ABSTRACT:
A cylindrical type automotive barrier filter is adapted to be used in the inlet airflow of a gas turbine engine that is used in an agricultural aircraft. Air is drawn in through an inlet in the upper portion of the aircraft nose body without appreciable disturbance to the aerodynamic contours. The outlet of the filter is connected to a duct in a sealed relationship to direct the airflow to the engine inlet. The airflow passage is sealed by a connecting flange mounted on the filter to which the duct is connected. A longitudinally extending firewall is constructed to separate the filter and connecting duct from the turbine section of the engine. An emergency bypass door is provided to provide an inlet airflow in the event the filters become clogged. The bypass door is designed to provide particle separation of the incoming air.
