Abstract
This paper aims at presenting the results of the CleanSky 2 European project IMPACT (GA no. 885052), granted under the Large Passenger Aircraft Integrated Technology Demonstrator (LPA-ITD), aiming at optimizing the rear-end design for the next generation Short and Medium Range (SMR) A320-like aircraft. Specifically, the project has investigated a Forward Swept Horizontal Tail Plane (FSHTP) enhanced with a Leading-Edge eXtension (LeX) device. The activities have focused on the optimisation of the horizontal stabilizer, accounting for the coupled aerodynamic, aeroelastic and, for the first time, icing behaviour. The optimal solution provides significantly better lift performance of the tailplane (i.e. up to 12.4% increase in CL), limiting the drag penalty to below 1.0% in cruise condition (i.e. between 0 and 2 degrees of Angle of Attack).
