, until now, Guo Ruiyu has not heard of any country that has developed a power delta wing that uses a closed cockpit, let alone a country that has a power delta wing that can reach a payload of more than 1000 kg.

This 1000 kg payload, no one told him, but as a deputy chief designer of the rotorcraft, you can roughly understand some of the situation at a glance, according to the size of the power delta wing cockpit and the size of the propeller, it is easy to judge the performance of this power delta wing. Moreover, it is not so much a power delta wing as a power delta wing, or a more accurate name should be called a powered glider, but in terms of structural principles, the principle of this thing is not much different from the principle of fixed-wing aircraft, and it is naturally easier for Guo Ruiyu.

"It's already been a test flight," Lin Hongfei said, "and the performance is not bad." ”

"Can I try it?" Hearing Lin Hongfei say this, Guo Ruiyu's eyes became brighter and brighter, and he asked Lin Hongfei cautiously.

This request was really a bit unexpected by Lin Hongfei, he didn't expect Guo Ruiyu. Or Bingfei's interest in this and power delta wing of his own is so great, but it doesn't matter, the more interested they are in this thing. The greater the benefit for yourself. Immediately smiled and nodded, "Of course it's no problem." ”

Guo Ruiyu was suddenly overjoyed, rubbed his hands and said excitedly, "Great, great." ”

…………………………………………

Guo Ruiyu was very excited about Lin Hongfei's reasonableness, and he looked at the four power delta wings. One of the smallest, that is, an open fixed delta wing that can only take two people, was chosen for the test flight...... just pulled Lin Hongfei together.

He saw the five-cylinder star-shaped engine on the power delta wing, but when he saw the crew pulling an iron oil drum with a small car to refuel the power delta wing. couldn't help but be stunned, rubbed his eyes in disbelief, and asked Lin Hongfei tentatively, "Mr. Lin." This is filled with regular 97 gasoline. Not a dedicated high-grade jet gasoline? ”

"No," Lin Hongfei shook his head very frankly, "I considered this problem at the beginning of the design, high-grade gasoline is good, but it is not easy to buy, now you can buy 97 gasoline in a slightly larger place, or use ordinary gasoline......"

"However, the performance of ordinary civilian gasoline is not as good as that of high-grade aviation gasoline." Guo Gong seemed to be unable to see Lin Hongfei's improvisation idea, and thought about it. Dissatisfied interrupted Lin Hongfei's words and said.

"I'm not going to sell this thing to the army." Lin Hongfei smiled, "Since it is a civilian category, finding a way to reduce the cost of use for customers is the most important thing for us businessmen...... There are not a few people who play this thing that are particularly rich, and the consumption of gasoline is one of the major items. ”

Hearing Lin Hongfei's words, Guo Ruiyu had nothing to say, too, people's positioning is not the same level as Bingfei's Zhijiu, Zhijiu was originally for the army, naturally how good the performance is, how reliable how to come, but since the power delta wing designed by Lin Hongfei is for ordinary people to play, it is naturally how low the cost of use is, as for the speed of this thing is 120 kilometers per hour or 140 kilometers per hour, is there a big difference, and it is not used for competition.

But at this time, Guo Ruiyu didn't have time to reflect, he put on the helmet with a call function handed over by the staff next to him and modified from an ordinary motorcycle helmet, put on thick cowhide gloves, and immediately couldn't wait to jump up, and didn't forget to pull Lin Hongfei up together, and then he was a little surprised, "Hey, Mr. Lin, there is no difference between the operation of this thing and the operation of a small fixed-wing aircraft?" Why do you need this solution, you will probably add at least 20 kilograms of weight in this way? ”

The ordinary power delta wing adjusts the pitch angle of the wing surface through a crossbar that hangs down directly from the delta wing in front of it, and then controls the flight attitude of the power delta wing, but the power delta wing designed by Lin Hongfei is a little special, there is no crossbar in front, but the same elevator design as the ordinary ultra-light fixed-wing aircraft.

"Well, I prefer this design," Lin Hongfei took his helmet and gloves and responded, "My arms are always raised, I'm afraid of arthritis." ”

Lin Hongfei's reason is really fierce, Guo Ruiyu immediately didn't know what to say, but there is no doubt that this design makes his test flight more certain, whether he can control the crossbar of the delta wing is really a little weak, but the elevator...... It is also not that Bingfei has not produced fixed-wing aircraft.

