METHOD AND DEVICE FOR DEFORMING STRUCTURE AND ITS SURROUNDING MEDIUM Russian patent published in 1999 - IPC

FIELD: conversion of electrical energy to mechanical work by means of electric pulses for exciting shock, acoustic, hydraulic, and geophysical waves. SUBSTANCE: structure is exposed to electromagnetic vortex field growing towards field-strength axis of vortex. Time of electromagnetic field growth to its maximum is set from equation t_m ≤ kd²γ, where k is coefficient of proportionality; d is thickness of current-conducting structure along field-strength axis of vortex; γ is electric conductivity of structure material. Method is implemented by coils wound of T-shaped conductor turns. Conductors are wound on coil so that slots are filled with projections. Total thickness of conductors along coil axis is found from equation , where D is total thickness of conductors along coil axis; γ is electric conductivity of structure material. EFFECT: improved economic efficiency. 14 cl, 7 dwg, 8 ex
