An experimental investigation of the XJ35-A-23 two-stage turbine indicated that design performance was not obtained because of losses resulting from large values of exit whirl velocity, an unfavorable choking condition in the second-stage rotor, and limited equivalent work output in the first stage due to choking in the second-stage rotor. A qualitative method of loss evaluation was used to discuss the distribution and causes of the major losses associated with the turbine.
