First Claim
1. A vertical take-off and landing aircraft (100, 101, 102, 103) for transporting people or loads, comprising:
- a plurality of electric motors (3, 3a-m) and propellers (2, 2a-f) arranged essentially in one surface, a separate one of the electric motors being allocated to each of the propellers for driving the propellers;
a plurality of attitude sensors (8a, 8aa-an) for attitude control of the aircraft (100, 101, 102, 103) provided in active signal connection to a plurality of signal processing units (8b, 8ba-bn); and
a plurality of rotational speed controllers (8da-8dm) each respectively connected to an electric motor of the plurality of electric motors,wherein each said signal processing unit is configured to automatically perform attitude control based on measurement data of the attitude sensors by controlling a rotational speed of at least one of the electric motors (3, 3a-m), so that the aircraft is always positioned essentially horizontally in space with a surface defined by the propellers (2, 2a-f) without control inputs of a pilot or a remote controller,wherein the electric motors (3, 3a-m) and the propellers (2, 2a-f) are arranged in at least a basic hexagonal pattern.

Abstract
A vertical takeoff and landing aircraft (101) for transporting persons or loads, including a plurality of preferably equivalent and redundant electric motors (3) and propellers (2), substantially arranged in one surface, wherein each propeller is assigned an individual electric motor to drive the propeller, the aircraft being characterized in that at least one attitude sensor is provided for attitude control of the aircraft (101) in an active signal connection to at least one signal processing unit which is designed or set up to automatically perform the attitude control based on measurement data from the attitude sensor by regulating the speed of at least some of the electric motors (3), preferably with signal actions of the speed controller assigned to each electric motor such that the aircraft (101) is positioned in space with the surface defined by the propeller (2) substantially horizontal at all times, without control input by a pilot or a remote control.
