performance calculations for the Rolls Royce Rco.43 Conway 550 aircraft engine

Rolls Royce Rco.43 Conway 550 turbofan engine of 96.97 [KN] (21799 [lbf]) thrust

introduction : 1964 country : United Kingdom importance : **

applications : Vickers VC-10-1151

max. rating (take-off) : 96.97 [KN] (21799 [lbf], 9888 [kgf])

weight engine(s) dry : 2200.0 [kg] = 44.08 [N/kg]

General information :

by-pass ratio : 0.3 : 1

gear ratio : 0.0 : 1

overall pressure ratio (OPR) : 14.1 : 1

rpm HP : 9980 [rpm]

axial flow engine

no water injection

LP compressor stages : 7 [ ]

HP compressor stages : 9 [ ]

HP turbine stages : 1 [ ]

LP turbine stages : 2 [ ]

stages : 7 + 9 + 1 + 2

fan diameter : 110.0 [cm] engine diameter : 0.0 [cm]

air mass flow : 127 [kg/s]

design hours : 1002 [hr] time between overhaul : 501 [hr]

estimated specific fuel consumption (SFC) * (cruise power) :56.1 [kg/KNh]

*SFC = needs more check >

According Wikipedia sfc = 0.874, probably this compares to 89.09 kg/knh
