FIELD: transport. ^ SUBSTANCE: proposed emergency power supply comprises ram airflow turbine arranged in aligned housing that makes flow duct and power converter. Power converter can be driven by turbine and is directly coupled with the latter by drive shaft. Turbine appliances that allow its mounting in the housing are arranged to allow turbine spatial position invariable in setting emergency supply to standby mode or operating mode. Emergency supply comprises also at least one air inlet, at least one shut-off element and air outlet. At least one aforesaid shut-off element fairs with aircraft outer outline when emergency supply is in standby mode. Besides emergency supply comprises additional air outlet shut-off element that, in standby mode, fairs with aircraft outer outline, first inlet duct and second inlet duct that het connected to form stream duct. Every first and second inlet ducts features effective cross section smaller than that of stream duct. ^ EFFECT: simple design and faultless operation. ^ 9 cl, 2 dwg |
