Press release #1 – ACHEON: thrust vectoring propulsion for future Green Aeronautics


Despite the current technological maturity reached by the transport industry, including aeronautics, there are still opportunities for opening-up new frontiers through breakthrough research which could give impetus to radical new innovation in future air transport.

ACHEON is a new project funded by EU FP7 Transport (Level 0) and aimed at developing breakthrough propulsion technology for green air transport. ACHEON explores the feasibility of a novel propulsive system for aircraft which is expected to overcome the main limitations of traditional systems related to typical jet deflection systems.

The main objective is to produce the trust vectoring solely by fluid-dynamic effecst without any moving parts. In particular the project aims:

  1. to define:

  • the system, its control methodology and equations identifying the geometric and physical parameters, their possible limits and the fields of applications;

  • system design methods applicable to different sizes and architectures;

  1. to explore the feasibility in the following fields:

  • traditional aerial vehicle architectures;

  • innovative aerial vehicle designs such as distributed propulsion;

  • innovative aircraft optimized for thrust vectoring

The ACHEON thrust system involves three different physical effects:

  1. High speed jet mixing effects;

  2. Coanda effect of adhesion of a high speed jet to a convex surface;

  3. Coanda effect control by Electrostatic fields.

INSIDE ACHEON

The ACHOEN concept is based on two core 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 fundamental air streams and 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 BSD technology (Dielectric Barrier Discharge) which allows control of the adhesion of the synthetic by an active control system. PEACE 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 University of Beira Interior.

The integration of HOMER nozzle with the PEACE concept can lead to a 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 featured in the CleanSky and ACARE research agendas and vision. 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 operation.

EXPLOITATION DIRECTIONS

Further possibilities of technology transfer are expected in different industrial sectors:

  • technology: material deposition, sandblasting, painting, etc.;

  • appliances: washers, dryers, dishwashers, etc.;

  • acclimatization: environmental air distribution;

  • industrial plants: air distribution, car washers, street sweeping and washing, cyclone filtering, etc.;

  • agriculture: sprinklers, sprayers, etc.

THE CONSORTIUM

ACHEON is run by a consortium made of 6 organisations: 4 Universities, 1 Research & Tech Transfer Organization and 1 Research intensive SME (Nimbus S.r.l) from 4 European Countries (IT, PT, UK, BE). The Consortium envisages the trialling of the novel propulsive system within the MAAT project that is developing a novel multibody advanced airship for aerial transport.

The project kick-off meeting will take place at Reggio Emilia (IT) next 10-11 January 2013. A public event will be co-located to present to the industrial community the novel concept and its transferability potential to other sectors and applications beyond the aeronautics.
