Delta improves fleet efficiency with VCT Finlets across the 737NG fleet | News
VCT today announced that Delta Air Lines will install a Vortex Control Technologies (VCT) finlet modification package on its Boeing 737-800 and 737-900ER fleet, bringing the expansion to 240 aircraft once installation is complete. The decision follows extensive technical cooperation and in-service review between the two companies, including analysis of test flight data, operational trends and technical assessment of aerodynamic performance.
HOW FINLETS WORK
Finlets are aerodynamic devices installed on the rear fuselage of an aircraft that reshape airflow, reduce drag and improve fuel efficiency. All aircraft generate vortices during flight, especially at the wing tips and rear fuselage. VCT’s Finlets reduce flow separation and improve pressure distribution along the rear fuselage, resulting in lower fuel consumption and CO2 emissions.
“Equipping these Boeing 737-800 and 737-900ER fleets with Finlets is a significant milestone for VCT. We are proud to offer a practical technology that helps airlines improve fuel efficiency, reduce CO2 emissions and improve operating economics,” said Gil Morgan, Chief Executive Officer of Vortex Control Technologies.
BUILDING ON PROVEN FLEET MODIFICATION WORK
The finlet implementation builds on Delta’s ongoing approach to fleet adjustments and was cemented with safety and strategy in mind, driven by a rigorous review process. The assessment included flight test validation, operational trend analysis and technical assessment of aerodynamic performance using computational fluid dynamics (CFD) analysis of Delta’s 737NG aircraft.
Delta’s decision to equip its Boeing 737-800 and 737-900ER fleet with Finlets reflects the airline’s continued focus on reducing fuel consumption, lowering emissions and improving operational efficiency through practical, data-driven solutions.
SUSTAINABILITY AS AN OPERATIONAL COMMITMENT
With approximately 90% of Delta’s carbon emissions coming from jet fuel consumption, initiatives like Finlets play an important role in improving fleet efficiency while supporting the airline’s broader sustainability goals.
“Delta seeks partners and innovations that improve performance, reduce environmental impact and drive long-term operational benefits,” said Amelia DeLuca, Delta’s Chief Sustainability Officer. “We appreciate the strong partnership with VCT during the evaluation process and look forward to this implementation to further support our ongoing fleet efficiency initiatives.”
By moving forward with this sustainability program, Delta continues to advance its environmental goals, driven by the dedication and hard work of the teams that made the assessment possible.
