South Korea's Sambo Motors Group has unveiled the HAM III-2 at CES 2025, marking a significant advancement in urban air mobility (UAM). This two-seater hybrid aircraft surpasses its predecessor in size, performance, and technological sophistication. The HAM III-2, designed for multiple passengers, boasts a wingspan of 9 meters, a height of 4.5 meters, and a weight of 850 kilograms. With a hybrid powertrain, it aims to redefine fuel efficiency and flight safety in the UAM market. One notable feature of the HAM III-2 is its dual power system, utilizing battery power for vertical takeoff and transitioning to hydrogen-powered fuel cells for horizontal flight. This design reduces noise, emissions, and weight limitations posed by conventional batteries, enhancing energy efficiency and performance. Equipped with four horizontal propellers for lift and two rear-mounted propellers for forward motion, the aircraft reaches a cruising speed of 112 mph, a range of up to 62 miles, and a flight endurance of 40 minutes, making it ideal for short-haul urban commutes. Sambo Motors is preparing for comprehensive flight tests in the U.S., including hydrogen fuel cell tests in desert conditions to evaluate the aircraft's performance and safety features. This testing phase is crucial as Korea lacks the regulatory framework for hydrogen fuel cell flight tests, prompting Sambo Motors to conduct tests abroad to showcase the aircraft's advantages and promote regulatory advancements domestically. The HAM III-2 is currently undergoing certification processes with Korean and U.S. aviation authorities, with plans for its maiden flight by the end of the year. By integrating hydrogen fuel cells into its powertrain, the aircraft stands out in the UAM sector, offering a practical and forward-thinking approach to urban air mobility. As Sambo Motors pushes the boundaries of innovation in air transportation, the HAM III-2 represents a significant step towards a future of efficient, sustainable, and safe urban air mobility.
