AQC Flashcards
What is the buffet boundary?
The first point at which buffet is first felt
What is AoA?
Angle between Chord Line and Free Stream air
What is the bypass ratio?
Ratio of total flow at fan stage to total flow at turbine section
What is EPR?
Engine Pressure Ratio: Max cycle pressure to air intake pressure
What is SFC?
Specific Fuel Consumption: Fuel consumed per hour (lbs) ÷ thrust of engine (lbs)
What is a surge?
Aerodynamic instability that causes cyclic reversal - leads to overheating and mechanical damage
What is TGT?
Turbine Gas Temp: Measured between turbine stages
What is EGT?
Exhaust Gas Temp: aka Jet Pipe Temp
Vs
Stall speed

Gross vs Net Performance
Gross: Test aeroplane
Net: Gross adjusted to account for reasonable errors in operational variables
What is screen speed and screen height?
Speeds assumed at 35ft above the runway after take off and 30ft above for landing to establish the field performance of the aeroplane
