Abstract

El presente invento se refiere a un des congelador destinado a estar montado en el borde de ataque de una pala de hélice, en el cual el elemento de calentamiento situado en el des congelador presenta un circuito continuo en forma de ziz-zag desde la extremidad interna del des congelador que está situada muy cerca de la extremidad de vástago de la hélice hasta la extremidad externa o punta del des congelador, teniendo el elemento de calentamiento una densidad de potencia progresiva que se extiende a partir de la extremidad interna hasta la extremidad externa, estando la mayor densidad de energía en la extremidad interna. Este calentamiento progresivo puede presentar una forma escalonada con variaciones como se indica más adelante.
