Future of flight: From the return of supersonic travel to pods that clip onto planes

Modular aircraft for flexible transportation The modular Clip-Air aircraft decouples the transportation module - a flying wing - from its load - capsules that can carry passengers, freight, or fuel. This project is laying the groundwork for tomorrow’s air ...

Wave propagation in periodic buckled beams. Part I: Analytical models and numerical simulations

Alessandro Spadoni, Florian Paul Robert Maurin

Periodic buckled beams possess a geometrically nonlinear, load-deformation relationship and intrinsic length scales such that stable, nonlinear waves are possible. Modeling buckled beams as a chain of masses and nonlinear springs which account for transver ...

Laser-assisted inkjet printing of highly viscous fluids with sub-nozzle resolution

Demetri Psaltis, Christophe Moser, Paul Delrot, Miguel Antonio Modestino

Drop-on-demand inkjet printing is mostly based on thermal and piezo-actuation, allowing for densely packed nozzles in inkjet printers. However, the droplet diameter is typically defined by the nozzle diameter, thus limiting the range of viscosity that can ...

NANOPARTICLES Production of amorphous nanoparticles by supersonic spray-drying with a microfluidic nebulator

Esther Amstad

Amorphous nanoparticles (a-NPs) have physicochemical properties distinctly different from those of the corresponding bulk crystals; for example, their solubility is much higher. However, many materials have a high propensity to crystallize and are difficul ...

Vortical Flow Patterns for High Lift for High Speed Aircraft Concepts

Pénélope Leyland, Michele Gaffuri

Enhancing detached vortical flow over leading edges and flap surfaces allow high lift configurations in critical regimes of take-off and acceleration. In the context of the FP6 Environmentally Friendly High Speed Aircraft project HISAC, future high speed a ...

Radiation-Ablation Coupling for Capsule Reentry Heating via Simulation and Expansion Tube Investigations

Pénélope Leyland, Umar Sheikh, Daniel Potter, Ojas Joshi, Nikhil Banerji, Jérémy Raphaël Mora-Monteros, Valentin Marguet, Elise Joy Fahy

A capsule entering a planetary atmosphere at hypersonic speeds experiences high levels of radiative heating. Furthermore, coupling between the ablation products from the surface of the vehicle and the high temperature gas can have a major effect on the hea ...

Desorption of alkali atoms from 4He nanodroplets

Marcel Drabbels, Evgeniy Loginov, Marina Langlet

The dynamics following the photoexcitation of Na and Li atoms located on the surface of helium nanodroplets has been investigated in a joint experimental and theoretical study. Photoelectron spectroscopy has revealed that excitation of the alkali atoms via ...

Investigation on the Three-Dimensional Flow Mechanisms in Annular Axial Compressor Cascades for Aero Engines with Flow Control by Aspiration on the Hub and on the Blades

Elia Colombo

The axial compressor is an essential component of aero-engines and gas turbines. This work investigates how flow control by aspiration applied to the hub and to the blades of axial compressor wheels can improve the static pressure rise by preventing detrim ...

Time-resolved x-ray diffraction study of laser-induced shock and acoustic waves in single crystalline silicon

A rod of single crystalline silicon has been subjected to high-power nanosecond laser pulses inducing ultrasonic and shock waves traveling into the bulk of the material. Stroboscopic time-resolved high-energy x-ray diffraction measurements were carried out ...

On the use of anisotropic a posteriori error estimators for the adaptative solution of 3D inviscid compressible flows

Marco Picasso

This paper describes the use of an a posteriori error estimator to control anisotropic mesh adaptation for computing inviscid compressible flows. The a posteriori error estimator and the coupling strategy with an anisotropic remesher are first introduced. ...
