Abstract

A method (100, 100a, 100b) of calibrating an engine core (11) of a gas turbine engine (10), wherein the engine core (11) comprises a turbine (19), combustion equipment (16), a compressor (14), and a core shaft (26) connecting the turbine (19) to the compressor (19), the core shaft (26) arranged to drive a propulsive fan (23) of the gas turbine engine (10), the method (100, 100a, 100b) comprising: providing (102) a resistance load (62) on the core shaft (26), the resistance load (62) arranged to replicate the load of a propulsive fan (23); driving (104) the engine core (11); measuring (106) a performance parameter or the engine core (11); measuring (108) a thrust generated by the engine core (11); and determining (112) power rating data of the engine core (11), providing a correlation between the performance parameter and the thrust.
