Looking at the driverless strong fifth master, Liu Yijiu's mood is very complicated.

Now a brand new road has been opened-drones, which may be worse than the United States, but he is confident that the UAVs of the Republic will shock the U.S. once the U.S. UAVs shine.

Not to mention, only some remote control toys produced in China can be used by some rebels or government forces on the battlefield in the Middle East!

"Hovering and maintaining a height of two hundred meters..." Wu Ye had already gone into the sky and flew away, leaving only a slap-sized figure. Zhao Xi's command interrupted Liu Yijiu's thoughts. The development status of the UAV is far from being able to enter the battlefield and be able to remotely control combat or attack the ground.

Originally, Wu Ye, who was flying straight in the sky, gradually turned slowly under the remote control of the technicians. The speed was not fast, but the turning radius was very large.

"How much delay?"

"Report, the order was delayed by 2.33 seconds..."

Zhao Xi frowned upon hearing this answer.

For this operation, the relative distance is not too far.However, there is a very obvious delay from when the command is issued to when the fighter plane makes a maneuver under the control of the radio signal. This delay can be seen on the ground with the naked eye.

The operator issued instructions, and the fighter still flew forward for more than two seconds before starting to turn.

"Circle around the station first." Zhao Xi didn't know what caused it. At this moment, there was no way to check and test the transponder and remote control device inside the fighter, so he could only continue to test.

Liu Yijiu was on the side, holding the Type 79 military binoculars developed by Factory 298 after the cooperation with the Ninth Academy and watching the movements of the aircraft in the sky, the flight was not very smooth.

It seems that the current remote control technology is not advanced enough, even less than the civilian remote control toys thirty years later.

"How long can the fuel on the plane stay in the air?" In order to ensure safety and avoid greater impact, the modified strong five did not carry too much fuel.

Of course, carrying less fuel is also to make the fighter lighter and easier to operate.

The maximum take-off weight of the strong five is only about 11500 kg, and the normal take-off weight is about 9100 kg. After removing the fuel, there is also a weight close to five tons. In order to monitor some data of the strong five, the above avionics system is not removed, but installed. With the addition of transponders and other things, the weight of the unmanned strong five in the sky is about 7 tons.

This is much better than the full-loaded strong five performance.

The operation is also more flexible.

In the current situation, the operation delay of the strong five is more than two seconds. Once more fuel is loaded, the delay time will be slower!

If it is used for remote control operation, it will not be able to achieve such a good effect when encountering missiles to evade...

"It can fly for 13 minutes..." The technician has been staring at the various data on the computer monitor, and when he heard the chief engineer ask this, he immediately answered.

Zhao Xi thought about it for two seconds, and immediately gave the order to land, "Prepare to dive, keep at 200 meters high, prepare to land..."

"Head, there are other prescribed actions that have not been completed..." The operator reminded Zhao Xi that according to the initial plan, during the test take-off and landing, there would be basic maneuvers such as climb, turn, dive and climb again. Which does not include circling.

Has deviated from the training plan.

"The delay time is too long, and the problem must be solved, otherwise there will be problems when performing other maneuvers." Zhao Xi also wants to succeed at one time. The problem is that the current problems encountered are much more than they expected. As expected, for a distance of more than ten kilometers, the delay should be only 0.5 seconds!

Liu Yijiu didn't speak, but kept listening to Zhao Xi and others' communication with his ears erected, while the telescope in his hand was held up, facing the strong five in the sky, observing the situation.

Radio remote control, signal transmission is not so slow, delay should be a problem of the control system.

Liu Yijiu is not very familiar with the control of non-computer chips. He can only think about how to solve these signal delay problems under the existing technical conditions.The only way I can think of is to find Huang Qingyu and others. He really doesn't have much research on this, and he is not even as good as the young front-line workers in the factories of this era in the control of radio remote control technology!

After all, the amateur life in this era is not rich. The young people in the factory rarely date after get off work, and there is no rich nightlife such as bars. Many of them are devoted to playing radio.

As Zhao Xi’s order was executed, Liu Yijiu saw Qiangwu in a circle and gradually changed his attitude. The flight trajectory that was perpendicular to the terminal building quickly became parallel. When he adjusted his attitude After a long time, the nose of the fighter jet went down suddenly when it flew over the terminal.

