A system is provided for cooling the undercowl environment of a gas turbine engine having a high pressure compressor and a core gas stream. An electronically controlled compartment cooling valve is controlled as a function of corrected fan speed, altitude, ambient conditions, extreme hot day temperatures and the aircraft environmental control system. A cooling manifold distributes cooling air in the undercowl environment. A regulator, such as an on-off control valve, modulates the amount of undercowl cooling flows as a function of any of a variety of con...
[What is claimed is:] [1.]an electronically controlled compartment cooling valve, the valve being controlled as a function of predetermined parameters comprising corrected fan speed, altitude, ambient conditions, a predetermined temperature and an aircraft environmental control system operating state;a control unit connected to the electronically controlled compartment cooling valve for receiving as inputs the predetermined parameters to control the electronically controlled compartment cooling valve; anda cooling manifold for cooling air distribution in...
