Syensqo signs Long-Term Supplier Deal with Vertical Aerospace, to Support Industrialisation Plan for Its VX4 Aircraft
Vertical Aerospace has announced a new long-term supplier partnership with Syensqo, where the company’s advanced composite and adhesive materials will be integrated across the entire structure of Vertical’s VX4 eVTOL aircraft.
Syensqo has already supplied materials which were used in Vertical’s prototype programme, providing the lightweight, strength, structural efficiency and durability required for high-cycle operations of electric vertical flight. This will ensure the VX4 can withstand repeated take-offs and landings, while maintaining safety and performance at scale.
Stuart Simpson, CEO, Vertical Aerospace, said: “We are bringing the VX4 to market alongside leading global partners, and deepening our successful partnership with Syensqo as our advanced-materials supplier is a vital step in that journey.
“Their decades of expertise in lightweight, high-performance composites — combined with our shared commitment to safety and certification — will help us deliver a resilient, agile aircraft as we progress toward commercial operations.”
This extension of Vertical’s partnership with Syensqo comes as Vertical continues to formalise the core supply chain for its certification aircraft, alongside Honeywell, Aciturri and other global partners.
Syensqo brings extensive aerospace experience, supplying advanced materials to many of the world’s leading aircraft manufacturers and defence companies. Vertical says this experience makes Syensqo an ideal partner as the company advances toward both civil and defence applications of its aircraft platform.
Rodrigo Elizondo, President Syensqo Composite Materials, said: “We are honored to deepen our collaboration with Vertical. Our advanced composite and adhesive technologies are designed to push the boundaries of lightweighting and performance, supporting the VX4’s journey toward safer, cleaner and more efficient air mobility.
“As Vertical moves into certification and industrialisation, we look forward to bringing our scientific expertise and strong customer partnership to support the VX4’s successful entry into full-scale production.”
The VX4’s airframe itself will be manufactured by Aciturri, a leading global aerostructures supplier which will support Vertical’s transition into full commercial production.
Vertical plans to unveil its new aircraft design this Wednesday (December 10th) in Canary Wharf, London, showcasing the VX4’s industry-leading design, passenger and luggage capacity, and global certification-ready architecture.
eVTOL Insights has kindly been invited to the unveiling, so please keep an eye on our website and social media channels later this week for pictures and additional reaction.
