The dynamic lift reduces the wetted surface and therefore also the drag.
In addition to static lift, an airship can obtain a certain amount of dynamic lift from its engines.
Some fish, such as sharks, use stiff, strong fins to create dynamic lift and propel themselves.
The great arc known as the monohull prevailed by virtue of its simplicity, buoyancy and dynamic lift.
The two bow rollers can be used together with linear hydraulic pullers to achieve a dynamic lift of 150 tons.
They can control their depth only by swimming (using dynamic lift); others store fats or oils for the purpose.
The stern rollers can be used with the automatic towing machine to provide a dynamic lift of 150 tons.
Fish without these features use dynamic lift instead.
The liver's effectiveness is limited, so sharks employ dynamic lift to maintain depth when not swimming.
The main challenge was the need to combine lighter weight with greater dynamic lift.
