Turbomachine ignition device and ignition method

The thermal turbomotor has a housing (80), combustion chamber (30) and an ignition system (10). For the ignition, an air feed (70) and a fuel feed (60) lead to an ignition zone (50) with ignition (51). The ignition zone is linked to the combustion zone by an ignition tube (40), for the ignition of the combustion chamber from outside the housing.
