A flying car refers to an automobile that can travel both on roads and in the sky

⚫ A flying car means an automobile that can run on the roads and fly in the air. In a broad sense, a flying car refers to a next-generation means of transportation having the functions of a car and an airplane

⚫ A flying car is also called a (PAV), Urban Air Mobility (UAM), Air Taxi, and manned drone

Flying cars have various forms depending on the driving method and the takeoff and landing methods

⚫ Flying cars are classified into single mode (flying) and dual mode (flying+driving) flying cars depending on the driving method, and into Conventional Takeoff and Landing (CTOL), Short Takeoff and Landing (STOL), and Vertical Takeoff and Landing (VTOL) depending on the takeoff and landing methods

⚫ Flying cars are classified into internal combustion engine, battery power, and fuel cell types depending on the driving energy, and into fixed-wing, rotary-wing and multicopter* types depending on the wing shape

* A multicopter refers to a rotary-wing flying car that has two or more rotors (rotary wings)

< Trend of Flying Car Development in Korea and Other Countries >

⚫ Before 2015, flying cars were developed and tested mainly by some innovative start-ups ⚫ Since 2015, large car manufacturers, airplane manufacturers, and IT companies having manufacturing capabilities and capital strength have positively entered into the development of future-oriented high value-added flying cars and the business of Air Taxi service ⚫ Recently, the flying car companies prefer the 'e-VTOL' type, which causes less noise and has an advantage in urban mobility, and have plans to commercialize flying cars in 2023 to 2030

Securing original technologies for core components and systems is necessary to develop flying cars that can safely fly in urban areas as environment-friendly mobility

➊ Development of high-safety, high-output, high-energy density, and high-discharge rate battery pack

∎ The energy density of the currently available battery packs for EVs is about 150 to 180 Wh/kg. Future flying cars will require an energy density of 230 Wh/kg or higher

➋ Development of high-efficiency, ultra-light, low-noise electric propulsion system

∎ Future urban flying cars require a 150 kW high-torque lightweight motor, a high-output motor control inverter, and a 500 kg-thrust, high-performance, low-noise prop-rotor

➌ Development near-integrity safety system similar to large-sized civilian aircraft

∎ Multiple propellers should be used to prevent a fall even when one or two of them is out of order. Also required are a three-dimensional object perception and collision avoidance system, an automatic flight system, and an impact-minimizing system (parachute, etc.) to protect passengers even in the worst case (fall)

Mobility Insight, March 2020, Vol. 3 7 Mobility Insight Technology Review

➍ Development of Brake/Steer-by-Wire technology and module coupling-separation apparatus to develop dual mode and modular flying cars

The cooperation among industry, university, and government-funded institutes and the support from the government are urgently needed to foster the flying car industry in Korea and secure international technological competitiveness

⚫ Promotion of close cooperation among automobile and aircraft industry, university, and government-funded institutes, and collaborative development of technologies

∎ Synergic effects will be produced when the automobile companies having the xEV electric power system and battery technologies and the aircraft companies having the prop-rotor, communication, air-traffic control, and automatic flight technologies cooperate together with the industry, university, and government-funded institutes

⚫ Support from competent government departments (Ministry of Land, Infrastructure, and Transport, Ministry of Commerce, Industry and Energy, Ministry of National Defense, etc.) and improvement of relevant laws and systems

∎ Laws and systems relevant to flying car in Korea: Aviation Safety Act, Airport Facilities Act, Aviation Business Act, Aviation Security Act, Aviation and Rail Accident Investigation Act, Aerospace Industry Development Promotion Act, etc

⚫ A system for evaluating the performance, safety, and reliability of essential components, systems, and complete flying cars should be established early in Korea to perform the evaluation in each of the development stages of various types of flying cars
