Design and Optimization of a Large Turboprop Aircraft

This paper proposes a feasibility study concerning large turboprop aircraft to be used as lower environmental impact solution current regional jets operated on short/medium hauls. An overview of this market scenario highlights that segment is evenly shared between and jet aircraft. Although ensure operative flexibility, they are usually not optimized for short missions with negative effect block fuel impact. Conversely, turboprops represent greener but reduced passenger capacity speed. Those aspects highlight slot new platform coupling higher seat capacity, cruise speed design range consumption. should operate those ranges where neither nor existing optimized. work compares three different solutions: high-wing layout under-wing engines installation both two- three-lifting-surface configurations low-wing tail tips-mounted engines. For each concept, multi-disciplinary optimization was performed targeting the minimum 1600 NM mission. Optimum solutions were compared such Airbus A220-300 specifically designed range.
