Design and Test of a Radial Inflow Turbine for an Advance Liquid Hydrogen Turbopump.

摘要

Pratt & Whitney has developed a high performance Radial Inflow Turbine (RIT) to power the Advanced Liquid Hydrogen Turbopump (ALH) for the Upper Stage Demonstrator engine. The design is based on Pratt & Whitney developed RIT methodology that reduces axial length and tip diameter compared to state-of-the-art RIT's, while maintaining or exceeding existing performance levels. The full power speed is very high delivering ruined power to the pump. Included are the design characteristics and preliminary test results at low speed.
