Abstract
Abstract ® An air/oil heat exchanger (52) 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 (52) 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
105 words
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 and valve means for flowing and blocking the flow of compressor discharge air or fan discharge air to and from said heat exchanger.
Claim 2
Dependent Claim
105 words
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 and valve means for flowing and blocking the flow of compressor discharge air or fan discharge air to and from said heat exchanger.
Claim 3
Dependent Claim
50 words
For a fan-jet engine as in claim 1 wherein said means for interconnecting said compressor and fan discharge duct is the connection for the surge bleed system of said engine and a gate valve operable to an open position to spill out compressor discharge air to prevent surge from ensuing.
Claim 4
Dependent Claim
53 words
For a fan-jet engine as in claim 2 wherein said fluid connecting means includes a duct-like element having an exit end mounted in the wall of said fan discharge duct, the upstream edge of said duct-like element being contoured to define an aerodynamic lip for flowing fan discharge air into said duct-like element.
Claim 5
Dependent Claim
35 words
For a fan-jet engine as in claim 3 wherein the inlet end of said interconnecting means of said surge bleed system is disposed between said high pressure compressor section and said low pressure compressor section.
