Structural Response Analysis of a Composite Multirotor Airframe

Abstract

In this work, finite element analyses determine the modal frequencies and relative stiffness of two multirotor airframes---the Camflight FX-8 and its water-resistant variant BG-200.

Details of the analysis procedure are included: Development of 3D models, definition of composite airframe materials, and setup of simulation cases. Future simulations are facilitated by describing the simulation workflow and identifying key considerations.

Static structural analyses indicate a substantial increase in stiffness from the FX-8 to BG-200 model, also represented in the modal simulations. Areas of stress concentration and critical components in both designs are identified for future studies. Overall results also form a basis for assessing future structural improvements; Some recommendations for such are also supplied.
