DRIVING DEVICE FOR APPLYING A MAGNETIC PULSE TO A MECHANICAL ASSEMBLY AND AIRCRAFT CARRYING EJECTION DEVICE IMPLEMENTING SAME

摘要

The device of the invention comprises an electromagnetic coil (3) in which a piston (6) is capable of sliding and has at least one portion made of a material having a paramagnetic susceptibility and in contact with said mechanical member when said driving device (1) is at rest. An electric supply means is provided for storing electric energy and for abruptly releasing said electric energy into the coil, thus applying a movement pulse with high magnetic energy to said mechanical member. According to the invention, the piston (1) comprises a stack (9) of blocks (11, 12) alternatively made of the material having a paramagnetic susceptibility and of an insulating material. The electric supply means is provided so as to apply the energy to the coil in the form of a succession of electric pulses occurring together with the movement of said piston (6).
