    摘要： A POWER PLANT HAVING A GAS TURBINE ENGINE WITH SEPARATE GAS GENERATOR AND POWER TURBINE SECTIONS, A TRANSMISSION WITH INPUT AND OUTPUT SHAFTS CONNECTED BY DIFFERENTIAL GEARING, A HYDRAULIC POWER TRANSFER LOOP, AND POWER TRANSFER MEANS BETWEEN THE ENGINE AND THE TRANSMISSION. THE POWER TRANSFER MEANS HAS A FIRST SET OF POWER TRANSFER PATHS SELECTIVELY CONNECTING THE POWER TURBINE WITH THE INPUT SHAFT, AND A SECOND SET OF POWER TRANSFER PATHS SELECTIVELY CONNECTING THE GAS GENERATOR SECTION WITH OTHER PARTS OF THE TRANSMISSION. BOTH POWER TRANSFER PATHS OF EACH SET HAVE GEAR REDUCTION TRAINS OF DIFFERENT RATIOS. CLUTCH MEANS SERVE TO SELECTIVELY RENDER CERTAIN POWER TRANSFER PATHS OF EACH SET EFFECTIVE AT PREDETERMINED TIMES DURING THE OPERATION OF THE POWER PLANT. A HYDRAULIC POWER TRANSFER LOOP, WITH COMBINATION PUMP AND MOTOR COMPONENTS IN MOTIONTRANSMITTING RELATION WITH ELEMENTS OF THE TRANSMISSION AND THE OUTPUT SHAFT, SERVES IN CERTAIN PHASES OF OPERATION OF THE POWER PLANT TO DELIVER POWER FROM THE POWER TURBINE TO THE OUTPUT SHAFT, AND IN OTHER PHASES OF OPERATION FROM THE OUTPUT SHAFT TO THE COMPRESSOR. A TWO-SPEED GEAR SECTION MAY BE EMPLOYED BETWEEN ONE HYDRAULIC COMPONENT AND THE OUTPUT SHAFT TO INCREASE THE EFFECTIVITY OF POWER TRANSFER AT CERTAIN SPEEDS. CONTROL MEANS SERVES DURING ACCELERATION OF THE POWER PLANT TO ACTUATE PARTS OF THE CLUTCH MEANS AT A CERTAIN PERCENTAGE OF THE MAXIMUM SPEED OF THE OUTPUT SHAFT TO RENDER CERTAIN POWER TRANSFER PATHS EFFECTIVE, AND OTHER PARTS OF THE CLUTCH MEANS AT A DIFFERENT PERCENTAGE OF THE MAXIMUM OUTPUT SHAFT SPEED DURING DECELERATION OF THE POWER PLANT TO RENDER THE OTHER POWER TRANSFER PATHS EFFECTIVE.
