A gas turbine engine in which a portion of the air moved by the first stages of the compressor bypasses the combustion chambers of the engine and mixes with the hot gases in the tail pipe. A turbofan engine is a bypass engine.
Industry:Aviation
A gas turbine engine operating curve which shows the relationship between the compression ratio of the engine and the mass airflow that must be maintained through the engine.
Industry:Aviation
A gas turbine engine that has both centrifugal and axial-flow compressors.
Industry:Aviation
A gas turbine engine that has only one rotating mass.
The compressor is directly connected to the turbine, and everything rotates at the same speed. A twin-spool turbine engine has a low-pressure compressor driven by one turbine and a high-pressure compressor driven by another. The two compressors are linked only by the air that flows through them, and they turn at different speeds.
Industry:Aviation
A gas turbine engine whose rated thrust is expressed in terms related to its engine pressure ratio (EPR).
Industry:Aviation
A gas turbine engine whose rated thrust is produced at a specified RPM.
Industry:Aviation
A gaseous oxygen system in which the oxygen is carried in steel cylinders under a pressure of approximately 450 psi. Low-pressure oxygen systems were used in military aircraft during World War II, but these systems have been replaced by high-pressure systems or liquid oxygen (LOX) systems.
Industry:Aviation
A gas-filled diode electron tube used in a high energy capacitor-discharge ignition system for a turbine engine. The discharge tube blocks all electron flow until the voltage across its electrodes builds up to the ionization voltage of the gas inside the tube. When this voltage is reached, the gas ionizes and the tube conducts, discharging the capacitor through the high-voltage transformer.
Industry:Aviation
A gas-filled, glow-discharge electron tube. A regulator tube is installed in parallel with the load across the output of a DC power supply. The regulator tube maintains a constant voltage across its terminals, even as the current flowing through it changes.
Industry:Aviation
A gasoline-type fuel used in most military jet-propelled aircraft. Jet-B fuel has a flash point of 0°F and a freezing point of –76°F. Jet-B fuel is similar to the military JP-4 fuel.
