Keywords: hydraulic devices, engine compartment, vent components, discharge coefficients

The paper presents experimental investigations of discharge coefficients for the aviation engine compartment hydraulic devices. Vent inlets, vent outlets and compartment ventilation system had been investigated. Investigations had been performed with simulation of the fan flow over the engine hydraulic devices in the range M <= 0.2 …0.5.
