An apparatus is designed for preventing entry of foreign objects into an aircraft power plant. The apparatus comprises a rotor kinematically associated with a drive. The rotor is disposed in a duct between an air intake and an engine, and has a center body with radial blades secured thereon. The blades are installed at an angle to the plane which is square with the longitudinal axis of the rotor. The apparatus has a foreign object collection chamber with an opening for entry of foreign objects, disposed in front of the blades in the direction of air flow. The blades are installed relative to one another with an angular pitch determined from the equation: [Figure] where f1 is the dimensionless coefficient dependent on the shape of blades; K2 is the dimensionless coefficient dependent on the ratio of diameters of the duct and center body to the maximum possible air flow rate at the engine inlet; sg
