1. A gas turbine engine comprising,
a casing accommodating a compressor, a combustor, and a turbine;
bearings being in the casing;
a main lubricator including
an oil mist generator that generates oil mist by mixing oil with compressed air extracted from the compressor and
a first supply passage through which the oil mist is guided to the bearings; and
a starting lubricator including
a second supply passage that is connected to a portion of the first supply passage and through which a gas flowing out from a gas source is guided to a connection portion of the first supply passage, the connection portion being the portion of the first supply passage and
an opener that starts supply of the gas from the gas source through the second supply passage to the connection portion, wherein:
the main lubricator supplies the oil mist through the first supply passage to the bearings by pressure of the compressed air extracted from the compressor; and
when the opener starts the supply of the gas, the starting lubricator supplies the oil mist to the bearings through the second supply passage and a portion of the first supply passage located downstream of the connection portion, by the pressure of the gas flowing out from the gas source.
