Rapid Parametric CAx Tools for Modelling Morphing Wings of Micro Air Vehicles (MAVs)
Aerospace, 2023 This paper shows a series of tools that help in the research of morphing micro air vehicles (MAVs). These tools are aimed at generating parametric CAD models of wings in a few seconds that can be used in aerodynamic studies, either via CFD directly using the model obtained or via wind tunnel through rapid prototyping with 3D printers.

Learning Pose Estimation for UAV Autonomous Navigation and Landing Using Visual-Inertial Sensor Data [PDF]
, 2020 In this work, we propose a robust network-in-the-loop control system for autonomous navigation and landing of an Unmanned-Aerial-Vehicle (UAV). To estimate the UAV’s absolute pose, we develop a deep neural network (DNN) architecture for visual-inertial ...
