An air pressure wave which moves ahead of the main blast wave for some distance as a result of a nuclear explosion of appropriate yield and low burst height over a heat-absorbing (or dusty) surface. The pressure at the precursor front increases more gradually than in a true (or ideal) shock wave, so that the behaviour in the precursor region is said to be non-ideal. 2, record 2, English, - precursor%20front

Front de pression qui précède le front principal.

La pression sur le front précurseur augmente plus progressivement que celle d’une onde de choc théorique, aussi dit-on que les conditions au voisinage du front précurseur ne sont pas conformes au modèle calculé. 2, record 2, French, - front%20de%20pression%20pr%C3%A9curseur

Onda de presión en el aire que precede a la onda de choque principal. Se forma como resultado de una explosión nuclear de determinada potencia a baja altura. A medida que avanza forma una superficie que absorbe calor (o polvo). La presión del frente previo aumenta de forma más regular que la onda de choque teórica, de manera que se puede decir que su comportamiento no es el ideal. 1, record 2, Spanish, - frente%20previo%20de%20presi%C3%B3n

Si l'on forait un trou perpendiculaire au front de taille d’une excavation réalisée dans une masse rocheuse uniforme [...] et si l'on faisait exploser une charge dans ce trou, il n’ en résulterait presqu'aucun arrachement de roche, car toute la force de l'explosion serait orientée dans l'expulsion de la bourre et dans un certain morcellement et tassement de la roche autour du trou. Si, par contre, le trou foré est incliné par rapport au plan de taille [...], la roche, comprise entre le trou et la paroi, sera plus facilement soumise à l'arrachement du massif que dans le cas précédent, car dans cette direction la résistance de la roche à l'arrachement sera moins grande que dans les autres. 7, record 3, French, - trou%20inclin%C3%A9
