Engine Start Begins with ATS. The Air Turbine Starter (ATS) is a key component of an aircraft's secondary power system, driven by Bleed Air supplied from the Auxiliary Power Unit (APU) to accelerate the engine up to approximately 8,900 RPM, enabling engine start. Through the in-house development and localization of the ATS, we have incorporated power generation, optimal design of the shear section with consideration of failure, Containment functionality, as well as lubrication and power transmission systems. In addition, we have secured manufacturing and assembly technologies and continue development aimed at successful operation and the establishment of a mass production system.

The AB-U60 is a 60-kg class vectored-thrust eVTOL aircraft designed for surveillance and emergency logistics. Developed in response to the growing global demand for disaster response and urgent logistics solutions, the AB-U60 can be adapted for a variety of industries, including wildfire monitoring, anti-drone operations, and ship resupply. It combines an advanced fanjet electric propulsion system with a hybrid energy source to achieve high-speed flight and extended endurance. Airbility’s AB-U60 provides key advantages over competitors, offering high-speed flight of up to 250 km/h and vertical takeoff and landing capabilities for operations in confined spaces. Its low-noise fanjet propulsion system makes it suitable for both urban and suburban missions. The aircraft is also equipped with real-time data analysis and AI-based autonomous flight control systems. These features enable more efficient and safer operations.

The illuminated reticle provides smooth and reliable targeting, even in low-light conditions like dawn or dusk. Whether in dynamic or harsh environments, the ACTUS® ARKS18 is the ultimate riflescope to meet the needs of users who require top-tier performance when it matters most.

Our XR-based aircraft maintenance simulator is officially certified by the Ministry of Land, Infrastructure and Transport (MOLIT) of South Korea for training and education. It provides specialized training environments for the A321, B737-MAX, and B737-800NG aircraft, featuring over 80 detailed modules—including procedures for engine removal, main landing gear installation, and more. This subscription-based simulator is fully compatible with smartphones, tablets, and wearable XR devices, enabling seamless access through a cloud-based web service. Users can train anytime, anywhere—perfect for both remote learning and remote maintenance scenarios. Compared to traditional classroom learning, the XR platform is 4 times more effective and requires only one-third the training time. It also improves user confidence in real-world technical applications by up to 275%. By transforming traditional paper manuals into immersive, interactive training environments, the simulator delivers the next generation of aircraft MRO education for both civil and defense sectors.
