20250179976. Gas Turbine Engine Ha (General Electric)
GAS TURBINE ENGINE HAVING A HEAT EXCHANGER LOCATED IN AN ANNULAR DUCT
Abstract: a heat exchanger positioned within an annular duct of a gas turbine engine is provided. the heat exchanger extends substantially continuously along the circumferential direction and defining a heat exchanger height equal to at least 10% of a duct height. an effective transmission loss (etl) for the heat exchanger positioned within the annular duct is between 5 decibels and 1 decibels for an operating condition of the gas turbine engine. the heat exchanger includes a heat transfer section defining an acoustic length (l), and wherein an operational acoustic reduction ratio (oarr) is greater than or equal to 0.75 to achieve the etl at the operating condition.
