Pratt & Whitney and FAA partner on non-CO2 aviation emissions

RTX's Pratt & Whitney and the Federal Aviation Administration (FAA) will collaborate, along with the Missouri University of Science and Technology Aerodyne Research, and the Environmental Protection Agency (EPA), to study non-CO2 aviation emissions. The study will evaluate and measure the environmental impact of those emissions. ""As the aviation industry targets a goal of net-zero CO₂ emissions by 2050, we continue to pay close attention to addressing the environmental impact of other emissions,"" said Pratt & Whitney senior technician fellow of sustainable propulsion Sean Bradshaw. The project will conduct the measurements with the emissions from a Pratt & Whitney GTF engine combustor rig test stand. It will use conventional Jet A and compare against 100% sustainable aviation fuel (SAF) as part of the tests. Bradshaw added: ""Combustor rig tests with 100% SAF provide a controlled environment for generating valuable baseline data, which will support future studies using full scale engines on-wing at ground and flight test conditions."" Missouri University of Science and Technology Philip Whitefield said: ""By bringing together expertise from industry, government, and academia, this project represents an important step towards understanding and reducing the environmental impacts of aviation, including those arising from non-CO₂ emissions.” The rig tests will take place at Pratt & Whitney's facility in Middletown, Connecticut, using an advanced rich-quench-lean combustor.
