1. An aircraft, comprising: a propeller;an aircraft drive including an internal combustion engine and a transmission, the internal combustion engine coupled to the propeller directly via the transmission and having a drive power to drive the propeller; andan electric machine rigidly coupled with the aircraft drive via a belt drive, wherein the internal combustion engine cooperates with the electric machine, and wherein the electric machine is operated as an electric motor in a first operating mode and as an electric generator in a second operating mode, wherein during electric motor operation the electric machine provides additional drive power amounting to 15 to 35% of a rated power of the internal combustion engine. 2. The aircraft according to claim 1, wherein the electric machine is connected with at least one accumulator as an energy storage device, which provides energy required during electric motor operation and/or can be charged during generator operation. 3. The aircraft according to claim 2, further comprising at least two accumulators which are arranged in wings of the aircraft. 4. The aircraft according to claim 3, wherein at least one accumulator provides energy for an on-board power supply of the aircraft. 5. The aircraft according to claim 1, wherein the electric machine starts the internal combustion engine. 6. The aircraft according to claim 5, wherein the electric machine is connected with a crankshaft of the internal combustion engine rigidly. 7. The aircraft according to claim 6, wherein the electric machine is arranged on the crankshaft between the propeller and the internal combustion engine. 8. The aircraft according to claim 1, wherein the electric machine is coupled to the transmission of the aircraft drive via the belt drive. 9. The aircraft according to claim 1, further comprising a control unit which controls a carburetor or an injection system of the internal combustion engine and charging and power electronics of the electric machine. 10. The aircraft according to claim 9, wherein the control unit is operable by a control element constituting a single-lever control. 11. The aircraft according to claim 10, wherein the control unit automatically switches the electric motor operation of the electric machine on and off and the generator operation of the electric machine on and off in dependence on a position of the control element. 12. The aircraft according to claim 1, wherein the aircraft constitutes a motor airplane, ultralight aircraft, trike, motor glider, glider with auxiliary engine, Light Sport Aircraft (LSA) or Very Light Aircraft (VLA). 13. A method for controlling an aircraft, comprising: during a first flight mode including take-off or climbing flight, operating an engine of an aircraft drive to drive a propeller, the engine coupled to the propeller directly via a transmission of the aircraft drive, andoperating an electric machine as a motor to further drive the propeller, the electric machine rigidly coupled with the aircraft drive via a belt drive, wherein during electric motor operation the electric machine provides additional drive power amounting to 15 to 35% of a rated power of the engine; andduring a second flight mode following the first mode, operating the engine to drive the propeller and selectably operating the electric machine as a generator to store energy in an accumulator. 14. The method of claim 13 further comprising starting the engine with the electric machine. 15. The method of claim 13, further comprising adjusting the engine in response to a single-lever control, and automatically switching the electric motor operation of the electric machine on and off and the generator operation of the electric machine on and off in dependence on a position of the single-lever control. 16. The method of claim 13 further comprising, during other flight modes, decoupling the electric machine from the aircraft drive, wherein the electric machine does not exert a load on the engine when decoupled from the aircraft drive. 17. An aircraft, comprising: a propeller;an aircraft drive including an internal combustion engine, the internal combustion engine mechanically coupled to the propeller and having a drive power to drive the propeller; andan electric machine rigidly coupled with the aircraft drive via a belt drive, wherein the internal combustion engine cooperates with the electric machine, wherein the electric machine is operated as an electric motor in a first operating mode and as an electric generator in a second operating mode, and wherein during electric motor operation the electric machine provides additional drive power amounting to 15 to 35% of a rated power of the internal combustion engine.
