Abstract: An aircraft includes a wing having an integrated ducted fan. The ducted fan is optionally equipped with inlet louvers and outlet louvers. The inlet louvers and the outlet louvers are adjustable between an open position and a closed position.

Abstract: An aircraft includes a wing having an integrated ducted fan. The ducted fan is enclosed at least in sections by a feed lip. The feed lip has a flat curvature on the bow side and a comparatively strong curvature on the rear side.

Abstract: An aircraft includes a wing that is extended through by a ducted fan having movable louvers.

Abstract: An aircraft includes a short-range radar that is configured to detect a trajectory, which is specified based on a position detection of the aircraft by a ground station.

Abstract: A drive system of an aircraft, including a fuel cell, which can be supplied with hydrogen from a hydrogen tank and with air from a blower, the fuel cell being configured to provide drive power for operational flight after takeoff and before landing dependent on a hydrogen mass flow supplied by the hydrogen tank and dependent on an air mass flow supplied by the blower, and an electrical energy store, which is configured to provide additional drive power for takeoff and landing, wherein an additional hydrogen tank and an air or oxygen tank are configured to interact with the fuel cell such that the fuel cell can be supplied with an additional hydrogen mass flow and with an additional air or oxygen mass flow, thereby compensating at least partially for a loss of the additional drive power provided by the electrical energy store for landing.

Abstract: An aircraft has an energy battery, a power battery, lifting rotors and cruise propellers and is configured such that the energy battery supplies the cruise propellers in cruising phases and the power battery supplies the lifting rotors in take-off and landing phases. The aircraft also includes a reserve power battery. The reserve power battery is configured to selectively supply power to the lifting rotors in an emergency. The reserve power battery is rechargeable, and, during the cruising phases, the energy battery is configured to charge the power battery and the reserve power battery.

Abstract: An aircraft includes a fuselage and propellers, wherein the propellers can be retracted beneath the fuselage.

Abstract: An aircraft has a ducted fan having a duct with an electrical machine integrated into it.

Abstract: A power supply for an aircraft includes a drone capable of flight and including rotors, a DC-to-DC converter, a battery for driving the rotors and a locking device for securing a plug connection between the drone and the aircraft. The drone is set up to secure the plug connection by the locking device until the aircraft reaches a prescribed altitude, and the power supply is configured in such a way that the battery supplies power to the aircraft by the DC-to-DC converter as long as the plug connection exists.
