Abstract: A system is disclosed for deicing the skin surface of aircraft and comprises a power supply unit to which are connected an electrical power accumulator and a program switch. Low inertia converters such as magnetostrictive vibrators are provided in close proximity to the skin surface and are fed from the power supply unit via key switches each having one input connected to the electrical power accumulator while its second input is connected to the program selector switch such that the switch will produce successive single or bundles of electrical pulses separated by pauses at the converters.
