FIELD: protective devices for transport facilities and stationary protected objects. SUBSTANCE: the protective device uses a protective rotating screen, drive and framework. The novelty is in the fact that the protective screen is made as a circle rotating about the central axis and has two parallel steel austenite plates fastened to each other; the space between the plates is filled with fibrous material with a high mechanical resistance to penetration of projectiles, and a layer of ceramic balls is placed inside this material. EFFECT: enhanced reliability. 2 dwg |
