Abstract
An improved synchrophasing system for synchrophasing fan spools and engine core spools of one or more 'slave' turbofan engines to a 'master' engine is disclosed. A fuel control means is provided for modulating the flow of fuel to the slave engines to first synchrophase the operation of the engine fan spools. A variable stator vane control means is provided for then modulating the position of variable stator vanes within the slave engines to synchrophase the operation of the engine core spools.
