Regional Passenger Aircraft Type of An-158 with a Hybrid Propulsion Parametric Concept

This study proposes a concept for the design and development of a modification of the An-158 regional passenger aircraft equipped with a hybrid propulsion system. The propulsion configuration includes two turboprop engines and two electric engines, with multidirectional propellers positioned symmetrically at the wing tips. This innovative design reduces wingtip vortices, decreasing inductive drag and improving aerodynamic efficiency. Parametric analyses were conducted using the modular software systems “Integration 2.1” and “Propeller 2.2” for typical flight profiles of the An-158. Despite the added weight from hybrid components, the modified aircraft design demonstrated reduced fuel consumption and harmful emissions in taxiing, takeoff, and climb modes. These findings highlight the potential of hybrid propulsion to enhance environmental performance while maintaining operational efficiency.
