At around 16:00 in the afternoon, Fang Hong arrived at the headquarters of Bionic Power Company.
At this moment, at one of the company's testing sites, Fang Hong was with Ma Gaoyuan, the founder of Bionic Power Company, and a technical team recruited from NPU graduates.
"This is the bionic flapping-wing aircraft 'Hyabusa 1' that we have finalized, and it has passed the military acceptance standards, and procurement has been put on the agenda." The head of the team that designed the product introduced to Fang Hong.
"So fast? Has it been finalized and passed the inspection?" Fang Hong was quite surprised. He immediately took the Hayabusa 1 from the opponent's hand and looked at it. The head of the technical team continued to introduce to him: "Halabusa 1"
Bird 1 has a wingspan of 76.5 centimeters and a take-off weight of 285 grams, which is just over half a pound. It uses a large number of new polymer materials, so it is so light."
Fang Hong couldn't help but nodded, and after weighing the weight, it was indeed very light. The technical person in charge continued: "...but it can fly for more than 5 hours on the built-in battery, which refreshes our previous 'Homing Pigeon' model.
The world record was set at 3 hours and 42 minutes."
Hearing this, Fang Hong was surprised: "Can it fly for 5 hours?"
The technical person in charge nodded: "To be precise, it is 5 hours, 19 minutes and 37 seconds. The biggest breakthrough in setting this record is the technological progress in gliding, which saves a lot of energy."
After hearing this, Fang Hong suddenly realized that it was no wonder that it had passed the military's acceptance standards. It could last for more than 5 hours in the air and fully meet the practical conditions.
Fang Hong looked at Ma Gaoyuan and said with a smile: "As expected of a team that graduated from NPU."
Immediately, I looked at the "Hyabusa 1" flapping-wing aircraft in my hand again. It is no exaggeration to say that this is the most bird-like man-made aircraft.
At the same time, the technical person in charge next to him further introduced to him: "It can independently control one wing to perform steering maneuvers. It can not only fold the wings through the front rocker arm, but also fold the wings through the rear servo, thus
The dual wings can be folded on one side when shooting down, giving it directional maneuverability like a bird."
“Not only do many parts adopt a bionic design based on bird joints, but they are also equipped with multiple position sensors, which allow the wings to shoot down for longer than they rise up, achieving long-distance gliding capabilities, thus greatly improving flight efficiency and extending the flight time.
Overall battery life.”
Fang Hong immediately asked: "Can I fly one and have a look?"
The technical director nodded: "No problem."
At this moment, another member of the technical team put on a head-mounted display device. Fang Hong was surprised when he saw it: "Can you use MIX to control the flight? You guys are pretty fast..."
Ma Gaoyuan, who was standing aside, smiled and said: "The MIX headset can greatly enhance the perception level, and it also saves us from developing the hardware ourselves. We can write a program and use it directly."
Fang Hong nodded with satisfaction: "It's very good. The military went to Xingyu Technology a few days ago. If there is no problem with the MIX military version, 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 two need to integrate the platforms into a systematic system. Later, you can adapt the military version of MIX equipment."
The people present are all core personnel, and they themselves are involved in many confidential events. There is no need to keep anything from them. Even if they don’t tell them, they will know it soon. Moreover, the MIX military version is not a top-secret matter.
Even if we are aiming for regular deployment, we cannot keep the secret at all.
It won't be long before the military version will be announced to let the outside world know about this, 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. After a while, the "Falcon" was seen inciting the bionic wings and quickly took off.
Fang Hong's eyes followed the ornithopter. He raised his head and put his hands on his forehead to look at the ornithopter circling in the sky. He couldn't help but said: "It's only a few dozen meters away, and you can't see it with the naked eye."
It is a machine that flies just like a bird and is as quiet and silky as a bird. It can perform reconnaissance missions silently. It is really a perfect fusion of technology and nature..."
The technical person in charge on the side smiled and said: "The most intuitive advantage of the bionic ornithopter is that its bionic shape brings strong concealment and is not easy to be discovered. Whether it is applied to the military level, whether it is with the naked eye or optical equipment, this thing looks like
Just like a bird, you can't tell the difference at all."
"And camouflage is only one of the advantages of the ornithopter. It also has many other benefits, such as high flight efficiency, flexible maneuverability, and low noise. The flight efficiency of birds is extremely high, and it is far more efficient than humans based on the same weight.
With conventional aircraft, a goose can fly thousands of kilometers once it takes off, while a drone of the same weight can only fly a few hundred kilometers before running out of power."
The reason why the "Hyabusa 1" hovering in the sky at the moment can support a flight duration of more than 5 hours at a weight of less than half a kilogram is due to its gliding ability. You must know that some birds in nature can use the power of the wind to fly for a long time.
Maintaining a gliding posture greatly saves physical exertion, as is the case with this bionic bird-like ornithopter.
Fang Hong looked at the ornithopter flapping its wings and flying again and said: "It seems that it is not easy to do it to this extent."
The technical person in charge next to him immediately said: "It is indeed not easy. There are many technical difficulties in imitating the flapping flight of birds. It is simply an engineering nightmare. The first is the principle of aerodynamics. Birds seem to simply flap their wings.
But in fact, the bird's dozens of muscles and feathers work in complex ways. They not only need to achieve an upward lift, but also need a driving force to push it forward. They also need to maintain a balanced and stable posture. When the wind is blowing, they need to properly use the wind to glide.
."
"Rapid flapping forms a large amount of local unstable airflow, which is unsteady aerodynamics. In addition, the high-frequency flapping of the wing makes the material prone to fatigue damage. This is a material problem. Controlling the flight action requires fine control of each turning degree of the wing. This is
When broken down into control and algorithm issues, this ornithopter spawned dozens of disciplines."
Fang Hong nodded and asked by the way: "Compared with the West in this field, how big is the gap?"
As soon as these words came out, the technical leader and Ma Gaoyuan looked at each other for a while, and suddenly smiled at each other, and then Ma Gaoyuan answered his question: "In the field of bionic ornithopters, now, it cannot be said that there is a gap between us and the West.
, but the gap between the West and us, our current research is 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 an ornithopter. They have basically given up research and development at the national level. The endurance time of an ornithopter has always been only a few minutes or ten minutes.
But over the past two decades, due to our accumulated accumulation in the aerospace field, the emergence of talents, and the abundant R&D funds we have obtained, these new concepts have been gradually developed."
"Let's just talk about our company. Many of the technical backbones came from NPU, and with the strong financial support from the parent company, we are also making progress in many aspects. We are not only developing ornithopters, but also rotary wings.
aircraft, folding-wing aircraft, retractable wings and other new concept designs.”
Ma Gaoyuan paused for a moment and added: "Actually, many of these concepts have been developed by NASA in North America, but they will not give you the data, so we have to do it ourselves and try it again to know what is good and what is not. In the end
It is 'Hyabusa 1' that stands out, and other conceptual designs are also based on technical reserves and experience accumulation, which is not to say that they are meaningless."
