Saean R&D (Saean Group Inc - SEAN) Secures Three Additional Key Patents for Next-Generation Air-Jet-Powered UAM, Targeting the $1.5 Trillion Global Urban Air Mobility Market

• Establishes a dense 'patent wall' spanning foundational structures, vortex guidance, and vortex generation
• Addresses limitations of conventional propeller systems with technologies designed for high-speed flight and lower urban noise
• Builds a proprietary technology ecosystem aimed at the UAM market, projected to reach $1.5 trillion (approximately KRW 2,000 trillion) by 2040

HANAM, South Korea and LAS VEGAS, July 21, 2026 /PRNewswire/ -- As the global urban air mobility (UAM) market enters a period of rapid growth, Saean R&D Co., Ltd. (Inventor: Jung-yong Lee), a company specializing in eco-friendly future mobility, has secured an expanded portfolio of core air-jet propulsion patents designed to strengthen its competitive position in the next-generation UAM market. According to global financial services firm Morgan Stanley, the global UAM market is projected to reach approximately $1.5 trillion (around KRW 2,000 trillion) by 2040.

According to patent records from the Korean Intellectual Property Office (KIPO), Saean R&D recently secured three additional related patents covering air-jet propulsion vehicles and aerodynamic control technologies.

The secured patents include:

1. AirJet Propulsion Apparatus for Urban Air Mobility and Air Jet Vehicle
2. Air Jet Propulsion Apparatus Having Vortex Guiding Vane and Air Jet Vehicle
3. Vortex Generation Type Jet Propulsion Apparatus and Air Jet Vehicle

Based on a unified air-jet propulsion framework, these patents create an integrated technology platform that addresses key challenges in UAM commercialization, including structural stability, propulsion efficiency, and noise reduction.

Addressing Open-Propeller Limitations: A Foundational Air-Jet Propulsion Platform for High-Speed Flight

The first patent, which covers the foundational structural technology, is designed to address the technical limitations of the multicopter, or open-propeller, systems that currently dominate the UAM market. It introduces an internally integrated jet-propulsion system optimized for urban environments to improve high-speed cruise efficiency. An external housing also provides an initial layer of acoustic shielding. The company views the technology as a foundation for future expansion into Regional Air Mobility (RAM), which is intended to support high-speed travel between cities.

Preventing Flow Separation and Reducing Noise: Improving Efficiency Through Vortex Control

The second and third patents address energy efficiency and noise, two longstanding challenges associated with jet propulsion.

The Vortex Guiding Vane patent aligns and guides airflow during intake and exhaust to reduce flow separation within the propulsion system. Saean R&D expects the technology to improve propulsion efficiency and reduce battery and fuel consumption.

The Vortex Generation Type patent intentionally creates controlled micro-vortices around the aircraft, helping maintain control and reduce the risk of aerodynamic stall during high-angle flight or sudden maneuvers. It also disperses exhaust flow from the jet nozzle, which could help reduce jet noise, a major challenge for aircraft operating in urban environments.

Building a Dense 'Patent Wall' to Strengthen Technology Protection and Accelerate Market Expansion

The company says the coordinated patent portfolio is designed to form a robust 'patent wall' that makes it more difficult for competitors to design around or replicate the underlying technologies.

With this core air-jet-propelled UAM patent portfolio, Saean R&D aims to establish its own technology standards in advanced air mobility. The company plans to accelerate commercialization and technical cooperation with major domestic and international investors, as well as global aviation partners.

Business Description

Saean is pursuing new mobility projects including the high-performance EXOD electric sports car, 30-ton electric tipper trucks, and the midsize WiD-U electric SUV. The company has also developed the H-drone, an EV and ESS battery power pack equipped with an environmental sensor, and Hydro-LPG technology as part of its alternative-power program. Saean's primary R&D center is located in South Korea.

Saean R&D (Saean Group Inc - SEAN) Secures Three Additional Key Patents for Next-Generation Air-Jet-Powered UAM, Targeting the $1.5 Trillion Global Urban Air Mobility Market

- Contributing to Singapore's sustainable digital infrastructure initiative -

TOKYO and SINGAPORE, Sept. 29, 2026 /PRNewswire/ -- Yokogawa Electric Corporation (TOKYO: 6841) announces that its subsidiary Yokogawa Engineering Asia Pte. Ltd. has joined the Sustainable Tropical Data Centre Testbed Phase 2.0 (STDCT 2.0) Consortium, an initiative led by the College of Design and Engineering (CDE) at the National University of Singapore (NUS). Through participation in this initiative, Yokogawa will leverage its deep industrial automation heritage and leadership in autonomous operations to enhance operational efficiency, asset reliability, and energy optimization across the next-generation data center environments.

Driven by the rapid adoption of generative AI and cloud services, demand for data centers is growing worldwide. At the same time, industry faces significant challenges regarding energy consumption, operational resilience, and workforce constraints. These energy and operational challenges are even more pronounced in tropical regions such as Singapore, where hot and humid conditions place greater demands on cooling systems and energy efficiency, making sustainable data center innovation a crucial matter.

Singapore has identified the data center industry as one of its strategic growth sectors and is advancing plans to develop Jurong Island as a hub for next-generation data centers, an initiative led by government agency for industrial infrastructure, JTC Corporation, with a projected capacity of up to 700 megawatts.

STDCT 2.0 is a testbed initiative that brings together partners from academia, industry, and government to develop and evaluate advanced energy management and cooling technologies and establish a sustainable operating model suitable for AI data centers in a tropical climate. Beyond technology deployment and validation, Yokogawa will also work with the consortium to explore a joint research agenda to address emerging challenges where existing commercial solutions are insufficient to meet the demands of data center operators.

Through its participation in STDCT 2.0, Yokogawa aims to further strengthen its AI-powered technological capabilities and R&D expertise to develop comprehensive solutions that will support Singapore's journey towards a sustainable digital economy and also enhance the efficient and stable operation of AI data centers worldwide.

Professor Lee Poh Seng, Director of STDCT and Head, Department of Mechanical Engineering, College of Design and Engineering at NUS, said, "AI is fundamentally changing the design and operation of data centers. As rack densities rise and infrastructure becomes increasingly complex, improving individual components will no longer be enough, we need to optimize the data center as an integrated system spanning computing, power, cooling, controls and operations. STDCT 2.0 provides a real-world platform to bring these domains together and validate solutions under the demanding conditions of a tropical climate. Yokogawa's deep expertise in measurement, industrial automation and autonomous operations adds an important capability to this effort. Through this partnership, we hope to develop and demonstrate new approaches that make AI data centers not only more energy- and resource-efficient, but also more intelligent, resilient and scalable for deployment in Singapore and other tropical markets."

Kin Wah Chay, President and CEO of Yokogawa Engineering Asia, commented, "This initiative reflects Yokogawa's vision of enabling industrial autonomy and extending our expertise into the rapidly evolving digital infrastructure sector. We are honored to join the STDCT 2.0 Consortium and work alongside leading partners to accelerate and co-innovate solutions for next-generation AI data centers. Leveraging decades of experience in industrial automation and energy management, we aim to help drive smarter, more efficient, and sustainable data center operations in tropical regions."