The light fuselage and huge wing area bring a very short take-off and running distance and the required extremely low take-off speed, which needs to reach a speed of 40 kilometers per hour, the power delta wing lifted the wheel lightly, and glanced at the speedometer on the simple dashboard in front of him, Guo Ruiyu was suddenly surprised: 40 kilometers per hour speed can make this guy fly? How is this possible?

But the impossible is still to come, the plane hovers lightly in the air, up and down, and easily makes various flight attitudes...... Aside from the fact that the speed is not high, and after feeling the throttle state, according to the instinct of an aircraft designer, this guy can only fly at 120 kilometers per hour at the fastest, this thing is simply perfect.

Jumping down from the power delta wing, Guo Ruiyu couldn't wait to say to Lin Hongfei, "Mr. Lin, let's cooperate?" ”

"Huh?" Lin Hongfei was taken aback, he was not surprised that Bingfei wanted to cooperate with him, since the other party had sent a deputy chief engineer to talk to him, it must be because they had a strong willingness to cooperate with Guqi Industrial Manufacturing Co., Ltd., he was surprised that this Guo Gong couldn't be a little more subtle?

"What? Mr. Lin is unwilling? Lin Hongfei's reaction was misunderstood by Guo Ruiyu as that he was unhappy, and he immediately became anxious...... Are all people who are engaged in scientific research such impatient? Lin Hongfei was a little puzzled.

"It's not that I don't want to, but it's a little weird." Lin Hongfei stomped his cold feet, the open power delta wing is not good at all, sitting on it in winter, it is cold to death, even if he changes into a specially prepared leather jacket and leather pants and big scalp boots, he is also so cold that his whole body is cold, and a pair of feet seem to be his own.

"What's weird?" Guo Ruiyu stomped his feet with Lin Hongfei, and didn't forget to ask Lin Hongfei quickly.

"Who are you going to sell this thing to?" Lin Hongfei stomped his feet and asked, "You must have a target customer base for this thing, right?" I don't even know who you're going to sell to, so how can you talk about this business? ”

Hearing that Lin Hongfei was worried about this problem, Guo Ruiyu's heart immediately put back more than half of it, and said to Lin Hongfei with a smile, "Blame me for this, we plan to sell this thing to the troops." ”

Sold to the troops...... This idea is really strong, Lin Hongfei had this idea when he first engaged in this thing, but so far, he just sold more than a dozen companies for training in the 126th Division by taking advantage of his old man's special status in the 126th Division, and he never sold a single one, Lin Hongfei did not disdain, the relationship between Bingfei and the army is far closer than that between Guqi Provincial Industrial Manufacturing Co., Ltd. and the army, if they have a way to sell this thing to the army, it is not impossible, But Lin Hongfei really wants to understand, what does the army want this thing for?

"Don't you have a closed cockpit, I see, it can seat seven or eight people, and when the time comes, there will be fewer improvements, as long as you add a set of devices that use engine exhaust to keep the cockpit warm, you can ensure that even in winter, the cockpit will not be cold, although it does not fly fast, but there is a kind of army that just needs this speed...... By the way, how much does it cost to produce that has an enclosed cockpit? Guo Ruiyu, who was talking with great interest, finally had a little bit of a businessman's mind, and hurriedly asked Lin Hongfei.

"Less than 300,000, mainly because the cost of the engine and aviation aluminum tube is relatively high, if it can be mass-produced, it should be able to drop to about 200,000......" Lin Hongfei was very dissatisfied with Guo Ruiyu's cold style of changing the topic, and urged again and again, "Guo Gong, you haven't said it yet, which unit do you plan to sell this thing to?" ”

According to Lin Hongfei's current thoughts, he planned to export this thing, but now it seems that Guo Ruiyu and Bingfei don't think so?

"Of course it's the frontier garrison," Guo Ruiyu looked as a matter of course, well, if you refine it, there is still a trace of incomprehension of Lin Hongfei's thoughts, "Now those in the central and western regions will be the garrison troops to carry out daily patrols is very hard, the rugged terrain can not use any means of transportation, can only rely on walking, not to mention low efficiency, as long as you master the rules of the patrol troops' activities, it is easy to be avoided by them, but if this thing is equipped with the border troops for daily patrols, it is very suitable, the speed is not fast, It is not easy to miss suspicious places on the ground, flying in the air is not limited by the terrain, and if there is a situation, you can support it at any time, and most importantly, the cost of this thing is too cheap, much cheaper than equipping a helicopter...... By the way, Mr. Lin, how high is the maximum ceiling of your thing? At what altitude will it be able to take off normally? (To be continued.) )
