Embodiments relate generally to systems and VTOL aerial vehicles. An example central server system comprises: at least one central server system processor; and central server system memory storing central server system program instructions accessible by the at least one central server system processor, and configured to cause the at least one central server system processor to: receive vehicle registration data associated with a manned VTOL aerial vehicle; and determine that the vehicle registration data is associated with a manned VTOL aerial vehicle that is authorized to communicate with the central server system. Some embodiments include VTOL aerial vehicles in communication or communicable with a central server system.

A ducted fan device includes: a plurality of fan devices each having a fan configured to be rotated about a first axis to generate an airflow and a cylindrical smaller duct surrounding the fan about the first axis and extending in a first axis direction; and a cylindrical larger duct extending in a second axis direction parallel to the first axis. Each of the fan devices is arranged on an inner side of the larger duct when viewed in the second axis direction. At least a part of the smaller duct is arranged outside the larger duct on an upstream side in a flow direction of an airflow when viewed in a direction orthogonal to the second axis.

The present invention provides a vertical takeoff and landing assistance aircraft which mates with deployable aircraft to assist the deployable aircraft with takeoff and landing. The assistance aircraft may incorporate the use of one or more multi-motor assemblies for enhanced aircraft performance. The vertical takeoff and landing assistance aircraft is designed to allow the deployable aircraft to be mated or fastened to the top portion of the assistance aircraft allowing a top release of the deployable aircraft. The assistance aircraft, upon deployment of the deployable aircraft, drops below the deployable aircraft. The assistance aircraft also includes one or more methods for deployment and recapture of the deployable aircraft.

An electrical power supply system is equipped with a first switching device disposed on a first wire of an electrical power supply circuit, a second switching device disposed on a second wire of the electrical power supply circuit, a third switching device disposed on a third wire that bypasses the first switching device, a fourth switching device disposed on a fourth wire that is connected to the third wire and the second wire, and resistors disposed in at least two portions from among a first portion on the third wire, a second portion on the fourth wire, and a third portion on the third wire.

A power supply system includes a power storage device, a power supply circuit for supplying DC power from the power storage device to a load device, and a containment member for accommodating the power storage device. The power supply circuit includes a positive wire and a negative wire, a first switch provided on the positive wire, and a second switch provided on the negative wire. One of the first switch or the second switch is disposed in the interior of the containment member, and another one of the first switch or the second switch is disposed on the exterior of the containment member.

An electric vertical take-off and landing (eVTOL) aircraft can enhance energy efficiency, safety, and operational range. A deployable wing structure can provide aerodynamic lift during horizontal flight, reducing reliance on energy-intensive propellers. Integrated flexible solar panels capture solar energy, contributing additional power and optimizing energy management. The wing system also includes an emergency descent mode, doubling as a glide-assist device for controlled landings during critical failures. The system offers modular configurations for various missions, ensuring adaptability and improved flight performance. The eVTOL can be implemented with systems and methods for mitigating motion sickness. The systems integrate tactile feedback systems into wearable devices and environmental components. Sensors detect motion and environmental changes, and a computing device can generate corresponding tactile feedback signals. Tactile actuators embedded in the devices or components provide non-visual motion cues, such as pressure, vibration, and haptic feedback, to resolve sensory mismatches between the vestibular and proprioceptive systems.

A moving object includes a moving object main body, a resistance structure which can be switched at least from a retracted state to a deployed state, and a holding structure which holds the resistance structure in the retracted state. The resistance structure includes an engagement recess. The holding structure includes a holding main body portion supported by the moving object main body, and a rotating body configured to be engaged with the engagement recess in the retracted state of the resistance structure. When a force equal to or larger than a predetermined force is applied to the resistance structure, engagement of the rotating body with the engagement recess is released, and the resistance structure is switched from the retracted state to the deployed state.
