Abstract
The starting device for a turbine engine unit of a helicopter includes an electric motor starter, supplied from an electrical power source, which can be outside the helicopter and temporarily connected to the starting device through a connection socket, or onboard on the helicopter. The starter is supplied with alternating current and includes an alternating current electric motor, preferably an auto-controlled synchronous motor, and the onboard electrical power source is preferably an alternator driven, during independent starting, from an auxiliary power unit with a turbo-machine and itself started by direct current batteries.
