The present invention relates to the field of electromagnetic rail launchers, and particularly to a rail launcher and an associated projectile-launching process including at least two longitudinal rails connected to a power supply circuit of these two rails, these rails being at least partially surrounded by superconductor elements able to generate a magnetic induction of a direction perpendicular to the plane formed by the rails and located therebetween during the flow of a current therein, launcher wherein the supply circuit includes the superconductor elements.

Electromagnetic rail launchers and associated projectile-launching method

An electrical linear actuator includes a stator assembly and a piston structure. The stator assembly includes a casing having a bore extending therethrough and about a longitudinal axis, a winding structure disposed within the bore and in contact with the casing and a plurality of stator elements connected to the winding structure and arranged circumferentially in a plurality of rows extending parallel to the longitudinal axis within the bore and disposed apart from one another to form longitudinally extending channels between adjacent ones of the rows. Each of the stator elements extends radially inwardly from the winding structure toward the longitudinal axis. The piston structure includes a shaft extending along the longitudinal axis and has an outer cylindrical surface and a plurality of piston elements arranged circumferentially in a plurality of rows extending parallel to the longitudinal axis. Each of the piston elements is connected to the outer cylindrical surface of the shaft and extends radially outwardly therefrom relative to the longitudinal axis. The piston structure is sized and adapted to be slidably received by and linearly movable within the stator assembly with each piston element being disposed within a respective one of the channels so that a gap is formed between facially opposing surfaces of the stator elements and the piston elements.
