Há a necessidade de prevenir formação de gelo nas asas e nos estabilizadores de aeronaves, pois as formas de gelo podem causar a degradação do desempenho aerodinâmico, o aumento de peso, bem como dificuldades de controle e manobra que, em casos

No presente trabalho foi implementado um modelo matemático para simular o sistema antigelo eletrotérmico de um aerofólio. Por meio do programa ONERA2D simulou-se o escoamento potencial completo com velocidade 44,7 m/s (100 mph) e 89,4 m/s (200 mph

We present the implementation and results of an airfoil electrothermal anti-ice mathematical model. From flowfield and supercooled water droplet impingement data up to electrical power density distribution, the numerical code is able to predict airfo

A mathematical model was developed to both describe an airfoil electrothermal anti-ice system operation and enable prediction of its main parameters. A reference case was chosen to define the mathematical model and support the results validation. The

Various classic icing codes have been developed and used by the aircraft manufacturers to predict the ice shapes evolution in non-protected airfoil surfaces. These codes apply boundary layer integral analysis, based on sand grain roughness, to estima

Under icing conditions, it is necessary to heat and control the temperature of the airfoil surface at leading edge region to prevent ice formation. The thermal anti-ice system balances mainly the evaporative cooling effects, which are caused by the c
