Henrik Amnell, Program Manager, Space Future Programs at GKN Aerospace Engine Systems, says: "This successful series of hot-fire tests proves the progress we've made in our sandwich wall technology. This really validates our approach to deliver high quality affordable products with high reliability and low maintenance costs. Incorporating this technology will enable us to reduce significantly production lead times and make our products more cost competitive."

J.N. Caruana, manager of demonstrators in the Future Launcher Preparatory Programme of ESA Space Transportation, says: "GKN Aero masters the technologies and modelling tools that enabled the design and manufacturing of an excellent nozzle for a hydrogen expander-cycle engine. This nozzle is working perfectly at the hot-fire test stand. It meets its demanding mass and heat pick-up requirements. This prepares for cutting-edge evolutions towards more competitiveness of our upper stage engines in Europe."
