    Naval Group and Centrale Nantes print the world's first hollow propeller blade

    Naval Group and Centrale Nantes have printed the first demonstrator of hollow propeller blades by metal additive manufacturing as part of the European H2020 project, RAMSSES. Funded by the European Commission, this collaborative programme aims to reduce the environmental impact of ships. Naval Group and Centrale Nantes are taking the lead within this project on the production of innovative propeller demonstrators to improve the operational capabilities of ships.

    In order to improve vessel propulsion, Naval Group and Centrale Nantes are using additive manufacturing to design large parts (propellers of 6 metres in diameter), which could not be produced thus far using traditional manufacturing technologies. Implementing the WAAM (Wire Arc for Additive Manufacturing) process, allows for printing of large parts and paves the way for the production of propellers with more complex geometry.

    Substantial industria gains
    The one-third scale hollow blade demonstrator, representative of a container ship propeller, was printed in stainless steel in less than one hundred hours, weighing in at about 300 kg. The teams’ sheer technical prowess means that weight gains of over 40% will be achievable compared to conventional processes.

    Significant operational gains
    Sirehna, a Centrale Nantes spin-off and subsidiary of Naval Group, is piloting the blade design in order to improve propeller energy efficiency and reduce their environmental impact. Sirehna’s work has led to an overall optimization of blades in terms of efficiency and endurance, but also a significant reduction in radiated noise and vibrations.
