Two-Shaft Gas Turbine Engine
OSC77FD560MT
Features
-The turbine is a small two-shaft gas turbine engine with a radial flow compressor and axial flow turbine as in the modern power generation industry-The first shaft is a gas negerator
-Inlet air through an orifice flow measuring device is compressed by a single stage radial flow compressor
-The turbine is started by LPG and run on Jet A fuel
-Fuel is injected by a fuel pump and ignighted in the combution chamber providing hot gas for a single stage axial flow turbine
-The hot gas is discharged axially to a larger power turbine on the second shaft and exhausts to atomosphere
-The gas generator unit is complete with automatic front motor starter
-The turbines run on ceramic bePahrointgosgraph includes optional equipment
-Lubricating oil is mixed with fuel, no sepatrate lubrication system to the turbine is required except in the gear box
-An air blower is provided for cooling the engine
-Speed of the power turbine is reduced by an oil cooled gear box
-A hydraulic dynamometer is connected to the gear box by a synchronous belt speed reducer for power measurement
-An Electronic Control Unit (ECU) controls the basic turbine operation
-Additional instruments are provided for monitoring and controlling turbine performance
-A human machine interface (HMI) unit with an input/output module and software are provided for data display and analysis
-Safety features includes shut down for gas generator or power turbine over speed, and high power turbine entry temperature
