SWINGING DOOR PARTICLE SEPARATOR AND DEICING SYSTEM Abstract of the Disclosure In a gas turbine engine, a duct is constructed extending axially and communicating directly, through a transverse opening, with the engine plenum. The plenum extends upward into the engine nacelle and connects with the inlet to the compressor of the gas turbine engine. A portion of the air entering the duct is drawn into the plenum. The remainder is exhausted out of the rear portion of the duct. To create inertial separation, a door is mounted on a lever arm which may be rotated between two positions. In one position the door partially closes the entrance to the plenum causing the airflow to turn through a greater angle in order to enter the plenum. The turning motion of the airflow divides the particles of heavier mass to the outside of the turn. These particles will be exhausted from the rearward exit of the duct. In a second position the door closes the rear portion of the duct so that the entire volume of air entering the duct is supplied to the engine plenum.
