A gas turbine engine according to an exemplary aspect of the present disclosure includes a windmill pump driven by a spool. A first pump driven by said spool with an air-oil cooler is located downstream of the first pump. A second pump is also driven the spool with an air-air precooler located downstream of the second pump. A method of operating a gas turbine engine during a “windmilling” condition includes driving a windmill pump with a spool during a “windmilling ” condition. A lubricant is communicated to a geared architecture with the windmill pump. ...


1. A gas turbine engine comprising: a spool;a windmill pump driven by said spool through a constant speed transmission;a first pump driven by said spool;an air-oil cooler downstream of said first pump;a second pump driven by said spool; andan air-air precooler downstream of said second pump. 2. The gas turbine engine as recited in claim 1, wherein said constant speed transmission is driven by a towershaft geared to said spool. 3. The gas turbine engine as recited in claim 1, wherein said spool operates at speed excursions of up to 80% between a first con...
