Sustainable Aviation Gasoline – RTX’s Pratt & Whitney collaborates with FAA to review non-CO2 emissions beneath FAA ASCENT program.
Pratt & Whitney, an RTX (NYSE: RTX) enterprise and the Federal Aviation Administration (FAA) will work along with Missouri College of Science and Know-how (Missouri S&T), Aerodyne Analysis, Inc., and the Environmental Safety Company (EPA) to review non- CO2 aviation emissions, to assist perceive and cut back the environmental affect of these emissions.
As a part of the FAA’s ASCENT program, the undertaking will measure emissions from a Pratt & Whitney GTF™ engine combustor rig check stand utilizing standard Jet A and 100% sustainable aviation gas (SAF).
Sean Bradshaw, senior technical fellow of sustainable propulsion at Pratt & Whitney mentioned:
🔥 What about we co-host a webinar? Let’s educate, captivate, and convert the biofuels economic system!

Because the aviation {industry} targets a purpose of net-zero CO2 emissions by 2050, we proceed to pay shut consideration to addressing the environmental affect of different emissions, together with cruise non-volatile particulate matter and NOx.
“Combustor rig assessments with 100% SAF present a managed surroundings for producing invaluable baseline knowledge, which can assist future research utilizing full scale engines on-wing at floor and flight check circumstances.”
The undertaking will evaluate emissions from Jet A kerosene and SAF comprised of 100% Hydroprocessed Esters and Fatty Acids Artificial Paraffinic Kerosene (HEFA-SPK), a biofuel derived from vegetable oils and animal fat; the gas is provided by World Power.
Dr. Philip Whitefield of Missouri College of Science and Know-how mentioned:
By bringing collectively experience from {industry}, authorities, and academia, this undertaking represents an essential step in the direction of understanding and lowering the environmental impacts of aviation, together with these arising from non-CO2 emissions.
“SAF containing low sulfur and fragrant hydrocarbon concentrations might contribute to lowered sulfur dioxide and non-volatile particulate emissions, that are related to contrail formation and the affect to international warming.”
The rig assessments will happen at Pratt & Whitney’s facility in Middletown, Conn., utilizing a sophisticated Wealthy-Quench-Lean (RQL) combustor. The rig permits testing of the complete vary of combustor working circumstances, together with at take-off, floor, and cruise altitudes, to assist perceive the environmental and emissions advantages of utilizing SAF.
Pratt & Whitney, the FAA, Missouri S&T, Aerodyne Analysis, and the EPA will collaborate on check design, execution, and emissions knowledge evaluation.
