Powerplant
turboprop engine
Aviation; Aircraft maintenance
A turbine engine in which several stages of turbines are used to extract as much energy as possible. The turbines drive reduction gears which in turn drive a propeller.
turboshaft engine
Aviation; Aircraft maintenance
A turbine engine in which several stages of turbines are used to extract as much energy as possible. The turbines drive shafts which are used to drive helicopter rotors, generators, or pumps.
cold-tank lubrication system
Aviation; Aircraft maintenance
A turbine engine lubricating system in which the oil cooler is in the scavenge subsystem.
hot-tank lubricating system
Aviation; Aircraft maintenance
A turbine engine lubricating system in which the oil cooler is located in the pressure subsystem. The oil is returned to the tank without being cooled.
air impingement starter
Aviation; Aircraft maintenance
A turbine engine starter that basically consists of a nozzle that blows a stream of compressed air against the turbine blades to rotate the compressor for starting the engine.
ultra-high-bypass (UHB) engine
Aviation; Aircraft maintenance
A turbine that drives a pair of ducted or un-ducted contrarotating propellers which have eight to 12 variable-pitch blades. These blades are very thin, have wide chords, and are swept back with a ...
axial turbine
Aviation; Aircraft maintenance
A turbine that is turned by a fluid flowing through it in a direction that is approximately parallel to the shaft on which the turbine wheel is mounted.
