Picture a wheel that transforms based on the surface it encounters. On a road, it’s a classic tire, offering grip and comfort. But as soon as it hits mud, snow, loose sand, or water, paddles emerge from its tread. These paddles are not mere gimmicks - they are the result of brilliant engineering, combining three fundamental physical principles:

-	Paddle Propulsion: At low speeds on water, the ARWIMS wheel behaves like a paddlewheel, delivering thrust with remarkable efficiency, far surpassing propellers in these conditions. Only the efficient part of the wheel is in the water or in the mud.
-	Hydrodynamic Lift: Thanks to the subtle tilt of the paddles, an upward force is generated, lifting the vehicle and reducing drag: t’s as if your wheels have invisible wings! This lift pulls vehicles out of mud or sand and minimizes water resistance as speed increases.
-	Controlled Aquaplaning: At higher speeds, ARWIMS turns the undesirable phenomenon of aquaplaning into an advantage. The tilted paddles allow the vehicle to glide on water, with its surface resistance becoming comparable to concrete. Yes, you read that right: driving at high speed on water is now a reality!

The system is designed for fully automatic adaptation.

-	No need to press a button or switch modes.
-	The paddles deploy when needed and retract on their own when they encounter obstacles like shallows or roads.
-	This intelligent synchronization, continuous geometry, and ability to adjust wheel height ensure smooth transitions and optimal stability in all conditions. - It is also possible to deploy only the blades located in a limited sector of a wheel. - This is particularly useful for wheels that are completely submerged. This is also a way to propel a submarine in any direction and determine its depth. This organization remains compatible with automatic retraction when a paddle encounters an obstacle.
