TURBOPUMP WITH SINGLE FLOW INTEGRATED GAVAGE.

摘要

P The turbopump comprises, inside a single casing (102), a main shaft (101) driven by a turbine (103), a secondary shaft (104) coaxial with the main shaft (101), a low pressure impeller (110) mounted on the secondary shaft (104) to create a medium pressure flow which is brought parallel to the axis of the turbopump by a rectifier (111) and deflected by 180degree in a return channel (112) to be brought back parallel to the axis of the turbopump to a high pressure impeller (114) mounted on the main shaft (101) inside the secondary shaft (104). The whole of the HP centrifugal flow formed by the HP impeller (114) is sent towards the interior (133) of curved hollow blades (132) forming part of the impeller BP (110). This HP centrifugal flow creates a motor torque for the BP impeller (110). /P
