A drive-brake arrangement for a wheel of an electric bicycle includes a motor () with a stator () and a disk-shaped rotor (). The stator () is connected directly or indirectly to a frame part () and encloses the rotor () in an at least partially annular manner. The rotor () has permanent magnets () and is connected operatively to a drive shaft () for conjoint rotation therewith. The rotor () has a rotational speed nand the drive shaft () has a rotational speed n. A brake caliper () is mounted on the frame part () and encloses a brake disc () in an at least partially annular manner. The brake disc () is connected operatively to the driveshaft () for conjoint rotation therewith. The rotor () is connected operatively to the driveshaft () via a planetary transmission () and achieves a transmission ratio i=n/n>1.

Drive-brake arrangement for a wheel, and electric bicycle

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.

Drive system of an aircraft, aircraft and method for operating an aircraft

An aircraft includes a wing having an integrated ducted fan. The ducted fan is equipped with inlet louvers and outlet louvers. The inlet louvers are adjustable between an open position and a closed position by an actuating mechanism.

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.

Aircraft

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.

Aircraft having a ducted fan in the airfoil

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

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.

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.

Aircraft with energy battery for cruise and power battery for take-off and landing

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

A battery system, in particular for a motor vehicle, to a power supply comprising the battery system for an electric machine, in particular a vehicle drive, and to a method for charging the battery system.
