PWC effectue des tests sur les compresseurs lors du développement de ses moteurs afin de mieux connaître les niveaux vibratoires des ailettes en fonctionnement. Le but de ce projet de recherche est de développer une méthode numérique basée sur des considérations aéroélastiques et capable de prédire efficacement ces niveaux vibratoire afin de limiter la voie […]

The future of aerospace technology relies on us investing in lighter, more fuel-efficient materials that can operate at hotter temperature with greater corrosion resistance. One such alloy that has the potential to meet these needs is the new aluminum alloy A205. In this work we aim to develop a hard anodising process for the A205 […]

Additive manufacturing (AM), 3D printing, offers flexibility in manufacturing and can process a wide range of materials. In this project, polymers and composites are investigated to increase mechanical performance, and to reduce weight, cost, and lead time of candidate parts. Pratt & Whitney Canada (P&WC) can greatly benefit from AM processes in aircraft engine components. […]

Vibration of aircraft engine is the major contribution to the structure vibration in an aircraft. To reduce the cabin noise and improve the comfortability for air passenger, research design and analysis are desired in the engine technology. A critical component in eliminating the vibration in an aero engine is the squeeze film damper (SFD). Current […]

This project is designed to develop an inspection and evaluation method for structural brazed joints using ultrasounds. Priorities for such an application include the ability to ensure the integrity of brazed assemblies and detect internal flaws and vulnerabilities in the microstructure. Developing a reliable inspection method is essential for the use of structural brazed joints […]

This project consists in implementing into a commercially available finite element package a nonlinearly viscoelastic constitutive theory that represents the mechanical behavior of a polymer. The first step will be devoted to learn the software used by the industrial partners. Then, the constitutive theory will be implemented into the software and intensively tested. Finally, the […]

The proposed project aims to reduce emissions and fuel consumption in the next generation of aircraft engines.  Better aerodynamics, higher efficiency and reduced weight are possible by improving the performance of the core engine components (ie. Compressor, combustor and turbine).  Advances in the understanding of the flow field are needed to achieve this goal.  Velocity […]

The work to be conducted in this internship consists of the transient numerical modeling of a combustion device using commercial computational fluid dynamics (CFD) codes. Validation of the various sub-models is required and once the final model is complete various design changes can be researched. The model will allow for variations in geometry, spray and […]

The Master’s student will conduct the investigation of the state-of-the-art of the engine mount-damper-aircraft structure technology to reduce the aircraft structural vibration. He/she will establish the framework for the modeling, based on the test and experiment procedures that are provided by P&WC. The modeling will be planned so that the model results can be verified […]

A new generation of composites-intensive aircraft designs promises to dramatically accelerate the growth of a market currently valued at more than $7 billion (USD). The objective of this research program is to propose experimental and modeling methodologies to determine endurance limit for damage onset in composite based on fracture mechanics and fatigue crack initiation monitoring […]

The supply chain structure of an engine assembly line consists of several complex flows and processes to satisfy the requirements for on time delivery of these products. The difficulty in managing such systems is due to the fact that more than 1000 parts should be available on time in a synchronized manner to start the […]

The aim of the internship is to conduct airflow velocity and turbulence measurements within a novel, compact aircraft engine compressor stage, using a non-intrusive technique, and then compare the results with those obtained from numerical (computational fluid dynamics, CFD) models, thereby developing an understanding as to how the different models deal with turbulence and with […]
