2Two Turbomeca TM-333-2B2 engines are installed Two Turbomeca TM-333-2B2 engines are installed. The TM-333-2B2 engine is a FADECfree turbine turbo shaft capable of developing up to 801kw (1073 SHP) at take-off rating. Salient features of the engine are detailed below:Power output : 801 kw (1073 SHP) at take off, Sea Level, ISA conditions.Weight : kg. (Dry engine with equipments
4The Advanced Light Helicopter termed as “Dhruv” is a twin-engine, multi-role helicopter of 5.5 tonne class, powered by TM 333-2B2 Turbomeca enginesPower from both engines is fed to the Main Gear Box (MGB) and transmitted to the main Rotor
14Engine Automatic Control - FADEC System (Figure 7.3-5) Each TM 333-2B2 engine is governed by a Full Authority Digital Electronic Control (FADEC) System. There is no ‘cross-talk’ between the left and right engines’ FADECs(except for free-turbine over speed interlock).The FADEC System for each engine consists of:• Digital Electronics Control Unit (DECU), which monitors all ratings and power from STOP to maximum limited value.The DECU box is fitted below the engine deck.• Hydro mechanical system components installed on engine.• Engine sensors.• Helicopter interfaces.
