FIELD: ventilation and air conditioning.
SUBSTANCE: anti-icing system for air intake consists of crossed pylons and transverse sectors connecting pylons. Pylons and sectors are made of tightly connected panels (1–1, 2–1) and covers (1–2, 2–2), on inner surfaces of which there are inner profiled grooves, forming a network of channels. Cross-section of channels is variable. In places of channels turning, channel cross-section area increases. On panels (1–1, 2–1) and covers (1–2, 2–2) of pylons and sectors in all zones of front edges of washed surfaces there are calibrated holes, having an elongated shape, connected to a network of internal profiled channels.
EFFECT: high efficiency of preventing formation of ice on various surfaces in air channels.
