According to reports, 3D printing technology seems to be gradually infiltrating into every corner of life. Russia intends to use 3D printing technology to manufacture drones, and one of the new amphibious drones is believed to take off and land on soft surfaces, swamps, water surfaces, snow and other complex surfaces. It can be used by both military and civilians and can carry passengers. Do you dare to try?

"Perspective Russia" reported on the 22nd, the state-owned Russian technology group company to create a prototype of a drone with 3D printing technology, weighing 3.8 kg, wingspan 2.4 meters, flying speed of 90 to 100 kilometers, endurance 1 to 1.5 hour.
Company spokesperson Vladimir Kutahof said that the company achieved a leap from concept to prototype in two and a half months. The actual production took only 31 hours and the manufacturing cost was less than 200,000 rubles (about 3,700 US dollars). ).
"Perspective Russia" did not mention the code and model of this drone in the report. However, according to the Xinhua International client, according to a report submitted by Kutahov to an unmanned aerial vehicle international conference in April, the company is using 3D printing technology to manufacture an amphibious drone with air cushion device, codenamed Chirok. , Russian means water duck.
At the time, Kutahov introduced the application of 3D printing technology in the aerospace and space fields as the chief project engineer of the Russian technology group, and the advantages of using this technology to manufacture drones.
According to his statement at the time, the conceptual model of "Water Duck" has been completed and can be put into prototype manufacturing. The first full-size "water duck" prototype weighs about 750 kilograms and is expected to be unveiled at the Moscow Air Show in August this year. It is still impossible to confirm whether the prototype of this drone reported by "Perspective Russia" is "water duck".

"Russia Today" TV station previously reported that the "water duck" is unique in that it does not require any special take-off and landing sites, and can take off and land on any surface, regardless of snow or drainage.
The air duck's air cushion can be retracted in flight mode, while the information about its power system is confidential and not publicly available. This amphibious drone can be used to transport supplies to hard-to-reach areas as well as military purposes.
The "water duck" can fly at a height of 6,000 meters, with a controllable range of 2,500 kilometers and a payload of 300 kilograms. It can take 2 to 3 passengers and their luggage, or carry inspection and monitoring equipment.
Russian media analysis, "water duck" is most likely to be used in civil areas such as environmental monitoring, mountain fire detection, transportation, search and rescue. Taking into account the modest body shape and the characteristics of the whole body composite material, the "water duck" has the same stealth ability, can carry offensive weapons such as small guided missiles, high-precision bombs, and can perform reconnaissance missions.
[Innovative Manufacturing]
People are not new to 3D printing, but they don't necessarily know its professional name: additive manufacturing. As a manufacturing technology, 3D printing is not a substitute for traditional manufacturing, but it has the advantages that traditional manufacturing can't match: individualized, difficult, and complex technical features. 3D printing is the gain and supplement of traditional manufacturing, and has obvious advantages in the early stage of design and modeling.
Russian researchers believe that automated design technology has completely revolutionized the entire machinery manufacturing industry, especially the high-tech aviation industry. Manufacturing drones with 3D printing saves design time and shortens prototype manufacturing and production lead times, dramatically increasing new product production speeds. However, the Xinhua International client noted that some experts are concerned that these technologies are not mature enough at the moment and that they may encounter problems when manufacturing aircraft power structural components.
The Russian media commented that the Soviet Union had led the world in the field of drone design, but now Russia is lagging behind international standards in the field of drone manufacturing, and only the tactical reconnaissance drone is available. The Russian government has set an ambitious goal for military enterprises: in 2022, Russia's self-developed and produced UAVs accounted for at least 5% of the global UAV production.
Today's Russian UAV manufacturers are not only interested in military applications, but also on their development prospects in the civilian sector. The application of drones in Russia faces many problems such as aviation safety, legal norms, etc. It will take time to achieve universal promotion.
KMJ SF6 Gas Density Relay
It is applicable for monitoring the SF6 gas density in a sealed vessel. It can show gas density values on the site. When the gas density reaches the preset value, the contact-making device will send alarm and control signals. It can be widely used in electric equipment including SF6-insulated composite apparatus, circuit breakers, pole-mounted switches, transformers and mutual inductors. It provides solutions for new construction of transformer substations and inteligent reconstruction of existing transformer substations.
