IL-114 EnginesThe aircraft is equipped with two TV7-117C turboprop engines with electronic system of automatic controldeveloped by Klimov's plant (St. Petersburg) with Aerosila plant's (Stupino) propellers CB-34. Structurally the engine is made in modularsystem and consists of 9 modules. The replacement of modules does not require additional balancing and can be implemented in airportconditions. Two-channel electronic system of regulation is used in the engine (hydro mechanical management ensures the end of flight in caseof refusal of plane's electronics). The independent onboard monitoring system provides the control of parameters and provides the crew withinformation about malfunctions and gives recommendations for their elimination. The system also allows carrying out operative on the groundafter flight control of engines. The fuel usage efficiency of the engine is provided with high parameters of a thermodynamic cycle (degree ofcompression - 16, temperature of gas in front of the turbine - 1500 K) and with high efficiency of components (compressor efficiency ishigher for 81 %, the efficiency of the turbine of the compressor is higher for 88 %,IL-114Enginesthe efficiency of the free turbine is higher for 92 %,completeness of combustion of the chamber of combustion is 0.99). The engine has the big capacity of gas dynamic stability. Design Features:axle -centrifugal force compressor consisting of five axial and one centrifugal steps; the entrance directing device and directing devices offirst two steps are adjustable; reverse-flow chamber of combustion; 2step axial turbines of the compressor with four cooling rings; 2 stepaxial free turbines; shaft of capacity selection; coaxial reducer of the screw, which is located in front of the compressor.

IL-114-100 EngineThe aircraft is equipped with two PW-127H turboprop engines produced by "Pratt & Whitney Canada" withpropellers HS 568 F-7 of "Hamilton Sundstrand" (USA). Three-roll turboprop engine with independent turbine consists of two centrifugalcompressors, the counter flow ring chamber of combustion. Two axial one-stage turbines rotate rotors of compressors. The independent turbine- axial two-level. Turbines of compressors and the independent turbine are connected among themselves with only gas dynamic connection. Thesystem of automatic control of the engine consists of electronic, hydro mechanical regulators and a regulator of spin-up restriction of theair screw. A reducer is planetary, differential, closed type with a measuring instrument of twisting moment. The engine is equipped withthe system of electronic management with the program of automatic increase of capacity from normal take-off up to maximal take-off, and alsowith the fuel pump, the systems of regulation of submission and heating of fuel, the system of ignition without power supply, the indicatorof a shaving in oil, the regulator of spin up restriction and a lay brake of the air screw. The air screw is six bladed with the hydraulicmechanism of change of double action blades' step and balance weights.IL-114 Engine иммиграция ЭквадорTogether with the controlling systems of the air screw and the engine, it provides automaticmaintenance of constant frequency of rotation, its given change, drafts reversing and feathering of the air screw. Connection of the airscrew with a power shaft of the engine is flange-mounting. Blades of the air screw are sword type with a graphite longeron, covering suppliedwith lightning protection aluminum grid, nickel overlay on the forward edge and electro heaters in the forward edge ensuring the protectionagainst an icing.
