Abstract: A gas turbine engine according to an example of the present disclosure includes, among other things, a fan section including a fan rotor. The fan rotor includes a fan hub defining a first diameter at a leading edge of a fan blade. The fan blade defines a tip diameter at the leading edge, with a ratio of the fan hub diameter to the fan tip diameter being less than or equal to 0.40. A compressor section includes a low pressure compressor and a high pressure compressor. A turbine section includes a fan drive turbine and a high pressure turbine. The fan drive turbine is configured to drive the fan section, and the high pressure turbine is configured to drive the high pressure compressor.

Abstract: An example variable vane scheduling method includes adjusting variable vanes from a position based on a first schedule to a position based on a different, second schedule in response to a control feature. An example method of controlling flow through a compressor of a turbomachine includes moving variable vanes to positions that allow more flow into the compressor in response to bleed air being communicated away from the compressor.

Abstract: A gas turbine engine has an upstream compressor having an upstream entrance area leading into a first vane upstream of the upstream compressor. A downstream compressor has an exit area at a leading edge of an exit vane for the downstream compressor. The entrance area divided by the exit area is greater than or equal to 13.8 and less than or equal to 15.3.
