ABSTRACT:
A nacelle for a gas turbine engine (10) defines an air intake which is capable of meeting all the engine airflow requirements. The nacelle comprises a cowling (22), fixed upstream and in spaced apart relationship from an engine cowling (16), to define an annular passage (30) therebetween. Each of the cowlings, (22) and (16), have an air intake, (24) and (20) respectively, through which the mainstream flow of air passes into the engine (10). Depending upon the amount of airflow the engine (10) demands at different operating flight conditions air can flow in either direction through the passage (30). The flow in either direction through the passage (30) enables optimisation of both the internal and external nacelle requirements at all the different engine airflow requirements.
