Reconfigurable Drone System for Transportation of Parcels With Variable Mass and Size

Dario Floreano, Fabrizio Schiano, Przemyslaw Mariusz Kornatowski, Leonardo Cencetti

Cargo drones are designed to carry payloads with predefined shape, size, and/or mass. This lack of flexibility requires a fleet of diverse drones tailored to specific cargo dimensions. Here we propose a new reconfigurable drone based on a modular design th ...

Flexural-tensegrity snapping tails for bio-inspired propulsion in fluids

Pedro Miguel Nunes Pereira de Almeida Reis, Claudio Boni

Many aquatic animals propel themselves by flapping their tails. Leveraging a recently proposed snapping cantilever beam based on the concept of flexural tensegrity, we propose a bio-inspired propulsion device. The design comprises a segmental beam with hol ...

Bacteria-induced mixing in natural waters

Alfred Johny Wüest, Oscar Rodrigo Sepúlveda Steiner, Talia Ekin Tokyay Sinha

Swimming organisms can enhance mixing in their natural environments by creating eddies in their wake and by dragging water along. However, these mixing mechanisms are inefficient for microorganisms, because swimming-induced variations in velocity, temperat ...

3D T 2-weighted imaging at 7T using dynamic kT-points on single-transmit MRI systems

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Kieran O'Brien, Florent Eggenschwiler

OBJECTIVES: For turbo spin echo (TSE) sequences to be useful at ultra-high field, they should ideally employ an RF pulse train compensated for the B 1 + inhomogeneity. Previously, it was shown that a single kT-point pulse designed in the small tip-angle re ...

Influences of porous reservoir Laplace pressure on emissions from passively fed ionic liquid electrospray sources

Herbert Shea, Daniel George Courtney

Passively fed ionic liquid electrospray sources are capable of efficiently emitting a variety of ion beams with promising applications to spacecraft propulsion and as focused ion beams. Practical devices will require integrated or coupled ionic liquid rese ...

ACTIVE MODEL ROCKET STABILIZATION VIA COLD GAS THRUSTERS

Gautier Marie Pierre Rouaze, Anton Ivanov, Xavier Collaud, Raimondo Pictet, Danylo Malyuta, Mikael Martins Gaspar

This paper describes the development and testing of a reaction control system (RCS) for a model rocket named FALCO-4. The rocket uses cold gas jets to keep itself perfectly vertical at low speeds. We first describe the mechanical layout of FALCO-4 and the ...

Overview of MAST results

Jonathan Graves, Wilfred Anthony Cooper, Mario Ludovico Podesta, Jan Horacek, Ben McMillan, Ricardo Pérez Suárez, Otto Asunta

The Mega Ampere Spherical Tokamak (MAST) programme is strongly focused on addressing key physics issues in preparation for operation of ITER as well as providing solutions for DEMO design choices. In this regard, MAST has provided key results in unders ...

Propulsion and Instability of a Flexible Helical Rod Rotating in a Viscous Fluid

Pedro Miguel Nunes Pereira de Almeida Reis

We combine experiments with simulations to investigate the fluid-structure interaction of a flexible helical rod rotating in a viscous fluid, under low Reynolds number conditions. Our analysis takes into account the coupling between the geometrically nonli ...
