Abstract
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 pules separated by pauses at the converters.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
An electric system of a device for deicing the surface of thin-walled structures, such as the skin surface of aircraft, comprising: a power supply unit; an electric power accumulator connected to said power supply unit; a program selector switch likewise connected to said power supply unit; low-inertia converters adapted for converting electric pulses into mechanical pulses, said converters being provided in close proximity to said skin surface; key switches, one before each of said converters; each key switch being electrically connected by its output to said converter, whereas one of the inputs of said key switch is connected to said electric power accumulator, while the second input of said key switch is connected to said program selector switch adApted to switch in the respective key switch to said electric power accumulator to produce successive single electrical pulses separated by pauses.
