Record 1 2024-08-21

English

Subject field(s)
  • Ship and Boat Parts
  • Propulsion of Water-Craft
CONT

The foil is shaped in such a way that it generates lift as water flows over and under it. This lift counteracts the weight of the vessel, reducing the amount of hull surface area in contact with the water. As a result, hydrofoils decrease hydrodynamic drag, allowing the vessel to glide more efficiently through the water.

Key term(s)
  • hydro foil
  • hydro-foil

French

Domaine(s)
  • Parties des bateaux
  • Propulsion des bateaux
DEF

Aile profilée sur un côté [d'une embarcation] qui, une fois immergée, crée un phénomène de portance permettant [à l'embarcation] de s'élever au-dessus de l'eau.

OBS

foil : Bien que l'emprunt anglais «foil» soit répandu dans l'usage, il est recommandé de privilégier les termes «aile portante» ou «plan porteur».

Record 2 2022-05-31

English

Subject field(s)
  • Collaboration with the FAO
  • Commercial Fishing
CONT

The shape optimization approach of the cambered otter board has been performed by the integration of the neural network model and the multi-objective genetic algorithm... the excellent performance of the otter board is expressed by great lift and less drag force... The Bézier curve represented the cambered otter board as a simple structure with five control points... The hydrodynamic characteristics of [the] otter board models were calculated in a two-dimension computational fluid dynamics(CFD) analysis at an attack angle of 20 [degrees].

OBS

Of an otter trawl.

PHR

PHR

oval cambered double slotted otter board, oval cambered single slotted otter board

Key term(s)
  • cambered otterboard

Record 3 2007-07-12

English

Subject field(s)
  • Aeronautical Engineering and Maintenance
CONT

The horizontal component of the resulting hydrodynamic pressure force is termed "fluid-displacement drag" and the vertical component, "fluid-displacement lift. "Additional fluid forces termed "fluid-spray thrust or drag" and "fluid-spray lift" are created on aircraft when some of this displaced runway fluid in the form of spray sub-sequently impinges on other parts of the aircraft such as the tires, landing gear, and flaps.

Key term(s)
  • fluid displacement lift

French

Domaine(s)
  • Aérotechnique et maintenance
