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 :
Advanced distributed sensing using a new generation of high-fidelity fiber optics sensors
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.
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.
The SMS project is unique thanks to its strong multidisciplinary character and degree of innovation.
AeroBuzz devoted a press article to present the morphing studies carried out by the SMS project and presented in the Académie de l’Air et de l’Espace the 30th of March 2021 by Dr. Marianna Braza (Link)
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 .
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
Morphing A320 SMS Prototype of chord 0,7 m by Shape Memory Alloys (SMA) cambering the rear wing’s length of 30% of its chord, downwords and upwords at (-1.5, +1.5)% of the chord’s length at take-off and landing speeds.
Participation of the SMS project at the ILA – Innovation Leadership in Aerospace in Berlin on 25-29 April2018 in the stand of the European Commission and presentation of the project by Marianna Braza in the workshop of disruptive wing configurations on 27/04/18 invited by INEA.
Within the frame of the 7th Transport Research Arena (TRA) 2018, which took place in Vienna (Austria) from 16^th to 19^th April 2018, the SMS project has been selected to take part in one of the stands of this prestigious Exhibition. The EC stand, after a tight selection, hosts in total 24 EU-funded projects for this showcase. Only five Aviation EU projects have been selected (4 Horizon 2020 and 1 CEF/SESAR projects) and among them the SMS project. It is a high honour for the SMS project to participate in this event.
