Aerodynamic Performance Benefits of Over-the-Wing Distributed Propulsion for Hybrid-Electric Transport Aircraft

The goal of this study is to analyze how the aeropropulsive benefits an over-the-wing distributed-propulsion (OTWDP) system at component level translate into benefit aircraft level, as well determine whether enhancement sufficient lead a reduction in overall energy consumption. For this, preliminary sizing partial-turboelectric regional passenger performed, and its performance metrics are compared conventional twin-turboprop reference for 2035 timeframe. changes lift, drag, propulsive efficiency due OTWDP estimated simplified unducted geometry using lower-order numerical method, which validated with experimental data. typical cruise condition baseline evaluated experiment, method estimates 45% increase local sectional lift-to-drag ratio wing, expense 12% propeller efficiency. 53% wingspan covered by system, aerodynamic coupling found average 9% 1500 n mile mission. Approximately 4% required offset losses electrical drivetrain. fuel weight compensates powertrain weight, leading takeoff mass comparable aircraft. Overall, 5% consumption found, albeit [Formula: see text] uncertainty modeling alone.
