Bombardier, a leading manufacturer of both planes and trains in the world, has become a major contributor to Canadaâs economy. Facing todayâs competitive market, Bombardier aims to retain existing customers and attract new customers through operational transformation, which focuses on continuous improvement in its internal operational efficiency.
The application encompasses two projects that center around continuous process improvement.
Business aircraft seats are typically designed to provide maximum comfort to the occupant, while adhering to strict certification requirements. This tends to result in the designed seat becoming heavy and costly due to conservative tradeoff analysis, and a dependence upon legacy design techniques. With the advent of more powerful computer aided design techniques it is possible to design a seat that meets both the comfort requirements of the occupant, and strict regulatory requirements.
Over the past 10 years, the commercial aircraft market has seen almost a tripling in the number of players while business aircraft manufacturers around the world have filled or narrowed segment gaps with clean sheet or major derivative products. In this new reality, product differentiation is becoming extremely challenging and gaining a distinct advantage in aircraft performance, through weight in particular, is paramount. Aircrafts are composed of highly complex systems and their design puts great strain on engineers creativity.
Among the different sub-systems in an aircraft, the environmental control system is the one responsible for the control of temperature, pressure and humidity in the cabin and is crucial to passenger comfort. This system has around 40 components including heat exchangers, compressors, and turbines. Recirculation at different levels complexifies the modeling and simulation of such a system. The importance of modeling this system lies in the fact that one has to verify that the cabin comfort is assured under various operating conditions.
Airlines take the extra effort required to figure out what is the best route that their aircrafts should take so as to minimize additional costs from non-revenue flights or idle time. One way to di this is to first generate large numbers of feasible routes and then assign flights to a subset of them so as to cover all flight legs. It is clear that the quality of the resulting solution depends highly on both the number of routes we generate anf also the diversity among the routes.
The effective planning of resources when scheduling maintenance tasks and repair jobs is an enormous challenge, especially for heavy industries such as aerospace and transportation manufacturers. In such industries, because of the product complexity and variety, not to mention continuous technological improvements, a broad range of maintenance tasks and high-performance services should be done over the course of a year to guarantee the safety and reliability of the products.
Bombardier Aerospace, Bell Helicopter Textron Canada Limited and Pratt & Whitney Canada have all initiated projects on Additive Manufacturing processes. Although applications are different, all companies are facing the same challenges including the lack of a mature certification path and a mature Canadian supply chain. In order to accelerate the maturation of this technology, we are proposing the first Canadian industryled R&D program on additive manufacturing (AM).
The numerical simulation of turbulent flows is an important component in the process of the aircraft aerodynamic design and development. The computational Fluid Dynamics (CFD) solvers used for predicting the aerodynamic forces and moments should be capable of accurately predicting turbulence effects. Such accuracy is crucial to efficiently design aircrafts with improved quality and performance.
The proposed research project concerns the development of optimization tools and sizing methodologies used to assess optimal structural airframe configurations and aerodynamic lines for given business cases. A PDF intern will be in charge of proposing improved optimization strategies, mainly related to composite material, and of adding specific capabilities inside the internally developed sizing tool (LibStress) with the aim to increase the reliability and accuracy of the optimization models.
The principles of lean engineering design are well documented for the automotive industry – where they have served to revolutionize the efficiencies of North American manufacturing operations. Lean engineering has subsequently been transferred into other sectors – where it continues to generate impressive results. The aerospace industry is faced with demands for efficiency of operations, and the throughput of existing plant operations are being challenged to meet increased needs for aircraft to support the growth of emerging markets, and the need for more fuel efficient aircraft.
