![]() The only thing worth considering is that the bow dive planes placed on the sail won’t help us during the dive maneuver, in contrast to the ones placed on the bow. Both mounting types have their cons and pros, most of the differences are rather tactical and as we’re making a model submarine, not the real thing, we don’t really need to bother with those. Bow diving planes are either placed on the bow (hull) or the sail (tower) of the submarine. Lower speeds require bigger angular rates, higher speeds require lesser. Diving planes manage to change the submarines pitch and depth only during the vessels movement and their efficiency is greatly effected but the boats speed. When the submarine is in a state of neutral buoyancy diving planes are used to control it’s pitch and the depth of the vessel. There are two types of those: Stern (rear) diving planes and bow (front) diving planes. Diving planes look a little like horizontally placed rudders. Watch the animation on the right to get the general idea.ĭiving planes: Submarines in addition to well known rudders are also equipped with something called “diving planes”. That causes the air to push the water out from the ballast tanks through the bottom openings of the ballast tanks and the submarine becomes positively buoyant again – can cruise on the surface. Finally, when the resurfacing order is given, compressed air is being blown into the tanks while the upper venting valves are CLOSED. Now the submarine has either neutral or negative buoyancy – it dives and can cruise under the waters surface. When the dive is ordered, the upper vents of the ballast tanks are being OPENED which causes the tanks to flood with water through the bottom openings. During that surface cruise submarine is in a state which is called a positive buoyancy, because its diving tanks are filled with air. All of those are connected with pressure tanks filled with compressed air, which is gathered and stored during the surface cruise. Everything is being controlled by lots of valves with lots of backup systems. Real submarines have complicated diving systems consisting of many ballast tanks, trimming tanks, auxiliary tanks, emergency tanks etc. To understand how a RC model submarine dives you need to understand how the real submarines manage it, just the general idea. – Sealing the moving parts of your model – shafts, pushrods etc. – Model types – static divers and dynamic divers ![]() Table of contents: – Submerging – absolute basics.
