Abstract: The disclosure relates to a hydraulic unit of an electrohydraulic gas exchange valve control system of an internal combustion engine. The hydraulic unit includes a hydraulic housing having a receiving opening, a piston guide, and a slave piston. The piston guide is fastened in the hydraulic housing by way of self-staking with a wall of the receiving opening. The piston guide includes an outer part that brings about the self-staking and an inner part that guides the slave piston. An inner surface of the outer part is radially interspaced from the outer surface of the inner part in an axial region of the self-staking and the outer part and the inner part are connected in an axially form-locked manner so that a first end section of the outer part facing the gas exchange valve is partially or fully formed into an outer circumferential recess of the inner part.

Abstract: An aircraft has a propulsion unit and a fuselage unit. The propulsion unit has a first rotor for providing a propulsion force on the aircraft. The fuselage unit extends along a rotation axis of the first rotor and has a rotationally symmetrical shape with respect to the rotation axis of the first rotor. The fuselage unit has a suspension at a first end by which the fuselage unit is coupled to the first rotor so that the fuselage unit is spaced apart from the first rotor along the rotation axis. A detection unit for the detection of environmental information is provided in the area of a second end of the fuselage unit. The propulsion unit is designed to keep the aircraft in a hovering flight condition so that a relative position of the aircraft with respect to a reference point on the Earth's surface remains unchanged.
