| 摘要 |
The turbo-pump consists of a large-diameter rotary shaft (22) carrying a high-pressure turbine (5) which forms a single pump stage to receive the liquid fuel through a suction duct (3) and deliver it under pressure through a feed duct (4). It has one bearing (23) to support the shaft (22) in a zone of reduced section situated in front of the turbine (5).There is a fluid bearing (24), able to withstand a high speed of rotation, situated in a zone of large section to the rear of the turbine, and at least one turbine stage (32, 33) to the rear of the fluid bearing. A high-pressure inductance fan (31) is situated in front of the bearing (23), and the turbo-pump is equipped with cast metal housing sections (1, 2, 38) of simple shape. ADVANTAGE - Simple and compact design, with reduced manufacturing costs.
