An APU air intake having a foldable intake door, including a frame with airfoil profiles. The frame is turned to an aperture angle (α) with respect to the frame support, and each airfoil profile is turned to a profile angle (βi) with respect to the frame. The aperture angle (α) varies from 0° to 22°, and the profile angles (βi) vary from 0° to 110°. The frame is moved by an actuator and the airfoil profiles are operated by extendable rods and secondary rods each secondary rod having rod supports. A latching mechanism is assembled onto each extendable rod, including a rare earth magnet and either a magnet contact plate or a plate with another magnet.
