A turbine designed in such a way that it is driven by forces produced by the velocity, rather than the pressure, of the gases flowing through the vanes. Velocity turbines are used on turbocompound engines as the power recovery turbines (PRTs).
Industry:Aviation
A turbine driven by the exhaust gases from several cylinders of a reciprocating engine. Energy extracted from the exhaust gases by the turbine is coupled, through a fluid clutch, to the engine crankshaft.
Industry:Aviation
A turbine engine lubricating system in which the oil cooler is in the scavenge subsystem. The oil leaves the engine, passes through the cooler, and then goes into the supply tank.
Industry:Aviation
A turbine or stage of turbines in a gas turbine engine that is not used to drive the compressor in the gas-generator section of the engine.
A free turbine may be used to drive the reduction gears for the propeller in a turboprop engine, or the transmission and a rotor of a helicopter. Free turbines are also used in industrial turbine engines to drive pumps or generators. Free turbines are sometimes referred to as free power turbines.
Industry:Aviation
A turbine stage machined from a single slab of steel. The disk and blades are an integral unit.
Industry:Aviation
A turbine turned by a fluid flowing through it in a direction approximately parallel to the shaft on which the turbine wheel is mounted.
Industry:Aviation
A turbofan engine in which the fan moves more than four times as much air as is moved by the core engine compressor. This type of engine is said to have a bypass ratio of more than
4:1.
Industry:Aviation
A turbofan engine with a bypass ratio of between 2:1 and 4:1. This means that the fan moves two to four times as much air as the core engine.
