The Use of Variable Inlet Guide Vanes for Automotive Gas Turbine Engine Augmentation and Load Control 760285

This paper presents the results of the design and development work on variable inlet guide vanes (VIGV) for use in the ERDA Upgraded Automotive Gas Turbine Engine. The feasibility of the concept of VIGV augmentation was carried out on ERDA Baseline engine hardware in compressor rig and complete engine testing.Included in the paper are discussions of this VIGV design philosophy, development logic and test results, and the critical areas of gas generator compressor and turbine matching combined with variable-nozzle power turbine and vehicle matching.
