Abstract: This invention relates to a maneuverable, ergonomically sound device for mechanics or technicians of all kinds to use in a variety of locations and situations. This invention has proven uses within the aviation industry, but could be used by technicians and mechanics in many other industries due to its flexible design and industrial-grade construction.  Mechanics must have access to many angles and locations on a vehicle or aircraft in order to service properly. This requirement often leads to uncomfortable positions for long periods of time.  Many technicians today use garden pads for body protection against concrete shop flooring or modified office chairs to maneuver comfortably in areas where neither sitting nor standing is appropriate. This personal positioning device allows mechanics and technicians to easily maneuver into a variety of positions from lying horizontal to a full sitting position without having to dismount, adjust and remount the device. This feature increases productivity and safety in these work environments.

Abstract: L'invention vise à améliorer les performances en accélération d'un générateur de gaz de turbine à gaz, en réduisant les prélèvements d'énergie électrique, en particulier pendant les phases transitoires, afin de conserver une marge au pompage suffisante pour la ligne de fonctionnement. Pour ce faire, l'invention prévoit d'augmenter le pouvoir d'accélération/décélération du générateur de gaz en régulant la tension du réseau électrique de bord de l'aéronef. Dans un mode de réalisation, après une phase de démarrage (50) de la turbine à gaz, le réseau de bord (10) est régulé en tension par une consigne de tension (CT) pilotée par une étape de détermination d'état (100) de délestage/lestage (EDEL, ELES, ESTAB) d'une source génératrice principale d'électricité (7) du réseau de bord (10). La détermination d'état (100) est effectuée en fonction de la demande de prélèvement de puissance (PPREL) à fournir à la propulsion de l'aéronef (41). Cette étape de détermination d'état est suivie d'une étape de sélection (200) d'une consigne de tension (CT) entre plusieurs niveaux (UH, UB, UM) en fonction de la détermination de l'état de délestage/lestage, et d'une étape d'application de la consigne sélectionnée (300) à une boucle de régulation de la tension (15) fournie au réseau de bord (10).
