FIELD: aerodynamic aircrafts.
SUBSTANCE: invention relates to the design of propellers for aerodynamic aircraft. The propeller contains an air fairing, radial blades and a hub. On the air fairing there are relief reflectors that direct beams of light coming from the lantern towards the blades. The lantern is located behind the propeller on the wing or on the protective casing of the engine. Beams of light coming from the lantern pass between the rotating radial blades and fall on the relief reflectors. Reflected from the relief reflectors, the beams of light then fall on the surface of the radial blades, providing their illumination.
EFFECT: invention is aimed at improving the safety of propeller operation.
