Abstract (en)
[origin: WO2019048319A1] The present invention relates to a turbopump comprising a fixed casing (12, 12'; 112) comprising a pump (16, 116) with a pump rotor (14, 114) borne by a pump shaft (18, 118) and a turbine (22, 122) housing a turbine rotor (20, 120) borne by a turbine shaft (24, 124). According to the invention, the pump shaft (18, 118) is separate from the turbine shaft (24, 124) and the turbopump comprises a speed-varying device (26, 126) for generating a difference in rotational speed between the pump shaft (118, 118) and the turbine shaft (24, 124).
