Combustion air feeding device for aircraft i.e. helicopter, engine, has air inlet pipelines extended to engines from outer surface, where air feeding of engines is switched to inlet pipelines by control device when air inlets are blocked
The device has an air inlet pipeline (4) connected between an outer surface (5) of an aircraft and internal engines (3a, 3b) and started from air inlets (2a, 2b) in a region of the outer surface. Air inlet pipelines (8a, 8b) extend to the engines from the outer surface for performing dual-channel air flow, and comprise relevant filtering elements (9a, 9b) of an air inlet cover. Air feeding of the engines is switched to the air inlet pipelines (8a, 8b) by a control device when the air inlets are blocked.
