Abstract
A cooling system including a gas turbine engine compressor configured to generate an air stream and compress at least a portion of air contained in the air stream. The cooling system further includes at least one air filter configured to filter the air stream upstream from the gas turbine engine compressor, and at least one heat exchanger configured to provide cooling. The at least one heat exchanger is located in the air stream generated by the gas turbine engine compressor at a position downstream of the at least one air filter and upstream of the gas turbine engine compressor.
