His expertise has primarily been focused on enhancing the efficiency and emission control of combustion systems used in turbine engines.

Latest Patents

Fischer's latest patents reflect his commitment to innovation in combustion technology. One notable patent is a comprehensive combustion system for gas turbine engines. This system integrates a Catalyst (CAT) combustion sub-system and a Dry-Low-Emissions (DLE) combustion sub-system. It generates combustion products under a lean premixed fuel/air condition, thus promoting high efficiency while minimizing emissions of nitrogen oxides and carbon monoxide. The system demonstrates versatility by operating initially with the DLE combustion process under low load conditions and switching to the CAT sub-system during high load scenarios.

Another of his significant inventions is the combustor/turbine successive dual cooling arrangement. This innovative design features a one-piece hot combustor wall paired with front and rear cold combustor walls. By using pressurized cooling air that impinges on the hot combustor wall, this arrangement reduces the quantity of air required for cooling, thereby maximizing efficiency. The cooling air is directed to the turbine section to effectively control temperatures without negatively impacting combustion emissions.
