Abstract
A method of filtering air entering the intake opening of a gas turbine engine. A straightening tube provides a straight channel for incoming air flow. A flow redirector provides a path for air flow that is at right angles to the channel provided by the straightening tube and that leads to the intake opening of the engine. A filter at the downstream end of the flow redirector has a pair of rollers for unrolling and re-rolling a roll of adhesive tape, with an exposed section of the adhesive tape blocking the downstream end of the flow redirector and capturing particles in the air flow. The rollers are activated as needed to expose fresh sections of tape.
