Some fish, such as sharks, use stiff, strong fins to create dynamic lift and propel themselves.
2.
Fish without these features use dynamic lift instead.
3.
In addition to static lift, an airship can obtain a certain amount of dynamic lift from its engines.
4.
The use of dynamic lift by pitching the nose of the airship up or down was also recognised and practised on this airship.
5.
Once the airship was cruising, the aircraft would be flown aboard, the additional weight being supported by dynamic lift until the airship lightened.
6.
The original patent was for Kaydon's " Tapered Ramp " lift geometry, a " constant diameter / variable depth " dynamic lift design.
7.
The great arc known as the monohull prevailed by virtue of its simplicity, buoyancy and dynamic lift . For millenniums it ruled the waves.
8.
The US Navy Office of Naval Research gave Dr . Hoerner a contract in the mid-1960s to write a companion volume " Fluid-Dynamic Lift ".
9.
The hybrid airship combines the airship's aerostatic lift, from a lighter-than-air gas such as helium, with the heavier-than-air craft's dynamic lift from movement through the air.
10.
The dynamic lift ); others store fats or oils with density less than that of seawater to produce a neutral or near neutral buoyancy, which does not change with depth.
