    摘要: The invention concerns the field of turbomachines, and more particularly a turbomachine (5a) comprising at least a compressor (8), a combustion chamber (9), a first turbine (10) linked to the compressor (8) by a first rotating shaft (11), a device (13) for actuating said first rotating shaft (11) in order to keep the first turbine (10) and the compressor (8) rotating when the combustion chamber (9) is off, and a lubrication circuit (14) for lubricating the turbomachine (5a). This circuit (14) passes through at least one heat source (15, 15a-15c) capable of heating a lubricant in said lubrication circuit (14) when the first turbine (10) and the compressor (8) are rotating while the combustion chamber (9) is off.

    摘要: The starting system comprises a battery of accumulator cells (110), a DC starter (120), an electronic regulator computer (142), a transmission relay (162), starting accessories (168) and a gas generator (160) itself comprising a compressor (164), a combustion chamber (165) and a high-pressure turbine (166) as well as a free turbine (167). First and second circuits are mounted in parallel and interposed between the battery of accumulator cells (110) and the DC starter (120). The first circuit comprises a DC/DC converter (130) mounted in series with a first circuit breaker (132) and the second circuit comprises a second circuit breaker (133). Furthermore, the system comprises at least one sensor (163) sensing the rotational speed of the compressor (164), a sensor (151) sensing the temperature at the inlet of the free turbine (167), and a control circuit (141) controlling the first and second circuit breakers (132, 133) on the basis of the information supplied by the sensor (163) sensing the rotational speed of the compressor (164) and by the sensor (151) sensing the temperature at the inlet to the free turbine (167).
