“…In one of these works (Mayer et al 2007), a wind tunnel study of electro-thermal de-icing of wind turbine blades was done to demonstrate the relation among the wing surface temperature, the heating power, the ridge formed by liquid water runback and the meteorological conditions. Another study (Strehlow and Moser 2009) introduced a recent development in electrothermal heating technology that enables increased power densities on the leading edge of aircraft wings for the purpose of de-icing. In another work (Buschhorn et al 2013), the application of conductive polymer nanocomposites in making highly efficient electro-thermal IPS was tested under a range of icing conditions.…”

Various constrained problem formulations for the optimization of an electro-thermal wing anti-icing system in both running-wet and evaporative regimes are presented. The numerical simulation of the system is performed by solving the conjugate heat transfer problem between the fluid and solid domains. The optimization goal is to reduce the energy use and power demand of the anti-icing system while ensuring a safe protection. The formulations are carefully proposed from the physical and mathematical viewpoints; their performance is assessed by means of several numerical test cases to discern the most promising for each regime. The design optimization is conducted using the mesh adaptive direct search algorithm using quadratic and statistical surrogate models in the search step. The influence of the models on the convergence speed and the quality of the obtained design solutions is investigated.

“…These can be used to either prevent ice build-up (anti-icing) or to melt the base of an ice layer, thereby weakening its bonding with the wing surface until it is dislodged by the airflow 3,8,9 . Operationally, these systems are somewhat similar to the bleed air systems, but with the potential for a lower energy requirement and an improved overall mass-and volume-specific efficiencies.…”

This paper considers a novel electro-thermal system combining aligned carbon nanotubes (A-CNT) as a resistive heater and bistable laminates. The use of A-CNT heaters to actuate bistable laminates is characterized in terms of steady-state shape as a function of applied voltage to the heating element and the transient response of the laminate to heating. Snap-through from one stable state to another was successfully achieved with a linear relationshiop between laminate curvature and applied voltage up to the snap-through event. Thermal actuation of a bistable wing skin has the potential for an efficient multifunctional thermo-mechanical ice protection system (IPS); using heat to address anti-and de-icing, and secondly using thermal actuation of the bistable laminate to deform or mechanically disturb the skin to initiate debond of the ice-skin interface. Nomenclature V= applied voltage I = current P = power T = temperature
