Optimisation of the combustion chamber in a miniature turbine engine

<ns3:p>Miniature turbine engines, due to their small size and high trust in aircraft, are finding increasing use in autonomous power systems and for e.g. model aircraft, drones, small generators, experimental vehicles. A key challenge in their development is the optimization of the combustion chamber, which directly affects engine performance, emissions and stability. This article focuses on the question of how to design and optimize a combustion chamber for a miniature turbine engine to achieve maximum energy efficiency while maintaining compact dimensions and low emissions. The goal of the research was to develop a novel combustion chamber design that minimizes pressure losses and ensures efficient fuel combustion in a limited space. To this end, computational fluid mechanics (CFD) methods were used to simulate flow and combustion processes in various geometric configurations. As a result of the research, a combustion chamber was designed and simulations were conducted, which requires further redesign to negate the formation of unfavourable air turbulence zones. The authors' own contributions include the development of innovative combustion chamber geometry and the application of advanced optimization algorithms in CFD simulations.</ns3:p>