"Pull up!" Seeing this situation, Zhao Xi calmly gave orders.

The delay this time exceeded at least four seconds!

After a while, the unmanned strong five fighter in the sky landed on the runway of the airport staggeringly under the operation of the technicians, and finally rushed toward the grass next to the airport.

Fortunately, there was no more fuel on the fighter planes, and eventually there was no problem.

When the fighter plane was pushed into the workshop, it was already ten o'clock in the morning. Liu Yijiu had been watching from the side and did not ask.

For him, understanding the situation is the most important thing. The technology he doesn't understand must not be blindly commanded so as not to interfere with the performance of knowledgeable technicians.

After studying for a whole day, a group of people dealt with a few mouthfuls of steamed buns in the workshop from six in the morning to six o'clock in the morning, and drank cold white to solve the problem. They did not have time to eat dinner, related techniques. The staff sat in the technical room for a meeting to discuss the current problems.

"The difficulty this time is beyond our imagination. It is mainly due to the control power of the control system. The signal transmission and speed are known to everyone, but the delay in the ignition start alone has already exceeded too much. In the basic tactical maneuvers, the delay exceeded our expectations by many times. When the two tactical maneuvers of direct flight and dive were continuous, the delay reached 4.13 seconds..." Zhao Xi informed everyone of the summarized problems. Again.

"Everyone understands how the problem arises. This is very different from the Changkong-1 that we did before. The weight of Changkong-1 is only 2.2 tons, which is only about one-third of the current strong five..." Zhao Xi Everyone understands that.

Their control technology is not good enough!

The signal is transmitted to the transponder to receive and react, and then the signal is translated into action instructions and transmitted to the sensors of each system of the aircraft. The sensors then transmit the instructions to a single control system. This transmission process uses too much time.

There was silence in the technical room.

This design was improved by the remote control system of Changkong-1 after they worked on it for two months.

However, because the weight of the drone is too heavy, the control is weak and the operation cannot keep up.

"If you are flying at high altitudes and high speeds, flying at maximum speeds above 10,000 meters, and making maneuvers, you can imagine that when various maneuver commands are executed quickly under this control system, the fighter will be in the first position. Perform the second or even third maneuver before completing the maneuver..."

"This should be a structural design issue of the control system. According to your current model, don't integrate, use single channels for all?" Liu Yijiu saw no one talking and put forward his own idea.

He remembers that each basic movement of Changkong-1 has a separate channel, these channels are also cross-linked, and 85 seconds after takeoff, it begins to transfer to the on-board program mechanism to control the flight, and then the ground station uses radar information and other means. Send appropriate radio commands for remote control.

Although the ground can be controlled, it is mainly controlled automatically by the autopilot on the drone.

Of course, when shooting targets, there are no maneuvers to evade missiles.

This makes the current system more complicated than the original system by many times.

"All independent? This will make the operation more difficult!" Zhao Xi is not indifferent to Liu Yijiu's proposal. "We have considered this issue before because the operating system is too complicated..."

"What about automatic flight? Program the control chip inside so that the various maneuvers of the fighter are directly controlled by the chip module, first automatically, and after the automatic control has achieved the effect, then manual remote control..." Liu Yijiu knew Zhao Xi and the others What are the issues to consider, "For such a drone, we have to consider not only the cost, but also the effect. Even if the cost is increased, the performance will be improved. There is no problem. Such a drone is not even as good as the sky. One, the missile that is about to hit the target, will have a speed exceeding Mach 3..."

"But our research on computer programming and computer control is not too strong."

"The mobilization of people from the Ninth Academy must solve the problem here. The target aircraft is the key. Moreover, the problem we will face in the future is not only to control the target aircraft to make various maneuvers, but also to transform the J5 and J5. Six to carry out the repeated use..." Liu Yijiu said seriously, "This is a long-term project. It cannot be done just to complete the task at hand without considering other things. According to the requirements of the original domestic drone, there is no one. The aircraft meets the requirements, because the target does not require much maneuvering..."
