Coquettish Rebirth

The 602 aircraft and the cpc device are combined together.It is actually not difficult to combine the two machines. After everyone agrees on the hole spacing of the screw connection and the specifications of the screws, they are transported and everyone uses screws to connect the two machines together.However, the American experts are hypocritical, not because of their various decorations, but because this kind of buffer equipment is relatively delicate, and the equipment designed by their cpc also pays attention to various things that are in a straight line with the center of gravity. A shock and a little crooked, resulting in the camera crooked in mid-air, isn't this a waste of film?This film also costs money to buy! <There was a problem with the equipment over there, and it was a waste of a roll of 400 feet of film. Anyway, more film cameras couldn’t fit, so the loss was a few thousand dollars at most.However, if something goes wrong with the 602 plane, for example, if it falls from the sky, it may break the professional camera worth more than 200 million yuan!That's right, this test is all taken as real, and it really needs to be on top-level cameras!

After the two parties checked their own equipment individually, they cooperated to connect the equipment together, and then they checked again, and then installed the home camera and counterweight first—after all, this is a combination In the first test of the complete set of equipment in the future, always be careful.In case something goes wrong and falls, it's just a family camera.Let’s experiment with a home camera first, and if everything is ok, it’s not too late to switch to a professional camera!

Soon, the principle flight test using a home camera as a substitute was successful, and then the real camera was installed, and the film was shot to see how it looked in the air.In the preparations before take-off, Nolan and Wally carefully inspected one side of the camera, which is called a cautious one—although Nolan doesn’t like digital technology very much, but for this new technology and new equipment that is actually shot on film. Still quite like it.And this thing is still an improved model of the Steadicam invented in the 70s, and it is not completely new. A fundamentalist like him can still accept it.

"Start!" After the old man from China's 602 Institute yelled.This nearly complete flight test will begin.There was only a humming sound, and the drone slowly rose on the two-meter-high separate landing gear. When it first started to rise, it really didn't shake at all.It was as if a particularly stable hand lifted such a flying shooting platform to the sky!This is actually very easy to understand.Because the output of the propeller depends on the motor.The output of the motor is supplied by electricity, and it is supplied uniformly, so the speed of the motors of the eighteen propellers is exactly the same at this time.There is no such thing as which propeller exerts more power and which has less power. Therefore, if there is no lateral airflow interference during the ascent of the plane, it will naturally fly very smoothly!

Then when the plane flew to a height of about six floors, I suddenly saw a slight shaking of the plane visible to the naked eye!However, it seems that the plane is self-correcting its flight attitude during this shaking - the propeller and the motor below seem to be adjusting the angle slightly, so that the plane can be as stable as possible in the position just now!Seeing this, Jia Hongjian really sighed in his heart that the 602 is awesome. How long has it been? After the prototype technology experiment, the flight attitude control system was developed almost immediately, which is too efficient. !Naturally, the flight control system researched by others may not be perfect, but it is amazing to be able to build a shelf as a whole and make basic functions, okay? After all, how short the time is!Even Jia Hongjian thought that the design work of 602 might be carried out in batches at the same time - when designing the aircraft here, another team directly started to study the flight control system!That's why the progress is so fast!

After the plane flew to the height of the six-story building, it did not descend immediately. There will be various other experiments in the future, such as accepting various crosswind disturbances on the six-story building, which exceeds the height of the 602 design building. remote control flight.This flight was operated by the old men with a remote control similar to a remote control aircraft at the request of Wall-E.The photographer Wally imagined a shooting scene, and then asked the old man to control the plane to fly a prototype, keeping the camera lens as close as possible to a certain virtual center, which is actually imitating the 360-degree shooting method around the characters of.

However, it may be because the remote control is completely modified with the remote control of the model aircraft, so the function of the remote control is not enough, and the flight can be kept as stable as possible in a straight and horizontal flight. It's a bit out of circle, after all, the inclination angle of the motor is controlled by pushing the joystick on the remote control with the old man's finger.So even if the old man tried his best, the plane flew in an approximate circle in the end!

