Abstract
An air/oil heat exchanger is relatively interconnected to the compressor discharge air or fan discharge air of a fan-jet engine to minimize the size of the heat exchanger core so as to be able to locate the heat exchanger within the intermediate case between struts. The plumbing may be combined with the surge bleed system to simplify the systems and reduce weight and cost.
Claims3
For a fan-jet engine having a fan discharge duct, a compressor having a high pressure compressor section and a low pressure compressor section, fluid connecting means interconnecting the compressor and the fan discharge duct, a heat exchanger located internally of said engine, means for leading a fluid medium intended to be cooled through said heat exchanger and duct means interconnecting said fluid connector means and said heat exchanger for selectively conducting compressor discharge air or fan discharge air to said heat exchanger, valve means for flowing and blocking the flow of compressor discharge air or fan discharge air to said heat exchanger, said fluid connecting means for interconnecting said compressor and fan discharge duct is the connection for the surge bleed system of said engine and a gate valve in said fluid connecting means operable to an open position to spill out compressor discharge air to prevent surge from ensuing.
