The Korea Association of Stacking Manufacturers (K-AMUG, Chairman Joo Seung-hwan) will be equipped with a jet engine made of metal (3D printing) and start manufacturing drones that can take off and land vertically (VTOL).
K-AMUG announced on February 24 that it held a "3D printing jet engine 100kg drone manufacturing project" and demonstration at Ulsan Venture Building and Ulsan drone airspace located in Ulsan City.
The event was attended by officials from various fields, including smart mobility, and seminars on the necessity and application of drones for 3D printing jet engines △ vertical take-off and landing autonomous airplane models (LTE/5G applications), 1.7m drones equipped with small jet engines △ two 300N jet engines that can be installed on actual planes.
While vertical takeoff and landing aircraft (VTOL) drones are in the midst of commercialization worldwide, eVTOL drones that can be operated in the city center are in the spotlight.
In line with this trend, K-AMUG has manufactured jet engines through additive manufacturing, completed the 1.7m drone "eVTOL" as a prototype to be installed and is on a test flight.
The biggest feature of this drone is that it can be operated at high speed and long distances in a hybrid method that adds electric power as well as jet engine performance, so it can be applied to military drones, smart mobility, air taxis, and transport medical patients.
Currently, more than 2kg can be loaded, and existing jet engines manufactured through additive manufacturing have the advantage of simple maintenance and stable supply of parts because they are manufactured with domestic technology.
In order to commercialize 3D printing jet engine propulsion drones, K-AMUG proposed to promote projects that can transport smart mobility, air taxis, and medical supplies at this briefing session. The goal is to develop vertical take-off and landing drones that can fly for 1-2 hours with a weight of 5-100 kg. It also plans to promote light weight reduction of gas through DfAM (Layer Manufacturing Specialized Design), which is an advantage of additive manufacturing.
As a representative eVTOL application, there are directly collided small drones, which are weapon systems that are increasing in development and introduction worldwide as they can accurately hit key targets and transport military support supplies. Currently, Korea is also pursuing a 500g direct collision small drone development project led by the Civil and Military Cooperation Promotion Agency under the auspices of LIG Nex1 and plans to phase out from 2021 through the military's test and evaluation process.
Earlier, K-AMUG formed a consortium with Hanseo University, drones, and 3D printing companies to develop 3D printing jet engines for the first time in Korea and secure more than five jet engines and operating technologies. The association is making single-person electric airplanes lightweight using 3D printing, and is promoting the production of lightweight aviation parts and the delivery of heavy industry parts.
Meanwhile, the video of this demonstration can be viewed on YouTube by searching for the Korean Stacked Manufacturer Association.
