Investigation of Supercritical (Feher) Cycle

Abstract

Preliminary Design of the XFCTAP 01-01 Combined Rotating Unit (CRU) is described in this report. The unit is intended for the investigation of Supercritical (Feher) cycle engine components. The CRU consists of a single stage axial reaction turbine, a single stage radial pump and a solid rotor alternator with its rotor supported on self-acting radial and thrust bearings with working fluid lubrication. The working fluid is supercritical CO2. Net power output of the CRU is 10 kWe at a design speed of 80,000 RPM. In addition, this report covers the design of an Air Turbine Test Configuration intended to verify the performance of the CRU turbine with compressed air under dynamically similar conditions prior to testing with high temperature supercritical CO2. The air turbine test unit includes an air dynamometer. The turbine is attached to the dynamometer shaft for direct torque measurement. The housing provides means for regulating air flow rate.
