Chapter 291 (1/2)

”For example, at this stage, research on anti-aircraft gun radar and airborne radar should be carried out.” Xierik continued to provide advice along his own ideas: ”if our anti-aircraft guns can be added with radar, they can attack enemy aircraft more accurately, and our fighters can also accurately capture targets at night with radar.”

Gorin has no objection to the opinions put forward by hilrick. It's really a good idea to put this radar into the sky!

”General Shrek, our existing radar equipment is cumbersome.” Dr. hollmann hesitated for a moment, but still expressed his concerns: ”if it is provided to antiaircraft guns or fighters, it will be very large and weigh too much. Moreover, the power consumption is quite large. I'm afraid it's inappropriate.”

In this era, almost all electronic devices are extremely bulky, the most essential of which is the electronic tube with glass bubble!

Electron tube is one of the earliest electric signal amplification devices. From the outside, it is a large glass bubble, and inside there is a filament to emit electrons, as well as a control grid, an acceleration grid and an anode. The device uses an electric field to inject an electronic modulation signal into the control grid in the vacuum, and obtains different parameter signal data after signal amplification or feedback oscillation at the anode.

The discovery of electronic tubes has cross era significance and represents the arrival of the electronic age. Until later generations, some music enthusiasts love to use courage, which is composed of electronic tubes.

Electronic tubes have opened the door to the electronic age. All electronic equipment, radios, radio stations, loudspeakers, radios, etc. in this era are made of electronic tubes.

However, this thing still has disadvantages, that is, it is too big! At the beginning, an electron tube was a large light bulb. Later, after continuous evolution, an ordinary electron tube was about as thick as a cigar and about half the length of a cigar.

Moreover, the filament needs to be heated, which takes time to work.

Hearing the complaint of the famous German electronic engineer, hilrick suddenly remembered a lot of things in his mind.

In later generations, the East and the West took different roads. Facing the huge volume of electron tubes, the Soviet Union took the road of miniaturization of electron tubes, while the West took the road of transistors and integrated circuits. Facts have proved the correctness of the Western Road, but transistors need technology.

In later generations, transistors were made in Bell Labs in 47 years. Now, there are nearly ten years left.

Therefore, both legs have to go. Find some electronic experts to study transistors. At the same time, immediately start to miniaturize electronic tubes!

Compared with the transistor of the new theory, the miniaturization of electron tube is within the knowledge of hilrick.

This is the rod vacuum tube. The previous electronic tubes came from the bulb, so the electrodes were at one end, while the Soviet Valentine changed his mind and turned the vertical glass tube into a small thin glass tube placed horizontally, reducing the volume by more than ten times!

This kind of electron tube has almost the same volume as the original transistor. Moreover, although the volume is small, the performance is not poor. This kind of electron tube with parallel thin rod grid has higher efficiency, higher frequency range, greater ”mechanical performance” and ”radiation resistance”.

Xierik explained his idea in detail, and everyone present was surprised to open their mouths. This is indeed a genius idea. If this kind of electron tube can be manufactured, the volume will be reduced many times, and the power consumption will be reduced at the same time!

For example, the equipment in this room may be compressed into a box!

There were all electronic experts present. They immediately began to imagine how to design this kind of electron tube.

Xierik's crossing, without golden fingers, the knowledge reserves of future generations in his brain are his biggest treasure! Gorin, on the other side, has long been familiar with strange things. Hilrick's head is full of strange things!
