ABSTRACT:
The disclosed regulating system is intended for incorporation in two-shaft gas-turbine engine for a road vehicle, wherein a hydraulically controlled torque-transmitting device is interposed between the respective shafts of the turbocompressor and of the power turbine. The system includes in all-speed governor of the rpm value of the turbocompressor. The metering device of this governor is cut into the hydraulic line controlling the torque-transmitting device and is controlled itself by signals coming from a pickup responsive to the rpm value of the turbocompressor. The mechanism for tuning this pickup is operatively connected with the "gas" pedal. The system further includes a fuel feed governor included into the fluid supply line of the engine and controlled by the pressure downstream of the compressor. The system also includes an all-speed governor of the rpm value of the power turbine shaft comprising a metering device included into the fuel supply line of the engine and controlled by signals coming from a pickup responsive to the rpm value of the power turbine shaft. The tuning mechanism of the last-mentioned pickup is operatively connected with the tuning mechanism of the pickup responsive to the rpm value of the turbocompressor, for timed variation of the tuning of these two pickups. The disclosed system provides for stable running of the engine at low loads and throughout coasting and engine braking periods, as well as reliable regulation of the maximum angular speed of the turbocompressor and stable operation of the latter in the minimum speed duty, with disengaged torque-transmitting device.
