Abstract
An aircraft compound cooling system includes a power thermal management system for cooling one or more aircraft components, an air cycle system, a vapor cycle system, and a turbine cooling circuit for cooling bleed air and cooling turbine components in a high pressure turbine in the engine. An air to air FLADE duct heat exchanger is disposed in a FLADE duct of the engine and a valving apparatus is operable for selectively switching the FLADE duct heat exchanger between the turbine cooling circuit and the air cycle system. A vapor cycle system includes a vapor cycle system condenser that may be in heat transfer cooling relationship with the air cycle system. An air cycle system heat exchanger and an engine burn fuel to air heat exchanger in the vapor cycle system condenser may be used for cooling a working fluid in a refrigeration loop of the vapor cycle system.
