Whirl Flutter for Distributed Propulsion Systems on a Flexible Wing

AIAA SciTech Forum

Abstract

View Video Presentation: https://doi.org/10.2514/6.2022-1755.vid Propulsion system configurations of novel aircraft designs, incorporating multiple propellers at various wingspan positions, can potentially lead to aeroelastic instabilities, which need to be considered at an early stage of design. An aeroelastic framework is proposed to consider rigid propellers flexibly attached to a flexible wing to generically represent unconventional aircraft design concepts. A parameter study is offered to demonstrate the sensitivity of aeroelastic instabilities on the number and positions of installed propellers.
