FIELD: towing submersible vehicles. SUBSTANCE: submersible vehicle to be towed is positioned after stern of towship and is oriented by its stern forward in way of motion after which submersible vehicle and towship are connected by means of rope. In course of towing the submersible vehicle, speed is smoothly increased from 10 to 30 knots and dynamic lift force is created under bottom of submersible vehicle; separated flow is created around the fore extremity. Upon arrival to assigned point, submersible vehicle is separated from the towship. Proposed method is realized by means of submersible vehicle intended for tourism, recreation and for performing underwater jobs. Submersible vehicle has streamlined outer hull with hard chine bottom portion. Bilges of bottom portion have rise towards aft extremity and lines of fore extremity are engageable with bottom portion lines between bilges. EFFECT: high speed at retained good sea-going qualities in towing the vehicle in submerged position at slow speed. 3 cl, 1 dwg |
