ENGINE SYSTEM • Two Turbomeca TM-333-2B2 engines are installed. The TM-333-2B2 engine is a FADEC • free 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 : 166.5 kg. (Dry engine with equipments • The Advanced Light Helicopter termed as “Dhruv” is a twin-engine, • multi-role helicopter of 5.5 tonne class, powered by TM 333-2B2 Turbomeca engines • Power from both engines is fed to the Main Gear Box (MGB) and transmitted to the main Rotor Start-Up Page • Engine 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.
