What is claimed is: 1. A method of operating a gas turbine engine, comprising:(a) burning a fuel in a turbomachinery core to produce a first flow of pressurized combustion gases;(b) extracting energy from the first flow of pressurized combustion gases and using the energy to generate a first flow of pressurized air with a rotating fan;(c) rotating the fan at a constant speed at a maximum RPM in all flight conditions;(d) selectively varying a flow area through the fan to vary the first flow of pressurized air while the fan rotates at the constant speed; a...
