Hi,

Could you please clarify the full name and physical meaning of the following parameters:
1.Pt2
2.TAT
3.WFuel
4.VAFN
5.VBV

Thanks!

[adiabatic]

Ambient Conditions:
Pt2 — Total pressure at fan inlet, also known as dynamic pressure (ambient pressure with Mach number effect)
TAT — Total air temperature at fan inlet, again higher than ambient temperature for non-zero Mach number
Actuator Positions:
WFuel — Fuel flow to combustor
VAFN — Variable area fan nozzle
VBV — Variable Bleed Valve

These parameters are measured using sensors on the engine, except Pt2 which is provided by an aircraft sensor.