At this point, even if Jia Hongjian and the others didn't say anything, the old man who was controlling him started talking, "No, as expected, the real knowledge comes from practice. I think this flight control system needs to be changed, and the following settings should be added in the future. After the radius of the circle is increased, the programmed motor automatically deflects to automatically fly around the circle..." Hiss!Seeing how powerful the old man is, the first thing that comes to mind is computer control!Even though Jia Hongjian doesn't know much about the knowledge involved, he can still know that it is necessary to increase the operating platform on the ground, such as getting a notebook to control, and after designing the flight radius in it, he can use the machine inside the plane to control it. Load the computer for analysis and calculation, and then figure out how to change the inclination angle of the motor every degree of flight around the circle, so that you can fly a perfect circle!

Of course, Wally also put forward a suggestion - can you get something like a dc digital camera at the position of the camera's viewfinder, and then see if there is any way to see the viewfinder? What is achieved is that the scene captured by the lens can be transmitted to the ground. Only in this way can the photographer know what he has photographed on the ground!Otherwise, I don’t know how the effect will look after each shooting. If I really want to know, I have to send the film to be developed before I can see it—in this era, there are no professional digital cameras for filming!

The old men nodded in agreement with adding a digital camera or video camera behind the viewfinder, but they also stated a problem-they are not good at how to transmit, after all, this kind of For the transmission during shooting, it can’t be said to use wired transmission?But in terms of wireless transmission, 602 and the others really haven't studied this.Even if it is the transmission of various information chains to be studied on the armed helicopter, this kind of equipment is also researched by a specialized military industry within the system!What they studied in 602 was an aircraft itself!It’s like saying that fighter jets are researched by Chengfei, but what Chengfei researches is the aircraft itself, and the fire control system of fighter jets is also made by Changhong and the others, and the military industry institute with Changhong is in charge. Those who study fire control radar!

At this moment, why did Jia Hongjian suddenly feel as if he knew how to solve this matter? "I'll take care of this." After he said this, all the Chinese people in the audience turned their heads to look at him, and then Nolan, Wally and a group of Americans from CPC still couldn't figure out what was going on. So Jia Hongjian said it again in English.After he finished speaking, Nolan and his group of foreigners were all dumbfounded—fuck, Mr. Jia still has this ability?Not to mention foreigners, even the capable old men of 602 looked at Jia Hongjian in amazement.

At this time, I heard Jia Hongjian explain with a smile: "I have a company called ams in the United States. This company has developed a wireless transmission standard called wifi. It uses the internationally accepted 2.4ghz transmission frequency. Theoretically, the bandwidth of the up and down transmission can reach 1ms, and it can basically transmit a passable picture back, but it must be clear without the camera. If it is clear, the bandwidth is estimated to be 4m or even 10m. , but I can ask them to study it first to see if they can research it..."

Whoa!After what Jia Hongjian said at the time, foreigners were a little stunned—they hadn’t heard of ams company and this technology, but they had heard of ams company, didn’t it mean that the sales seemed to be particularly high-end? Is it the company of your computer?It is said that it was decided that the boss re-started the company?Does Jia Hongjian still have shares in it?Of course, Jia Hongjian didn't need to explain in detail. This was his private matter, and the person in front of him was not the police uncle checking the household registration. Why did he talk about everything?And the matter of wireless transmission, originally he planned to use it on a similar tablet computer, but later due to various technical reasons, it was only used on a wireless mouse and keyboard. It seems that there is not much difference between the wireless transmission wifi and other wireless transmission protocols, even if the distance is a little farther, they may not understand the ambition behind such a standard!

In any case, such a principle test is basically successful. Although the stability of the lens shooting will not be known until the film is developed, at least this time it was found that the flight problem of the aircraft is not too big, at least it was found A few points that can continue to be adjusted!According to this kind of expectation, Jia Hongjian expects that in another three to four months, this can be made into a practical product no matter what! (To be continued..)
