EDMing turbopump blisks

Aircraft Engineering and Aerospace Technology, 2002
Turbine blisks designed for advanced liquid rocket engine turbopumps are usually of a timed structure with twisted blades, and they can be machined effectively with the electrical discharge machining (EDM) process. After the machining specifications have been designated, the EDM process of a turbopump turbine blisk is discussed, in which the kernel ...

65 Years of Turbopumps

Vakuum in Forschung und Praxis, 2023
SummaryVacuum technology is not necessarily one of the sciences mentioned in connection with groundbreaking inventions. Nevertheless, it is a basic prerequisite for many developments and products that are taken for granted today. The influence of vacuum technology on our lives today can be traced back to the invention of the turbopump 65 years ago ...

Simulation of Cavitating Flows in Turbopumps

41st Aerospace Sciences Meeting and Exhibit, 2003
Simulations of a cavitating inducer at design flow conditions are reported in this paper. The ability of a Navier-Stokes based, multiphase formulation in modeling the effects of large-scale extensive cavitation on the performance of inducers is demonstrated. The simulations were performed on the Simplex inducer geometry that has been extensively tested

Health Monitoring System of Turbopump

41st AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2005
In order to enhance the safety of large Liquid propellant Rocket Engine (LRE), a TurboPump Health Monitoring System (TP-HMS) was developed in this paper. Based on the research of turbopump vibration feature selection and system design principle, the Subsystems of Test Hardware (THS), Real-Time Fault Detection and Alarm (RT-FDAS), Post-Test Data ...
