A recently granted patent (Publication Number: US11919632B2) discloses an innovative air mobility device designed with compression motors, wings, and blowers to generate propulsion. The main body of the device houses compression motors that create compressed air, which is then directed into rotatable wings with open spaces. The wings have blowers installed at the open spaces to increase propulsion by drawing in the compressed air. Each wing consists of two panels forming an inner space for circulating compressed air, with discharge holes to release the air, enhancing the device's aerodynamic efficiency.

Furthermore, the patent details the connection between the wing panels to facilitate airflow distribution and rotation for vertical or horizontal flight. Driving motors are integrated into the main body to adjust the wing positions, while the compression motors correspond to each wing panel. The device's unique design allows for vertical flight when the wings are upright and horizontal flight when they are laid down. Additionally, the asymmetrical streamlined shape of the wing panels and the specific positioning of the panels contribute to the device's flight capabilities. The patent also mentions the provision of multiple wings and blowers for enhanced performance, showcasing a comprehensive approach to air mobility technology.
