Investigation of turbines suitable for use in a turbojet engine with high compressor pressure ratio and low compressor-tip speed IV : effect of increasing blade speed on velocity diagrams of turbine for engine operation at constant rotative speed
This is a 1952 NACA technical report by NASA's Technical Reports Server on turbojet turbine design, studying how increasing blade speed changes turbine velocity diagrams at constant rotative speed. The charts are engineering plots of work output, loading limits, required tip diameter and rotative speed against exit annular area, with a separate curve sheet. A designer might take from them only the clean line-graph vocabulary: dashed and solid curves, labelled design-condition points and grid-based technical plotting.
