Performance evaluation of reduced-chord rotor blading as applied to J73 two-stage turbine 4: over-all performance of first-stage turbine with reduced-chord rotor blades at inlet conditions of 35 inches of mercury absolute and 700 R
Description: Report presenting a study of the first stage performance characteristics of the two-stage turbine from the J73 turbojet engine. The reduced-chord first-stage turbine operated at a peak brake internal efficiency of over 91 percent at a stage overall pressure ratio of 1.4 and at 90 percent of the design equivalent speed. The unit exhibited high efficiency over a wide range of operating variables.
