Automated Visual Inspection, Sentencing & Dressing

Within the aerospace sector, aftermarket services account for over 50% of revenue generated by aero engine manufacturers. Central to this is the ability to inspect and repair high unit cost components. Many processes are manual but given the ever-increasing quality, cost and delivery requirements, and the safety critical nature of these rotating parts, there is a strong drive towards process automation.

Optimization of residual stress of Ti-6Al-4V for Liquid Impingement Erosion Mitigation

The recent work done in collaboration with the group of prof. Bocher on water erosion mechanisms at ETS showed that the erosion in titanium Ti64 alloy compressor blades is based on crack initiation and propagation. These phenomena are dependent on material microstructure, as well as on the stress level. Ti64 alloys can have various types of microstructures and textures. Therefore, a better understanding of the impact of the microstructure and texture is required in order to define the optimum material condition.

Coalescence Free Surfaces

Water injection in the industrial gas turbines is frequently used to improve the turbine performance during hot days. Injected water evaporates in the compressor section providing effective cooling leading to increased gas density and improved performance. Water injection technology poses several technological challenges. The injection system needs to be optimized to provide a uniform droplet size distribution across the inlet cross section.

Experimental and Finite Element Analysis of Electron Beam Weld in Inconel-713LC Turbine Blades

Electron beam welding of shroud in Inconel-713LC blades are often associated with cracking. This leads to a high scrap rate for manufacturing of blades used in the gas turbine engines. In this study, in order to understand the root cause of the cracks, a comprehensive experimental and finite element analysis will be carried out to correlate the process variables and response of material to electron beam welding. In that way, electron beam welding process parameters will be optimized to suppress cracking.

Exploration of Novel Fuels for Gas Turbine Applications

The internship for each student will be under the supervision of Gilles Bourque PhD, the Combustion Research and Technology Team Leader. Mr Bourque has been working for the past 12 years at RR Canada of which 10 in the Combustion department. The student will be an integral part of his team and as such will also interact with key members of the team on a daily basis.
