【 摘 要 】

Statistical data processing results of friction coefficient change between steel base cylinder of rotary screw propulsion unit and ice of different surface roughness are considered in the article. Experimental values of ice surface roughness complex criterion are given. It is also established that in actual operating conditions the basic factor affecting the friction coefficient change of the base cylinder on ice is represented by the processes connected with the plastic yield of the ice daylight surface irregularities. At this the adhesive component of friction force while operating on rough ice did not exceed the 20% value.
