dynamic lift造句
例句與造句
- Some fish, such as sharks, use stiff, strong fins to create dynamic lift and propel themselves.
- Fish without these features use dynamic lift instead.
- In addition to static lift, an airship can obtain a certain amount of dynamic lift from its engines.
- The use of dynamic lift by pitching the nose of the airship up or down was also recognised and practised on this airship.
- Once the airship was cruising, the aircraft would be flown aboard, the additional weight being supported by dynamic lift until the airship lightened.
- It's difficult to find dynamic lift in a sentence. 用dynamic lift造句挺難的
- The original patent was for Kaydon's " Tapered Ramp " lift geometry, a " constant diameter / variable depth " dynamic lift design.
- The great arc known as the monohull prevailed by virtue of its simplicity, buoyancy and dynamic lift . For millenniums it ruled the waves.
- The US Navy Office of Naval Research gave Dr . Hoerner a contract in the mid-1960s to write a companion volume " Fluid-Dynamic Lift ".
- 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.
- 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.

- Aero-dynamic lift, drag, and thrust are all non-uniform forces ( they are applied at a point or surface, rather than acting on the entire mass of an object ), and thus create the phenomenon of weight.

- Dynamic lift in past airships has been about 10 % of the static lift . Dynamic lift allows an airship to " take off heavy " from a runway similar to fixed-wing and rotary-wing aircraft . However, this requires additional weight in engines, fuel and landing gear, negating some of the static lift capacity.
