MILTHRUST [LBS]
MAXTHRUST [LBS]
idlen1 [%]
maxn1 [%]
betarangeend[%]
if ThrottleCmd < betarangeend/100.0 then engine power=idle, propeller pitch
is controled by ThrottleCmd (between MINPITCH and REVERSEPITCH).
if ThrottleCmd > betarangeend/100.0 then engine power increases up to max reverse power
reversemaxpower [%]
max engine power in reverse mode
maxpower [HP]
psfc power specific fuel consumption [pph/HP] for N1=100%
n1idle_max_delay [-] time constant for N1 change
maxstartenginetime [sec]
after this time the automatic starting cycle is interrupted when the engine
doesn't start (0=automatic starting not present)
startern1 [%]
when starting starter spin up engine to this spin
ielumaxtorque [lb.ft]
if torque>ielumaxtorque limiters decrease the throttle
(ielu = Integrated Electronic Limiter Unit)
itt_delay [-] time constant for ITT change
(ITT = Inter Turbine Temperature)
