The turboprop system consists of 3 propeller governors, a governor, and overspeed governor, and a fuel-topping governor. [14] The governor works in much the same way a reciprocating engine propeller governor works, though a turboprop governor may incorporate beta control valve or beta lift rod for beta operation and is typically located in the ...
Some large turboprop engines, such as the original Bristol Proteus and the modern TP400 have free turbines. The TP400 is a three-shaft design, with two compressor turbines and a separate power turbine. Where the turbine is at the rear of the engine, a turboprop engine requires a long drive shaft forwards to the propeller reduction gearbox. Such ...
The T406/AE 1107C Liberty shares a common core with the AE 3007 turbofan and AE 2100 turboprop series of engines, both of which have sold in the thousands of copies. [ 10 ] [ 11 ] 44-46 percent of parts are common between the T406 and the AE 3007, while about 76 percent of parts are common between the T406 and the AE 2100. [ 12 ]

The Lycoming (now Honeywell) LTS101 is a turboshaft engine family ranging from 650 to 850 shaft horsepower, used in a number of popular helicopters, [1] and, as the LTP101 turboprop, light aircraft. Both models carry the US military designation T702 .
The Solar T62 Titan is an American gas turbine engine used mainly as a aircraft auxiliary power unit (APU), conventional power generator, turboprop engine for fixed-wing aircraft or turboshaft engine for helicopters.
The -C20B is typical, with an overall pressure ratio of 7.2:1, at an airflow of 3.45 lb/s (1.8 kg/s), with a power output, at the shaft, of 420 hp (310 kW). One of the latest versions of the Model 250 is the -C40, which has only a centrifugal compressor producing a pressure ratio of 9.2:1, at an airflow of 6.1 lb/s (2.8 kg/s), and develops, at ...
The commercial version of the T407 was the GLC38 (General Electric/Lycoming Commercial 38), which was unsuccessfully offered for several turboprop airliners in the late 1980s and early 1990s. [ 2 ] The new T408 ( GE38-1B ) is slated to power the new Sikorsky CH-53K King Stallion three-engined helicopter for the US Marine Corps.
