1. An aircraft, comprising:
- a variable pitch propulsor; and
an electrical network comprising;
a wound field synchronous AC electrical generator having a wound rotor driven by an internal combustion engine;
a voltage regulator configured to regulate an output voltage of the wound field synchronous AC electrical generator by varying an electrical current provided to a winding of the wound rotor to adjust magnetic field strength of the winding; and
a synchronous AC drive motor coupled to the variable pitch propulsor and provided with power from an output of the wound field synchronous AC electrical generator.

Abstract
An electrical network for an aircraft. The aircraft includes at least one variable pitch propulsor. The electrical network includes a wound field synchronous AC electrical generator having a wound rotor driven by an internal combustion engine. The network further includes a voltage regulator configured to regulate output voltage of the electrical generator by regulating rotor winding magnetic field strength, and a synchronous AC drive motor coupled to a respective variable pitch propulsor and provided with power from the output of the electrical generator.
