Coquettish Rebirth

China's current civilian helicopter market has really not improved at all.In later generations, at least some police forces in big cities still have helicopters. Although there are not many, there may be only one or two in a city, but at least there are still.But in this era, few rich people think about buying helicopters, and they can’t use them if they buy them, because China also controls the low airspace, so if you want to fly a helicopter, even if it’s not very high , That also needs to be reported, and it is impossible to leave just after getting on the plane.Under such circumstances, the Jia family didn't even buy a helicopter, so how could other families buy it?Therefore, it is certain that 602 and Changfei lived a normal life.

Changfei is actually a little bit better, because they can also make cars to subsidize their households. As for the 602 Institute, they are military industrial research institutes, so it is impossible to make things by themselves?So in the 602 Institute, there is really less money and less work.The only thing that is better than 601 and 611 is that the industrial level of Shanxi Province is almost the same, there are more blue sky and clear water, and the air environment is better.

So when the 602 learned that Mr. Jia from Huaxia Hi-Tech was coming to discuss business, and even the general manager of Baoli Company was personally accompanying him, the standard of reception was quite high!How high is it specifically?It can be said that apart from a few people from the civil aircraft department, all the research experts from the military aircraft department were dispatched to accompany the detailed discussion. Even a blond, blue-eyed, Russian-speaking old man attended such a meeting accompanied by an interpreter. A reception!

At the reception, when Jia Hongjian showed some performance data they needed—for example, the airborne time should be greater than 10 minutes, and the effective mission load should be at least 30 kilograms.It is best after about 35 kg and so on.After this group of experts thought for a while, the series of questions they asked directly showed their professionalism—for example, what is the maximum flight speed required after carrying a load into the sky?Is it ten meters per second or how much?Then there's the issue of handling—is there some crosswind or something, does the drone need to be self-stabilizing?That is, do the propellers of the aircraft need to adjust their own deviation angles to keep the aircraft as stable as possible?

And then, when the aircraft is being controlled, does it need a wireless device to shoot and control the video? This is not about the stuff captured by the camera, but when the aircraft itself is controlled, does it need a small camera to take pictures? environment?Even when shooting with such a camera, do you need to have a small DC digital camera next to the viewfinder of the camera or something like that?The video signal is transmitted wirelessly.That way the cinematographer and the director can see what the camera is getting, right?It can’t be said that after going there once, I don’t know how the pictures were taken during the flight, so I went down to shoot the film and then watched it after it was developed?

even.Such a plane is in flight when shooting.Do you need a platform with three-axis stabilization?Because the plane takes off, it is impossible to say that the journey is as smooth as shooting on the ground.Even if it's shooting on the ground.The photographers also need to use a tripod to support the camera, so that the lens can be stabilized!The pictures shot by hand-held or shoulder-mounted cameras are very shaky!

And during the flight of the aircraft, there will always be problems of one kind or another.For example, it is after the plane takes off that it is impossible to die.The actor was performing, and suddenly there was a slight breeze, which blew the plane a few centimeters away. You may not see any movement of the plane on the ground, but this may cause problems for the camera. The result will be obviously a bit "flawed"!So you can't just count on the perfect weather and no wind when shooting?

So there must be an adaptive three-axis self-balancing platform to mount the camera?This kind of self-balancing platform hanging on it should be like the head of a bird or a chicken. It can achieve three-axis self-stabilization. The body moves circularly or up and down within a small range, and the chicken neck can automatically make movements to offset the movement of the human hand, and then keep the chicken head and the camera as stable as possible at one point.Why should there be one of such a thing?

