PT6 Engine Operating PT6 Engine Operating Parameters Parameters The PT6A engine is a free turbine engine and is also The PT6A engine is a free turbine engine and is also one of the main variants of the PT6 engine. We all one of the main variants of the PT6 engine. We all wish that was an economic statement instead of a wish that was an economic statement instead of a description of a type of compressor / propeller description of a type of compressor / propeller relationship. relationship.

slide 3:

Combustion And Cooling Combustion And Cooling The free turbine compressor is designed to offer the The free turbine compressor is designed to offer the necessary compressed air to the hot section of a PT6A necessary compressed air to the hot section of a PT6A engine for use in fuel-air mixture/combustion and engine for use in fuel-air mixture/combustion and cooling. The compressor’s speed in Revolutions Per cooling. The compressor’s speed in Revolutions Per Minute RPM is controlled by hot gases flowing through Minute RPM is controlled by hot gases flowing through the compressor turbine vane ring and power turbine the compressor turbine vane ring and power turbine vane ring. These vanes have a specified class number vane ring. These vanes have a specified class number which shows their ability to flow these gases. which shows their ability to flow these gases.

PT6 Engine PT6 Engine These class sizes and the condition of the compressor itself These class sizes and the condition of the compressor itself figure out the speed of the compressor of PT6A at any given figure out the speed of the compressor of PT6A at any given power setting. The class size range for a particular engine is power setting. The class size range for a particular engine is determined by the manufacturer’s technological innovation. determined by the manufacturer’s technological innovation. The speed of a gas generator is set or fixed to limits during The speed of a gas generator is set or fixed to limits during engine overhaul testing or at engine manufacturer. The engine overhaul testing or at engine manufacturer. The compressor delivers sufficient air pressure for cooling and compressor delivers sufficient air pressure for cooling and combustion to allow the engine to develop the required combustion to allow the engine to develop the required horsepower/torque. horsepower/torque.

slide 5:

Compressor’s Efficiency Compressor’s Efficiency Since this free turbine compressor is not connected Since this free turbine compressor is not connected mechanically to the propeller through the power mechanically to the propeller through the power section what happens when it gets dirty or damaged by section what happens when it gets dirty or damaged by foreign objects. The damage or contamination reduces foreign objects. The damage or contamination reduces the compressor’s efficiency and results in a higher gas the compressor’s efficiency and results in a higher gas generator speed for the same power setting. The pilot is generator speed for the same power setting. The pilot is targeting on Torque and RPM when he applies power. targeting on Torque and RPM when he applies power.

slide 6:

Gas Generator Speeds Gas Generator Speeds Hot weather will result in faster gas generator speeds due to Hot weather will result in faster gas generator speeds due to the reduced air density at high temperatures. Assume your the reduced air density at high temperatures. Assume your engine’s NG speeds have crept up to just beyond the Red Line engine’s NG speeds have crept up to just beyond the Red Line and a compressor Performance Recovery Wash did not and a compressor Performance Recovery Wash did not restore the previous settings. Now you are retarding the restore the previous settings. Now you are retarding the throttle at taking off to keep from over-speeding the gas throttle at taking off to keep from over-speeding the gas generator. This outcome in less power available not a good generator. This outcome in less power available not a good circumstance in the middle of an AG spray season. circumstance in the middle of an AG spray season.

Maintenance Manual Maintenance Manual cautions cautions The Maintenance Manual cautions to install the same class The Maintenance Manual cautions to install the same class size vanes when replacing compressor turbine or power size vanes when replacing compressor turbine or power turbine vanes. The airflow specifications on these vanes for turbine vanes. The airflow specifications on these vanes for any PT6 engine any PT6 engine are determined and tested in the test cell. are determined and tested in the test cell. Before deciding to re-class an engine on-wing all Before deciding to re-class an engine on-wing all possibilities for repair should be exhausted because of possibilities for repair should be exhausted because of recognized inadequate efficiency. recognized inadequate efficiency.
