AERODYNAMIC CHARACTERIZATION AND MISSION PERFORMANCE ANALYSIS OF A LIGHT SEAPLANE DESIGN

Abstract

This paper presents the modeling, aerodynamic characterization and mission performance analysis of a seaplane design that is based on the AeroVolga Borey, utilizing a baseline Rotax 912 ULS engine configuration. The seaplane, with its amphibious capabilities, plays a critical role in connecting remote regions, yet detailed aerodynamic analyses of such aircraft are scarce. This study aims to address the gaps by focusing on the seaplane's aerodynamic properties and mission performance. A 3D-printed model of the Borey seaplane was tested in an open-loop wind tunnel, providing lift and drag coefficients under various flight conditions. From the experimental results, the highest lift-to-drag ratio was found to be 8.9. The aerodynamic data were then integrated into a mission performance simulation to assess its fuel burn, range and performance in different flight phases. On the whole, the study finds that the resultant aerodynamic and mission performance characteristics are aligned closely with the benchmark design data, highlighting the Borey's big potential as a short-to-medium-range seaplane. The maximum range calculated is 685 km, with error of 7.4% relative to the design specification. Findings from this study further contribute to a better understanding of seaplane performance, with practical applications for seaplane design and mission planning.
