NACELLE-MOUNTED GAS-TURBINE ENGINE AIR INLET Russian patent published in 2015 - IPC F02C7/05 

FIELD: engines and pumps.

SUBSTANCE: gas-turbine engine system is installed in a nacelle containing an air inlet fairing, which functions as an air inlet, it contains the foreign matter deflector unit, forming together with the air inlet fairing an inlet air passage, and at the outlet of the deflecting unit - a secondary deflecting channel and principal channel of engine air supply. The inlet air passage is designed with a possibility of deflecting, at least partial, of foreign matters sucked into the air inlet, towards the secondary deflecting channel. The secondary deflecting channel is implemented so that the air flow rate, passing through it, increases from inlet to outlet. The secondary channel has an outlet with a hole at the outside wall of the nacelle.

EFFECT: invention is aimed at improvement of engine protection from penetration of foreign matters at keeping of aerodynamic characteristics of the nacelle.
