Abstract

See full text

In a model jet engine, one or more slide bearings are disposed on one or more turbo shafts. Additionally included are lubricant, a tank system for the latter and an arrangement for supplying lubricant to a respective bearing. The lubricant is incorporated in the propellant of the turbomachine. A propellent-supplying arrangement comprises one or more pump impellers directly coupled to a concerned turbo shaft The tank system is arranged so as to supply propellant to the arrangement without any substantial air/gas element. The arrangement is arranged to operate on the basis of recirculation of the propellent, which can be supplied to the respective slide bearing from the one side of the latter and can be fed back to the tank system from the other side of the slide bearing.
