The Smart Morphing & Sensing (SMS) project is a multi-disciplinary upstream project that employs intelligent electro-active actuators that will modify the lifting structure of an aircraft and to obtain the optimum shape with respect to the aerodynamic performance (high lift & low drag). This will be accomplished using a new generation of fiber optics based sensors allowing distributed pressure measurements and in-situ real-time optimisation of the aerodynamic characteristics. This will allow to attenuation of flow separation and nuisance instabilities such as aileron flutter and also to reduce trailing-edge noise and other vibration sources in flight, coming from interactions between wing and fuselage and engine or from critical meteorological phenomena as gusts, having major impact on safety. The SMS project associates the following methods that will be coupled in a multi-disciplinary environment :

  1. Advanced integrated aeroelastic design using High-Fidelity CFDSM (Computational Fluid Dynamics-Structural Mechanics)
  2. Advanced distributed sensing using a new generation of high-fidelity fiber optics sensors
  3. Advanced experimental techniques to provide data together with the high-fidelity simulations for the iterative feedback of the controller design to be used for the optimisation of the morphing flap of an A320 type wing. These experimental techniques will also be used as a basis for the validation of both the novel actuation and sensing systems via wind tunnel tests at subsonic (take-off and landing) and transonic (cruise) speeds.
  4. Controller Design by appropriate Flight Control Commands (FCC), to actuate the electro-active materials properties in order to enable a real-time in-situ optimisation of the final prototypes in reduced scale and large scale.
  5. The SMS project is unique thanks to its strong multidisciplinary character and degree of innovation.

The 30th month meeting

The 30th month SMS meeting was organized by our partner : Politecnico di Milano (POLIMI) in 27 – 29 November 2019.

Experimental tests will be carried out for the Large-Scale prototype wing-flap in different configurations : Clean, take-off and landing at a subsonic speed.

The European Researchers’ Night (La Nuit européenne des Chercheurs)-Toulouse

The SMS project has participated in the stand of INPT/CNRS/IMFT/LAPLACE Laboratories at the European Researchers’ Night (Nuit Européenne des Chercheurs) on 27th September 2019 at the “Quai des Savoirs”, in Toulouse, France. In the devotes stand were presented our work and shown to a large people’s audience concerning the bio-inspired electroactive morphing of wings .

Prace (Partnership for Advanced Computing in Europe) allocation project

The SMS project’s numerical simulations received from the PRACE allocation project N°2017174208 of the European Commission 15 million CPU hours on the CEA – TGCC HPC Infrastructure from April 2018 until April 2019. Part of the SMS simulations are carried out in the French Supercomputing Centres CINES, IDRIS and CALMIP
