[Asia Economy Reporter Ki-min Lee] Hyundai Wia announced on the 19th that it will unveil next-generation landing gear applicable to Urban Air Mobility (UAM) and new weapon systems at the Seoul International Aerospace and Defense Industry Exhibition 2021 (Seoul ADEX 2021).
Seoul ADEX 2021 is the largest aerospace and defense industry exhibition in Korea. Hyundai Wia set up a group exhibition hall together with Kia and Hyundai Rotem.
At this exhibition, Hyundai Wia unveiled for the first time the ground taxiing device for UAM called 'E-Taxiing.' E-Taxiing is a component evolved from the airplane's landing gear that helps facilitate smooth ground taxiing after UAM lands.
Unlike conventional landing gear, Hyundai Wia developed E-Taxiing using an electric motor. It features a separate motor inside the wheel, allowing UAM to operate even when rotors and propellers that provide power are not functioning. This significantly reduces noise during ground taxiing, maximizing passenger safety and convenience. Additionally, it is environmentally friendly as it emits almost no carbon dioxide or nitrogen oxides generated by engines.
The exhibition also showcased a newly developed prototype of a 60mm mortar. The new 60mm mortar weighs about 7.5kg, making it easy to carry and can be fired immediately by hand without a mount. Hyundai Wia developed the new 60mm mortar to significantly reduce weight while maintaining the same range as existing mortars.
Hyundai Wia also displayed the new 81mm Mortar-II. This widely used mortar boasts long firing range and sustained firing capability. All parts, including the barrel, breech, and bipod, use titanium and high-strength aluminum, making it 20% lighter than existing mortars. Notably, target aiming has been changed to automatic observation for more accurate coordinate acquisition. Additionally, 5-inch and 76mm naval guns were exhibited as maritime equipment.
Through this exhibition, Hyundai Wia plans to actively develop and export aerospace and defense products. A Hyundai Wia official said, "In this exhibition, we showcased various products including the 'E-Taxiing,' a key component of UAM, and tube-type mortars, in addition to our existing strengths in medium and large-caliber artillery," adding, "We will continue technological development to contribute not only to overseas exports but also to strengthening our country's defense capabilities."
