Countries cooperate to install a limited number of nuclear and hydrogen bombs on the surface of the moon through phased-array technology detonation.
The shock wave generated will be concentrated to the moon's core, triggering lunar fusion and the disintegration of the moon.
"The moon has never been seen in the past, but the moon used to shine in the past."
Since then, the Earth has embarked on a lonely wandering journey.
I believe that many of our partners have such questions after watching the movie.
What is "phased array" technology?
Why is it able to maximize the effect of limited nuclear weapons?
The concept of phased array originates from the arrangement of the vibration elements of the radar antenna to improve the effect of signal gain. Simply put, it uses the interference principle of nuclear blast shock waves, the primary condition for interference to occur is the same frequency of each wave source, thus enhancing the energy superposition enough to cause nuclear fusion inside the moon, thus blowing up the moon.
Phased arrays, as a radar alignment principle, were applied early in the military radar field. Ordinary radars often need to rotate their own antennas in order to scan a sector or area on a circumference to form a regional display on the radar screen. Phased array radar, on the other hand, uses a radar array to achieve the purpose of scanning an area by controlling the phase difference of radar waves on each small antenna in the radar array.
In recent years phased array technology in the industrial field is increasingly mature, in the special equipment inspection is also often applied to phased array technology, next we will take you to understand the phased array inspection technology.
Make detection easier, make the world safer!
Composition of phased-array inspection device
The phased-array ultrasonic inspection system consists of inspection equipment and equipment, where the inspection equipment includes the instrument host, array probe, sweeper, encoder, simulation software, connection cables and other components, and the equipment includes workpieces, test blocks and coupling agents.
The basic principle of phased array detection technology and the applicable object
Based on the principle of phase delay control, through multiple piezoelectric wafers, forming a one-dimensional array probe, each wafer can be individually excited as an independent array element, using the control of the excitation sequence and delay of the wafer to achieve the deflection of the acoustic beam and focus to complete the focus of the relevant area detection, to achieve the detection of specific angles and depth areas within the workpiece under test, and based on the resulting echo data for imaging, to achieve nondestructive detection and evaluation of defects. detection and evaluation of defects.
Phased-array ultrasonic inspection has a wide range of applications.
In terms of materials, it can be used for metals, non-metals and composite materials.
In terms of manufacturing process, it can be used for forgings, castings, welded parts, glued parts, etc.
In terms of shape, it can be used for plates, bars, tubes, etc.
In terms of size, the thickness can be as small as 1mm or larger than several meters.
In terms of defect area, it can be both surface defects and internal defects.
Advantages of phased array inspection technology
①Defects are displayed as images, which are intuitive and recordable with good repeatability.
②Faster phased-array ultrasonic inspection.
③Phased-array ultrasonic inspection has a high detection rate for hazardous area-type defects (cracks, unfused, underwelded).
④ relative to ray detection, phased-array ultrasonic inspection can provide information on the depth of the defect and its own height, which can be measured, and the determination of defects is more comprehensive.
⑤ phased-array ultrasonic inspection is safe and radiation-free relative to radiographic inspection, and can carry out various tasks with colleagues in the nearby area, effectively guaranteeing the progress of the project and enhancing inspection benefits.
Visual comparison of defect images
This is a tubular butt weld specimen with an unwelded defect at the root of the weld, let's see how its defect imaging differs under different inspection techniques.
Weld root imperfection specimens
After the ray detection and phased array detection can be obtained obvious defect display image. Relatively speaking, phased-array inspection has a more diverse display and digital image storage, which can observe the direction of defects from different directions and realize the three-dimensional positioning and quantification of defects.

How is it used for inspection?
See the demonstration below~
"To do a good job, you must first use a good tool"
To make the equipment effective,
first set up the basic conditions for inspection and commissioning accordingly.
Performing "Sound Velocity Calibration"
and "Angular Compensation (ACG)"
followed by the creation of the "TCG curve"
Complete encoder calibration
and process verification on test blocks
Once all set up is complete
you are ready to use phased array detection technology
to test the equipment on site.
