Keywords: gas turbine, aviation, reliability

Demands for small gas turbine technologies from the market place continue to evolve; for combustion systems this has resulted in advancements of design and manufacturing processes and tools to reduce design leadtimes and improve quality of first designs. Market feedback analysis and controlled engine/rig tests have been successfully used to validate new design processes and tools. New combustor technologies are addressing need for low emissions and high reliability as well as low cost manufacturing methods. Status of small engine combustor technology and innovation to meet current and future market challenges are discussed, along with developments in numerical tools and manufacturing methods. Results of association with Canadian universities and national laboratories are also highlighted.
