Abstract
The invention relates to a feed device for feeding a thrust chamber () of a rocket engine () with first and second propellants. According to the invention, a first feed circuit () of the thrust chamber () comprises a turbopump () having at least one pump () for pumping the first propellant from a first tank (), and a turbine () mechanically coupled to said pump (). The first feed circuit connects an outlet of the pump to an inlet of the turbine via a heat exchanger () configured to heat the first propellant with heat generated by the thrust chamber, in order to actuate the turbine. According to the invention, a second feed circuit () is configured to feed the thrust chamber with second propellant from a second tank () that is configured to be pressurized. The invention also provides a method of feeding a rocket engine thrust chamber with first and second propellants.
