carbon track
Aviation; Aircraft maintenance
A trail of carbon deposited by an arc across a high-voltage component such as a distributor block. Carbon tracks have a relatively low resistance to the high voltage and can cause ...
built-in test equipment (BITE)
Aviation; Aircraft maintenance
A troubleshooting system installed in many modern jet aircraft. BITE equipment monitors engine and airframe systems, and when a fault is found, isolates it and provides ...
toggle
Aviation; Aircraft maintenance
A T-shaped handle fitted onto the end of a cable used to engage a simple starter with an overrunning clutch.
poppet valve
Aviation; Aircraft maintenance
A T-shaped valve with a circular head. Poppet valves are used to cover the intake and exhaust openings in the cylinder head of a reciprocating engine. The valves are held closed ...
beta tube
Aviation; Aircraft maintenance
A tube in a Garrett TPE331 turboprop powerplant that extends into the propeller pitch control to act as a followup device. It provides movement of the propeller blades in ...
power recovery turbine (PRT)
Aviation; Aircraft maintenance
A turbine driven by exhaust gases from several cylinders of a reciprocating engine. Energy extracted from exhaust gases by the turbine is coupled, through a fluid clutch, to the ...
velocity turbine
Aviation; Aircraft maintenance
A turbine driven by forces produced by the velocity, rather than the pressure, of gases flowing through the vanes.
