System identification and control of fixed wing unmanned aerial vehicles

MicroPilot, a company located in Manitoba, is specialized in design and manufacturing of autopilot systems for unmanned aerial vehicles (UAVs). The company’s interest is to develop accurate simulation models of various UAVs, upon which the autopilot systems are tuned and verified first. The goal of this project is to evaluate and improve the model structure adopted, and develop appropriate tools for extracting accurate models to be used by the simulation.

Advanced text clustering algorithm for aircraft applications

CaseBank provides a service called ChronicX™ to the airline industry for the purpose of detecting and managing repeat defects, i.e. faults that have eluded resolution repeatedly. Each night, airlines upload their raw maintenance records to the CaseBank server. ChronicX applies text mining methods to eliminate irrelevant records, and search for defects that are repeat occurrences of defects previously reported. These are assembled into clusters, each of which is called a ‘chronic’. ChronicX performs reasonably well, but it has limitations that we believe can be improved.

Shot peening for fatigue life improvement and forming of aerospace structures

The principle objective of this collaborative project is to develop in collaboration with the industrial partners novel methodologies for characterizing the shot peening and peen forming processes. One part of the program is devoted to establish analytical and numerical models for the prediction of the shot peening and peen forming processes. Experimental campaigns are planned in order to qualify the effect of the shot peening parameters on the peening results as well as to validate the developed models.

Feasibility study of dual input clamp undir DC-DC converter for 737 SPU replacement

The main objective of this project is to a) investigate feasibility and suitability of a new proposed DC-DC converter based on a novel “Dual Input Clamp Unidir DC-DC Converter”, and b) validate and quantify its projected benefits including reduced parts count, higher efficiency, lighter weight and more reliable as compared to existing commercial products. Cost-effective, efficient, reliable and high-speed gate drivers, clamp circuits, and HF isolation transformer suitable for operation at switching frequencies of 100 kHz need to be developed for the proposed DC-DC converter.

Energy efficient integrated design of flight management systems and autopilots

The amount of emissions to the atmosphere is currently an important environmental concern as policy makers and Heads of State are starting to demonstrate a strong interest in energy efficient transportation, in particular energy efficient aircraft. However, current autopilot technology will often not take into account the energy used to perform a given maneuver which can lead to potentially larger fuel consumption and larger atmospheric emissions than what is strictly necessary. The task of energy optimization is typically left to a flight management system (FMS).

Interactive visualization of design stories for parametric design systems

This project involves the development and implementation of a visualization, analysis and exploration prototype for a parametric CAD tool. The prototype focuses on the design process; that is, the collection of actions taken by designers as they develop solutions. The visualization will allow designers to analyze, understand and make better decisions based on single actions and/or patterns across time. Designers using the prototype will be able to explore new design solutions derived from this knowledge using the visualization itself.

A camera stabilization gimbal system for a small unmanned aerial vehicle

Remote industrial installations and other areas requiring surveillance can be monitored effectively by an Unmanned Aerial Vehicle (UAV). UAVs are remotely operated, with on-board camera systems. Fixed camera systems are of limited use, because the field of view is limited to the direction in which the aircraft is flying, which continually changes as the aircraft moves while flying. A gimbal system can reduce this effect by compensating for changes in aircraft orientation, which fixes the direction of the camera.

Extended product lifecycle management through social computing technologies

This study will present a method for improving informal information flow during product development process in aerospace industries using social computing tools. In actual engineering information exchange, the knowledge is transmitted informally around the coffee machine or through a formal document in the process. In contrast, the author presents a method for proactive participation of users during design activities. The framework, a perspective for integrating community of practices in product development enhances knowledge sharing and retention.

Development of model for high temperature composite materials used in aerospace

The use of composite materials for high temperature aerospace applications requires new studies in order to better understand the behaviour of these novel materials, and to generate appropriate design tools. The main goals of this project are to develop a set of numerical tools that will be used to predict the fatigue behaviour of advanced high temperature composite materials. The first step will be to complete the development of the tools. Then, the tools will be implemented into existing software currently used by the industry partner.

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.
