Abstract
A helicopter comprising a drive having an air intake conduit, a main rotor connected functionally to the drive and a transmission interposed functionally between the main rotor and the drive and housed in a housing. The helicopter further comprises at least one air intake having a first inlet fluidly connected to the intake conduit, at least one second inlet fluidly connected to the housing and deflecting means interacting, in use, with an airflow to divide the airflow into a first and a second airflow. The air intake also has guide means for guiding the first airflow along a first path extending from the deflecting means to the first inlet, and for guiding the second airflow along a second path separate from the first path and extending from the deflecting means to the second inlet.
