Cold Spray Additive Manufacturing of a Ti-Zr-Ni shape memory alloy for future large deployable aerospace components.

Shape Memory Alloys (SMA) are smart materials capable of recovering large inelastic strains. SMA are therefore excellent candidates for applications where deformation needs to be controlled remotely. One of the main challenges holding back a wider acceptance of SMA is their poor workability leading to high tool wear when manufactured by machining. Additive Manufacturing, also […]

Study of delta Scuti stars with probable magnetic field

Four cycles of observations with the space telescope TESS have provided high-quality photometric data and have led to discovery of a group of delta Scuti stars that show pulsations at high frequencies (nu> 40 c/d) which are similar to the pulsations of roAp stars. Recent discovery of magnetic field in delta Scuti star HD41641 suggests […]

ML enhanced magnetic noise modeling for quantum magnetometry

Magnetic field sensing is intrinsically sensitive to its environment. In this project, we are developing compensation tools to mitigate against different types of magnetic noise to enhance the accuracy of a quantum magnetometer and of a platform including multiple magnetometers. Data will be collected at various magnetic characterization facilities to inform a ML based correction […]

Characterization and improvement of a robotized material removal process

As part of its services, GE Aviation provides rapid repairs for engines, including borescope inspection/blending, line replaceable unit (LRU), fan module, gearbox repair/removal, and many additional workscopes. One of this repair service centers around airfoils. During flight, the compressor and turbine airfoils get damaged by dust and other contaminants. During the overhaul process, the airfoils […]

Identification expérimentale et sans contact du mistuning de blisks par excitation acoustique

Les turbines que l’on retrouve notamment dans les turboréacteurs sont soumises à de très grandes charges, dont de grandes vibrations. De plus, ces vibrations peuvent être amplifiées si de trop grandes imperfections sont présentes pour une turbine donnée. Il faut donc bien détecter ces imperfections pour déterminer si une turbine est sécuritaire avant de l’inclure […]

Electric Machine for Landing Phase Kinetic Energy Recovery of Commercial Aircraft

The pollution from aircraft is expected to be seven to ten times higher in 2050 compared to 1990 level. To address the issue, a kinetic energy recovery system fitted onboard commercial aircraft is proposed. The system is widely used in automotive industry but has never been proposed for aerospace applications. Electric machines are a limiting […]

Satellite Technologies for Space Situational Awareness (SSA)

Today, small satellites are launched in large constellations like Starlink and Globalstar for space-based services, such as communications and weather monitoring. This rapid growth in space objects has become a real threat for space operation. In response to this issue of the growing population of space objects, Magellan is developing technologies to provide extensive and […]

Blade Fragmentation modeling in hard-wall containment systems

According to the existing airworthiness standards, aircraft turbofan engine certification must demonstrate its ability to contain a fan blade should the blade accidentally separate under critical operating conditions. P&WC has established a full engine computational analysis process. In the continuing evolution of this modelling process, several areas requiring improvement have been identified as critical. One […]

The Three-Body Problem, and the Great Inequality of Jupiter and Saturn

We propose to produce a self-contained analysis and reduction of the equations of motion of the much-studied three body problem, making application to the Great Inequality (GI) of Jupiter and Saturn. The GI is a result of the mutual gravitational attraction between these two planets. Their orbits are very nearly in resonance (integer ratio of […]
