Saturday, June 3.

At about 16 o'clock in the afternoon, Fang Hong came to the headquarters of Bionic Power Company.

At this moment, on one of the company's test grounds, Fang Hong is with Ma Gaoyuan, the founder of Bionic Power, and a technical team recruited to graduate from Western University of Technology.

"This is the bionic flapping wing aircraft 'Hayabusa1-1' that we have finalized, and it has passed the military acceptance criteria, and the procurement has also been put on the agenda." The team leader who designed the product introduced it to Fang Hong.

"So fast? Has it been finalized and accepted?" Fang Hong was quite surprised, and immediately took Hayabusa No. 1 from the other party's hand and took a look. The person in charge of the technical team continued to introduce to him: "Hayabusa 1 has a wingspan of 76.5 centimeters and a take-off weight of 285 grams, which is just over half a catty.

Fang Hong couldn't help but nodded, and easily weighed the weight, which was indeed very light, and the technical person in charge continued, "...... But it can fly for more than five hours on the built-in battery, breaking our own world record of 3 hours and 42 minutes set by the pigeon."

Hearing this, Fang Hong was surprised: "Can you fly for 5 hours?"

The technical director nodded: "To be exact, 5 hours, 19 minutes and 37 seconds, the biggest breakthrough to be able to set this record is the technical progress at the gliding level, which saves a lot of energy."

Hearing this, Fang Hong suddenly realized, no wonder he has passed the military's acceptance standards, and the endurance of more than 5 hours in the air is already fully practical.

Fang Hong looked at Ma Gaoyuan and said with a smile: "It is worthy of the team that graduated from Xi'an University of Technology."

Immediately, he looked at the "Hayabusa No. 1" flapping wing aircraft in his hand again, and it is no exaggeration to say that this is the most bird-like man-made flying machine.

At the same time, the technical leader next to him further introduced him: "It can control a wing alone to perform steering maneuvers, not only through the front swingarm to fold the wing, but also through the rear servo, so that the two wings can be folded on one side when the next shot, giving it bird-like directional maneuverability."

"Not only is there a bionic design based on the bird's joints in many parts, but it is also equipped with multiple position sensors, which can make the wings shoot down for longer than upwards, enabling long-distance gliding ability, which greatly improves flight efficiency and extends the overall endurance time."

Fang Hong immediately asked, "Can you fly one and take a look?"

The technical lead nodded, "No problem."

At this moment, another technical team member put on a set of headsets, and Fang Hong was surprised when he saw it, "Can you use Ix to fly the controller? You're pretty fast......

Ma Gaoyuan, who was standing on the side, smiled and said, "The IX headset can be greatly enhanced at the perceptual level, and it also saves us from developing our own hardware, and we can use it directly by writing a program."

Fang Hong nodded with satisfaction: "It's good, the military went to Xingyu Technology a few days ago, and the Ix military version will not have any moths, and it will be mass-produced next year."

This time it was Ma Gaoyuan's turn to be surprised: "Is there such a thing?"

Fang Hong nodded again: "I talked to Qin Feng yesterday, you must do a good job of platform integration and linkage into a systematization, and then you can adapt the military version of Ix equipment here."

The people present are all core personnel, and they are involved in many classified incidents, and there is no need to keep anything for them about these things, even if they don't say it, they will soon find out, and the Ix military version is not a top-secret matter, and it is impossible to keep it secret at all if it is to go to the goal of standing equipment.

It won't be long before the military version will be released to let the outside world know that there is such a thing, but the details will be reserved.

But at this moment, the flapping wing aircraft in Fang Hong's hand had been handed to the pilot, and after a while, he saw this "Hayabusa" instigating the bionic wings to rise into the air soon.

Fang Hong's eyes followed the ornithopter, he raised his head and put his hand on his forehead to look at the ornithopter flying in the sky, and couldn't help but say, "It's just that at such a distance of more than ten meters, it is completely impossible to see that it is a machine flying with birds

It is as quiet and silky as a bird, and it can quietly carry out reconnaissance missions, which is really a perfect fusion of technology and nature......

The technical person in charge on the side smiled: "The most intuitive advantage of the bionic ornithopter is that its bionic shape brings strong concealment, which is not easy to find, and when applied to the military level, whether it is the naked eye or optical equipment, this thing looks like a bird that cannot be distinguished at all."

"And camouflage is only one of the advantages of the ornithopter, it has many other benefits, such as high flight efficiency, maneuverability and low noise. The flight efficiency of birds is extremely high, according to the same weight is far more than the human conventional aircraft, a wild goose can fly thousands of kilometers at a time, and the same weight of the drone can fly hundreds of kilometers at most before running out of power."

The reason why the "Hayabusa 1" hovering in the sky at the moment can support more than 5 hours of flight time with less than half a kilogram is that the gliding ability is indispensable, you must know that some birds in nature can use the wind to maintain a gliding attitude for a long time to greatly save physical consumption, this is the case with the ornithopter of bionic birds.

Fang Hong looked at the ornithopter that flapped its wings again and said, "It seems that it is not easy to be able to do this level."

The technical person in charge next to him immediately said, "It's really not easy, there are so many technical problems to imitate a bird's flapping wings, it's an engineering nightmare. First of all, the principle of aerodynamics, birds seem to simply stir their wings, but in fact, the dozens of muscles and feathers of the bird are complex, and they not only need to achieve an upward lift, but also need a power to push it forward, and to maintain a balanced and stable attitude, and to glide with the help of the wind when there is wind."

"Rapid flapping forms a large number of locally unstable airflow, which is unsteady aerodynamics, in addition to the high-frequency flapping wing, the material is easy to fatigue and damage, this is a material problem, and the control of flight action requires fine control of each turning degree of the wing, which is a control and algorithm problem, and the subdivision of this ornithopter has given birth to dozens of disciplines."

Fang Hong nodded and asked by the way, "How big is the gap between this field and the West?"

As soon as these words came out, the technical person in charge and Ma Gaoyuan looked at each other for a while, and suddenly looked at each other and smiled, and then Ma Gaoyuan answered him this question: "The field of bionic ornithopter, now, cannot be said to be the gap between us and the West, but the gap between the West and us, and our current research has been significantly ahead of the West."

Hearing this, Fang Hong smiled slightly: "Oh? Really?"

Ma Gaoyuan continued with an affirmative tone: "The West has long realized that it is too difficult to develop ornithopters, and they have basically given up research and development at the national level, and the endurance of ornithopters has always been only a few minutes or ten minutes. However, in the past 20 years, we have accumulated a lot of experience in the aerospace field in China, the emergence of talents, and the abundant R&D funding, and these new concepts have slowly come out."

"Let's talk about our company, many technical backbones have come out of Xi'an University of Technology, coupled with the strong support of the parent company at the financial level, we are also multi-point parallel, not only engaged in ornithopter, but also rotor, folding wing, telescopic wing and other new concept design."

Ma Gaoyuan paused for a moment and added: "Actually, there are many concepts in which NASA has done it in the past, but people won't give you the data, so we have to do it ourselves and try it again to know what's good and what's not.

Fang Hong nodded and commented, "It's good."
