Turbomachine with low noise emissions for aircraft
First Claim
1. Turbomachine for an aircraft comprising a gas generator with a combustion chamber and driving at least one fan, said turbomachine being provided with an annular fan duct through which secondary air circulates from the upstream side towards the downstream side of the turbomachine, characterised in that the gas generator is designed such that hot gases are ejected from the combustion chamber towards the upstream side of the turbomachine, and in that the turbomachine also comprises a plurality of hollow mixer struts connected to an output from the gas generator through which hot gases can pass, each mixer strut comprising an output mixer portion located inside the annular fan duct so as to mix the secondary air and the hot gases ejected by these output mixer portions towards the downstream side of the turbomachine.
