Record 1 2016-03-06

English

Subject field(s)
  • Helicopters (Military)
  • Flight Instruments and Equipment (Aeroindustry)
DEF

The unequal lift across the rotor disk resulting from the difference in the velocity of air over the advancing blade half and the velocity of air over the retreating blade half of the rotor disk area.

OBS

dissymmetry of lift : term officially approved by the Aeronautical Terminology Standardization Committee(ATSC)-Helicopters.

French

Domaine(s)
  • Hélicoptères (Militaire)
  • Instruments et équipement de bord (Constructions aéronautiques)
OBS

Record 2 2011-02-11

English

Subject field(s)
  • Chemistry
DEF

When the scattering in the half plane from [phi] = 0° to 180° is symmetrical with that form [phi] = 180° to 360°, this term is defined as the ration of the scattered irradiance at two scattering angles symmetrical about [phi] = 90°.

OBS

The word "phi" must be replaced by the corresponding Greek letter.

Key term(s)
  • light scattering dissymmetry

French

Domaine(s)
  • Chimie
OBS

[Se dit de la lumière] lorsque la diffusion dans le demi-plan [phi] = 0 à 180° est symétrique par rapport à celle observée de [phi] = 180 à 360°, l'expression est définie comme le rapport de l'irradiance à deux angles de diffusion symétrique, avec [phi] = 90° environ.

OBS

Le mot «phi» doit être remplacé par la lettre grecque correspondante.

Record 4 2004-05-13

English

Subject field(s)
  • Helicopters (Military)
CONT

Cyclic feathering allows the pilot to keep the rotor disk tilted foward and, as it changes the angle of incidence on both the advancing and retreating sides, it also helps to compensate for dissymmetry of lift.

French

Domaine(s)
  • Hélicoptères (Militaire)
CONT

De nombreuses solutions seront apportées tout au long de l'évolution de l'hélicoptère, dans laquelle s'inscrira l'invention capitale de la variation cyclique de pas, qui permettra de modifier la position des pales à mesure de la rotation et de remédier ainsi à la dissymétrie engendrée par l'avance de l'engin.

Record 6 1995-10-16

English

Subject field(s)
  • Mathematics
  • Computer Graphics
CONT

the Bernoulli clusters themselves are fully known(at least in principle), hence modeling them via explicit recursive fractals is a different task. The Koch contact clusters I studied are not suitable, due to dissymmetry between vinyl and copper, even when there are equal numbers of sticks of both kinds.

CONT

Bernoulli percolation clusters are modeled via explicit recursive fractals.

French

Domaine(s)
  • Mathématiques
  • Infographie
OBS

Les transitions de percolations : la transition sol-gel où les macromolecules, en se soudant entre elles, forment un amas infini (gel). La théorie des amas de percolation s'est beaucoup développée.
