Device and method for starting of a helicopter turbine, using an electrical energy source comprising supplementary discharging means

摘要

The device has a starter (6) powered with electrical energy from an electricity network (8). Discharge members (10) i.e. supercapacitors, are incorporated in the electricity network and grouped into a module. The members of the module are grouped by a dozen, and have individual capacitance in the order of 3000 farads for a unit voltage of about 2.7 voltage direct current (Vdc). The members are connected in series to make the module suitable for use on a network having a voltage of about 28 Vdc. The members partially form an accessory that is removably mounted in the electricity network. An independent claim is also included for a method of starting a turbine engine of a helicopter.
