When gases pass through a convergent duct their:
velocity decreases and their temperature and pressure increase.
velocity increases and their temperature and pressure decrease.
velocity and temperature increase and their pressure decreases.
The highest pressure in a gas turbine engine occurs:
between the compressor and the combustion chamber.
In the combustion chamber.
In the jet pipe.
Gas turbine engine efficiedby increases with:
a decrease in ambient temperature.
a decrease in ambient pressure.
an increase in ambient temperature.
The bypass ratio of an engine is the ratio of:
exhaust gas pressure to air intake pressure.
cold stream air to that flowing through the hot core of the engine.
Primary air to secondary air.
The gas turbine engine uses the principle of:
Newtons Third Law of motion.
Newtons First Law of motion.
creating thrust equal to the weight of the aircraft.
The fan in a turbofan engine, is driven by:
The rearmost turbine.
The high pressure turbine.
The intermediate pressure turbine.
The majority of the thrust of a
turbo-fan engine comes from the by-pass air.
Turbo-fan engine comes from the turbine exhaust.
Turbo-prop engine comes from the turbine exhaust.
A pitot intake forms a _______ duct _______the fan to ensure that the airflow______ to _______ and achieves a _______ _______ .
divergent; before; slows down; subsonic; pressure rise
divergent; before; speeds up; sonic; pressure drop
convergent; before; speeds up; subsonic; pressure rise
In a pitot intake the term Ram Pressure Recovery refers to the time when:
Intake pressure has been re-established to ambient pressure.
EPR has attained the take off setting.
EPR has recovered to its optimum figure.
