Abstract

A gas turbine aeroengine has an air intake 19 which is designed to be subchoked at a certain known troublesome noise-producing condition, the intake being provided with an extended throat region L whose walls comprise, at least in part, sound attenuating linings 27, 29 of the resonant cavity or bulk absorber type. <IMAGE>
