The ACHEON concept is based on two cornerstone technologies:

  • The H.O.M.E.R. nozzle concept produces a controllable deflection of a synthetic jet, with the ability to maintain a predefined direction and to change this direction arbitrarily as a function of momentum (or velocity) of two primitive streams and of the geometric configuration of the nozzle.
    HOMER design overcomes the limitations of common Coanda effect Nozzles by the capability of producing a dynamic control of deflection angle based on a patent pending technology developed by the University of Modena and Reggio Emilia.
  • PEACE – Plasma Enhanced Actuator for Coanda Effect produces an active precision control of the Coanda adhesion to a surface by means of the BSD technology (Dielectric Barrier Discharge) which allow controlling the adhesion of the synthetic by an active control system.
    Image8PEACE being a low cost and an easily integrable system will improve the precision of the overall system controls. The PEACE technology has been preliminary studied by Universidade da Beira Interior.

The integration of HOMER nozzle with the PEACE concept can lead to disruptive potential propulsive system application shaping novel aerial vehicle architectures and opening up new possibilities based on easy to control and effective use of the Coanda effect.
ACHEON delivers relevant contributions to the challenges featuring the CleanSky and ACARE Research Agendas and Visions. In particular it opens novel frontiers for:
Developing a sustainable and green propulsion system for low noise and high efficiency.
Focusing on all-electrical aircraft vehicles, systems architectures and capabilities for “green” trajectories and improved ground operations.
