Power Plant
The L-159A is powered by the Honeywell/ITEC F124-GA-100 engine, clearly the “Best in Class”. The F124 is a two-shaft, non-afterburning turbofan engine of modular design with three stage LP axial compressor. HP compressor has four axial stages followed by one centrifugal.
High thrust-to-weight ratio provides the aircraft with superior performance and maneuverability. The engine is controlled by dual Full Authority Digital Electronics Control (FADEC) which automatically limits critical engine parameters and offers the pilot “unrestricted throttle movement” together with fast transient time and surge protection. Low engine bypass ratio results in better altitude lapse rate and superior Mach number performance. Modular design of the engine consists of seven basic modules. It provides complete interchangeability between engines that reduces spare count and simplifies maintenance.
Engine Monitoring System
An engine monitoring system (EMS) is embedded in the FADEC to provide data for life management, hardware tracking, and performance trend monitoring. Through computer-aided maintenance EMS reduces engine life cycle and support costs.
Secondary Power System
The secondary power system consists of a SAFIR 5F Auxiliary Power Unit (APU) for ground and in-flight engine start-up. APU also provides emergency hydraulic power for flight control system and drives standby electrical generator.
