Investigation of turbines suitable for use in a turbojet engine wtih high compressor ratio and low compressor-tip speed V : experimental performance of two-stage turbine with downstream stator

摘要

An experimental investigation of a highly loaded two-stage turbine with a downstream stator revealed that (1) at equivalent design work and speed the brake internal efficiency was 0.81 and the maximum efficiency obtained was 0.85, and (2) the downstream stator left very little energy in the form of tangential velocity in the gas and, in general, performed well with 0.78 recovery being obtained at equivalent design work and speed.
