Lumped Drag Model Identification and Real-Time External Force Detection for Rotary-Wing Micro Aerial Vehicles
Alcherio Martinoli, Lucas Cédric Wälti
This work focuses on understanding and identifying the drag forces applied to a rotary-wing Micro Aerial Vehicle (MAV). We propose a lumped drag model that concisely describes the aerodynamical forces the MAV is subject to, with a minimal set of parameters ...
2024Gas Sensing with Rotary-Wing Nano Aerial Vehicles
Harmful chemical compounds are released daily in warehouses, chemical plants and during environmental emergencies. Their uncontrolled dispersion contributes to the pollution of the atmosphere and threatens human and animal lives.When gas leaks occur, their ...
EPFL2024Distributed Predictive Formation Control of Autonomous Rotary-Wing Micro Aerial Vehicles
This doctoral thesis navigates the complex landscape of motion coordination and formation control within teams of rotary-wing Micro Aerial Vehicles (MAVs). Prompted by the intricate demands of real-world applications such as search and rescue or surveillan ...
EPFL2024The effects of kinematics, flexibility, and planform on the vortex formation and aerodynamic performance of flapping wing flight
In this thesis, the aerodynamic challenges in flapping wing flight are addressed.In particular, the effects of different wing kinematics, flexibilities, and planforms on the the leading edge vortex development and aerodynamic performance are investigated.I ...
EPFL2023Wing and tail morphing in birds and drones
To aid humans in civilian tasks, future drones will have to operate in large cities that abound with difficult flight conditions such as confined spaces, obstacles, and turbulent air. Such drones must cruise efficiently to cover vast distances fast and als ...
EPFL2023Earwig-inspired foldable origami wing for micro air vehicle gliding
Foldable wings serve as an effective solution for reducing the size of micro air vehicles (MAVs) during non-flight phases, without compromising the gliding capacity provided by the wing area. Among insects, earwigs exhibit the highest folding ratio in thei ...
Lausanne2023How ornithopters can perch autonomously on a branch
Flapping wings produce lift and thrust in bio-inspired aerial robots, leading to quiet, safe and efficient flight. However, to extend their application scope, these robots must perch and land, a feat widely demonstrated by birds. Despite recent progress, f ...
Berlin2022Observing the Central Arctic Atmosphere and Surface with University of Colorado uncrewed aircraft systems
Julia Schmale, Radiance Flore Aurore Calmer
Over a five-month time window between March and July 2020, scientists deployed two small uncrewed aircraft systems (sUAS) to the central Arctic Ocean as part of legs three and four of the MOSAiC expedition. These sUAS were flown to measure the thermodynami ...
NATURE PORTFOLIO2022To tread or not to tread: comparison between water treading and conventional flapping wing kinematics
Karen Ann J Mulleners, Alexander Gehrke, Swathi Badala Krishna
Hovering insects are limited by their physiology and need to rotate their wings at the end of each back-and-forth motion to keep the wing's leading edge ahead of its trailing edge. The wing rotation at the end of each half-stroke pushes the leading edge vo ...
IOP Publishing Ltd2022Not gone with the wind: Active microscale flight with highly porous bristled wings
Pedro Miguel Nunes Pereira de Almeida Reis, Yuexia Luna Lin
The finesse of sub-millimeter insect flight with comb-like bristled wings raises intriguing questions, not only on fluid-structure interactions (FSI) but also on the mechanical behavior of the underlying, highly porous structures. Farisenkov et al. charact ...
