lean die-out
Aviation; Aircraft maintenance
A condition in which the fire in a gas turbine engine goes out because the fuel-air mixture ratio is too lean to sustain combustion.
rich blowout
Aviation; Aircraft maintenance
A condition in which the fire in a gas turbine engine goes out because the fuel-air mixture ratio is too rich to sustain combustion.
overboost
Aviation; Aircraft maintenance
A condition of excessive manifold pressure in a reciprocating engine. Overboosting occurs when the supercharger is operated at too high a speed.
vapor lock
Aviation; Aircraft maintenance
A condition of fuel starvation that can occur in a reciprocating engine fuel system. If the fuel in the line between the tank and carburetor is heated enough for the fuel to ...
flameout
Aviation; Aircraft maintenance
A condition of turbine engine operation when the fire unintentionally goes out. Improper fuel-air mixture or interruption of the air flow through the engine can cause a flameout.
surge
Aviation; Aircraft maintenance
A condition of unstable airflow, through the compressor of a gas turbine engine, in which the compressor blades have an excessive angle of attack. Surge usually affects an entire ...
two-stroke cycle
Aviation; Aircraft maintenance
A constant-volume cycle of energy transformation that completes its operating cycle in two strikes of the piston, one up and one down. When the piston moves up, fuel is pulled ...
