Experimental investigation of the flow fields within novel compact compressor stages

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 the strong curvature of the flow present in such compressor stages.

Calibration of the laser metrology system on the X-ray telescope Astro-H

The Canadian ASTRO-H Metrology System (CAMS) is a laser-based device that will be designed and built in Canada and flown in space onboard the x-ray telescope, ASTRO-H. The purpose of the CAMS is to accurately measure structural deformations of the telescope structure during observations so the scientific images acquired can be enhanced by removing the errors introduced by the motion. The proposed internship focuses on the implementation of the CAMS device alongside the x-ray telescope.

Flaw growth thresholds in composites

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 using wave mode propagation based on Modal Acoustic Emission new approaches (MAE).

Strategic safety stock allocation in an assembly supply chain network

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 assembly procedures and deliver the products on time. Due to the supplier lead time variability, quality inspection related delays and other sources of uncertainty, the adherence to a production plan is almost impossible.

Techniques of aircraft engine vibration analysis

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 by the experiment (in future work), and vice versa the changes in the model parameters can be easily implemented into test rig.

Machining effects on part integrity and life of aircraft materials

Design, manufacturing and maintenance of aerospace products are cornerstones of the economy and social development of Quebec and Canada. In 2009, more than 78 000 Canadian jobs were related to the aerospace industry from which 45 % are in Quebec. These high technology jobs contribute to the quality of life and the economic growth of our province and our country. To maintain and increase these valued jobs, it is necessary to develop Canadian technologies and know-how in this field.

Shrinkage of polymer coatings on wood veneers in aircraft structures: understanding the causes of the problem and possible solution

A common problem in aircraft cabinetry is deterioration of high gloss finishes, giving an "orange-peel look", which is attributed to some kind of dimensional instability. This can be related to the veneer, the varnish, their interactions and how they evolve over time and in different environmental conditions (temperature and humidity) to which the aircraft cabinetry are exposed during their manufacturing and usage. This problem is costly to Bombardier Aerospace, who must frequently rework the cabinetry surfaces. 3M Canada is interested in providing solutions.

CFD simulation of a gas turbine combustor

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

Energy harvesting

The intern will research and develop an Energy Harvesting Device (EHD) prototype. This device will be used to power a Cargo Security Device (CSD) as well as charge the battery for the CSD. The reason for the battery is that the proposed EHD will not produce energy at all times but the CSD needs to continually be powered. The CSD is a unique tracking device used on large marine containers. The power requirements for the CSD are low but the device must function for several years with little to no human interaction.

Architecture exploration for high-integrated and low-cost avionic systems

Digital avionics systems of today are designed for the most part with embedded computers. These computers run safety-critical real-time applications such as flight management systems (FMS) and flight control systems (FCS). Even if avionics use conservative technologies, economic concerns are constantly pushing for changes. Space, weight, power and cooling (SWaP-C) considerations are gaining importance in the aviation industry. High fuel and maintenance costs encourage aircraft manufacturers to reduce the footprint of new models.