Shit, as soon as Jia Hongjian heard this, he immediately felt that there was a lot of trouble, right?At first he thought it would be easy to make such a thing, but now that he thinks about it, it is estimated that it is not difficult to make a simple multi-rotor drone that can fly, but the difficulty is that it can be equipped with a professional camera for professional filming. Such a system for shooting!Just chatting with these experts for a while, Jia Hongjian felt that the stuff inside was too troublesome. Let’s talk about the aircraft’s self-stabilization system, which is to let the aircraft automatically maintain stability when it encounters turbulence in the air. Even if there is a gyroscope to judge the three-dimensional deviation to support autonomous stability, but this kind of stuff that does not need to be controlled by humans and the aircraft will quickly correct its flight attitude, no matter what, it needs to install a single-chip microcomputer in the aircraft. What, and then you need human programming to make flight control software?Otherwise, if the gyroscope detects that the plane has deviated, how does the machine know how to adjust itself?How to adjust and how much to adjust, all of which need software to write!The quality and efficiency of software writing determine how fast the aircraft responds when it is stable and how stable the process is!

To be honest, Jia Hongjian is not the kind of boss who thinks everything is easy without knowing anything. He can guess this kind of flight control system based on his own experience. It must have been a long time to build - one or two years is probably considered short!There is even a three-axis self-stabilizing platform that is needed for stable shooting. It is probably quite troublesome to build such a thing?Also do various research?This kind of thing has been researched, nothing else to say, the research on this kind of stabilizer is successful, praise and change it, put it on the ground, how awesome is this thing?It is estimated that by then people will be able to shoot with a handheld camera similar to orbital platform photography and the crane photography used by Ang Lee and the others?So this can be said to have created a breakthrough new product, okay?

etc!Suddenly, Jia Hongjian thought of something... In his China Satellite TV, it seems that when the party is held, the cameraman always brings a very magical equipment to shoot - in some pictures and scenes, The big cameraman couldn’t use a tripod to stand in place to shoot, so he needed to walk in with the camera.At this time, they were wearing a special device to carry the machine forward or backward - a thing like a vest, and then a few rocker arms protruded from the waist, and then connected to a bracket to hold the camera.In this way, when the photographer is walking, he does not actually carry the camera on his shoulders, but supports the camera on a metal arm connected to his waist.When a person walks, the shaking of the shoulders must be large, while the shaking of the waist, which is close to the center of gravity, is small!Then, adding such a rocker arm may also have a little shock absorption effect, which can make the pictures taken by the cameraman walking very stable!

If Jia Hongjian remembers this kind of thing correctly, there are many photographers who use it on the field. It’s not used to shoot athletes running or something during the game, but after the game is over, the athletes leave the field. When returning to the locker room, or coming out of the locker room after the game, there is no time to set up a tripod for the photographer or something. In order to make the picture stable, many sports photographers wear the equipment worn by the Huaxia Hi-Tech photographer above!

Hiss... what is this device called?Other manufacturers must have various stabilizing and shock-absorbing technologies, so can we cooperate with them to help them develop a three-axis stabilized platform, and then we 602 will research aircraft?In this way, if the two sides cooperate separately, it will speed up the research from the perspective of overall planning. After all, the two sides started together. Maybe after half a year, both sides have researched the results, and then put together and debug it later, maybe it can be adjusted. Good to catch up with Nolan's filming!

At this time, after he thought of this, he made a phone call to the hotel in Nyulumuqi - Nolan and his photographer friend robot Valina are still living there waiting for visas! "Wali, let me ask you, that is, the photographers who are often used in competitions and variety shows wear a vest with a metal rod on it... and the set that is connected to the camera, what is it called? Which one of them? Produced by the factory?" <Exclusive technology, but after so many years, their most basic patents have expired, so many companies in the market are now making this Steadicam product.Moreover, Steadicam is not considered a trademark or technology, but has become a synonym for a series of camera stabilizers... What's the matter, Mr. Jia, do you want to buy a Steadicam?I know how to use that thing, I have special training, special steps and all! "Wall-E the robot said endlessly on the phone.

As soon as he heard this, to be honest, Jia Hongjian really became a little greedy for a moment—this Steadicam patent has expired, so can we use the expired patent to develop our own?If we develop it ourselves, we can still go to takeaway later, right? (To be continued..)
