Abstract
A tail cone integrated ram air turbine (RAT) includes a rotatable segment of an aircraft tail cone configured to deploy a set of RAT blades. The tail cone integrated RAT also includes a power transfer shaft connected between the rotatable segment and configured to transfer power to from the rotatable segment to an auxiliary power unit (APU). The tail cone integrated RAT further includes a controller connected to the APU and configured to control power output from the APU. When emergency power for an aircraft is needed, the set of RAT blades is deployed from the rotatable segment of an aircraft tail cone. Mechanical power from the rotatable segment is transferred to an APU generator to produce emergency electrical power.
