This study aims to couple two codes, one able to perform icing simulations and another one capable to simulate the performance of an electrothermal anti-icing system in an integrated fashion.

The classical tool chain of icing simulation (aerodynamics, water catch and impact, mass and energy surface balance) is coupled to the thermal analysis through the surface substrate and the ice thickness. In the present approach, the ice protection simulation is not decoupled from the ice accretion simulation, but a single computational workflow is considered.

A fast approach to simulate advanced anti-icing systems is found in this study.

This study shows the validation of present procedure against literature data, both experimental and numerical.

The purpose of this paper is to focus on a morphing architecture, conceived to produce droop nose effect, thus preserving high lift performance and laminar flow.

A numerical approach was adopted. On the base of preliminary aerodynamic requirements, the main aspects of the actuation architecture were defined and then assessed through a genetic approach.

Two different working modalities of mentioned architecture were identified: the former implying the use of an actuator, the latter taking advantage of a tailored elastic element, able to actuate morphing under the action of aerodynamic loads, without the aid of actuators.

The research presented in this work refers to an optimisation process currently tailored on preliminary aerodynamic requirements (leading edge vertical displacement maximisation, leading edge radius increase).

The research shows the possibility of producing morphing on the leading edge zone, actuating droop nose effect on metallic (constant and pice wise thickness) and composite skins.
