Application and analysis of right helicoidal shells

Rynkovskaya M.J.

Abstract

Drilling machines with drilling elements as helicoid are widely used while making of drilling auger, round section testpit and so on in crust for exploration of geological structure, searching, prospecting, minerals extraction, engineering geological research. Helicoidal shells can be designed as right, inclined, open and wrong-unfolding. There are main thesises of calculation method given by V.G. Rekach for right helicoid.
