Drone

A drone comprising:

• a body;
• and
• a rotor unit;
• wherein the body has a substantially cylindrical outer lateral surface;
• wherein at least one energy storage element of the drone is arranged in the body;
• wherein the rotor unit is connected to a head side of the body;
• wherein the rotor unit comprises a first rotor with first blades and a second rotor with second blades;
• wherein the first rotor and the second rotor are arranged coaxially to each other;
• wherein the first rotor is designed to rotate clockwise about a rotational axis;
• wherein the second rotor is designed to rotate counterclockwise about the rotational axis;
• wherein the first blades and the second blades are mounted so that they can be freely folded, and when folded the first blades and the second blades rest against the body in a rotation-free state;
• wherein a connection of the rotor unit to the head side of the body is configured without a swashplate;
• wherein the rotor unit is connected to the head side by at least a first actuator and a second actuator;
• wherein the rotor unit is mechanically connected to the head side by one first spherical plain bearing;
• wherein a local distance between the head side and the rotor unit is configured to be adjusted by the first actuator and the second actuator, a first change in the local distance by at least one of the first and second actuators causing a second change in an angle between the head side and the rotor unit;
• and
• wherein the first actuator and the second actuator are each spaced apart from a center point of the head side or the axis of rotation, and the first spherical plain bearing is arranged spaced apart from the center point of the head side or the axis of rotation.
