Abstract
An air intake layout for a turboprop. A nacelle surrounding an intake section of the turboprop behind the fan propeller can be moved away from the main part of the nacelle and can be divided into two parts that may be extracted so as to leave full access to the panel leading to equipment in a central compartment, whereas the panel was partially covered by the air intake leading edge.
