A system was developed for stereophonic presentation of information (3-D sound) over high-fidelity headphones. The purpose was to reduce the pilot's response time to a localized threat. Physical parameters permitting the localization of sound are rev

Evaluation of cerebral stresses under acceleration taking into account the lateral ventricles

Autor: A, Guillaume, D, Osmont, A, Vartanian, D, Gaffie, V, Chastres, J C, Sarron, P, Quandieu

In certain flight configurations, fighter pilots are exposed to high Gz acceleration that may induce inflight loss of consciousness (LOC). That LOC is usually preceded by visual prodromes as greyout and blackout. The pathophysiological cause of these

Bovine brains were excised and placed into a transparent mold equipped with a pump and perfusion system. This unit was then centrifuged and changes in brain contour were video recorded. Analysis of the resulting images showed that changes occurred in

Modeling and numerical simulation of the cerebral blood flow under acceleration

Autor: D, Gaffié, A, Guillaume, P, Quandieu

Publikováno v: The Physiologist. 36

When fighter aircrafts change directions, the pilots are subject to a centrifuge force. This force can be enough to induce the pilot loss of consciousness (LOC). The physiological cause of this LOC is a brain hypoxia which results from the increase o

[Biomechanical interpretation of loss of consciousness (GLOC) by fighter pilots under rapid onset rate (ROR) of +Gz acceleration]

Autor: P, Quandieu, D, Gaffie, P, Liebaert

Publikováno v: Comptes rendus de l'Academie des sciences. Serie II, Mecanique, physique, chimie, sciences de l'univers, sciences de la terre. 312(1-3)

ROR +Gz acceleration withstood by fighter pilots generates GLOC, which is assumed to be related to cranial hypertension. Results derived from simple mathematical models seem to confirm this hypothesis.
