PROJECTIL PROPULSION BY ELECTROMAGNETIC FORCE
The paper presents experiments using a laboratory model at small scale for a “coil gun” type projectile launcher. Electromagnetic acceleration of a mobile fitting by a coil (stator) travelled by an electric current is a phenomenon known in the 18th century and knows many applications of this phenomenon. Explanation refers to what passes through the stator currents and armour as well as mutual inductance variation of these. Inductance mutual values are found by means of approximation.
Keywords: electromagnetic force, projectile, ballistics parameters

Helicoidally cylindrical surfaces are used for releasing surfaces of cutting
tools the paper present aspects about experimental research of the kinematic
coupling using different loads and different contact angle between roll and
cylinder using a special developed for generation of the helical surfaces.
