MATHICSE Technical Report : A continuation-multilevel Monte Carlo evolutionary algorithm for robust aerodynamic shape design

Fabio Nobile, Pénélope Leyland, Michele Pisaroni

The majority of problems in aircraft production and operation require decisions made in the presence of uncertainty. For this reason aerodynamic designs obtained with traditional deterministic optimization techniques seeking only optimality in a specific s ...

Bioinspired morphing wings for extended flight envelope and roll control of small drones

Dario Floreano, Stefano Mintchev, Flavio Noca, Grégoire Hilaire Marie Heitz, Matteo Di Luca

Small-winged drones can face highly varied aerodynamic requirements, such as high manoeuvrability for flight among obstacles and high wind resistance for constant ground speed against strong headwinds that cannot all be optimally addressed by a single aero ...

Insect-Inspired Mechanical Resilience for Multicopters

Dario Floreano, Stefano Mintchev, Sébastien Douglas de Rivaz

The ease of use and versatility of drones has contributed to their deployment in several fields, from entertainment to search and rescue. However, drones remain vulnerable to collisions due to pilot mistakes or various system failures. This paper presents ...

Dynamics of a flexible helical filament rotating in a viscous fluid near a rigid boundary

Pedro Miguel Nunes Pereira de Almeida Reis

We study the effect of a no-slip rigid boundary on the dynamics of a flexible helical filament rotating in a viscous fluid, at low Reynolds number conditions (Stokes limit). This system is taken as a reduced model for the propulsion of uniflagellar bacteri ...

Unsteady fluid dynamics around a hovering flat plate wing

Swathi Badala Krishna

Insect flight is characterised by complex time-dependent flows in response to the unsteady wing movements. Biological fliers exploit the unsteady flow fields to modulate aerodynamic forces, thereby displaying unmatched flight performance, especially in hov ...

Human-Comfortable Collision Free Navigation for Personal Aerial Vehicles

Dario Floreano, Felix Stephan Schill, Grégoire Hilaire Marie Heitz, Nicolas Dousse

Semi- or fully-autonomous Personal Aerial Vehicles (PAVs) are currently studied and developed by public and private organizations as a solution for traffic congestion. While optimal collision-free navigation algorithms have been proposed for autonomous rob ...

The effect of the phase angle between the forewing and hindwing on the aerodynamic performance of a dragonfly-type ornithopter

Jamie Paik, Alice Ghislaine Concordel

Dragonflies achieve agile maneuverability by flapping four wings independently. Different phase angles between the flapping forewing and hindwing have been observed during various flight modes. The aerodynamic performance depends on phase angle control, as ...

Optical Thickness Measurements of Vacuum Ultraviolet Radiation in the X2 Expansion Tube

Umar Sheikh

Experiments were conducted in the X2 expansion tube to measure vacuum ultraviolet radiation from shock layers representative of reentry conditions at flight equivalent velocities of 10.0 and 12.2 km/s. Cylindrical models of varying lengths were used to mak ...

Analytical modeling of turbine wakes in yawed conditions

Fernando Porté Agel, Majid Bastankhah

Increasing wind energy production has become a unanimous plan for virtually all the developed countries. In addition to constructing new wind farms, this goal can be achieved by making wind farms more efficient. Control strategies in wind farms, such as ma ...
